Reasons why Kakeru Koumuten is chosen for solar panel installations in Inagi City, Tokyo
Regarding why customers in Inagi City, Tokyo, entrust us with solar panel installations,
“Our strengths in solar panel installation that cannot be imitated by other companies”
have received high praise from many customers.
so we would appreciate it if you could compare our estimates with those of other companies.
We are confident, and 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 solar panels, many lack expertise regarding the roof and waterproofing at the installation site.
For peace of mind and to avoid maintenance issues or troubles after installation, it is better to have someone knowledgeable about roofs!
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 issues after solar panel installation!
2.Equipment specialized for exterior renovations
At Kakeru Koumuten Co., Ltd., we have prepared the following warehouses and material storage areas to provide solar construction 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, allowing us to assemble the scaffolding ourselves.
By performing the scaffolding work with our own scaffolding team instead of outsourcing, we can also reduce the 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, you can purchase materials at a lower cost!
Additionally, we always have a stock of roofing materials, allowing us to respond quickly even in emergencies!
In-house sorting and transportation of waste materials
When installing solar panels, roofing work is often involved, generating various types of waste materials such as paint, wood, and metal.
Most contractors dispose of these materials all together, but by sorting and recycling the waste, significant cost savings 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 revenue 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 explain the structure, allowing us to provide detailed explanations!

How to Choose a Solar Panel Installation Contractor in Inagi City, Tokyo
There are many solar panel installation contractors available in Inagi City, Tokyo, and you may be unsure which one to choose.
Therefore, when requesting solar panel installation contractors or storage battery installation work, let’s 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 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.
Knowledge of roofing, not just 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 due to contractor’s lack of knowledge
・Solar panels installed on a deteriorated roof causing leaks,
・Solar panels installed on a roof with a short lifespan, requiring renovations to detach and reattach the panels within a few years,
・Misjudging the type of waterproofing and applying incorrect treatment, leading to leaks,
and more.
When installing solar panels, understanding the condition and type of the existing roof allows you to avoid unnecessary expenses and unforeseen 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 leaks occur after installation!
If the contractor has a warranty period, they will respond free of charge in case 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 can be in hidden areas, you may 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 visit you for 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 with the same manufacturer and 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 desired repair contractor at a lower price, 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 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 decided and granted!
Benefits of Introducing Solar Power Equipment
The benefits of installing solar panels are as follows!
Benefit 1: Economic Benefits
The biggest advantage of installing solar panels is the economic benefit!
Although the selling price of electricity has decreased compared to ten years ago, due to rising electricity costs, you can benefit by 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 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, thus helping to mitigate global warming.
Since there is no noise or harmful substance emissions during the power generation process, it is considered an environmentally friendly method of power generation.
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 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 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 be able to request 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 require holes to be drilled in the roof to secure solar panels.
As a result, there is an unavoidable risk of leaks due to the holes.
Of course, we will ensure proper waterproofing, but if you are concerned about drilling holes, one option is to replace the roofing material with a metal roof and secure the solar panels using the catch method.
Dedicated Catch Base Hardware for Horizontal Metal Roofs
Note 3: The Roof Will Become Heavier
With the installation of solar panels, the roof will become heavier. For tile roofs, it may be reassuring to replace them with a lighter roofing material.
How to Choose Solar Panels?
There are many manufacturers of solar panels, and their output (power generation) and costs vary.
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 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.
A 350W panel and a 400W panel may seem that the higher output panel is better at first glance.
However, if the size of the panels does not fit well on 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.
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 experience 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 regarding your solar panels!
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 the output warranty, some manufacturers offer a 30-year warranty while others provide a 10-year warranty, so it varies widely!
Since a longer warranty is always better, let’s check the warranties of the manufacturers you are considering!
