Hopefully the booster will be fixed some time in early June. The system works brilliantly when the sun is out but there hasn't been much of that lately. The only plus is that not having the booster working has saved us heaps on our power bill. So, so much for solar when it doesn't work and unless you have experienced that then most of these Greenies haven't a clue what they are talking about or for that matter what they are in for! You can bet most don't even have solar, whether it be for electricity or for that matter hot water. We have solar roof panels as well which feed the grid and they for the last 5 months have contributed bugger all as far as electricity is concerned i- totally useless and of no benefit what so ever! This morning the sun came out for a while and pushed the water temperature up to 29C and that'll be the maximum now as it's clouded over again. If any of Albo's minders read this could you pass it onto the Dumbo!!! But I bet you won't!!!
