Advantages of the SOL Perpetua™ System

On account of the bubble pump, the SOL Perpetua system has these advantages over other solar water heating systems:

  • The SOL Perpetua™ system is passive

    The power required for the pumping action is derived from the heat source, i.e. the sun. Even this energy is returned to the system as thermal energy due to friction.

  • The SOL Perpetua™ system is self-controlling

    Because the sun powers the bubble pump, pumping action stops at night or when the sun's heat is blocked by clouds or trees. The stronger the sunshine, the faster it pumps.

  • The SOL Perpetua™ system has no moving parts

    Only the working fluid moves. There is no motor, mechanical pump, electronic controller, temperature sensors, wiring, expansion or draindown tank, or operating valves.

  • A SOL Perpetua™ system does not overheat the working fluid

    When the storage tank is full of hot water, a space heaterdrier cools the working fluid and prevents damage to the antifreeze in it. Corrosion caused by an acidic working fluid is thereby avoided.

  • The SOL Perpetua™ system is simple

    Compare the schematic in Figure 4 with any electrically pumped system. Simplicity means lower initial cost and long, trouble free service.
