Lightning and surge protection for rooftop photovoltaic systems
Section 4.5 (Risk Management) of Supplement 5 of the German DIN EN 62305-3 standard describes that a light-ning protection system designed for class of LPS III (LPL III) meets the usual

Lightning protection systems (LPS) provide a protective zone to assure against direct strikes to PV systems by utilizing basic principles of air terminals, down conductors, equipotential bonding,
protection between all sets of conductors, for optimum surge protective performance. The Furse ESP combined Type 1+2 SPDs for PV systems ESP DC550/12.5/PV and ESP DC1000/12.5/PV - are
A distinction is made between lightning protection levels I, II and III/IV, with the probability of lightning damage increasing from lightning protection level I to lightning protection level III/IV.
Before the design of the lightning protection system, a risk assessment must be performed by the protection engineer to determine the lightning protection class of the project.
Lightning protection level (LPL): Classification I-IV defining minimum and maximum lightning current parameters the protection system must handle. Determines rolling sphere radius,
Therefore, and for reasons of regulations and safety, every PV plant design project must include a comprehensive system to protect it against lightning and power surges. This document presents a
What are lightning protection classes (LPL)? The different lightning protection classes, also known as Lightning Protection Levels (LPL), only refer to the type I arrester and its impulse current 10/350 µs.
These levels specify the minimum and maximum lightning current parameters the protection system must manage, based on the statistical probability of a strike''s severity. LPL I
According to IEC 62305, Lightning Protection Systems are divided into four classes (I, II, III, and IV), depending on the level of protection required and the potential risk to the structure or facility.
