12. Is it costly to maintain solar panels?
Solar panel systems are made of durable tempered glass. They have a longer lifespan and require little to no maintenance for the 25 to 35 years that they will generate power. In most cases, you don’t even need to clean your solar panels regularly. If something does happen, most equipment manufacturers include warranties. However, warranty terms depend on the company, and if the company is still in operation at that period.
