Solar Energy Supply in the UK Andrea Finegan March 2010
Types of Solar Uses �Grid-connected domestic systems �Grid-Connected power plants �Off-grid systems for rural electrification �Off-grid industrial applications �Consumer goods
Solar Thermal FLAT PLATE AND EVACUATED TUBE COLLECTORS
Solar PV TYPES OF CELLS (EFFICIENCY) • CRYSTALLINE SILICON (12 -17%) • THIN FILM (5 -13%) • CONCENTRATED PV (20 -30%) • FLEXIBLE
Benefits � PV emits 21. 65 g CO 2/k. Wh compared to 900 g/k. Wh for conventional thermal power � Energy payback between 1 and 3. 5 years � For every MW of PV capacity 7 -11 jobs are created compared to 3 for wind and 1 for coal & gas � Production costs falling 6% p. a. � Grid parity expected in 2013 Domestic 2018 Commercial 5
Non-Domestic Public Buildings Commercial Buildings Ground Arrays
Assumptions for Projections Maximum Technical 266 TWh Potential less Constraints on distribution Limitations on land/building use Practicable Potential Economic potential based on price 37 TWh 0. 5 TWh (Boyle, 2004)
