Solar panels

We went to the RSPB's nature reserve at Leighton Moss in Lancashire. They have this display up about the solar panels on the roof. They have generated 8749 kWh of electricity in about six and a half years. At, say, 10 pence per kWh that's saved them over £800. I wonder how much they cost to install? The power is very low: 0.13kW on a bright day in December would do some low energy light bulbs. I'm also wondering how this system works. Does it mix with the mains electricity or does it run on a separate circuit?
