Solar panels work fine. Heat pump is an air to air type and works very well. U have to clean the filters every week. takes 10mins.
My original 'electricity' meter went backwards when the panels were exporting. the SSE were informed and they fitted a digital meter.
Now I believe the digital meter cannot distinguish between import and export and my cost of electricity is increased!
Because of this I am thinking of installing a Wattson Solar Plus energy monitor. This it claims will tell me when I am exporting and when importing. + give me a record.
