Find out how much money and electricity you can generate by using our Solar Cash-back Calculator

You don't need a south facing roof for your home to be suitable for Solar PV (although this will produce the best results); it just needs a degree of direct sunlight. All calculations are based on the average level of UK sunlight per annum and should only be used as a rough guide. If you are unsure of the size and orientation of your roof, contact our friendly advisors.
