Keeping up on solar
At 4 peak sun hours, counting 75% of the panel rating: 200 W of panels bring in about 600 Wh a day, more than the 448 Wh it uses at 8 h a day, so the station keeps up. 500 W of panels bring in about 1,500 Wh a day, more than the 448 Wh it uses at 8 h a day, so the station keeps up.
