I think you missed my point. The lowest speed uses 21 watts but the SWG isn't generating while the VSP uses 78 watts when the SWG is generating. 57 watts doesn't sound like much especially compared to 1230 watts at full speed but it adds up to 144 kW/hr of electricity.

How is your skimming doing at the lowest speed?If there is barely any movement then as cheap as 21 watts may sound, it is a waste of electricity.
Also, your calcs seem to be off, a 57 watt difference comes to about 42 kwh per month, not sure how you came up with 144kwh.

Right now I don't worry about skimming since the solar cover on the water surface prevents skimming. The math was a rough estimate. It was 14 hours per day x 180 days x 57 watts. I'm running the VSP at a higher speed for 10 hours per day.

Oh, I didn't realize it was over 180 days. I guess if 10 hours at higher speed is enough for chlorine generation, then it should be all good.

My pool has not seen 6" of rain in the last two years -- combined!

I'll verify the 6" number...we had 4.5" in 2 days and it rained for at least 2 more and I'm only an hour away from Apex. Dropped my salt by 300 points.
