SolFlow’s PV Direct Hot Water is a solution that’s simple to install, with no pumps to replace, no moving parts and no plumbing on your roof.
Our unique controller harnesses the sun, which then sends the DC electricity to a specially made DC element in the water storage tank (on the ground) to heat the water to the optimum temperature. The controller monitors the process and when optimal temperature is achieved the DC electricity is diverted either to other appliances, Battery Storage or to the Grid.
Unlike some other solar hot water technologies, there are no additional pipes or expensive pumps required and tubes don ́t need to be insulated from the cold. Cabling is minimal and therefore easier to install and suffers less power loss.
In fact, the Direct Current generated by the solar modules and fed directly into the heating element has an electrical efficiency of 99.6%, saving you even more money on your water heating bills.
And to ensure there’s always hot water on cloudy days or at night time, the SolFlow solution allows you to add an electric or gas booster to ensure a round-the-clock supply of piping hot water.
