Zhao et al. (2013) focus online–line faults in photovoltaic arrays that may be caused by short-circuit faults or double ground faults, the work examines the challenges to Overcurrent Protection Devices (OCPD) in a photovoltaic array brought by unique faults: one is a fault that occurs under low-irradiance conditions, and the other is a fault that occurs at night

Solar Photovoltaic (PV) Systems

The ratio of solar PV supply to power grid supply varies, depending on the size of the solar PV system. Whenever the solar PV supply exceeds the building''s demand, excess electricity will be exported into the grid. When there is no sunlight to generate PV electricity at night, the power grid will supply all of the building''s demand.

Photovoltaic (PV) Solar Panels

Under typical UK conditions, 1m 2 of PV panel will produce around 100kWh electricity per year, so it would take around 2.5 years to "pay back" the energy cost of the panel. PV panels have an expected life of least 25 to 30 years, so
