Guess its the minimum the builder could install to benefit from government incentives. No feed in either, apparently tariffs so low nowadays its no longer worth it. Big hot water tank so that will be useful dump of excess power although not sure what programming is possible.

I've experience of pv power generation on a sailing yacht having installed 2 x 150 watt panels myself hooked up to mppt controller, but home systems will present a new learning curve for me.


Richard,
if the move goes ahead then let me know if you need the details of our auto switch system to heat the water. Our from memory kicks in once we start exporting over 250W. The house background usage on fridges etc is around 100-150 W
