Reasons Why Kakeru Koumuten is Chosen for Solar Panel Installation in Hamura, Tokyo
Regarding why we are entrusted with solar panel installation by customers in Hamura, Tokyo,
“Our strengths in solar panel installation that cannot be imitated by other companies”
have received high praise from many customers.
We would be grateful if you could compare our estimates with those of other companies.
We are confident, so we welcome estimates from any number of companies!
1. We also handle exterior renovations other than solar panel installations!

Most troubles such as leaks caused by solar panel installations are due to the lack of knowledge of the solar panel installation contractors.
While contractors specializing in solar panel installations have knowledge about the panels themselves, many lack understanding regarding the roof and waterproofing at the installation site.
For peace of mind and to avoid maintenance issues or troubles after installation, it’s better 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.Facilities specialized in exterior renovations
At Kakeru Koumuten Co., Ltd., we have prepared the following warehouses and material storage areas to provide low-cost, high-quality solar work and exterior renovations.
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, allowing us to assemble the scaffolding in-house.
By conducting scaffolding work with our own scaffolding team instead of outsourcing, we can also cut costs associated with scaffolding work.
We have 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.
Most contractors dispose of these materials all at once, but by sorting and recycling the waste, significant cost reductions on waste disposal can be achieved.
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 if you decide to introduce 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 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 will handle everything, including sales and construction management, smooth communication is ensured.
We can provide consistent in-house construction from temporary scaffolding installation to exterior wall painting and roof renovations!
4. Various Permits Acquired & 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 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 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.
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
To enhance our skills, we create various roof models 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 scenarios.

How to Choose a Solar Panel Installation Contractor in Hamura, Tokyo
There are many solar panel installation contractors available in Hamura, Tokyo, and it can be confusing to decide which one to choose.
Therefore, when requesting solar panel installation contractors or storage battery installation work, let’s check the following 4 points.
● Have extensive knowledge not only about solar panels but also about roofs
● Confirm whether there is a warranty and aftercare 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 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
・Solar panels were installed on a deteriorated roof, leading to leaks..
・Solar panels were installed on a roof with a short lifespan, necessitating renovations to remove and reinstall the panels within a few years..
・Incorrect treatment due to misjudging the type of waterproofing, 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 whether there is a warranty and aftercare maintenance
When choosing a solar installation contractor, make sure to check for warranty availability.
While 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 has 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 maintenance, you can detect issues early and prevent major repairs or failures!
Kakeru Koumuten Co., Ltd. provides a leak warranty as part of the construction warranty for solar panel installations.
We also conduct aftercare maintenance and send out annual DM notifications!
Please check the DM, and if you wish, we will come to provide aftercare maintenance!
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 is used and the same construction work is performed, costs, warranties, and after-sales services may differ.
Additionally, obtaining multiple estimates makes it easier to negotiate prices.
To request your desired repair contractor at a lower cost, it is essential to obtain estimates from multiple contractors.
When comparing estimates, please check carefully the following:
“Check the items in the estimate”
“Type of solar panels”
“Warranties and after-sales services”
Make sure to compare these details closely! If the quality of the sub-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 the construction and proceed with the work after it has been accepted!
After the construction, the flow will be that the subsidy will be approved and granted!
Benefits of Introducing Solar Power Equipment
The benefits of installing solar panels are summarized in the five points below!
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, rising electricity costs allow you to benefit from consuming the electricity you generate!
Electricity prices are expected to continue to rise, making it attractive to cover your consumption with solar power!
If you plan to use the generated electricity at night, installing a storage battery is essential!
Benefit 2: You can utilize subsidies!
The conditions and amounts of subsidies vary by prefecture and municipality, but there is a high probability that you can apply for subsidies!
Reducing the actual burden through subsidies is a significant advantage!
Benefit 3 Environmentally Friendly!
Solar power generation leads to a reduction in carbon dioxide emissions and decreases reliance on fossil fuels, contributing to the mitigation of global warming.
Since there is no noise or harmful substance emissions during the power generation process, it is considered an environmentally friendly method of generating electricity.
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, leading to significant heat insulation benefits!
Benefit 5 Electricity can be used even during power outages!!
By installing a storage battery, you can use electricity even during 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 Are 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 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 the solar panels!
It would be comforting to request a simulation considering maintenance costs before introducing solar panels!
Point 2: The Risk of Leaks Increases 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, there is an inherent risk of leaks due to the holes.
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 hardware for horizontal metal roofs
Note 3: The roof will become heavier
With the addition 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.
How to choose solar panels?
There are many manufacturers of solar panels, and their output (power generation) and costs vary.
There is no definitive answer to “which manufacturer has the best solar panels”, and 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 the limited area, and it is always better to generate more power!
The size of solar panels varies by manufacturer, and so does the power generation.
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 panels 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,” resulting in different numbers of panels that can be installed on the same roof due to size differences.
400W × 15 panels = 6kW (total power generation of the roof)
350W × 20 panels = 7kW (total power generation 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 or 20 years.
After 30 years, some may see a 40% decrease in power generation, while others may only decrease by about 10%.
Choosing based solely on initial power generation without considering the degradation rate will lead to regrets later!
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 varies widely!
Since longer warranties are generally better, be sure to check the warranties of the manufacturers you are considering!
