Comment: It was interesting to note that at times the irradiation exceeded 1150 m/sq.ft when the sun was "lighting up" the clouds. A clear blue sky isn't always the highest irradiance

Comment: Heavy electric car usage ... I average a couple of 20-40 mile trips per day. Basically, my PV system is providing all the power I need for the car, with not much excess left over. On May 19th, the "Utility meter" read 2226. Today it reads 2223. This means that since the beginning, I have produced 30 kWH of excess power beyond what was needed for car charging. (You multiply the meter reading x10.) The total power produced since start, however, is 611 kWH. This is about what an average house uses in one month.
