DTI provides research funding to companies developing photovoltaic (PV) cells through the DTI Technology Programme. The overall research budget for emerging energy technologies is £20 million per annum.
Funding for installation of the technology is through the PV Major Demonstration Programme and grants go to householders and public organisations, not direct to the companies installing the technology.
The Renewables Innovation Review, published by DTI and The Carbon Trust in February 2004, recommended continued support for research and development into next generation PV technologies. The report stated that PV was not expected to be fully economic compared to retail price until post 2020; however next generation solutions could bring this forward.
The Renewables Innovation Review estimated that the potential contribution of PV towards reducing carbon emissions was 3 Mt by 2050 (total contribution from renewable energy aspiration of 20 Mt).
