Every time I go the RSPB nature reserve at Leighton Moss I photograph this display. It's helpful in understanding solar power in these latitudes. Here's the previous post from June last year http://wigtonphysics.blogspot.co.uk/2014/06/update-on-solar-power.html so in just over 10 months they have generated 1225 kWh. I now understand that the power = 1.71 kW is irrelevant - it wouldn't power much. But connected to the National Grid, we'd all act like little rooftop power stations. You get paid for the electricity that you generate - it's called the feed-in tariff. If that's still at 14p per Unit, they'd have made about £170. Now if there are maybe 30 million rooftops in the UK, you'd get 42GWh of solar energy a year. I'll need to look up how much the UK actually uses.
