Solar energy systems, in general, do not necessitate a lot of upkeep. All you have to do is keep them clean. Most reputable solar panel manufacturers provide warranties of 20 to 25 years. There is no wear and tear because there are no moving parts. Because it is always working to convert solar energy into electricity and heat, the inverter is usually the only part that needs to be replaced after 5-10 years (solar PV vs. solar thermal). Apart from the inverter, your solar power system's wires must be maintained to ensure maximum efficiency.
