Solar panels make more energy by maximizing the amount of sunlight collected. When panels are covered by dust or debris, they may not produce as much electricity.
SunPower Equinox home solar systems are more efficient, producing more energy even when they’re dirty or in the shade.
Our home solar systems don’t need much upkeep. Seasonal rains can wash off dirt, pollen, dust and other debris. If you reside in a dry, windy, location or there are trees nearby, your solar panels will need cleaning once in a while.
When the days begin to get longer in the spring, it’s important to give your panels a regular cleaning, to help your panels make more energy during peak production times.
How to Clean Solar Panels
Your panels may be ready for a cleaning when they no longer have a glassy or shiny look. For panels that are not visible from the ground, use your home solar monitoring app to check if the energy production has dropped.
For those who like home maintenance projects, you can carefully spray your solar panels with a hose and wipe them with a soft-bristled long-handled brush. Only do this if you can safely reach the panels and if they’re cool, either early morning or in the evening. Use cool water to avoid damaging the glass surface.
SunPower solar panels are extremely strong and durable, but don’t walk on them. For panels that are not accessible there are many affordable solar panel cleaning professionals. Some window cleaning services now also feature solar panel cleaning.
