Who pays for new home solar generated power ie Feed In Tariff

You divert power that only earns you 5p per unit to heat the your water ( or heating) that you will otherwise have to import at ~19p per unit from the grid. If you do not have gas (we don't) it's a good solution during summer. The wood stove provide more than enough hot water during winter! The diverter maximises your generation benefit as it only diverts excess power. If you have only a small system you may only divert 100W - 500W but over the day this accumulates. In fact it keeps the immersion tank topped up with hot water constantly during the day. Total diversion might be equivalent to 3kW for one hour continuously. Certainly enough to heat a tank. When the immersion thermostat operates the diverter will then divert the excess to the lower priority load. Same principle applies to the Zappi EV charger. Car gets charged via your excess solar instead of using grid. Not much use if your working away from home so a better option is one of the taffifs that have very low rate between 00:00 and 04:00.
