Hi,

I just installed photovoltaic panels on the roof and had to switch to time-of-use metering. This is going to make my pool recirculation more expensive, since I also have solar pool panels and I need to run the pump at peak hours (summer afternoons).

So I am considering a two-speed pump, but I am not sure if it will work for me. The current motor rating is 3/4 HP. I get plenty of flow---my pool is small (about 10,000 gallons) and I only need to run the pump 5 hours/day or so. The pump is 8 or 9 ft below the pool water line. The solar panels are about 20 ft above the water line. I am positive I can get by with a lower flow, but I still need a lot of head.

Does anybody have advice for this situation?

Thanks!
Luigi
