Solar thermal systems have multiple uses; for example, water heating, room heating and cool-water exchangers. Renewable energy is considered to be one of the solutions to reduce environmental pollution.
Japan is also planning the "Energy from the Desert" project -- intended to establish large scale PV power generation systems in the deserts in cooperation with National University of Mongolia.
These new "quality control" measures introduced by the Japanese government should result in better planning, management and growth of the renewable sector and lead to greater development certainty for developers and the actual successful implementation of renewable projects.
Among them, solar energy is considered as one of the most promising energy alternatives. Solar energy is used as Photovoltaic PV for electricity and solar thermal for heating.
Dif-ferent FIT rates were set for different types of renewable energy sources e.
This article will provide a brief overview of the Japanese solar PV market and the effects of some of the recent legislative changes to the FIT regime on such market. The recent changes to the FIT regime introduced tighter requirements to the certification process to require developers to provide more detailed information about their proposed project.
Under the new system, METI will solicit bids from developers for a certain identified generation capacity.
Although the FIT regime has been effective in incentivising investments in the re-newable sector, the generous FIT rates have had an adverse impact on domestic elec-tricity prices as the costs of the Japanese FIT regime are indirectly borne by Japanese consumers in the form of a renewable energy levy included in their monthly electricity bill.
Solar thermal requires large equipment, which is relatively difficult to install in households.
