S-Series, Energy Tanks

Thermal energy storage comprises a number of technologies that reserve thermal energy in tanks for later use. They can be employed to balance energy demand between day-time and night-time. The thermal storage tank may be maintained at a temperature above (hotter) or below (colder) that of the ambient environment.

SolarUS offers three options for thermal storage depending on the parameters of the system.

Available at 40, 60, 80, and 115 gallon sizes, including none, single, and double coil heat-exchanger configurations, with none, single, and double electric heating elements options.
