[QUOTE="ProDave, post: 525593, member: 6969"] Agree. WITH BATTERIES you can use your generated PV for better uses to power stuff that you would be using anyway in the evening, saving your electricity import price, now typically 27p per kWh. PV diversion to an immersion heater is really for people without batteries. Then you have the choice of use it or lose it (export it) And doing that and time shifting the big loads, I can self use almost all I generate. So for me, each time I look at fitting batteries, the sums don't work, as the batteries will only enable a "better" use of the power from the PV than water heating, and for that they don't yet make economic sense. Regarding the 5.5p export. In order to be able to claim that, you must have an MCS install, and the extra that costs to a PV system vs a DIY install would never pay for the small export payments you can claim. To put that into perspective, the small amount I have exported in the last 3 years would have earned me a massive £16.50 I won't lose sleep at the loss. [/QUOTE]
