Impact on the Roof
The roof of a house is not originally designed for the installation of solar panels. In typical construction methods, holes are drilled into the roof to install brackets that secure the solar panels, which can affect waterproofing. It is important to choose a reliable and trustworthy contractor who provides sufficient explanations, and to thoroughly check the construction details, aftercare, and warranty information.
Tax on Electricity Sales Income
Income from selling electricity generated by solar power is not fully exempt from taxation, and there may be cases where it is subject to tax. If your total income from sources other than salary exceeds 200,000 yen, you will need to file a tax return.
Regions Requiring Caution for Installation
While solar power generation systems are widely adopted across the country, there are regions where caution is necessary for installation.
