How long does a solar panel last?
Most solar panels have a guaranteed lifespan of 25 years-30years.
Can the solar panel be damaged by wind/snow?
Solar panels are well attached to the roof and can take a beating. The panels are so well secured that they can even withstand speeds of up to 150 km/h . Since the surface of the solar panels is very slippery, the snow will slide off in most cases. As a result, the generation of solar energy is often not hindered. An ice layer can form on the solar panel, which will melt away automatically as soon as it stops freezing.
How much maintenance do I have to do on my solar panel?
Solar panels require little maintenance. Solar panels last at least 25 years, while the inverter lasts 10-12 years. This inverter will therefore have to be replaced halfway through its use. It is advisable to clean the solar panels once in a while, so that optimal solar energy can be generated.
