近年、様々な環境問題に対処すべく自然エネルギーを積極的に利用することが注目されている。取り分け、極めてクリーンであって実質的に無尽蔵と言うことができる太陽光の利用が、これからの自然エネルギーの利用における主たる役割を果たすものとして期待されている。   In recent years, active use of natural energy has been attracting attention in order to cope with various environmental problems. In particular, the use of sunlight, which is extremely clean and virtually inexhaustible, is expected to play a major role in the future use of natural energy.

エネルギー源としての太陽光の利用に際しては、太陽光エネルギーを直接的に電力に変換する太陽電池を用いて行う利用形態が、結果的に利用効率が比較的高いことになる。太陽電池は、半導体による光起電力効果によって電力を得るものであるが、現在実用化されている太陽電池は、単独で供給できる電力が比較的小なるものにとどめられている。それゆえ、複数の太陽電池を直列または並列に接続して全体としてパネル状を成すものとし、全体として所定以上の電力が得られるようにした太陽電池モジュール、さらには、複数の太陽電池モジュールを直列または並列に接続して、必要とされる電力が得られるように設置した太陽電池アレイ等が、広く実用に供されている。   When using sunlight as an energy source, the utilization form performed using a solar cell that directly converts solar energy into electric power results in relatively high utilization efficiency. A solar cell obtains electric power by a photovoltaic effect by a semiconductor. However, a solar cell that is currently put into practical use has only a relatively small amount of electric power that can be supplied independently. Therefore, a plurality of solar cells are connected in series or in parallel to form a panel as a whole, and a solar cell module that can obtain a predetermined or higher power as a whole, and further, a plurality of solar cell modules are connected in series. Alternatively, solar cell arrays and the like that are connected in parallel and installed to obtain the required power are widely used in practice.
