Will cleaning my solar panels void the warranty?
Not if you clean them the way your panel maker says. But the wrong method can: Trina Solar and Canadian Solar both say wrong cleaning voids their warranty.
So check your manual first. The limits are not the same for every brand.
What do the panel makers say?
Trina Solar
Use a soft, clean cloth, a sponge or a soft brush. Keep water pressure to 4 MPa or less. Wrong cleaning voids the warranty (manual).
JinkoSolar
Never use anything rough. Keep water pressure under 675 kPa. Chemicals may affect the warranty (manual).
REC
A garden hose at normal house pressure is fine. Pressure washers, steam cleaners and metal sponges void the warranty (guide).
Canadian Solar
Damage from the wrong cleaning voids the warranty, says its European manual (manual).
Can I use a pressure washer on solar panels?
Check your manual. REC says no pressure washers at all. JinkoSolar and Trina give pressure limits, and they are not the same.
That is why we clean panels with a soft rinse, not a pressure washer.
How much is a solar panel clean?
$349 for up to 20 panels. Add it to a house wash on the same visit. See solar panel cleaning.
