The key is to know your winter/summer consumption ratio. Then you can set a rational collection angle.

Not much difference. It's an all electric home. The inverter is set up to sell at float voltage selling everything above that. Just doing simple snapshot math right now on a good sunny day with temps around 60* F, the system operates at 80% efficient. That number is more like 60% when its hot outside.
