Storage Volume. A small (50- to 60-gallon) storage tank is usually sufficient for one to two three people. A medium (80-gallon) storage tank works well for three to four people. A large tank is appropriate for four to six people. For active systems, the size of the solar storage tank increases with the size of the collector -- typically 1.5 gallons per square foot of collector.
Therefore, the supplemental storage must provide 22 gallons of water. If an additional 42. gallon tank, precharged to 20 psi, is installed and the pressure switch adjusted to 40-60 psi, the usable capacity o the primary tank will increase to 17 gallons and the second tank will. provide about 22 gallons.
