Reasons why Kakeru Koumuten is chosen for solar panel installations in Aoba-ku, Yokohama

One reason why we are entrusted with solar panel installations by customers in Aoba-ku, Yokohama is
that “Kakeru Koumuten is located in Yokohama,” but
“Our unique strengths in solar panel installation that cannot be imitated by other companies”
have also 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 specialists 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 construction, it is better 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 for quick responses to maintenance and urgent troubles 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, allowing us to assemble the 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 procure 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 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 potential earnings and installation costs when introducing solar panels!

Since roofing and exterior wall work often accompany each other, we also have samples of roofing materials and models that explain 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 permits for construction work and 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 each year.

During rain leak investigations, we can also conduct surveys using a thermal imaging camera.

If the power generation of the solar panels decreases due to dirt, we can also provide cleaning with a specialized brush.
We will respond according to your preferences.

7. Human Resource Development

We create various roof models to enhance skills and conduct practical training.
Since the construction method changes 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 Aoba-ku, Yokohama

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

Therefore, when requesting solar panel installation contractors 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.

Check for warranties and after-sales maintenance

When choosing a solar installation contractor, be 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 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 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 visit 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 obtain estimates from multiple companies.

When comparing estimates,

“Check the items in the estimate”
“Types of solar panels”
“Warranties and after-sales service”

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

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 of not receiving them 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 provided!

Benefits of Introducing Solar Power Equipment

The benefits of installing solar panels are as follows!

Benefit 1: Economic Advantage

The biggest advantage of installing solar panels is the economic benefit!
While the selling price of electricity has decreased compared to ten years ago, rising electricity costs allow you to benefit from self-consumption of the generated power!
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: 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!

The reduction in actual burden due to subsidies is a significant advantage!

Benefit 3: Environmentally Friendly!

Solar power generation contributes to mitigating global warming as it reduces carbon dioxide emissions and dependence on fossil fuels.
It is considered an environmentally friendly power generation method since there is no noise or harmful substance emissions 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 shielding 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 such as power outages!

What are the points to be aware of when introducing solar power generation?

Next, we will explain the “three points to be aware of” when installing solar panels!

Point 1: Maintenance costs may be incurred

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

Point 2: The risk of leaks may increase 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.

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 accurate to say “this manufacturer has the best solar panels”; 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 roof power generation

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 power generation 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 panel size 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 size differences.

400W × 15 panels = 6kW (total roof power generation)
350W × 20 panels = 7kW (total roof power generation)
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 rates of solar panels

Solar panels have degradation rates, and their power generation gradually decreases over 10 or 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 choose solar panels without regrets!

Choosing Method 3: Compare based on warranty periods

Solar panels come with various types of warranties, including “output warranty,” “natural disaster warranty,” and “system warranty,” and the warranty periods vary by manufacturer. Some manufacturers offer a 30-year output warranty, while others may only offer a 10-year warranty, so it varies! The longer the warranty, the better, so be sure to check the warranties of the manufacturers you are considering!
