Reasons Why Kakeru Koumuten is Chosen for Solar Panel Installation in Aoba-ku, Yokohama
Regarding why we are entrusted with solar panel installation by customers in Aoba-ku, Yokohama,
“Our Strengths in Solar Panel Installation That Other Companies Cannot Imitate”
have received high praise from many customers.
so we would be grateful if you could compare our estimates with those of other companies.
We are confident, so we welcome estimates from any number of companies!
1. We can 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 contractors specializing in solar panel installation have knowledge about solar panels, many lack expertise regarding the roof and waterproofing at the installation site.
For peace of mind and to avoid maintenance issues and troubles after installation, it is safer to have someone knowledgeable about roofs!
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 low-cost, high-quality solar construction and exterior renovations.
We have established five bases centered around 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 conducting the 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 all together, significant cost savings on waste disposal can be achieved by sorting and recycling the waste materials.
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 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 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 Acquired & 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 Midori-ku, Sagamihara
There are many solar panel installation contractors available in Midori-ku, Sagamihara, and it can be confusing to decide which one to choose.
Therefore,when requesting solar panel installation or storage battery installation work, let’s check the following 4 points.
● Have extensive knowledge not only about solar panels but also about roofs
● Confirm the existence of warranties and after-sales maintenance
● Obtain estimates from multiple contractors (at least 3 companies)
● Confirm whether 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 contractor’s lack of knowledge
・Solar panels installed on a deteriorated roof leading to leaks,
・Solar panels 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 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, be 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 has a warranty period, they will respond free of charge in the event 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 damages on the roof can be in hidden areas, you may 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 guarantee for solar panel installations.
We also conduct after-sales maintenance and send out DM every year!
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 details, 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 contractors.
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 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!
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 costs are expected to continue to rise, 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!
The conditions and amounts of subsidies 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 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 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 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 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 associated with 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 comforting to consider maintenance costs in advance and request a simulation 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, there is an inherent 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 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 a lighter roofing material.
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 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!
The sizes of solar panels vary by manufacturer, and so does their power generation.
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 panels 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 roof power output)
350W × 20 panels = 7kW (total roof power output)
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 panels 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!
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.
For output warranties, some manufacturers offer a 30-year warranty while others provide a 10-year warranty, so it varies widely!
Since longer warranties are generally better, be sure to check the warranties of the manufacturers you are considering!
