3 Free-E Overview - How it Works
When PV panels generate electricity, the production is initially consumed by electrical appliances or devices
in the household that are creating a demand for energy. If the household does not consume all of the energy
produced by the PV panels, the surplus energy will be sent to the grid.
The Free-E uses this surplus photovoltaic energy instead to heat the water in a household water tank, and
therefore prevent this energy from going to waste. The Free-E can divert up to 95% of unused (otherwise
exported) solar PV electricity to an electrical water heating device. This maximises the consumption of self-
generated solar power and minimises the cost of buying energy for domestic hot water. It can be retrospectively
fitted to homes already with solar PV and a hot water cylinder.
