My neighbor's solar panel tip cut our June bill by 40%
Last spring our neighbor Dave in Austin kept pushing us to clean the panels with a hose at dawn, not midday when they're hot. We shrugged it off until our June bill hit $220, then tried his trick for two weeks. Our usage dropped from 1,100 kWh to 640 kWh, which honestly surprised me more than he said it would. Has anyone else found simple maintenance like this making that big a dent, or did we just have filthy panels before?
My uncle tried something like that with his gutters years back. He swore cleaning them out every fall dropped his winter heating bill because the meltwater stopped backing up under his shingles or something. Never made sense to me but the man was CONVINCED. He even kept a little notebook with dates and temps written down. We all just nodded along at Thanksgiving. Miss that stubborn old guy.
