Reasons Why Kakeru Koumuten is Chosen for Solar Panel Installations in Arakawa-ku, Tokyo
The reasons why we are entrusted with solar panel installations by customers in Arakawa-ku, Tokyo,
include our unique strengths in solar panel installation that cannot be imitated by other companies,
which 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 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 regarding the roof and waterproofing at the installation site.
For peace of mind and to avoid maintenance issues or 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.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 construction and exterior renovations.
We have established five bases centered around Yokohama City, Kanagawa Prefecture for our material storage and showroom.
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 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, 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
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 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 illustrate 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 installation 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, and we are confident in our construction techniques.
We are capable of handling large-scale roofing projects such as factories!
5. Warranty and Aftercare

How to Choose a Solar Panel Installation Contractor in Arakawa-ku, Tokyo
There are many solar panel installation contractors available in Arakawa-ku, Tokyo, and it can be confusing to decide which one to choose.
Therefore,when requesting solar panel installation 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 the presence of warranties and after-sales maintenance
● Obtain estimates from multiple contractors (at least 3 companies)
● Confirm whether 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 deteriorated roof, leading to leaks..
・Solar panels were 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 led to incorrect treatment and subsequent leaks..
and so on.
When installing solar panels, understanding the condition and type of the existing roof allows you to avoid unnecessary expenses and unexpected troubles.
Check for warranties and after-sales maintenance
When choosing a solar installation contractor, make sure to check for warranties.
While solar panels and storage 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 if leaks occur after installation.
Additionally, some contractors offer after-sales services separate from warranties, so be sure to check if the contractor you are considering has after-sales service.
Since abnormalities or damage on the roof can be in hidden areas, you may not notice them yourself.
By conducting inspections during after-sales maintenance, you can detect abnormalities 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 after-sales maintenance and send out annual DM!
Please check the DM, and if you wish, we will visit you for after-sales maintenance!
Obtain estimates from multiple contractors (at least 3 companies)
When requesting solar panel installation, obtain estimates from multiple contractors.
Even for the same manufacturer and the same construction content, costs and warranties or after-sales services may vary.
Additionally, obtaining multiple estimates makes it easier to negotiate prices.
To request your preferred repair contractor at a lower price, it is essential to get estimates from multiple contractors.
When comparing estimates, please check the following:
“Verification of estimate items”
“Types of solar panels”
“Warranties and after-sales service”
Make sure to compare these details carefully! 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 summarized in the five points below!
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 costs 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: Subsidies can be utilized!
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 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 generation 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 can be used even during power outages!!
By installing a storage battery, it becomes possible to use electricity even during emergencies like 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 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 considers 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 these 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 (generation capacity) 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 generation capacity of the roof
When installing solar panels on the roof, it is important to consider how much electricity can be generated in the limited area, and the more electricity generated, the better!
Solar panels come in various sizes depending on the manufacturer, and their generation capacities differ.
For example, a 350W output panel and a 400W output panel may seem at first glance that the higher output panel is better.
However, if the size of the panel 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 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 rate of solar panels
Solar panels have a degradation rate, 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%.
Choosing based solely on initial generation capacity 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 can differ greatly!
Since longer warranties are generally better, be sure to check the warranties of the manufacturers you are considering!
