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 DC element has a uniquely designed over temperature cut out system with unique IP protected technology. The controller monitors the process and when the preset temperature has been achieved, instead of the solar panels remaining idle, they are connected directly to other appliances such as Battery Storage or a Grid Tie Inverter.
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, Direct Current is far more efficient than its Alternating Current counterpart. Solar Panels produce Direct Current Energy, the SolFlow controller manages Direct Current Energy to the Direct Current Element. By keeping the energy in the same format, an electrical efficiency of 99.6% can be achieved, saving you even more money on your water heating bills.
To ensure there’s always hot water on cloudy days or at night time, the SolFlow solution allows you to choose between an independent electric or gas booster to ensure a round-the-clock supply of piping hot water.
