Solar panel maintenance involves regular cleaning and inspections to ensure the system functions properly. Solar panels may need to be cleaned at least every few months and sometimes more often if they're located in dusty or dirty areas. However, according to some experts, rainfall is usually enough to keep them clean. Inspections should be performed annually by a qualified solar panel installer or electrician. Regular maintenance can help extend the life of your solar power system and, over time, can help maintain power production.
With so many different types of solar panels on the market, choosing the right one can take time and effort. Two of the most common types of solar panels are monocrystalline and polycrystalline panels.
Solar panel efficiency refers to the percentage of sunlight converted into usable electrical energy by a solar panel. It measures how well a solar panel can convert sunlight into electricity.
