Cogeneration system and method for the combined heat and power generation from solar thermal energy

摘要

Cogeneration system for thermal and electric energy production from thermosolar energy, comprising a solar field connected to a power island by means of a piping system through which a heat transfer fluid (6) flows. The piping system comprises pipe collectors and a thermal insulating system (2). The system has at least a photovoltaic panel (3) placed over the piping system, connected to at least a battery (4) further connected to heating means (5) placed at the pipe collectors (1) configured to receive power from the battery (4) and to heat the heat transfer fluid (6) to a temperature suitable for the operation of the power island during periods of low or non-existent solar radiation. The invention further relates to a cogeneration method, which comprises harvesting solar energy by photovoltaic panels (3), storing the energy in batteries (4) and heating the heat transfer fluid (6) by means of heating means (5).
