Reasons why Kakeru Koumuten is chosen for solar panel installations in Hachioji, Tokyo
Regarding why our company is entrusted with solar panel installations by customers in Hachioji, Tokyo,
“Our unique strengths in solar panel installation that cannot be imitated by other companies”
have received high praise from many customers.
We would greatly appreciate it if you could compare our estimates with those of other companies.
Because we are confident, we welcome estimates from as many companies as possible!
1. We also handle exterior renovations other than solar panel installation!

Most troubles such as leaks that occur during solar panel installation are due to the lack of knowledge of the solar panel installation contractors.
While specialized contractors have knowledge about solar panels, it is a reality that many lack knowledge regarding the roof and waterproofing at the installation site.
For peace of mind and to avoid maintenance issues and troubles after installation, it is safer to have expertise in roofing!
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. Equipment specialized 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 for material storage and showrooms.
In-house ownership of scaffolding materials


We own the scaffolding materials necessary for the installation of solar panels and can assemble the scaffolding ourselves.
By conducting scaffolding work with our own scaffolding team instead of outsourcing, we can also cut costs for scaffolding work. We have enough scaffolding materials for approximately 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!
In-house sorting and transportation of waste materials
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 together, separating and recycling waste can significantly cut down on disposal costs.
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 earnings and installation costs when introducing solar panels!
Since roofing and exterior wall work often accompany each other, we have samples of roofing materials and models that show the structure, allowing us to provide detailed explanations!
3.Complete In-House Construction
One of Kakeru Koumuten’s major strengths is 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 installation to exterior wall painting and roof renovations!
4. Various Permits Obtained & Skilled Workers on Staff


We have obtained construction industry permits as well as permits for industrial waste collection and transportation!
We also have nationally certified sheet metal and painting specialists on staff, and we are confident in our construction techniques. We can handle large-scale roof projects for factories and more!
5. Warranty and Aftercare
In addition to the manufacturer’s warranty for solar panel installation, we also provide our own leak warranty!
Aftercare is available annually, and we send out notification DM each year. If you have any 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.
If you cannot access the roof due to height, we can utilize a drone for assistance!
During 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 provide cleaning services with a specialized brush.
We will respond according to the customer’s wishes.
7. Human Resource Development
We create various roof models to enhance skills and conduct 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 Hachioji, Tokyo
There are many solar panel installation contractors available in Hachioji, Tokyo, and you may be unsure which one to choose.
Therefore,when requesting solar panel installation or storage battery installation work, make sure to check the following 4 points.
● They should have extensive knowledge not only about solar panels but also about roofs.
● Confirm the presence of warranties and after-sales maintenance
● 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.
Knowledge of roofing in addition to solar panels
Many causes of poor installation of solar panels stem from a lack of knowledge on the part of the contractor.
While knowledge about solar panels is certainly important, understanding the roof and waterproofing at the installation site is also crucial.
⚠︎Examples of troubles caused by contractor’s lack of knowledge
・Solar panels were installed on a severely deteriorated roof, leading to leaks..
・Solar panels were installed on a roof with a short lifespan, necessitating a costly removal and reinstallation within a few years..
・Incorrect waterproofing treatment was applied due to misjudgment of the type, resulting in 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 after-sales maintenance
When choosing a solar installation contractor, make sure to check for warranties.
While the solar panels and batteries come with manufacturer warranties, also confirm whether there is a construction warranty in case leaks occur after installation!
If the contractor offers a warranty period, they will address any leaks that occur after installation free of charge.
Additionally, some contractors provide after-sales services separate from warranties, so be sure to check if the contractor you are considering has after-sales services.
Since abnormalities or damages on the roof may not be visible, you might not notice them yourself.
By conducting inspections during after-sales maintenance, you can detect issues early and prevent major repairs or failures!
Kakeru Koumuten Co., Ltd. offers a leak warranty as part of the construction guarantee for solar panel installations.
We also provide after-sales maintenance and send out annual DM!
Please check the DM, and if you wish, we will come to perform after-sales maintenance!
Obtain estimates from multiple contractors (at least 3 companies)
When requesting the installation of solar panels, be sure to obtain estimates from multiple contractors.
Even if the same manufacturer is used and the same construction work is performed, costs may vary, as well as warranties and after-sales services.
Additionally, obtaining multiple estimates makes it easier to negotiate prices.
To request your desired repair contractor at a lower price, it is essential to obtain estimates from multiple contractors.
When comparing estimates, please check carefully the following:
“Verification of estimate items”
“Type of solar panels”
“Warranties and after-sales services”
Make sure to compare these details closely! If the rank of auxiliary materials is low or if processes 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 the construction starts and proceed with the work 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 introducing solar panels are as follows!
Benefit 1: Economic Benefits
The biggest benefit of introducing solar panels is the economic advantage!
Although the selling price of electricity has decreased compared to ten years ago, rising electricity costs allow you to gain benefits by consuming the electricity you generate!
Electricity prices are expected to continue to rise, making it attractive to cover your consumption with solar power generation!
If you plan to use the generated electricity at night, installing a storage battery is essential!
Benefit 2: You can utilize subsidies!
Subsidy conditions and amounts vary by prefecture and municipality, but there is a high probability that you can apply for subsidies!
Reducing the actual burden amount through subsidies is a significant advantage!
Benefit 3 Environmentally Friendly!
Solar power generation contributes to the reduction of carbon dioxide emissions and decreases reliance on fossil fuels, helping to mitigate global warming.
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 performance is enhanced.
Especially in summer, it can effectively block direct sunlight, providing significant heat insulation 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 be noted when introducing solar power generation?
Next, we will explain the “three points to note” when installing solar panels!
Point 1: Maintenance costs may be incurred
The maintenance costs are related more to the roof where the solar panels are installed rather than the solar panels themselves.
If you perform roof renovations 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 ask for a simulation that considers maintenance costs before introducing solar panels!
Point 2: The risk of leaks may increase depending on the roofing material
Slate roofs and tile roofs inevitably require holes to be made in the roof to secure solar panels.
This creates a risk of leaks due to the holes made in the roof.
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.
Catch-type base brackets for horizontal metal roofs
Note 3: The roof will become heavier
As solar panels are added, the roof will become heavier. In the case of tile roofs, it may be reassuring to replace them with lighter roofing materials.
How to Choose Solar Panels?
There are many manufacturers of solar panels, and their output (generation capacity) and costs vary widely.
It is not accurate to say “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 generation capacity of the roof
When installing solar panels on the roof, it is important to consider how much power can be generated in the limited area, and the more power generated, the better!
Solar panels come in various sizes depending on the manufacturer, and their generation capacities differ.
For example, a 350W panel and a 400W panel may seem like the higher output panel is better at first glance.
However, if the size of the panels does not fit well on the roof, “20 panels of 350W can be installed, while only 15 panels of 400W can be installed,” leading to different installation capacities on the same roof due to the size difference.
400W × 15 panels = 6kW (total generation capacity of the roof)
350W × 20 panels = 7kW (total generation capacity 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 rates of solar panels
Solar panels have degradation rates, and their generation capacity gradually decreases over 10 or 20 years.
After 30 years, some may see a 40% decrease in generation capacity, while others may only decrease by about 10%.
By considering the degradation rate along with the initial generation capacity, 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.
For output warranties, some manufacturers offer a 30-year warranty, while others provide a 10-year warranty, so it can differ widely!
Since a longer warranty is always better, let’s check the warranties of the manufacturers you are considering!
