Solar hot water system panel size.

For an 80 gallon tank then you will need 53 square feet of collector. X is your set point temperature typically 135f y is the well mains water temperature. This particular solar water panel on average will produce 27 100 btu a day with mildly cloudy solar conditions. In the midwest and atlantic states you will need one square foot of collector per gallon of tank capacity.

Sizing ratio 1 15 8 34 x y z. A typical solar hot water panel is 2 square metres and will supply 150 litres. Use the solar panel sizing calculator to determine the right amount of paneling you will need to heat your pool year round. Use the formula below to do this calculation.
