How much maintenance does a solar energy system require?
Solar electric systems are for the most part, maintenance free. We do recommend a yearly check to ensure the system is operating properly and depending on the area, a periodic cleaning of the panels can be beneficial. A solar electric system should still be producing 80% of the panel’s rated power after 25 years and can last 40 to 50 years. Solar hot water systems have an expected lifespan of 25 or more years. Just as a plumbing system in a home or business may need periodic maintenance, solar hot water systems may need to have some electronics, pumps, or storage tanks repaired or replaced over time.
