Use a killer spray type pump up sprayer with lance & an adjustable jet and 1/4 cup of green Fairy liquid in 3 litres of water to spray the panels after giving then a good hosing down ,If you believe all the nonsense it will be halfway knackered if it’s 10 yrs old. It isn’t of course. Mine is maybe 5% down in 12 yrs, maybe less than that, they need a clean.
Agitate the soapy covering with a long handled soft brush and hose it off when you've done all the panels , then hose it off after another ten min or so . The green Fairy liquid has palm oil in it which helps future dust & crud come off when it rains ... last a good six months too .
