In "House that makes the most of the sun-early summer-", we offer two plans, "Roof rental joint business plan" and "Self-purchase plan".
The roof rental joint business plan is a system in which a power generation company concludes a roof lease contract with multiple owners, installs solar panels, and makes the power generated by each house collectively 10kw or more and purchases it from the power company. The ownership of the electricity belongs to the power generation company, and it is returned to the landlord in the form of "roof rent".
There is no initial cost or maintenance cost, and there is an advantage that even a house with less than 10kw can earn 20 years of electricity sales income. After the 20-year contract period ends, the solar power generation system will be transferred free of charge.
On the other hand, the self-purchase plan is a plan equipped with a solar system that generates 10kw or more. Furthermore, by using the company's tie-up loan and the national housing system, it seems that the mortgage can be reduced by up to 8.84 million yen.
In addition, it is possible to sell electricity at the same house for 20 years, which is 1 yen / kw higher than the electricity selling price under the feed-in tariff system. It is said that it can sell electricity for 30 yen now and 28 yen (both tax excluded) from July.
