PURPOSE:To improve the energy recovery efficiency per apparatus installation area by a method wherein first solar cells are attached above heat medium tubes with their light receiving faces up, a second solar cells are attached under the heat medium tubes with their light receiving face down, the heat medium tubes with solar cells are enclosed in transparent glass tubes, and a reflection plate is provided under the glass tubes to reflect solar rays. CONSTITUTION:First solar cells 2 are attached above heat medium tubes 1 with their light receiving faces up and convert solar rays A radiated from above the heat medium tubes 1 to electric energy and thermal energy. Second solar cells 3 are attached under the heat medium tubes 1 with their heat receiving face down, and a corrugated reflection plate 5 is continuously provided under the heat medium tubes 1 and outside transparent glass tubes 4. Therefore, solar rays B passing through gaps between adjacent solar cells 2 are reflected by the reflection plate 5 and reach the second solar cells 3 where solar rays are converted to electric energy and thermal energy. The electric energy is collected through lead wires, and the thermal energy is collected via heat medium flowing along the heat medium tubes 1. |
