I've been so distracted lately, I haven't been keeping up..
Today, the clouds are rolling in again.. So, my hotwater tank will need to be heated by the grid (heat pump)..
On sunny days during the cold weather, the PV does the whole job. And the heatpump is our back-up..

Does your Greenhouse have a back-up heat source, in case of 20 dark days?
