Solar panel sizing calculator for in ground pool heating.
How many solar panels to run a 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.
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.
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.
The largest commercially available solar panels provide 200 watts of electricity an hour so a one horsepower pump would require four panels to operate.
You can buy a dc pool pump and dedicate 4 6 solar panels to powering it.
Calculate the amount of solar panels you will need to heat your pool.
A properly sized solar panel system will raise water temperatures adequately.
