Maintaining Your Solar System
Most new solar electric systems have a 20 year warranty. The average system degrades in output by approximately 1% per year. For example, in 20 years, a 1,000 watt system will produce approximately 800 watts of electricity.
Solar systems are low maintenance requiring occasional cleaning, electrical system checks and inverter preventive maintenance checks. Having your system inspected every year or two is recommended. Some companies offer maintenance agreements, or may include maintenance in your contract. Ask your solar professional for guidance on maintaining your system.
Exposure to the environment, pollen, dust and infrequent rain may create undesirable conditions for maximizing your solar systems out. When cleaned regularly they will produce the most energy. Frequency of washing should depend on location and weather conditions. Ask your solar professional for guidance on maintaining your system.
