Yep, even solar panels need a good scrub every now and then. In order to keep the electric output at optimum levels, the dust and soot from L.A.'s notorious air need to be washed off every now and then- and today was a good time for that. So we went up and hosed and scrubbed the dirt off to make'em shine again. Since the system got turned on, we have produced over 2,400 kWh with an excess of 1000 kWh. The mild summer along with the other energy saving features of the house helped a lot to keep actual power usage low for us. But we have not been in the house for a whole year and it is a bit early to make predictions about the overall performance.
