Extra Panels or Fuel Pump
Around three years ago I had a 7.8kw system installed with a 5kw battery. I’m very happy with it and am considering adding around 20 ground mounted panels to it. I’m in Ireland so would need to apply to the electrical supplier for 3 phase capabilities.
I’m wondering what makes more sense for me to do though. I have an airtight house so wondering if I should pump the money into replacing my oil heating system or pump the money into ground mounted panels.
Anyone done similar?
