Solar panel maintenance means keeping the glass clean so the panels catch the sun, and checking the array for dirt, leaves and damage after storms. A wash with a soft brush and mild soap, a rinse and a look over the mounts from the ground covers the routine for many home arrays. The steps below walk through that routine, and the gear section names the kits that handle each part.

Solar panel maintenance: the quick answer
Wash the glass when dust, pollen or bird droppings dull the surface, rinse the soap off and let the glass dry clear. A water fed brush on a telescoping pole does the wash and the rinse from the ground, and a soap dispenser in the kit feeds mild soap through the brush head. Check the array after storms for leaves and debris, and wash again when the glass looks dull. The kits below handle the wash, the rinse and the dry, and the cleaner handles the soap.
Step 1: Wash the glass
Start with the wash, and let the brush and the soap do the work. The Buyplus kit lists a 20 inch brush with 4 high-flow nozzles on a pole that extends 5 to 24 ft, the IGAD kit lists a 16 inch brush with 4 water jets and a 10 inch brush with 2 water jets on a pole that extends 4 to 18 ft, and the IGADPole kit lists a 20 ft pole with a water fed brush and a soap dispenser. The Teexpert cleaner (on Amazon) is the soap for the wash: a 32 oz concentrate that makes 150 gallons of ready-to-use spray, ammonia-free and phosphate-free. Spray the cleaner on, wash with soft bristles and keep the glass wet until the rinse.
Step 2: Rinse and dry
Rinse from the top of the panel down until the water runs clear, then pull a squeegee across the glass so it dries without streaks. The IGADPole kit lists a 10 inch squeegee for the drying pass, and the Buyplus kit lists a squeegee with a detachable microfiber cloth and a 180-degree angle adapter. The IGAD kit lists a 33 ft hose with a universal garden tap adapter, so the rinse water comes through the brush head at the tap. A water fed brush rinses while it washes, which keeps grit from dragging across the glass.
Step 3: Check the array
After the wash, look over the array from the ground for leaves, debris and damage, and check the glass for streaks once it dries. The IGADPole kit lists a cobweb duster for gutters and high corners, and the Buyplus kit lists a cobweb duster for spider webs and dirt in narrow spaces. Wash again when the glass looks dull, and check the array after storms when leaves and debris gather on the panels.
The gear for solar panel maintenance
The wash needs a brush and a pole, the rinse needs a hose and a squeegee, and the soap needs a dispenser or a concentrate: the kits below cover those parts, ranked by their scores.

Detailed Review
The listing states a 20 inch water fed brush with 4 high-flow nozzles, a soap dispenser, a cobweb duster, a squeegee with a detachable microfiber cloth and a 180-degree angle adapter, on a 5 to 24 ft aluminum telescoping pole with 4 flap locks, 2 non-slip foam handles and a pre-attached hose. The title lists a 30 ft reach while the pole itself extends 5 to 24 ft, and the listing does not explain the gap.

FAQ: power away from the grid
How often should I wash solar panels?
Wash them when dust, pollen or bird droppings dull the glass, or after a long dry spell leaves a film on the panels. Panels near trees, roads or fields gather dirt faster than panels in open ground, so check the glass after a dry spell and wash when the surface looks dull.
Can I clean solar panels with a pressure washer?
The kits in this guide connect to a garden hose, not a pressure washer, and wash with soft bristles and mild soap. High-pressure water can mark the glass and force water under the panel frame, so a hose rinse and a soft brush is the safer route. See the best solar panel cleaning kit for a pressure washer for options built around a pressure washer.
Do I need a ladder to clean roof panels?
Often not. The Buyplus pole extends 5 to 24 ft for a 30 ft reach, the IGADPole kit lists a 20 ft pole, and the IGAD kit lists a pole that extends 4 to 18 ft, so a ground-level wash covers many roof arrays. The Teexpert cleaner needs a brush and pole of its own, since the bottle holds only the cleaning solution.
What should I use to wash solar panel glass?
Use a soft-bristle brush, mild soap and a garden hose. The kits in this guide use soft bristles and soap dispensers, and the Teexpert cleaner is an ammonia-free and phosphate-free concentrate that makes 150 gallons of spray. Rinse until the water runs clear and let the glass dry.
