- Can a variable speed pump operate a pool solar heater?
Can I run my variable speed pump on low speed while operating solar panels?
Each solar panel requires a water flow rate of three to five gallons per minute. So let’s say we average that out to four and you have eight panels. Multiply eight by four– 32 gallons per minute. So if your variable speed is producing 32 gallons per minute on low, you’re good. If not, you have to kick it up a little bit.
Yes and if you don’t know what your variable speed is putting out, you’ll probably want to put on a flow meter. You can either get a digital one or a little analog one, it has a little bead that floats, it tells you how much water is being put out. And you want to make sure that you put it after your solar panels so it’s an accurate reading.
