Rain cleans solar panels only partly. A heavy Florida downpour rinses loose, dry dust off a tilted array, but it does not remove bonded films: pollen that dew has glued down, bird droppings, salt crust, lovebug residue, or the mud line that forms along the bottom frame. Those need a gentle hand wash with soft brushes and pure water. At a Glance Rain removes loose dust and some fresh pollen, mainly on panels tilted at a normal roof pitch. Rain does not dissolve bird droppings,

You should not pressure wash solar panels. Both Qcells and REC rule out high-pressure water in their manuals, because it can strip the anti-reflective coating, push water past frame seals, stress the cells, and void the product warranty. Clean solar panels with soft brushes, low-pressure water, and ideally deionized water instead. At a Glance REC states that pressure washers, steam cleaners and high-pressure hoses are "not permitted" on its panels "and will invalidate the war

During a Florida hurricane outage, a properly designed solar battery backup system separates the backed-up home circuits from the utility grid and then supplies those circuits from stored energy. If compatible solar remains operational, the panels can serve household loads and recharge the battery during daylight. At night, the home depends mainly on the energy that remains in storage. That sequence sounds simple, but reliable backup depends on the system controller, battery
