Does Solar Panel Heating System really work to heat-up an Above Ground Swimming Pool?

This is a a follow up review of the XtremepowerUS 90105 4"-inch X 10'feet Spa Heater nground/Above Ground Swimming Pool Solar Panel Heating System. I have this for over a month now and so far, it has worked well to heat-up my pool water even though it is not getting full sun exposure the whole day.

My pool water jumps from around 78 degree to 81 degree on the day of the install. It continues to heat the pool water daily as long as I turn off the filter at night. Unfortunately, the pressure have decreased and I have to run the filter 24/7 to keep my pool water sanitized so, during the night, my pool water temperature goes back down to around 76 degree and the solar heater will heat it back up to around 81 - 84 degrees during the day making it comfortable when we swim at night.

My placement only gives me 2-3 hours of full sun exposure, and another 3 hours of partial sun exposure but it was still able to heat up the water to 84 degree. So, if you can place this in a direct sunlight, you should be able to heat your pool water better.
