this information will definitely be helpful, so please take a look!
Reasons why Kakeru Koumuten is chosen for solar panel installations in Atsugi City, Kanagawa Prefecture
One reason why our company is entrusted with solar panel installations by customers in Atsugi City is that “we have a base within Kanagawa Prefecture,” but “our unique strengths in solar panel installation that cannot be imitated by other companies” have also received high praise from many customers.
In the installation work of solar panels in Atsugi City, we have absolute confidence in “cost,” “quality,” “plan”.
We would be grateful if you could compare our estimates with those of other companies.
Since we are confident, we welcome estimates from any number of companies!
1. We also handle exterior renovations other than solar panel installation!
Most troubles such as leaks caused by solar panel installation are due to the lack of knowledge of the solar panel installation contractors.
While contractors specializing in solar panel installation have knowledge about solar panels, it is a reality that many lack knowledge about the roof and waterproofing at the installation site.
It is safer to have someone knowledgeable about roofs to avoid maintenance issues and troubles after construction!
Kakeru Koumuten Co., Ltd. is strong in roofing work and can also detach and attach solar panels in-house, allowing us to respond quickly to maintenance and urgent troubles after solar panel installation!
2. Specialized equipment for exterior renovations
Kakeru Koumuten Co., Ltd. has prepared the following warehouses and material storage areas to provide solar work and exterior renovations at low cost and high quality.
We have established five bases centered around Yokohama City, Kanagawa Prefecture for material storage and showrooms.
In-house ownership of scaffolding materials
We own the scaffolding materials necessary for temporary scaffolding required for solar panel installation work, allowing us to assemble the scaffolding ourselves.
By conducting the scaffolding work with our own scaffolding team instead of outsourcing, we can also cut costs on scaffolding work expenses. We have approximately enough scaffolding materials for 50 single-family homes!
Storage of materials in our large in-house warehouse
We store roofing materials and paints, and we can also store removed solar panels.
By ordering a large quantity of materials at once, we can purchase materials at a lower cost!
Additionally, we always have a stock of roofing materials, allowing us to respond quickly in emergencies!
Separation and transportation of waste materials in-house
The installation of solar panels often involves roofing work, generating various types of waste materials such as paint, wood, and metal.
While most contractors dispose of these materials all together, significant cost savings on waste disposal can be achieved by sorting and recycling the waste materials.
Exterior Renovation Dedicated Showroom
In our showroom, not only can you have meetings, but you can also check the actual foundation brackets for solar panels and see how they are installed on the roofing materials! We can also provide simulations for the potential revenue and installation costs if you decide to implement solar panels!
Since roofing work and exterior wall work often go hand in hand, we have samples of roofing materials and models that explain the structure, allowing us to provide detailed explanations!
3．Complete In-House Construction
One of Kakeru Koumuten’s major strengths is our complete in-house construction.
From inquiry to project completion, everything is handled by Kakeru Koumuten Co., Ltd. This allows us to keep costs down while providing high-quality roof renovations.
Additionally, one representative will assist you from the estimate to the completion of the work.
Since the same person handles everything, including sales and construction management, smooth communication is possible.
We can provide consistent in-house construction from temporary scaffolding setup to exterior wall painting and roof renovations!
4. Various Permits Obtained & Skilled Workers on Staff
We have obtained construction industry permits and permits for industrial waste collection and transportation!
We also have nationally certified sheet metal workers and painting specialists on staff, giving us confidence in our construction techniques.
We are capable of handling large-scale roofing projects such as those for factories!
5. Warranty and Aftercare
In addition to the manufacturer’s warranty for solar panel installation, we also provide our own rain leak warranty! Aftercare is available annually, and we send out notification DM every year.
If you have any questions about the warranty, please click on the image above!
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 rain leak investigations, we can also conduct inspections using a thermal imaging camera.
If the power generation of the solar panels decreases due to dirt, we can also provide cleaning with a specialized brush.
We will respond according to your preferences.
7. Human Resource Development
We are creating various roof models to improve our skills and conducting practical training.
Since the construction methods vary depending on the shape and slope of the roof, we regularly provide technical training to ensure that all staff can handle various cases.

How to Choose a Solar Panel Installation Contractor in Atsugi City, Kanagawa Prefecture
There are many solar panel installation contractors that serve Atsugi City, and you may be unsure which one to choose.
Therefore,when requesting solar panel installation contractors or battery installation work, let’s confirm the following 4 points.
● Not only knowledgeable about solar panels but also have extensive knowledge about roofs
● Confirm the presence of warranties and aftercare services
● Obtain estimates from multiple contractors (at least 3 companies)
● Check if they provide support for subsidy applications
By confirming the above 4 points, you will be able to choose a reliable contractor.
Many causes of poor installation of solar panels stem from a lack of knowledge on the part of the contractor.
While knowledge of solar panels is certainly important, understanding the roof and waterproofing at the installation site is also crucial.
⚠︎Examples of troubles due to contractor’s lack of knowledge
・Installed solar panels on a deteriorated roof, leading to leaks..
・Installed solar panels on a roof with a short lifespan, requiring a costly renovation for removal and reinstallation within a few years..
・Misjudged the type of waterproofing, resulting in incorrect treatment and subsequent leaks..
and more
When installing solar panels, understanding the condition and type of the existing roof allows you to avoid unnecessary expenses and unexpected troubles.
Confirm the presence of warranties and aftercare services
When choosing a solar installation contractor, make sure to check for warranties.
While solar panels and batteries come with manufacturer warranties, also confirm whether there is a construction warranty in case of leaks after installation!
If the contractor offers a warranty period, they will respond free of charge in the event of leaks after installation.
Additionally, some contractors offer aftercare services separate from warranties, so be sure to check if the contractor you are considering has aftercare services.
Since abnormalities or damage on the roof may not be visible, you might not notice them yourself.
By conducting inspections during aftercare, you can detect issues early and prevent major repairs or breakdowns!
Kakeru Koumuten Co., Ltd. provides a leak warranty as part of the construction warranty for solar panel installations.
We also offer aftercare services and send out annual DM notifications!
Please check the DM, and if you wish, we will come to provide aftercare services!
Obtain estimates from multiple contractors (at least 3 companies)
When requesting solar panel installation, be sure to obtain estimates from multiple contractors.
Even if the same manufacturer provides the same type of work, costs may vary, as well as warranties and after-sales services.
Additionally, obtaining multiple estimates makes it easier to negotiate prices.
To request your preferred repair contractor at a lower cost, it is essential to obtain estimates from multiple contractors.
When comparing estimates, please check carefully the following:
“Verification of estimate items”
“Types of solar panels”
“Warranties and after-sales services”
Make sure to compare these details closely! If the quality of the materials is low or if steps are skipped, costs can be reduced, so avoid making decisions based solely on price!
Check if they provide support for subsidy applications
Subsidies are often available for the installation of solar panels and storage batteries, but there is a possibility that they may not be granted due to application errors.
If you proceed with the support of the contractor, there should be no issues with the application.
Make sure to apply for the subsidy before starting construction and proceed with the work only after it has been accepted!
After the construction, the flow will be that the subsidy will be decided and granted!
Benefits of Introducing Solar Power Equipment
The benefits of installing solar panels are summarized in the following five points!
Benefit 1: Economic Benefits
The biggest advantage of installing solar panels is the economic benefit!
While the selling price of electricity has decreased compared to ten years ago, the rising electricity costs allow you to benefit from consuming the power you generate!
Electricity prices are expected to continue rising, making it attractive to cover your consumption with solar power!
If you plan to use the generated power at night, installing a storage battery is essential!
Benefit 2: Subsidies can be utilized!
Subsidy conditions and amounts vary by prefecture and municipality, but there is a high probability that subsidy applications can be made!
Reducing the actual burden amount through subsidies is a significant advantage!
Benefit 3: Environmentally Friendly!
Solar power generation contributes to mitigating global warming by reducing carbon dioxide emissions and dependence on fossil fuels.
It is considered an environmentally friendly method of power generation as it does not produce noise or harmful substances during the process.
Benefit 4 Improved Insulation Effect!!
By installing it on the roof or rooftop, insulation properties are enhanced.
Especially in summer, it can effectively block direct sunlight, providing significant heat shielding benefits!
Benefit 5 Electricity can be used even during power outages!!
By installing a storage battery, it becomes possible to use electricity even during emergencies such as power outages!
What points should you be aware of when introducing solar power generation?
Next, we will explain the “three points to be cautious about” when installing solar panels!
Caution Point 1: Maintenance costs may be incurred
Maintenance costs are related more to the roof where the solar panels are installed rather than the solar panels themselves. If you perform a roof renovation 10 to 20 years later, there will be costs associated with removing and reinstalling the solar panels.
If the existing roof is deteriorating, it is reassuring to renovate it with durable roofing materials before installing the solar panels!
It would be comforting to request a simulation that takes maintenance costs into account before introducing solar panels!
Caution Point 2: The risk of leaks may increase depending on the roofing material
Slate roofs and tile roofs require holes to be made in the roof to secure solar panels.
As a result of making holes in the roof, there is inevitably a risk of leaks.
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 secure the solar panels using the catch method.

Note 3: The Roof Will Become Heavier
With the installation of solar panels, the roof will become heavier. In the case of tile roofs, it may be reassuring to replace them with lighter roofing materials.
There are many manufacturers of solar panels, and their output (power generation) and costs vary.
It is not simply a matter of “This manufacturer has the best solar panels”; what is important is 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 Based on Total Power Generation of the Roof
When installing solar panels on the roof, it is important to consider how much power can be generated in a limited area, and the more power generated, the better!
Solar panels come in various sizes depending on the manufacturer, and their power generation also differs.
For example, a 350W output panel and a 400W output panel may seem that the higher output panel 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 power output of the roof) 350W × 20 panels = 7kW (total power 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 total output of the roof rather than just the output of a single panel!
Choosing Method 2: Compare Based on Degradation Rate of Solar Panels
Solar panels have a degradation rate, and their power generation gradually decreases over 10 years and 20 years.
After 30 years, some may have a 40% decrease in power generation, while others may only decrease by about 10%.
By not deciding solely based on initial power generation and considering the degradation rate, you can choose solar panels without regrets!
Choosing Method 3: Compare Based on 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 provide a 10-year warranty, so it varies widely!
A longer warranty is always better, so let’s check the warranties of the manufacturers you are considering!
