Reasons Why Kakeru Koumuten is Chosen for Solar Panel Installations in Chigasaki City, Kanagawa Prefecture
One reason our company is entrusted with solar panel installations by customers in Chigasaki City 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.
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 besides solar panel installation!
Most troubles such as leaks that occur during 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, the reality is that many lack knowledge about the roof and waterproofing at the installation site.
For peace of mind and to avoid maintenance issues and troubles after construction, it is safer 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. Specialized equipment for exterior renovations
Kakeru Koumuten Co., Ltd. has 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 and can assemble the scaffolding ourselves.
By performing 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 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 procure materials at a lower cost!
Additionally, we always have a stock of roofing materials, enabling 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.
While most contractors dispose of these materials together, sorting and recycling the waste can lead to significant cost savings on 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 the potential 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 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 the same person will handle everything, including sales and construction management, smooth communication is possible.
We can provide consistent in-house construction services from temporary scaffolding installation to exterior wall painting and roof renovations!
4. Various Permits and 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!

Our Proposal
We visited to provide an estimate and created a layout diagram for the solar panels based on the drawings!
The layout diagram shows the arrangement of solar panels on the roof.
Since we can also determine the installation capacity, we can perform power generation simulations and financial simulations.
We have also understood the expected amount of subsidies, and we explained this to the customer along with the estimate!
How to Choose a Solar Panel Installation Contractor in Chigasaki City, Kanagawa Prefecture
There are many solar panel installation contractors available in Chigasaki City, and it can be confusing to decide which one to choose.
Therefore, when requesting solar panel installation contractors or storage battery installation work, let’s confirm the following 4 points.
● Not only knowledgeable about solar panels but also have extensive knowledge 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 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 caused by contractor’s lack of knowledge
・Installing solar panels on a deteriorated roof, leading to leaks,
・Installing solar panels on a roof with a short lifespan, necessitating renovations to detach and reattach the solar 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 unforeseen 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 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 can be in hidden areas, you may not notice them yourself.
By conducting inspections during aftercare, you can detect abnormalities early and prevent significant repairs or failures!
Kakeru Koumuten Co., Ltd. offers a leak warranty as part of the construction warranty for solar panel installations.
We also provide aftercare services and send out annual DM notifications!
Please check the DM, and if you wish, we will come to perform aftercare services!
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 involved and the same work is being done, costs may vary, as well as warranties and after-sales services.
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 contractors.
When comparing estimates, please check carefully the
“Confirmation of estimate items”
“Types of solar panels”
“Warranties and after-sales services”
and make your judgment! Avoid deciding 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 Power Equipment
The benefits of installing solar panels are as follows!
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 by consuming the electricity you generate!
Electricity prices are expected to continue rising, 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 amount through subsidies is a significant advantage!
Benefit 3 Environmentally Friendly!
Solar power generation reduces carbon dioxide emissions and decreases reliance 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.
Advantage 4 Improved Insulation Effect!!
Installing on the roof or rooftop improves insulation properties.
Especially in summer, it can effectively block direct sunlight, providing significant heat shielding benefits!
Advantage 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 may be 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 reassuring to request a simulation that considers 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.
This inevitably increases the 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.
Dedicated Catch Base Hardware for Horizontal Metal Roofs
Note 3: The Roof Will Become Heavier
As solar panels are 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.
There is no definitive answer to “which 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 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 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 installation capacities on the same roof due to the size difference.
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 years and 20 years.
After 30 years, some may decrease by 40% 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.
For output warranties, some manufacturers offer a 30-year warranty while others provide a 10-year warranty, so it can differ greatly!
The longer the warranty, the better, so let’s check the warranties of the manufacturers you are considering!
