Solar PV

Vital statistics:

  • 2.4kW peak
  • Switch-on date: 3/6/10
  • Installers: Ecocetera
  • Our latitude: approx 51.60N
  • Predicted generation: approx 2000 kWh per year. This should give us a return of approx 8% per annum on our capital outlay through the FIT scheme.
    • Actual generation on our first anniversary (3/6/11) was 2517kWh, so a return of approx 10%.

Monthly Generation

  • Generation numbers taken at the end of each month
  • Mean generation per day shown averaged over all time, and for the prior month
  • Target: 5.5kWh per day over the year (to give our projected 2000KWh per annum)
