How many solar panels do i need for pool pump.

Next you need to decide how many solar panels to purchase based on the size of your pool and how high you want to make the water temperature. You can buy a dc pool pump and dedicate 4 6 solar panels to powering it. However you can use the same procedure to estimate how many are needed. The largest commercially available solar panels provide 200 watts of electricity an hour so a one horsepower pump would require four panels to operate.

The solar panels are wired directly in to the pool pump via some power electronics and when the sun is shining your pool pump will run. Your pool pump is not connected to the grid so you will never pay for grid electricity to power it. You can use panels that are 4 x10 in size 40 sq. If you use 250w panels you need 27 of them.

Most pool pumps are rated between one and two horsepower and will draw about 800 watts of energy per horsepower for each hour of operation. Calculate the amount of solar panels you will need to heat your pool. Use the solar panel sizing calculator to determine the right amount of paneling you will need to heat your pool year round. And you can still claim the solar rebate for these panels even though they are not connected to the grid.

A properly sized solar panel system will raise water temperatures adequately. For a 24 round pool it s 3 14 x 144 452 sq. On the other hand if they are 330w panels only 21 are needed. Solar shingles are smaller than panels and their wattage is lower as a result.

In addition to the number of panels you need to judge if the the solar panels can be located close enough to the pool so the water heated in the pump can return to the pool still warm.
