We survey roofs, plan rooftop photovoltaic systems and home batteries for houses and small buildings, and help with the grid-connection and FIT paperwork. We also look at existing systems: cleaning, inverter checks and battery add-ons. What exactly we do on a given project is written in its quote.
Our office is in Marugame, Kagawa; the address is on the Contact page. We do not publish a service area. Tell us where the property is and we will say by email whether a visit is realistic.
Residential solar systems of 4-6 kW and of 7-10 kW, and home battery retrofits. Every project is quoted individually after a survey, and we do not publish a price list.
Whether a survey is charged, and how much, is stated in writing before any visit is booked. The findings are given to you in writing whether or not you go on to an installation.
No. We give estimates together with their assumptions. Actual output depends on the weather, shading, the condition of the panels and how you use electricity, and tariffs and subsidies change over time.
We help prepare the documents for the grid connection and the FIT registration; you stay the applicant. We do not quote subsidy amounts on this site, because programmes differ by prefecture and municipality and change. Check the Agency for Natural Resources and Energy and your local government, and tell us what you find.
Electrical work on a solar system is regulated and has to be done by qualified people. The written quote names who will carry out the work and which registrations they hold. We do not print licence numbers on this website, so please ask for them in writing before you sign.

No. This website has no shop and takes no payments. Prices, payment methods and dates are given in the written quote; the commercial notice sets out the details the law asks us to state.
