10 Standards, photovoltaics Various standards must be complied with when erecting a photovoltaic system. You can find the most important European regulations here. DIN EN 62305-1 (IEC 62305-1:2006):2006-10 Protection against lightning - Part 1: General principles DIN EN 62305-2 (IEC 62305-2:2006):2006-10 Protection against lightning - Part 2: Risk management DIN EN 62305-3 (IEC 62305-3:2006):2006-10 Protection against lightning - Part 3: Physical damage to structures and life hazard DIN EN 62305-4 (IEC 62305-4:2006):2006 Protection against lightning - Part 4: Electrical and electronic systems...

11 Statutory requirements and insurance requirements Besides the current standards, the general statutory conditions and the requirements of the insurance companies must be taken into account. Please also observe the appropriate local legal requirements. Statutory requirements State construction regulations (LBO): Irrespective of a PV system, certain buildings require an external lightning protection system. Buildings requiring lightning protection by law include high-rise buildings, hospitals, schools and meeting places. Insurance requirements: VdS directive 2010 for risk- orientated lightning...

12 Sunny outlooks - Photovolatic solutions from OBO Nowadays, the solar sector is a booming part of the electrical industry. Because every investor sees a correlation between system function and claw-back time, protection against lightning and surge voltages plays a key role. Protection of the converter The converter is the core of the system, meaning that it is particularly at risk from couplings from surge pulses. Lightning protection, earthing, equipotential bonding and shielding measures along with proper cable routing can attenuate couplings. Damage to photovoltaic systems can be caused by...

13 Lightning protection equipotential bonding system and separation distance Important measures The following points must be taken into account in order to ensure comprehensive protection of the PV system: • The local earthing (EBS) must be connected to the main equipotential bonding systems (MEBS). • Equipotential bonding conductors must be routed closely and in parallel to the DC cables. • Data cables must be included in the protection concept. Table 1 provides an overview of the protective measures. Separation distance According to DIN EN 62305, the lightning protection system must be erected...

14 Rolling sphere method The method As a geometric-electrical model, the rolling sphere method represents the option of testing the protection areas against a direct lightning strike. An actual sphere is rolled over a model of the system and all the contact points represent possible points for direct lightning strikes. Securing photovoltaic systems with multiple interception rods If you use several interception rods to protect an object, you must take into consideration the penetration depth between them. Table 2 provides an overview. Figure 1: Planning method: Rolling sphere (R), rolling sphere...
