this information will surely be helpful, so please take a look!
Reasons why Kakeru Koumuten is chosen for solar panel installations in Tsurumi-ku, Yokohama
One reason why our company is entrusted with solar panel installations by customers in Tsurumi-ku, Yokohama is
that “Kakeru Koumuten is located in Yokohama”,
but we also have “strengths in solar panel installation that other companies cannot replicate”
which have received high praise from many customers.
We have absolute confidence in the “cost,” “quality,” “plan” for
the solar panel installation work in Tsurumi-ku, so we would be grateful if you could compare our estimates with those of other companies.
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 water 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, 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 issues and 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 us to respond quickly to maintenance and urgent troubles after solar panel installation!
2. Equipment specialized in 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 ourselves.
By performing 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 canprocure materials at a lower cost!
Additionally, we always have a stock of roofing materials, enabling us torespond quickly in emergencies!
In-house sorting and transportation of waste materials
The installation of solar panels often involves roofing work, generating various types of waste materials such as paint, wood, and metal.
While most contractors dispose of these materials together, separating and recycling waste can lead to significant cost reductions in waste disposal fees.
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 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 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 ensured.
We can provide consistent in-house construction services 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 roofing projects, such as those for factories!
5. Warranty and Aftercare

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 roofing and waterproofing at the installation site is also crucial.
⚠︎Examples of troubles due to contractor’s lack of knowledge
・Solar panels installed on a deteriorated roof causing leaks,
・Solar panels installed on a roof with a short lifespan, requiring a renovation to detach and reattach the panels within a few years,
・Misjudging the type of waterproofing and applying incorrect treatment, 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.
Check for warranties and after-sales maintenance
When choosing a solar installation contractor, make sure to check for warranties.
While the 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 address any leaks that occur after installation at no cost.
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 may not be visible, you might not notice them yourself.
By conducting inspections during after-sales maintenance, you can detect abnormalities 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 offer after-sales maintenance and send out annual DM notifications!
Please check the DM, and if you wish, we will visit you 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 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 companies.
When comparing estimates, please check carefully:
“Verification of estimate items”
“Types of solar panels”
“Warranties and after-sales service”
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 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 consuming the electricity you generate!
Electricity prices are expected to continue to rise, 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: 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 due to subsidies is a significant advantage!
Benefit 3: Environmentally Friendly!
Solar power generation contributes to the reduction of carbon dioxide emissions and decreases dependence 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.
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 insulation benefits!
Benefit 5 Electricity can be used even during power outages!!
By installing a storage battery, you can use electricity even during emergencies like 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 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 that considers maintenance costs before introducing solar panels!
Point 2: The Risk of Water Leakage 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, there is an unavoidable 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.
Special Catch Base Hardware for Horizontal Metal Roofs
Note 3: The Roof Will Become 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.
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!
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 vary in size and power generation depending on the manufacturer.
For example, a 350W output panel and a 400W output panel may seem that the higher output panel is better at first glance.
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 numbers of panels that can be installed on the same roof due to size differences.
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%.
By not deciding solely based on initial power generation and considering the degradation rate, you can choose solar panels without regrets!
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 the output warranty, some manufacturers offer a 30-year warranty while others provide a 10-year warranty, so it can be quite varied!
A longer warranty is always better, so be sure to check the warranties of the manufacturers you are considering!
