Reasons why Kakeru Koumuten is chosen for solar panel installations in Miura City, Kanagawa Prefecture

One reason our company is entrusted with solar panel installations by customers in Miura City is that we“have a base in Kanagawa Prefecture”,
but we also have“strengths in solar panel installation that cannot be imitated by other companies”
, which has received high praise from many customers.

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

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 specialized contractors have knowledge about solar panels, it is a reality that many lack knowledge regarding the installation areas such as roofs and waterproofing.
For peace of mind and to avoid maintenance issues or troubles after construction, 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. Equipment specialized for 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 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, allowing us to set up scaffolding in-house.
By performing 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, we canprocure materials at a lower cost!
Additionally, we always have a stock of roofing materials, allowing us torespond 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 these materials all at once, but by sorting and recycling the waste, significant cost reductions can be achieved in waste disposal fees.

Exterior Renovation Dedicated Showroom

In our showroom, not only can you have meetings, but you can also
You can 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 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, giving us confidence in our construction techniques.
We are capable of handling large-scale roofing projects, such as those for factories!

How to Choose a Solar Panel Installation Contractor in Miura City, Kanagawa Prefecture

There are many solar panel installation contractors available in Miura City, 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.

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.

Confirm the presence of warranties and after-sales maintenance

When choosing a solar installation contractor, 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 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 unseen areas, you may not notice them yourself.
By conducting inspections during after-sales maintenance, you can detect issues 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 come 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 solar panel installation, be sure to obtain estimates from multiple contractors.

Even if the same manufacturer is used for 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 cost, it is essential to obtain estimates from multiple companies.

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 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 Systems

The benefits of introducing solar panels are summarized in the five points below!

Benefit 1: Economic Benefits

The biggest advantage of introducing 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 subsidy applications can be made!
Reducing the actual burden amount through subsidies is a significant advantage!

Benefit 3: Environmentally friendly!

Solar power generation contributes to the reduction of greenhouse gas emissions and decreases reliance on fossil fuels, 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 generating electricity.

Advantage 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 shielding benefits!

Advantage 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 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 considering 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 drilled in the roof to secure solar panels.
Drilling holes inevitably introduces the risk of leaks.
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.
It is not as simple as saying “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 the 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 panel and a 400W panel may seem at first glance that the higher output panel is better.
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 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 years and 20 years.
After 30 years, some may see 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 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.
Regarding output warranties, 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!
