Where do you put surge protectors in solar panels?

When it comes to commercial and utility-scale systems, Sylawa suggests using the 10-m rule. For installations with DC cable lengths under 10 m (33 ft), DC solar surge protection should be installed at a convenient point such as at inverters, combiner boxes or closer to the solar modules.

Where do I plug my surge protector?

Connections of a SPD to the loads should be as short as possible in order to reduce the value of the voltage protection level (installed Up) on the terminals of the protected equipment. The total length of SPD connections to the network and the earth terminal block should not exceed 50 cm. L = L1+L2+L3.

Can solar panels be damaged by power surge?

Lightning strikes to unprotected rooftop solar panels will cause damage at the strike point, as well as lightning surge damage to any equipment that is connected downstream. … The destruction that lightning and power surges can cause are usually extremely costly to repair or replace.

What happens if lightning strikes a solar panel?

If the lightning bolt strikes your system directly, it can melt the panels or inverter. Thankfully, direct strikes are rare. … If lightning strikes close to the solar system, a branch current from the bolt can flow over the solar panels, resulting in high-voltage surges which can damage various system components.

How do I choose a SPD for my solar system?

The number and location of SPDs on the DC side depend on the length of the cables between the solar panels and inverter. The SPD should be installed in the vicinity of the inverter if the length is less than 10 metres.

Is it safe to touch a solar panel?

Solar panels are designed to be safe and to be touched, as long as you touch the glass or the aluminum frame.

Can you walk on a solar panel?

Don’t walk on your solar panels! … Solar cells are easy to break. But when they’re packaged in the module, it can be impossible to see this damage. After a cell is cracked, the effect on the solar panel’s power output becomes worse over time.
