The PV solar array generates electricity which is used in real-time within the building, with any excess energy being exported to the grid.
On buildings where hot water is stored in tanks a Solar PV Hot water heating system may be installed where it smartly controls and adjusts the level of energy flowing to your immersion heater in line with the export levels as they rise and fall.
Water is heated over the day using just the free solar energy. In summer, this may deliver all the hot water your home requires; at other times, you may need to top up using your usual heating system or use the built-in Boost and Timed functions.
There are a number of these Solar PV Hot water systems on the market e.g. Marlec Solar IBoost
