How Are ADSL, Modems, and Splitters Protected Against Lightning?
14 February 2016Solar power plants have become a rapidly growing sector in recent years. These plants, which require serious investments, are expected to operate efficiently for an average of 25 years. However, solar power plants are an area that involves multiple risks and therefore requires serious risk management. Recent research conducted by insurance companies shows that the greatest danger for solar power plants is overvoltage surges.

Solar power plants are most frequently damaged by overvoltage surges at a rate of 31%. (Values are averages and may vary from plant to plant.)
So, At What Cost Can You Protect Your Solar Power Plant Against Overvoltage Surges?
As seen above, overvoltage surges are the most important cause of damage to power plants. So, at what cost can we protect our plant against lightning and overvoltage surges? As shown in the infographic below, a 1 MW power plant can be fully protected against lightning and overvoltage surges at a cost of less than 1% of its total investment cost. The key point here is that the lightning and overvoltage protection system is implemented in accordance with IEC 62305 standards.

In a 1 MW solar power plant, lightning protection systems constitute only 1% of the total cost. Values are averages and may vary from plant to plant.
