Reasons Why Kakeru Koumuten is Chosen for Solar Panel Installations in Zama City, Kanagawa Prefecture
One reason our company is entrusted with solar panel installations by customers in Zama City is that
“we have a base within Kanagawa Prefecture.” However,
“Our unique strengths in solar panel installation that cannot be imitated by other companies”
have also garnered us much praise from many customers.
the solar panel installation work in Zama City, 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 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 have knowledge about solar panels, many lack expertise regarding the installation areas, such as roofs and waterproofing, which is a reality.
It is 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 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 and can 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 enough 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
The installation of solar panels often involves roofing work, 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 attached to 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 are often involved, 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. 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 there is no change in the person in charge, such as sales representatives or construction management, smooth communication is possible.
We can provide consistent in-house construction from temporary scaffolding installation, exterior wall painting, to 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, and we are confident in our construction techniques.
We can also handle large-scale roofing projects such as 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.

6. Flexible and Prompt Response
Our company is equipped to handle various roofing troubles and situations.
If you cannot access the roof due to height, we can utilize a drone for assistance!
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 our skills 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 cases.

Our Proposal
We visited to provide an estimate and created a layout diagram for the solar panels based on the blueprints!
The layout diagram shows the arrangement of solar panels when placed on the roof.
Since we can also determine the installation capacity, it allows for power generation simulations and financial simulations.
We have also understood the expected amount of subsidies, so we explained this to the customer along with the estimate!
How to Choose a Solar Panel Installation Contractor in Zama City, Kanagawa Prefecture
There are many solar panel installation contractors available in Zama 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 confirm the following four points.
● Not only knowledgeable about solar panels but also have extensive knowledge about roofs
● Confirm the presence of warranties 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 in addition to solar panels
Many of the causes of poor installation of solar panels stem from a lack of knowledge on the part of the contractor.
While knowledge of 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 deteriorated roof, leading to leaks..
・Solar panels were installed on a roof with a short lifespan, necessitating a costly removal and reinstallation 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 maintenance
When choosing a solar installation contractor, be sure to check for warranties.
While solar panels and batteries come with manufacturer warranties, it’s also important to confirm whether there is a warranty for the installation in case leaks occur after the work is completed!
If the contractor offers a warranty period, they will address any leaks that occur after installation at no charge.
Additionally, some contractors provide aftercare services separate 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.
Aftercare maintenance allows for inspections of hidden areas, enabling early detection of issues and preventing major repairs or failures!
Kakeru Koumuten Co., Ltd. provides a leak warranty as part of the installation guarantee for solar panels.
We also conduct aftercare maintenance and send out annual DM notifications!
Please check the DM, and if you wish, we will visit you 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 same manufacturer is used for the same type of work, 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 obtain estimates from multiple companies.
When comparing estimates, please check carefully the following:
“Check the items in the estimate”
“Type of solar panels”
“Warranties and after-sales services”
Make sure to compare these details! 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 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 benefit by 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!
Subsidy conditions and amounts 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 helps reduce 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!!
Installing it on the roof or rooftop improves insulation properties.
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 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 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 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 inevitable risk of leaks due to these 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 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 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 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 panel and a 400W panel may seem at first glance that the higher output panel is better.
However, if the size of the panel does not fit well on the roof, there may be cases where “20 350W panels can be installed” and “15 400W panels 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 output of the roof)
350W × 20 panels = 7kW (total power output 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 to 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 output warranties, 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!
