Title: IV.a Solar PV Costs Content: h1 Technologies costed in this sector * Distributed Solar PV - Please click on: Solar PV Cost Data h1 Costs Methodology h2 Methodology used The user defines the number of distributed Solar PV panel to build. Once the trajectory is set by the user, the number of plants to be built are defined. Investment costs are a function of new build and operating cost are a function of the number of plants operating within that time period. We assume panels are retired after 25 years and the cost of replacement is included. Please see 2050 Methodology for a full description of the costs approach in the Calculator. h1 Technical Assumptions * Lifetime = 25yrs * Efficiency = Capacity factor = 10% * Input Fuel = Solar General Comments Mike Knowles MIMechE - Lowest costs £/kW from EY/Arup/MML 2010 range from 3640 down to 2030 1091–3016 & 2050 383–10231. These lowest costs appear very optimistic for the UK. Costs such as inverters, wiring, controls and installation including structural reports must be >£1000/kW. Lowest reported capital cost from Germany at present appears to be £2500/kW Agree 10% capacity factor for UK as number of hours sunshine in UK is around 1700 compared to sunnier southern European countries reportedly 2700 hours. At present it seems unlikely that UK can achieve <30p/kWh (£300/MWh)FIT, still very expensive compared with onshore wind and nuclear at <10p/kWh (<£100/MWh. h1 Phase I Admin 2050 Costs team lead - Michael Clark Working-level analyst - Henry Shennan, Ben Marriot (DECC) Senior analyst - Sam Thomas, Rocio Concha User: Knowlesmichael2 Picture updated at: Signed off by: Signed off at: |
