In addition to PV technology, concentrating solar thermal power (CSP) and concentrating photovoltaic technology (CVT) are used to convert solar energy into electricity.
Typical representation of CSP has been indicated in Fig. 3. However, current generated by photovoltaic technology is fed into grid systems for better efficiency.
Roughly 90% of current generating capacity from photovoltaic consists of grid field electrical systems.
Grid field insulation is either ground mounted or built on the roof of the building to increase the efficiency of light capacity by PV system.
PV system has to be labeled properly to indicate their capacity and
durability. Usually, their capacity ranges from 10–60 MW [22].
Their durability varies according to the maintenance condition and loading. A well-developed PV panel can operate satisfactorily for up to 10 years at 90% capacity and 25 years at 80% capacity [23].
Its efficiency is not consistent as it is influenced by many
