Energy Pay-Back Time of Photovoltaic Modules

摘要: The energy invested in photovoltaic modules has been investigated on the basis of currently operating commercial production lines France. analysis was made for two types solar cells, polycrystalline silicon and amorphous silicon. which calculated this way compared with produced by these under conditions various European climates. An average pay-back time 1.2 years 2.1 crystalline found. It can be anticipated that times will decrease future.
