We based our estimations on the Europa Solar Calculator which estimated that they would generate around 2,700 kWh per year.
Annoyingly, we haven't been able to hook the panels up to the Internet, so I can't get daily readings. So, every three months we have to manually look at the meter. Last month, after a year of operation, it stood at...
That totally busted through our estimations!
The last three months saw them generate a whopping 489 kWh.
Now, I'm not sure if the weather this year has been particularly favourable, and I've no idea if next year will be as sunny, nor do I know whether the panels effectiveness will degrade over time.
But, still, that's pretty damn impressive!

The current Feed-In-Tariff set by the Government (and guaranteed for 25 year to rise with inflation) is around £0.454 per kWh generated, plus £0.03 per kWh exported to the grid. It's assumed that 50% of what you generate is exported.
That means, over a year, our solar panels have earned us, roughly £1,500! (The price has recently gone up, so it's not a straight calculation.)
That's comfortably ahead of our expectations of £1,200 per year. It also doesn't take into account energy savings - we don't live there - so with the recent energy price rises, that's a decent saving for the tenants.
I'm really looking forward to seeing how they perform over the next twelve months.
If you'd like solar panels installed, I can highly recommend Sunny Future Solar.
