How much solar yield can we expect to realise on our assets?

On a standard roof we can fit between 15-18w/sq ft. A 50,000sq ft building can support up to 900kWp of solar. This will produce between 751,000kWh in the North of England and 913,000kWh in parts of the South. Assuming power costs 14p/kWh the system will realise savings of between £105,140 and £127,820 per annum rising in line with energy price increases.
