Reasons Why Kakeru Koumuten is Chosen for Solar Panel Installations in Mitaka, Tokyo
Regarding why we are entrusted with solar panel installations by customers in Mitaka, Tokyo,
“Our strengths in solar panel installation that cannot be matched 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, so we welcome estimates from any number of companies!
1. We can also handle exterior renovations other than solar panel installations!

Most issues 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, 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 issues after solar panel installation!
2.Facilities specialized in exterior renovations
Kakeru Koumuten Co., Ltd. has prepared the following warehouses and material storage areas to provide low-cost, high-quality solar and exterior renovation services.
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 set up scaffolding in-house.
By conducting scaffolding work with our own scaffolding team instead of outsourcing, we can also cut costs related to 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 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 at once, 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 earnings and installation costs when introducing solar panels!

How to Choose a Solar Panel Installation Contractor in Mitaka, Tokyo
There are many solar panel installation contractors available in Mitaka, 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 four points.
● 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 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 due to 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 treatment due to misjudgment of the type of waterproofing, resulting in leaks..
and so on.
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 of leaks 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 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 visit you for aftercare services!
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 for the same type of work, costs, warranties, and after-sales services may vary.
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 companies.
When comparing estimates, please check carefully the following:
“Check the 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 the construction and proceed with the work after it has been accepted!
The flow will be that the subsidy will be decided and granted after the construction is completed!
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, 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 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 produces no 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 insulation benefits!
Benefit 5: Electricity Available 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!
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 a roof renovation 10 to 20 years later, there will be costs for 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 as part of the preliminary stage of 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.
This inevitably increases the 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.
Special Catch 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’s 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 the more power generated, the better!
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 like 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,” leading to different installation capacities on the same roof due to the size difference.
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%.
By not deciding solely based on initial power generation and considering the degradation rate, you can avoid regrets with 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 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!
