I live in San Tan Valley, AZ where it can get up to 122 during the monsoon season, we are in it now. I have both solar for our house and a separate system for our pool. Our electrical company is SRP and since I have solar the program I am on is one to watch the kWh between 2-8 PM. Thus I am currently operating my pump from 6 AM to 6 PM on low cleaning and then in between, heavy cleaning from 9 AM to 12 Noon and finally again for solar between 1 PM to 5 PM for a total run time of 12 hrs. I'm doing the solar time at the time SRP states to watch the kWh because the time is the hottest time of the day and I am producing the most energy. Does anyone believe the 12 hrs is way too much? My pool is inground 10680 gals kidney-shaped no trees around or the neighbors. My pump is a Hayward TriStar VS model SP3202VSP.
