Reasons Why Kakeru Koumuten is Chosen for Solar Panel Installations in Minamiashigara City, Kanagawa Prefecture
One reason our company is entrusted with solar panel installations by customers in Minamiashigara City is that we “have a base within Kanagawa Prefecture.”
Additionally, we have “unique strengths in solar panel installation that cannot be imitated by other companies,”
which has earned us high praise from many customers.
We would be grateful if you could compare our estimates with those of other companies.
Because we are confident, we welcome estimates from as many companies as possible!
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 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 is reassuring to have someone knowledgeable about roofs to avoid maintenance and troubles 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 troubles 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 work and exterior renovations at low cost and high quality.

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 conducting 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, 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
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 when introducing solar panels!
Since roofing work and exterior wall work often go hand in hand, we 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 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!

6. Flexible and Prompt Response
Our company is equipped to handle various roofing troubles and situations.
Even when unable to access the roof at high altitudes, we can respond using a drone!
During rain leak investigations, we can also conduct inspections using a thermal imaging camera.
If the power generation of the solar panels decreases due to dirt, we can also perform cleaning with a specialized brush.
We will respond according to the customer’s wishes.
7. Human Resource Development
To enhance our skills, we create various roof models and conduct practical training.
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 scenarios.

How to Choose a Solar Panel Installation Contractor in Minamiashigara City, Kanagawa Prefecture
There are many solar panel installation contractors available in Minamiashigara City, 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.
● Not only knowledgeable about solar panels but also have extensive knowledge about roofs
● Confirm whether there is a warranty and aftercare maintenance
● 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 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 roofing and waterproofing at the installation site is also crucial.
⚠︎Examples of troubles due to lack of contractor knowledge
・Solar panels were installed on a deteriorated roof, leading to leaks..
・Solar panels were installed on a roof with a short lifespan, necessitating a renovation to remove and reattach the panels within a few years..
・Incorrect waterproofing treatment was applied due to misjudgment of the type, resulting in 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 whether there is a warranty and aftercare maintenance
When choosing a solar installation contractor, make sure to check for warranty availability.
While solar panels and batteries come with a manufacturer’s warranty, 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 aftercare services separate from the warranty, 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 maintenance, you can detect issues early and prevent major repairs or breakdowns!
Kakeru Koumuten Co., Ltd. provides a leak warranty as part of the construction warranty for solar panel installations.
We also conduct aftercare maintenance and send out annual DM notifications!
Please check the DM, and if you wish, we will visit for aftercare maintenance!
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 construction details are the same and from the same manufacturer, costs, 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 multiple contractors.
When comparing estimates, please check carefully:
“Check the estimate items”
“Type of solar panels”
“Warranties and after-sales services”
Make sure to compare these details closely! If the rank of the auxiliary materials is low or if steps are skipped, costs can be reduced, so avoid judging solely based 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 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, due to rising electricity costs, you can gain benefits by consuming the electricity you generate!
Electricity costs are expected to continue to rise, making it attractive to cover your consumption with solar power generation!
If you plan to use the generated electricity at night, the installation of 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 leads to a reduction in carbon dioxide emissions and decreases 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 properties are enhanced.
Especially in summer, it can effectively block direct sunlight, leading to significant heat insulation benefits!
Benefit 5 Electricity can be used even during power outages!!
By installing a storage battery, you can use electricity even during power outages!
What Points Should You Be Careful About When Introducing Solar Power?
Next, we will explain the “three points to be careful about” 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 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 ask for 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 made in the roof to secure solar panels.
As a result of making holes in the roof, there is inevitably a 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.
Catch-type base brackets for horizontal metal roofs
Note 3: The roof will become heavier
Since solar panels will be installed, 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”, and 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 by 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 like the higher output panel is better at first glance.
However, if the size of the panel 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!
Choosing Method 2: Compare by 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 choose solar panels without regrets!
Choosing Method 3: Compare by 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 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!
