What support is there for PV?

FiT Generation Tariff: 13p/kWh

(FiT - Feed in Tariff)

Government support for higher tariff for community schemes

Sell electricity:

Exported electricity to supplier

Below market rate electricity to roof owner.

Hasn’t FiT dropped?

Yes: FiT has dropped significantly

ROI’s were much higher than expected

(15-20%)

Reduction in cost of PV means FiT level is

right for ROI’s of 8-10%Moore’s Law:- Computing power doubles every 2 years, costs half

Benefits of solar PV
