Solar Hot Water System Panel Size

For an 80 gallon tank then you will need 53 square feet of collector.

Solar hot water system panel size.

A properly sized solar panel system will raise water temperatures adequately. Sizing ratio 1 15 8 34 x y z. Using these output measurements we can determine how many square feet of collector we will need to heat a single gallon of water. By raising water temperature your swimming season can be extended in colder locations by as much as 100 and works year round in warmer weather.

Z is the btu ft2 rating of the solar collector. So a typical 4 person family will need a system sized at 300 litres which has 2 panels. 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.

At the end of the day a good installer will look at your usage and advise you exactly what size to go for. 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. Use the formula below to do this calculation.
