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 ...

Economical and environmental analysis of thermal and photovoltaic solar energy as source of heat for industrial processes
(American Institute of Physics Inc., 2017-06)
Thermal energy for industrial processes can be generated using thermal (ST) or photovoltaic (PV) solar energy. ST energy has traditionally been the most favorable option due to its cost and efficiency. Current costs ...

A normalized variability index of daily solar radiation
(American Institute of Physics Inc., 2020-12)
The Variability Index (VI) is widely used to quantify the intra-day solar radiation variability. It compares the length of the global horizontal irradiance (GHI) or direct normal irradiance (DNI) profiles with the length ...
