Reasons Why Kakeru Koumuten is Chosen for Solar Panel Installation in Hayama, Miura-gun, Kanagawa Prefecture
One reason our company is entrusted with solar panel installation by customers in Miura-gun, Hayama is that
we have a base within Kanagawa Prefecture,
but we also have “strengths in solar panel installation that cannot be imitated by other companies”, which has earned us high praise from many customers.
the solar panel installation work in Hayama, Miura-gun, so we would be grateful if you could compare it with estimates from other companies.
Because we are confident, we welcome estimates from any number of companies!
1. We can 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 specialized contractors for solar panel installation have knowledge about solar panels, many lack knowledge regarding the roof and waterproofing at the installation site, which is a reality…
It’s safer to have someone knowledgeable about roofs to avoid maintenance and trouble after construction!
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. Specialized equipment for exterior renovations
At Kakeru Koumuten Co., Ltd., we have prepared the following warehouses and material storage areas to provide solar construction 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 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 potential earnings and installation costs if you decide to introduce 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., allowing for high-quality roof renovations at reduced costs.
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 ensured.
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 and painting specialists on staff, giving us confidence in our construction techniques.
We are capable of handling large-scale roof projects, such as those for factories!

6. Flexible and Prompt Response
Our company is equipped to handle various roofing troubles and situations.
If you are unable to access the roof due to height, we can utilize a drone to assist!
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 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 varies 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 Hayama, Miura-gun, Kanagawa Prefecture
There are many solar panel installation contractors available in Hayama, Miura-gun, 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.
● They should have extensive knowledge not only about solar panels but also about roofs.
● Confirm the presence of warranties and aftercare services
● Obtain estimates from multiple contractors (at least 3 companies)
● Check if 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 the contractor’s lack of knowledge.
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 severely 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 more
When installing solar panels, understanding the condition and type of the existing roof allows you to avoid unnecessary expenses and unexpected troubles.
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 respond free of charge in the event of leaks after installation.
Additionally, some contractors provide aftercare services separately 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 failures!
Kakeru Koumuten Co., Ltd. provides a leak warranty as part of the construction warranty for solar panel installations.
We also offer aftercare services and send out annual DM notifications!
Please check the DM, and if you wish, we will visit you for aftercare services!
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 for 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 preferred repair contractor at a lower cost, it is essential to obtain estimates from several contractors.
When comparing estimates,
“Check the items in the estimate”
“Type of solar panels”
“Warranties and after-sales services”
Let’s compare these details closely 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 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 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!
Although 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!
As electricity prices are expected to continue rising, the ability to cover your consumption with solar power is appealing!
If you plan to use the generated power 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 reduces carbon dioxide emissions and dependence on fossil fuels, contributing to the mitigation of 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.
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 shielding benefits!
Benefit 5: Electricity can be used even during power outages!
If you install a storage battery, you can 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 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 for 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 reassuring to consider maintenance costs in your 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 the solar panels.
As a result, there is an inherent 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.
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.
How to choose solar panels?
There are many manufacturers of solar panels, and their output (power generation) and costs vary widely.
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!
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 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.
If you compare a 350W panel with a 400W panel, at first glance, the panel with higher output may seem better.
However, if the panel sizes do not fit well on the roof, it may be the case that “20 panels of 350W can be installed” while “only 15 panels of 400W can be installed” 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 or 20 years.
After 30 years, some may see 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!
How to choose 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!
A longer warranty is always better, so be sure to check the warranties of the manufacturers you are considering!
