22/4/10 - The sun is shining, the days are getting longer and customers are reporting great figures from their panels. We have a system in Warwickshire that made 19kWh in one day.  This means £7.85 from the FIT, 24p from the export tariff and about £2 saved from avoided costs of importing electricity to run the house.  This equates to over £10 return in one day.
