Reasons why Kakeru Koumuten is chosen for solar panel installation in Ashigarakami-gun (Hakone, Manazuru, Yugawara)

One reason our customers in Ashigarakami-gun trust us with solar panel installation is that we have“a base within Kanagawa Prefecture”,
but we also have“unique strengths in solar panel installation that other companies cannot replicate”
, which has earned us high praise from many customers.

Since we are confident, we welcome estimates from any number of companies!

1. We also handle exterior renovations other than solar panel installation!

 
Most issues such as leaks that occur during solar panel installation are due to the lack of knowledge of the solar panel installation contractors.
While specialists 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 and trouble after construction, it is safer 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 work and exterior renovations at low cost and high quality.
We have established five bases centered around Yokohama City, Kanagawa Prefecture for material storage and showrooms.

In-house ownership of scaffolding materials

We own the scaffolding materials necessary for the installation of solar panels and can assemble the scaffolding ourselves.
By conducting the scaffolding work with our own scaffolding team instead of outsourcing, we can also cut costs on 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

When installing solar panels, roofing work is often involved, resulting in various types of waste materials such as paint, wood, and metal.
Most contractors dispose of everything together, but by sorting and recycling the waste materials, 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 roofing materials!
We can also provide simulations for the potential earnings 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 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 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 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 every year.
If you have any questions about the warranty, please click on the image above!

How to Choose a Solar Panel Installation Contractor in Ashigarakami District, Kanagawa Prefecture (Hakone Town, Manazuru Town, Yugawara Town)

There are many solar panel installation contractors available in Ashigarakami District (Hakone Town, Manazuru Town, Yugawara Town), and it can be confusing to choose the right one.

Therefore,when requesting solar panel installation or storage battery installation work, let’s confirm 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 about roofs as well as 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.

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 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 installation guarantee for solar panels.
We also offer aftercare services and send out annual DM notifications!
Please check the DM, and if you wish, we will come to provide aftercare services!

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, be sure to obtain estimates from multiple contractors. Even with the same manufacturer and the same construction details, costs may vary, and 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 price, it is essential to get estimates from several companies.

When comparing estimates,

“Check the items in the estimate”
“Type of solar panels”
“Warranties and after-sales services”

Let’s carefully compare these details to make a decision! Avoid judging solely based on cost, as using lower-quality materials or skipping processes can reduce expenses!

Confirm whether 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 funding 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.
Be sure to apply for the subsidy before starting 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 Advantage

The biggest advantage of installing solar panels is the economic benefit!
The selling price of electricity has decreased compared to ten years ago, but due to rising electricity costs, you can benefit by consuming the electricity 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 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 reduces carbon dioxide emissions and dependence on fossil fuels, contributing to the mitigation of global warming.
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 performance is improved.
Especially in summer, it can effectively block direct sunlight, providing significant heat insulation benefits!

Merit 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 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

Maintenance costs refer 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 consider maintenance costs in advance and request a simulation before introducing solar panels!

Point 2: The risk of leaks increases depending on the roofing material

For slate roofs and tile roofs, it is necessary to make holes in the roof to secure solar panels.
As a result, there is inevitably a risk of leaks due to the holes made in the roof.
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-type base hardware for horizontal metal roofs

Point 3: The roof becomes heavier

With the installation 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.

13 Common Troubles with Solar Power Installation! Introducing Solutions and Preventive Measures!By installing solar power generation at home, you can expect various...

How to choose solar panels?

There are many manufacturers of solar panels, and the output (power generation) and costs vary widely.
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!

How to choose 1: Compare based on the 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.
For example, a 350W output panel and a 400W output panel may seem that the panel with higher output 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!

How to choose 2: Compare based on the 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 have a 40% decrease in power generation, while others may only decrease by about 10%.
By considering the degradation rate along with the initial power generation, you can avoid regrets when choosing solar panels!

How to choose 3: Compare based on warranty period

The warranty for solar panels includes various types such as “output warranty,” “natural disaster warranty,” and “system warranty,” and the warranty periods differ by manufacturer.
Regarding the output warranty, some manufacturers offer a 30-year warranty, while others provide a 10-year warranty, so it varies widely!
A longer warranty is always better, so let’s check the warranties of the manufacturers you are considering!
