Solar panels maintenance: it’s a question that comes to mind when you’re thinking about adding a solar energy system to your home. You’re worried about the maintenance required with solar panels on your home’s roof. Not to worry. A solar energy system is not like a household appliance or an automobile with moving parts and the kind of wear that you’ll experience driving your car on the highway.
Solar panels are fixed in place. The only moving part is the sun, which spins in place an average of 93-million miles away from the earth. A car’s tires are rolling, starting and stopping on the pavement. That’s why most tires are warrantied for between 30,000 and 100,000 miles. Your solar panels won’t travel miles unless you count the rotation of the earth. That’s a significant number since the earth turns about 1,000 miles every hour, 24,000 miles in a day and about 8.76-million miles in a year.
But, the miles that the earth spins really don’t count because your home, and your solar panels, are spinning with the earth. Most of the potential friction comes from the air, rain, snow and occasionally hail. The first three have a very low friction coefficient. With hail, you have repeated impacts on the solar panels. It’s not really a matter of friction. Without friction, solar panels maintenance is not a major factor.
Fortunately, solar panels are built to withstand the impact of hail. They’re even designed to withstand the impact of golf balls, if you happen to live near a golf course. According to a report by the National Renewable Energy Laboratory (NREL), from 2009 to 2013, approximately one-tenth of one percent of solar panel systems suffered some sort of damage due to hail and even hurricanes (depending on the quality of installation).
So, you really don’t have to worry much about maintaining your solar energy system. You should monitor production of electricity as a sudden drop in output, while it may relate to the weather, could indicate a problem where you should call in a professional to take a look. Otherwise, you really don’t even have to clean your solar panels.
