Hybrid solar collector for water heating and electric current generation, with photovoltaic module centrally located on hybrid collector

摘要

Hybrid solar collector locates in its middle part photovoltaic module, whose photovoltaic generator (1) is surrounded by vacuum tube collectors on left and right side. Preferably, vacuum tubes (2,2a) are fitted round photovoltaic module at same level to prevent mutual shading.Compound parabolic concentrator (4) lies 17mm below vacuum tubes for optimal utilisation of solar radiation, with concentrator mirror W-shaped. In collector, condenser is directly surrounded by heat exchange liquid for optimum heat exchange. Transition from heat pipe to collector tube is formed by special, long service life seal. On collector rear side is fitted air and water cooler for photovoltaic module.
