The reasons why our company is entrusted with solar panel installation by customers in Ashigarashimo District (Hakone Town, Manazuru Town, Yugawara Town)
“Our strengths in solar panel installation that cannot be imitated by other companies”
have received high praise from many customers.
We would appreciate it if you could compare our estimates with those of other companies.
Because we are confident, we welcome estimates from any number of companies!
1. We can also handle exterior renovations other than solar panel installation!
Troubles such as leaks caused by the installation of solar panels may be due to insufficient checks on the roof and waterproofing at the installation site.
Even if one is knowledgeable about solar panels, there are cases where the roof and waterproofing at the installation site are outside their expertise, so caution is necessary.
It is reassuring to have expertise in roofing to avoid maintenance issues and troubles after installation!
Kakeru Koumuten Co., Ltd. is strong in roofing work and can also detach and attach solar panels in-house, allowing for quick responses to maintenance and urgent troubles after solar panel installation!
2.Facilities Specialized in Exterior Renovation
Kakeru Koumuten Co., Ltd. has organized the following warehouses and material storage areas to provide low-cost, high-quality solar and exterior renovation work.
We have established five bases centered around Yokohama City, Kanagawa Prefecture for material storage and showrooms.
In-house Scaffolding Materials
To ensure safety during work on the roof, we own the scaffolding materials necessary for temporary scaffolding based on construction conditions and can assemble scaffolding in-house.
By not outsourcing scaffolding work and using our own scaffolding team, we can also reduce the costs associated with scaffolding work.
We own scaffolding materials for approximately 50 single-family homes!
Even if there are height differences on the site, our in-house scaffolding team will plan the scaffolding according to the local conditions.
Storage of Materials in Our Large Warehouse
We store roofing materials and paints, and we can also store removed solar panels.
By ordering a large quantity of materials at once, you canpurchase materials at a lower cost!
Additionally, we always have a stock of roofing materials, so we canrespond quickly in emergencies!
In-house sorting and transportation of waste materials
The installation of solar panels often involves roofing work, generating various waste materials such as paints, wood, and metal.
By sorting and recycling waste materials, we can significantly cut waste disposal costs.
Exterior renovation dedicated showroom
In the showroom, not only can you have meetings, but you can also
check the actual foundation brackets for solar panels and see how they are attached to the roofing materials!
We can also provide simulations of potential earnings and installation costs when introducing solar panels!
Since roofing and exterior wall work often accompany each other, we also have samples of roofing materials and models that explain the structure, allowing us to provide detailed explanations!
3.All work performed by our own team
One of Kakeru Koumuten’s major strengths is its complete in-house construction.
By having Kakeru Koumuten manage everything from inquiries to project completion in a consistent system, we can keep costs down while providing high-quality roof renovations.
Additionally, one representative will handle everything from the estimate to project completion.
Since the same person is responsible for sales and construction management, smooth communication is possible.
We can provide consistent in-house construction from temporary scaffolding installation to exterior wall painting and roof renovations!
4. Various Permits and Skilled Workers
We have obtained construction industry licenses as well as permits for industrial waste collection and transportation!
We also have nationally certified sheet metal workers and painting specialists, and we are confident in our construction techniques.
We can also handle large-scale roof projects for factories and other facilities!
5. Warranty and Aftercare
In addition to the manufacturer’s warranty for solar panel installation work, we also provide our own construction warranty (leakage warranty)!
(The construction warranty for solar panel installation is 10 years. Depending on the condition of the roof before installation, we may not be able to provide a warranty unless roof renovations are performed. The construction warranty is separate from the manufacturer’s product warranty, and the coverage and conditions vary based on the warranty details.)
Aftercare is available annually, and we send out reminder DM each year.
If you have questions about the warranty, please click on the image above!
6. Flexible and Prompt Response
Our company is equipped to handle various roofing troubles and situations.
Even if you cannot access the roof at high altitudes, we can respond using a drone!
During leak investigations, we can also conduct inspections using a thermal imaging camera.
If the power generation of your solar panels decreases due to dirt or other factors, we can also provide cleaning of the solar panels using a specialized brush.
We will respond according to your wishes.
7. Human Resource Development
To improve skills, we create various roof models and conduct practical training.
Since the construction methods change depending on the shape and slope of the roof, we regularly provide technical training so that each staff member can handle various cases.
8. Creation of Easy-to-Understand Materials and Simulations
Kakeru Koumuten provides not only “estimates,” “layout diagrams,” and “power generation simulations” but also a “solar construction guidebook” and a “profit and loss simulation” that takes into account loan interest rates and electricity costs.
The profit and loss simulation can be created for projected cumulative profits and losses over 20 to 30 years.
Even customers who are not familiar with solar construction can easily understand the materials, including points to note and disadvantages!
We encourage you to obtain comparative estimates and compare them with other companies’ plans!
Roof Inspection Before Installing Solar Panels
Once solar panels are installed, they will remain on the roof for 20 or 30 years.
Confirming “Is it okay to install them directly on the current roof?” before installation is the key point to prevent leaks and unnecessary expenses!
Kakeru Koumuten, which specializes in roofing work, has summarized the items to check before installation.
| 1. Types of Roofing Materials and Age | The fixing method varies depending on the roofing material, such as slate, tiles, metal roofs, and flat roofs (rooftop waterproofing). If the remaining lifespan of the roofing material is short, we may suggest roof renovation first. |
| 2. Condition of the Substrate and Waterproof Sheet | If the sheathing or roofing (waterproof sheet) beneath the roofing material is damaged, it can affect the fixing strength and waterproofing. We also check for any signs of leaks. |
| 3. Orientation, Slope, and Shadows of the Roof | The orientation and slope of the roof surface, as well as shadows from neighboring houses, trees, and utility poles, can affect power generation. We create a layout diagram from the drawings and the site, and you can check it with a power generation simulation. |
| 4. Shape of the Roof and Usable Area | The number of panels (installation capacity) that can be placed depends on the shape and size of the roof. Since the number of panels that can be installed varies depending on the panel size, we compare based on the total output of the roof. |
| 5. Fixing Method and Waterproofing Details | We check whether the method involves drilling holes in the roofing material for fixing or using brackets to secure the roofing material. The fixing method varies by technique, so please confirm the waterproofing treatment of the fixing parts during the estimate. |
| 6. Weight of the Roof | The roof becomes heavier due to the panels being added. After investigating the existing roof, substrate, and load capacity, switching to lighter roofing materials may also be an option if necessary. |
| 7. Location of Equipment Installation and Wiring | We check the installation location of the power conditioner and storage battery, as well as the wiring route to the distribution board. The length of the wiring also affects costs. |
| 8. Ease of Scaffolding Setup and Delivery Routes | If there are height differences on the site, planning for scaffolding and delivery routes for equipment and materials may require some ingenuity. The width of the front road and any steps on the site are also confirmed during the site survey. |
Fixing Methods and Checkpoints by Roofing Material
| Roof Material | Main Fixing Method | Pre-Installation Check Points |
|---|---|---|
| Slate Roof | Varies by method (e.g., fixing brackets to the roof material and substrate with screws) | Waterproofing treatment of fixing parts, cracks or deterioration of slate, condition of the substrate. If deterioration is significant, consider roof overlay (cover method) or replacement first. |
| Tile Roof | Fixed with brackets and methods suited to the type of tile (even methods that do not drill holes in the tiles will secure to the substrate) | Type and condition of tiles, substrate, load-bearing capacity. Depending on the investigation results, there may be methods to replace with lighter roofing materials before installation. |
| Metal Roof (Horizontal and Vertical) | Fixed with catch-type brackets that grip the roof material (depends on the combination of roof material and brackets) | Whether the roof material and brackets are compatible, installation conditions from the roof material manufacturer. If compatible, methods that do not drill holes may be available. |
| Flat Roof / Rooftop | Fixed by installing a framework | Type and deterioration status of the waterproof layer, waterproofing around the framework. Consider in conjunction with the timing of waterproofing work. |
If you perform roof renovations 10 to 20 years after installation, additional costs for removing and reinstalling solar panels will apply. If the roof is deteriorating, renovating to a highly durable roofing material before installation may help reduce costs in the long run.
Kakeru Koumuten Co., Ltd. specializes in roofing work and can also handle the removal and reinstallation of solar panels in-house, so please consult us according to the condition of your roof!

Breakdown of Installation Capacity, Equipment, and Construction Costs
The costs for solar panels and batteries should be checked separately for “Equipment Costs (Device Costs)” and “Construction Costs.”
Even for the same “Complete Solar Panel Installation,” the amount can vary significantly depending on the installation capacity, equipment grade, and roof condition.
Considerations for Installation Capacity (kW) and Battery Capacity (kWh)
The installation capacity of solar panels is determined by “Output of One Panel (W) × Number of Panels”, with the unit being kW (kilowatts). Batteries are compared based on the amount of electricity they can store, expressed in kWh (kilowatt-hours).
The amount of kW that can be installed on a roof varies for each house based on the roof’s shape, orientation, and size. At Kakeru Koumuten, we create layout diagrams from blueprints and on-site surveys to present the installation capacity.
On our pricing page, we list solar panel costs as approximately 800,000 JPY to 1,200,000 JPY for 3-5 kW and 1,200,000 JPY to 1,900,000 JPY for 6-10 kW. (These are just approximate amounts and can vary based on wiring length, scaffolding range, existing roofing materials, panel layout, etc.)

Items to Confirm in the Estimate (Cost Confirmation)
When comparing estimates from different companies, it’s common to compare items with different capacities and equipment. Please check if the following items are clearly stated in each company’s estimate!
| 1. Solar Panels | Manufacturer, model number, output per panel (W), number of panels, total installation capacity (kW) are specified. |
| 2. Power Conditioner | Manufacturer, model number, capacity, number of units, installation location (indoor/outdoor). Also confirm whether it is a type that controls in conjunction with a battery. |
| 3. Battery | Manufacturer, model number, capacity (kWh), range of use during power outages (entire house or specific circuits), installation location. |
| 4. Mounting Frame and Hardware | Name of the hardware suitable for the roofing material and the method of securing it (whether it involves drilling holes or using clamps). |
| 5. Wiring and Electrical Work | Wiring route and length, work around the distribution board, presence of a monitor to check power generation. |
| 6. Roof Reinforcement and Waterproofing | Details of waterproofing treatment at the fixed parts, whether necessary roof repairs and substrate reinforcements are included. |
| 7. Applications | How much support is included for applications to the power company, certification applications for selling electricity (FIT), and subsidy applications. |
| 8. Scaffolding | Scope and quantity of scaffolding. If roof work and exterior painting are done simultaneously, check that the same scope and quantity are not double-counted. |
| 9. Removal and Disposal | Whether the removal of existing solar water heaters and old panels, as well as disposal costs for waste materials, are included. |
| 10. Tax Classification and Warranty | Whether the price is tax-inclusive or tax-exclusive, conditions under which additional costs may arise, and details and duration of manufacturer and workmanship warranties. |
If the capacities differ, both the price and power generation will change. Kakeru Koumuten Co., Ltd. welcome comparisons of estimates, so if you bring estimates from other companies, we will explain the differences item by item!
Self-Estimate and Profit Simulation for Solar Power Generation
With the simulator above,
you can obtain an approximate estimate and a profit simulation for up to 30 years!
If you know the total installation capacity of solar panels on the roof and the capacity of the battery, you can get an approximate estimate and profit simulation!
*The simulation results are approximate. Actual profits may vary based on assumptions such as electricity rates, self-consumption ratios, selling prices, and costs for equipment inspection or replacement.

How to Choose a Solar Panel Installation Contractor in Ashigarakami District (Hakone Town, Manazuru Town, Yugawara Town)
There are many solar panel installation contractors available in Ashigarashimo District (Hakone Town, Manazuru Town, Yugawara Town), and it can be confusing to choose which contractor to go with.
Therefore, when requesting solar panel installation and battery storage installation work, let’s check the following 4 points.
● Have extensive knowledge not only about solar panels but also about roofs
● Confirm the presence of warranties and aftercare maintenance
● Obtain estimates from multiple contractors (3 companies is a guideline)
● Check if they provide support for subsidy applications
By confirming the above 4 points, you will be able to choose a reliable contractor.
Knowledge about roofs as well as solar panels
Improper installation of solar panels can sometimes be caused by a lack of knowledge and verification regarding roofs and waterproofing.
While knowledge about solar panels is certainly important, understanding the roof and waterproofing at the installation site of the solar panels is also crucial.
⚠︎Examples of troubles caused by insufficient verification of roofs and waterproofing
・Installing solar panels on a severely deteriorated roof, resulting in leaks
・Installing solar panels on a roof with a short lifespan, necessitating renovations to detach and reattach the solar panels within a few years
・Misjudging the type of waterproofing and performing incorrect treatment, leading to leaks
and more
When installing solar panels, understanding the condition and type of the existing roof allows for installation that avoids unnecessary expenses and unforeseen troubles.
▶ Go to “Roof Verification Before Installing Solar Panels” in this article
Confirm the presence of warranties and aftercare maintenance
When choosing a solar installation contractor, let’s confirm the presence of warranties. It is important to check not only the duration of the warranty but also the coverage, exclusions, and cost conditions.
Solar panels and battery storage units come with manufacturer warranties, but also check for the presence of installation warranties in case leaks occur after installation!
For contractors that offer installation warranties, if leaks occur after installation, they may be able to respond under the warranty if it is within the warranty period and conditions.
Additionally, some contractors offer after-service separate from the warranty, so be sure to check if the contractor you are considering has after-service.
Changes or damage on the roof can be in areas that are not visible, so there is a possibility that customers may not notice them.
By conducting inspections in after-maintenance, even in areas that are not visible, it becomes easier to prevent major repairs or breakdowns by discovering abnormalities early!
Kakeru Koumuten Co., Ltd. provides a rain leak warranty as part of the workmanship warranty for solar panel installations. (The warranty for solar panel installations is 10 years, and depending on the condition of the roof before installation, a roof renovation may be required to provide the warranty.)
We also conduct after-maintenance and send out DM every year!
Please check the DM, and if you wish, we will visit you for after-maintenance!
Obtain estimates from multiple contractors (3 companies as a guideline)
When requesting solar panel installation, be sure to obtain estimates from multiple contractors.
Even for the same manufacturer and the same construction content, costs may vary, and warranties and after-services may differ.
Additionally, obtaining multiple estimates makes it easier to negotiate prices.
To request from your preferred contractor at a lower price, we recommend obtaining estimates from multiple contractors.
When comparing estimates, please check carefully the following:
“Check the items in the estimate”

Check if they provide support for subsidy applications
Subsidies may be available for solar panel installations and battery installations, but if the order of procedures is incorrect or if there are deficiencies in the documents, the subsidy may not be granted.
For systems like Kanagawa Prefecture’s housing subsidies, where application by the contractor is not allowed and personal application is required, it is reassuring to have a contractor who can support the preparation of necessary documents and the flow of procedures.
Be sure to complete the procedures specified for each system (for the prefectural housing subsidy, this means obtaining a grant decision) before proceeding with the construction!
For the prefectural housing subsidy, after the construction is completed, a performance report must be submitted, and it will go through a review before the grant is provided! (The flow of procedures varies by system)
Benefits of Introducing Solar Power Systems
The benefits of installing solar panels are summarized in the following 5 points!
Benefit 1: Economic Advantage
The biggest advantage of installing solar panels is the economic benefit!
While the selling price of electricity has decreased compared to 10 years ago, you can gain benefits by reducing the electricity you buy from power companies through self-consumption of generated power!
As electricity costs rise, the ability to cover your power consumption with solar power becomes increasingly attractive!
If you plan to use the generated power at night, installing a storage battery is essential!
Furthermore, the selling price (FIT) for residential use (under 10kW) will be set at “24 yen/kWh for the first 4 years, and 8.3 yen/kWh from the 5th to the 10th year” for certifications after October 2025, and the same price will apply for the 2026 fiscal year. After the 5th year, it is generally more advantageous to use it at home (self-consumption), making the combination with a storage battery a viable option.

Benefit 2 Utilizing Subsidies!
The conditions and amounts of subsidies vary by prefecture and municipality, but if you meet the requirements, you may be able to utilize subsidies!
Reducing the actual burden through subsidies is a significant advantage!
In the case of Ashigarashimo District, there may be applicable programs from the national government, Kanagawa Prefecture, and your local town (please check the application status for each program).
Benefit 3 Environmentally Friendly!
Solar power generation has low carbon dioxide emissions and can reduce dependence on fossil fuels, contributing to the mitigation of global warming.
Since solar panels themselves do not produce noise or exhaust gases during the generation process, they are considered an environmentally friendly method of power generation. (However, devices like power conditioners may produce operational noise.)
Benefit 4 Expected Heat Insulation Effect!!
By installing panels on the roof or rooftop, they block direct sunlight from hitting the roof.
Especially in summer, it can help reduce the temperature rise of the roof, providing expected heat insulation effects!
(Note that this does not improve the building’s insulation performance itself.)
Benefit 5 Electricity can be used even during power outages!!
If a storage battery is installed, it becomes possible to use electricity even during emergencies such as power outages!
Even without a storage battery, if you have a power conditioner with autonomous operation capabilities, you may be able to use electricity from a dedicated outlet during daytime generation.
(Note that the devices, output, and time that can be used during a power outage vary depending on the model and wiring method.)
What points should be noted when introducing solar power generation?
Next, we will explain the “three points to note” when installing solar panels!
Point 1 Maintenance costs are incurred
A particularly overlooked maintenance cost is for the roof where solar panels are installed.
If you perform roof renovations 10 to 20 years later, there will be costs for removing and reattaching the solar panels.
If the existing roof is deteriorating, it is reassuring to renovate it with durable roofing materials before installing solar panels!
Additionally, there will be costs for regular inspections of the equipment, repairs or replacements of the power conditioner, and updates due to the deterioration of the storage battery.
It would be reassuring to consider maintenance costs in simulations before introducing solar panels!
Point 2 The risk of leaks increases depending on the roofing material
The fixing methods for slate roofs and tile roofs vary by construction method, but when fixing hardware with screws to the roofing material or substrate, waterproofing of the fixed parts is crucial.
In methods that involve making holes in the roof, the risk of leaks inevitably arises.
Of course, we will ensure proper waterproofing, but if you are concerned about making holes, one option is to replace the roofing material with a metal roof and fix the solar panels using the catch method. (The catch method has compatibility conditions between the roofing material and hardware, and it cannot be used with all metal roofs.)
Base metal fittings for horizontal metal roofs
Note 3: The roof will become heavier
Since solar panels will be installed, the roof will become heavier. After investigating the existing roof, substrate, and load capacity, switching to a lightweight roof may also be an option if necessary.
How to Choose Solar Panels?
There are many manufacturers of solar panels, and their output and costs vary.
It is not simply a matter of “this manufacturer has the best solar panels”; it is important to choose solar panels that are suitable for your life plan and building!
Here are some points to consider when comparing solar panels!
Choosing Method 1: Compare by Overall Roof Output
When installing solar panels on the roof, it is important to know how much power can be generated in a limited area, and the more power generated, the better!
The sizes and outputs of solar panels vary by manufacturer.
A panel with 350W output and a panel with 400W output may seem that the one with higher output is better at first glance.
However, if the size of the panel does not fit well with the roof, there may be cases where “20 panels of 350W can be installed” and “15 panels of 400W can be installed,” leading to different installation capacities on the same roof due to the size difference of the panels.
400W × 15 panels = 6kW (total output of the roof)
350W × 20 panels = 7kW (total output of the roof)
As shown above, even if the output of a single panel is lower, the total output of the roof may be higher!
It is important to consider the overall output of the roof rather than the output of a single panel!
*The above is the calculation of total output (kW). The actual power generation amount (kWh) will vary depending on conditions such as the roof’s orientation, slope, and shading.
Choosing Method 2: Compare by Degradation Rate of Solar Panels
Solar panels have a degradation rate, and their output gradually decreases after 10 years and 20 years.
The degree of output decline after long-term use varies by product. The manufacturer’s output guarantee value is a standard figure for the warranty and does not indicate the actual degradation rate or power generation amount.
By considering the degradation rate as well as the initial output, you can choose solar panels without regrets!
Choosing Method 3: Compare by Warranty Period
There are several types of warranties for solar panels, including “output warranty,” “natural disaster warranty,” and “system warranty,” and the warranty periods vary by manufacturer.
Regarding output warranties, some manufacturers offer a 30-year warranty while others offer a 10-year warranty, so it varies!
A longer warranty is always better, so be sure to check the warranty period and conditions of the manufacturers you are considering!
Frequently Asked Questions about Solar Power and Storage Battery Installation in Ashigarashimo District (Hakone Town, Manazuru Town, Yugawara Town)
We have compiled frequently asked questions from customers considering the installation of solar panels and storage batteries in Ashigarashimo District (Hakone Town, Manazuru Town, Yugawara Town). (Tap to open the answers)
How much does it cost to install solar panels and storage batteries in Ashigarashimo District (Hakone Town, Manazuru Town, Yugawara Town)?
The cost varies depending on the installation capacity, equipment, and roof condition. In the above construction example (solar panel 4.3kW + storage battery, completed in April 2025), it was 2.2 million yen to 2.3 million yen.
Estimated costs by capacity are published on the solar panel and storage battery installation pricing page. We will create a layout diagram from the drawings and site survey and provide a free estimate!
Are there any subsidies available for solar power and storage battery installation in Ashigarashimo District (Hakone Town, Manazuru Town, Yugawara Town)?
As of October 6, 2026, the “Renewable Energy Equipment Installation Subsidy” in Hakone Town (15,000 yen per kW for solar power, with a maximum of 50,000 yen, and a maximum of 50,000 yen for storage batteries) and the “Residential Smart Energy Equipment Installation Subsidy” in Yugawara Town (15,000 yen per kW for solar power, with a maximum of 52,000 yen, and for storage batteries, within half of the installation cost, with a maximum of 50,000 yen) are listed on the town’s official pages. I could not confirm any residential subsidy system for Manazuru Town on the official page. The application status for the Reiwa 8 fiscal year varies by town, so please check with each town before contracting. The Kanagawa Prefecture subsidy (70,000 yen/kW for solar power and 150,000 yen per unit for storage batteries) reached its budget limit on September 7 for the second phase of the Reiwa 8 fiscal year and has been closed, and the national DR household storage battery project has ended its public recruitment.
Since the application status changes, please refer to the subsidy and grant section and consult with us before contracting.
Can I apply for subsidies after the construction is completed?
This depends on the system. The subsidy in Hakone Town requires application before the start of construction, while the subsidy in Yugawara Town requires notification to the Environmental Division before installation and application for disbursement after installation. On the other hand, the residential subsidy in Kanagawa Prefecture requires “starting construction after the grant decision,” and if construction starts beforehand, it will be excluded from eligibility.
The order of procedures varies by system, so please confirm before contracting and starting construction.
Can solar panels be installed on a slate roof? I’m worried about leaks.
Installation on a slate roof is possible, but it requires checking the condition of the roofing material and substrate. The fixing method varies by construction method, and if the method involves fixing brackets to the roofing material or substrate, waterproofing treatment of the fixed parts is essential.
Kakeru Koumuten Co., Ltd. is a specialized exterior renovation company strong in roofing work, so we will check the condition of the roof before installation and suggest methods such as roof overlay (cover method) or replacement if deterioration is progressing.
My roof is old. Should I do a roof renovation first?
It depends on the condition of the roof. If a roof renovation is needed after 10 to 20 years of installation, there will be additional costs for removing and reinstalling solar panels. If the remaining lifespan of the roof is short, it may be more cost-effective to renovate with durable roofing materials before installation.
Please consult us about the installation process after checking the condition of the roof during the on-site survey!
Should I install a storage battery together with the solar panels?
If you want to use the generated electricity at night or prepare for power outages, simultaneous installation is recommended. The selling price for electricity will be 8.3 yen/kWh after the fifth year, making it more advantageous to use it in your home rather than selling it.
Additionally, Kanagawa Prefecture’s subsidies require the simultaneous introduction of solar panels and storage batteries, and in the subsidies for Hakone Town and Yugawara Town, storage batteries are designated as eligible equipment (Hakone Town has a limit of 50,000 yen, and Yugawara Town covers up to half of the installation cost, with a limit of 50,000 yen). You can compare “solar panels only” and “solar panels + storage batteries” through a financial simulation.
How many kW can I install on my roof? Is it okay for north-facing or shaded roofs?
The capacity that can be installed varies depending on the shape, orientation, and size of the roof. At Kakeru Koumuten, we create a layout diagram from the drawings and on-site survey, and provide you with the installation capacity and power generation simulation.
In Ashigarakami District, the terrain varies by town, such as the mountainous area of Hakone Town, the peninsula of Manazuru Town, and the coastal and mountainous areas of Yugawara Town, which affects the shading from surrounding buildings and trees, as well as the installable capacity for each house. You can check the expected power generation through the power generation simulation.
How long will the construction period be?
For the above construction example (solar panels 4.3 kW + storage battery), it took about 3 days. The duration may vary if roofing work is done simultaneously or depending on the roof shape and installation capacity.
Additionally, please note that there will be a separate period for applications for subsidies and power companies, so please consult us as soon as possible.
What is the current selling price (FIT)?
For residential use (less than 10 kW), from the certification after October 2025, the first 4 years will be 24 yen/kWh, and from the 5th to the 10th year it will be 8.3 yen/kWh, and the same price will apply in the 2026 fiscal year.
The idea is to recover the initial costs quickly in the first 4 years and then focus on self-consumption. Kakeru Koumuten provides a financial simulation considering loan interest rates and electricity prices.
Can you take care of maintenance and inspections after installation?
Yes, we can. Kakeru Koumuten sends out annual after-maintenance DM notices and visits customers who wish for inspections. We can also handle cleaning solar panels with a special brush if the power generation decreases due to dirt.
The roof is a place that is difficult to check by yourself, so please feel free to consult us if you have any concerns.
Can you also handle renovations for roofs that already have solar panels installed?
Yes, it is possible. Kakeru Koumuten Co., Ltd. can detach and reattach solar panels in-house, allowing us to perform roof overlay (cover method) or re-roofing after removing the panels, and then reinstall them consistently. The removed panels can be stored in our own warehouse.
For costs, please refer to the solar panel detachment and water heater removal pricing page.

Features of Ashigarashimo District (Hakone Town, Manazuru Town, Yugawara Town) and points for solar work
Ashigarakami District consists of three towns: Hakone, Manazuru, and Yugawara. Hakone Town features a rugged volcanic terrain shaped by the complex formation history of the Hakone volcano, with elevations ranging from 97m in Yumoto to 1,438m at Kamiyama. Manazuru Town is a small peninsula approximately 7km long and 1km wide, protruding from the southeastern outer rim of the Hakone volcano into Sagami Bay, while Yugawara Town is surrounded by mountains on three sides, consisting of hilly areas, flatlands around the Chitose and Shinasaki rivers, and coastline. We have summarized the characteristics of Ashigarakami District’s terrain and key points to consider when installing solar panels and storage batteries below. (Tap to open)
View the characteristics of Ashigarakami District (Hakone, Manazuru, Yugawara) and points for solar construction
■ Mountainous Hakone Town, peninsula Manazuru Town, and Yugawara Town nestled between the sea and mountains. Confirm site and delivery routes on-site
Hakone Town features diverse volcanic terrain due to the Hakone volcano, and Manazuru Town has townscapes on sloped land facing the sea. Yugawara Town also has a terrain where hilly areas and flatlands are adjacent to the coastline. Even within the same town, the height differences of each site and the width of the front road will affect the planning of scaffolding and the delivery routes for equipment and materials such as panels and storage batteries. Kakeru Koumuten plans scaffolding tailored to the site, even when there are height differences, using its own scaffolding team and materials.
■ In Hakone Town, where there is a significant elevation difference, check temperature, precipitation, and snowfall by location
The annual average temperature in Hakone Town in 2018 was 16.4°C in Yumoto and 12.5°C in Sengokuhara, showing differences based on elevation. The annual precipitation is also different, with Yumoto receiving 2,822.5mm and Sengokuhara 3,580.5mm, where snowfall has also been recorded. Since conditions vary even within Hakone Town, it is important to check the roof slope and surrounding environment before installation, and to confirm the installation conditions such as snowfall for your residence according to the manufacturer’s standards. On the other hand, Manazuru Town is warm even in winter due to the Kuroshio current, and Yugawara Town is described as warm in winter and relatively cool in summer.
■ Manazuru and Yugawara Towns, close to the sea, confirm installation conditions for equipment based on manufacturer standards
Manazuru Town is a peninsula that juts out into Sagami Bay, while Yugawara Town has a coastline facing Sagami Nada. In areas close to the sea, installation conditions for panels, frames, and fittings may be specified for each product (handling in salt damage areas). The response may vary depending on the distance from the coast, so please check the installation conditions of the manufacturer being used when requesting a quote.
■ Roof types and ages vary from house to house. Check the roof and waterproofing before installation
Even in regions with similar topography, roof types, ages, and sunlight exposure vary from house to house. At Kakeru Koumuten Co., Ltd., we will check the type and condition of the roof and the site situation before installation and propose methods for securing, waterproofing details, and scaffolding plans.
■ The annual sunshine hours in neighboring Odawara is about 1,945 hours
Hakone Town, Manazuru Town, and Yugawara Town all border Odawara City. According to the Japan Meteorological Agency’s average values (1991-2020), the annual sunshine hours in Odawara is about 1,945 hours, with August (about 202 hours) being the most and June during the rainy season (about 131 hours) being the least.
The power generation in Ashigarashimo District can also vary due to elevation and the shadows of surrounding mountains and buildings, so conducting a year-round power generation simulation and selecting battery capacity to match peak electricity usage times are key points.
Our company is based in Kanagawa Prefecture and handles many exterior construction and solar power projects in Ashigarashimo District (Hakone Town, Manazuru Town, Yugawara Town).
We are happy to assist with partial roof repairs such as roof overlay work, roof replacement, and leak repairs, as well as other repairs! Please feel free to consult us about any sudden troubles!
