  • Thanks for your help. I will contact them on Monday. Our estimated annual usage is 6,112.01kWh from recent bill. We are 30° off south towards west. The kWH/kWp (Kk from table) is 898, no shade. We are in SS9. Just to give you a bit more info. I'm afraid it doesn't mean much to me.:(
  • Also the installed capacity (kWp) is 3.99.

    Popping that info into PVGIS suggests an annual generation guesstimate of approx 3,950kWh, so about 990kWh/kWp. Not bad at all.
    Mart. Cardiff. 8.72 kWp PV systems (2.12 SSW 4.6 ESE & 2.0 WNW). 20kWh battery storage. Two A2A units for cleaner heating. Two BEV's for cleaner driving.

    For general PV advice please see the PV FAQ thread on the Green & Ethical Board.
