Reasons Why Kakeru Koumuten is Chosen for Solar Panel Installations in Edogawa-ku, Tokyo

Regarding why we are entrusted with solar panel installations by customers in Edogawa-ku, Tokyo,
“Our unique strengths in solar panel installation that cannot be imitated by other companies”
have received high praise from many customers.

Because we are confident, we welcome multiple estimates!

1. We 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, many lack knowledge regarding the roof and waterproofing at the installation site, which is a reality…
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

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, allowing us to set up scaffolding ourselves.
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, 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

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 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 costs associated with the installation of 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 will handle 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, 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!

We will respond according to your preferences.

7. Human Resource Development

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 Edogawa-ku, Tokyo

There are many solar panel installation contractors available in Edogawa-ku, Tokyo, and it can be confusing to choose the right one.

Therefore, when requesting solar panel installation contractors or storage battery installation work, let’s check the following 4 points.

By confirming the above 4 points, you will be able to choose a reliable contractor.

Which Solar Power Installation Company is Best? Introducing How to Choose Without Regret!When considering the introduction of solar power generation, the mos...

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 roofing and waterproofing at the installation site is also crucial.

Check for warranties and after-sales maintenance

When choosing a solar installation contractor, make sure to check for warranties.

While the 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 in case of leaks 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 may not be visible, you might 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 offer after-sales maintenance and send out annual DM!
Please check the DM, and if you wish, we will visit for after-sales maintenance!

Warranty and Payment翔工務店の屋根工事、外壁塗装工事、シーリング工事の保証など簡単にご説明させて頂いております！！ 弊社では前金、中間金は頂いておりません！！...

Obtain estimates from multiple contractors (at least 3 companies)

When requesting the installation of solar panels, obtain estimates from multiple contractors.

Even for the same manufacturer and the same construction details, 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 cost, it is essential to obtain estimates from multiple contractors.

When comparing estimates, please ensure to 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 construction and proceed with the work only 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, the rise in electricity costs allows you to gain benefits by consuming the electricity you generate!
Electricity costs are expected to continue rising, 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 the reduction of carbon dioxide emissions and decreases dependence on fossil fuels, helping to mitigate global warming.
It is considered an environmentally friendly method of power generation because 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 Use Possible Even During Power Outages!!

By installing a storage battery, you can use electricity even during emergencies like power outages!

What are the Benefits of Installing Solar Panels? An Explanation of the Surprisingly Unknown Disadvantages!In recent years, due to rising electricity costs, increased environm...

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 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 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.

Dedicated Catch Base Hardware for Horizontal Metal Roofs

Note 3: The Roof Will Become Heavier

Installing solar panels will add weight to the roof. For 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 simply a matter of “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 vary in size and generation capacity depending on the manufacturer.
For example, 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 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 output, 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 on!

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!
