Impact of Energy Losses Due to Failures on Photovoltaic Plant Energy Balance
(MDPI, 2018-02-03)
Photovoltaic (PV) plant failures have a significant influence on PV plant security, reliability, and energy balance. Energy losses produced by a PV plant are due to two large causes: failures and inefficiencies. Knowing ...
