Presented at: PV in Europe - From PV Technology to Energy Solutions Conference and Exhibition, Rome, Italy, 7-11 oktober 2002.
Abstract:
PVT collectors are thermal collectors in which a PV-laminate functionsas the solar thermal absorber. In this way, a collector is generated
that produces both heat and electrical power. A consequence of integrating
a PV laminate in a thermal collector is a potentially high PV temperature,
especially under stagnation conditions. In this paper, a numerical model
to calculate this temperature is validated and estimates are made of
the maximum PV temperature under stagnation conditions for various locations
in Europe. It will be shown that for the prototype presented here, in
the North of Europe the collector temperature will stay below 130 °C.
This is important, since the risk of EVA delamination increases strongly
for temperatures over 135 °C.
