Solar power systems are very robust and last for 25 years or more. There are no moving parts and therefore there is very limited wear and tear. In addition, there is no periodic maintenance that is required. Most solar power systems come with many warranties and guaranties including a solar panel product warranty, solar production guarantee, inverter product warranty and workmanship warranty. In the unlikely event that your solar power system develops a problem, our installation partner is usually able to resolve it as part of the warranties and guarantees that cover workmanship, equipment and system performance.
