Lightning protection for solar thermal power plants
An effective lightning protection system (LPS) is necessary for a PV system depending on the location, construction type and utilisation. However, due to financial issues and no mandatory requirement from the Regulator, most, if not all, of the building managements have opted not to install a LPS.

This paper can help engineers design effective lightning protection system for PV systems and select appropriate protective devices. Solar photovoltaic (PV) system is one of the promising renewable energy options for substituting the conventional energy. PV systems are subject to lightning damage as they are often installed in unsheltered areas .
Photovoltaic systems are inherently exposed to direct and indirect lightning effecfs. For high- capacity systems, the deployment of solar cell arrays requires a large area with commensurate exposure to direct lightning strikes at the local annual rate of ground strikes per unit area.
The lightning failure mode of bypass diodes is identified for the first time. The results can help to design effective lightning protection and select appropriate parameters of protective.
4.1 Protection against direct lightning. When located outside the existing zone of protection on a building (see electro-geometrical pattern), a photovoltaic system needs a discreet protection device to protect it against lightning strikes. Two common situations are described in Figure 1.
