SOLAR POOL HEATER
It's important to note that installing solar pool heater panels in the shade during the Solar Window [9:00 am to 5:00 pm] will decrease the efficiency of your system depending on the percentage of area and length of time they are in the shade.
When selecting the best location for your solar pool panels use Google Maps to look around for potential obstacles that may cause your solar panels to receive shade.
Be sure to choose a suitable location on your roof or on the ground that you believe to have the least amount of shade during the daily solar window period. Little to no shade is optimal.
If in the event the location you selected does have some shade during the solar window period, to compensate for the decreased efficiency you may want to add an additional solar pool panel to your system to increase your solar panel square footage. The more panels you have installed the more solar radiant energy you will collect during the solar window period.
