This provides a payback of between 1 5 and 7 years depending on your local fuel costs.
How many solar panels for pool pump.
1hp solar pool pump up to 100gpm 50ft head 90vdc brush type motor very quiet running motor use 2 solar panels 60vdc wired in series for small above ground pool or ponds for 500 5 000 gallons water filtration to 3 solar panels 90vdc wired in series for up to 3 000 25 000 gallon ingrond pool for filtration.
So you would want almost 600 sq ft of solar panel which is a lot of panels.
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.
A solar pool heating system usually costs between 3 000 and 4 000 to buy and install.
Solar panel sizing calculator for in ground pool heating.
Hi that s a big pool but still no problem for solar as long as you can install enough panels to do the job.
Your actual cost and payback depend on many factors.
You have 2 options for powering your pool pump with solar electricity.
A properly sized solar panel system will raise water temperatures adequately.
1 take your pool pump off grid.
I m not sure this kind of application will be practical considering you will need about 32 solar panels and many more batteries to operate the pool pump for a 24 hour period.
Without knowing the specifics of the pool pump a pump requiring 328 watts per hour will require 7872 watts for a 24 hour period.
The largest commercially available solar panels provide 200 watts of electricity an hour so a one horsepower pump would require four panels to operate.
They also typically last longer than gas and heat pump pool heaters.
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.
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.
So in rough estimate you need around 15 panels which will make around 4500 watts which will convert well enough to run your 2 hp pump.
Recommended would be to have 50 of the pool square footage 1152 in solar panel square footage.
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.
Selecting a solar pool heater.
Calculate the amount of solar panels you will need to heat your pool.
Take the wattage of the specific water pump and multiply it times how many hours a day it runs.
