What are solar panels?
This page will explain the recommended points, precautions, and costs associated with solar panel installation!
Solar panels are devices installed on rooftops or roofs that generate electricity from sunlight.
In Tokyo and Kawasaki, it has become “mandatory” for new buildings, and due to rising electricity costs and generous subsidies, the number of installations has increased in recent years.
Solar panels are also referred to as solar modules or solar cells, but they mean the same thing!
What are the benefits of installing solar panels and storage batteries?
Kakeru Koumuten’s exterior wall cover method has received positive feedback for its “five key points”!
Point 1 Economic benefits
The biggest advantage of introducing solar panels is the economic benefit!
While the selling price of electricity has decreased compared to ten years ago, the rise in electricity costs allows you to benefit from self-consumption of the generated power.
If you plan to use the generated electricity at night, installing a storage battery is essential!
Point 2 Subsidies can be utilized!
Conditions and amounts for 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!
Point 3 Environmentally friendly!
Solar power generation has low carbon dioxide emissions and reduces dependence on fossil fuels, contributing to the mitigation of global warming.
Since there is no noise or harmful substance emissions during the generation process, it is considered an environmentally friendly method of power generation.
Point 4 Improved insulation effect!!
By installing it on the roof or rooftop, you can block direct sunlight.
Point 5 Electricity can be used even during power outages!!
Only when a storage battery is installed, it is possible to use electricity during emergencies in case of a power outage!
What should you be careful about when installing solar panels?
Next, I will explain the “three points to be cautious about” when installing solar panels!
Caution 1 Maintenance costs are incurred
The maintenance costs are related more to the roof where the solar panels are installed than to the solar panels themselves.
If you perform a roof renovation after 10 to 20 years, there will be costs for 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!
Caution 2 The risk of leaks increases depending on the roofing material
For slate roofs and tile roofs, it is necessary to make holes in the roof to secure the solar panels.
As a result, there is an unavoidable risk of leaks due to the holes made in the roof.
Of course, waterproofing will be properly done, 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.
Caution 3 The roof will become heavier
Because solar panels are placed on the roof, it will become heavier. For tile roofs, it may be reassuring to replace them with lighter roofing materials.

About the Costs of Solar Panel and Battery Installation
This is a guideline for the costs when installing solar panels and batteries!
The estimate for the installation of solar panels will be determined based on the following items:
・Installation capacity of solar panels (number of panels)
・Installation capacity of the storage battery (three patterns: 5 kW, 10 kW, 15 kW)
・Length of wiring to be used
・Scope of temporary scaffolding installation
・Type of existing roofing material (the type of base brackets used will vary depending on the roofing material)
・Arrangement of solar panels (the amount of brackets used will differ based on the arrangement)
・Distance for material transportation
and more
| Installation Capacity | Solar Panel Installation Cost | Battery Installation |
| 3kW～5kW | 800,000 yen～1,200,000 yen | 1,000,000 yen～1,300,000 yen （5kW range） |
| 6kW～10kW | 1,200,000 yen～1,900,000 yen | 1,300,000 yen～1,600,000 yen （10kW range） |
| 11kW～15kW | 1,900,000 yen～2,500,000 yen | 1,700,000 yen～2,000,000 yen （15kW range） |
