Assume that a typical PV system in the UK will generate 950 kWh/kWp/year and will cost £1.40/Wp to fully install the system. If electricity costs 20.0p/kWh, and you are paid 5.0p/kWh for any electricity exported to the grid, please answer the following questions: 1. What size PV system can be best fitted on to the available roof area? 2. What inverter or combination of inverters would you recommend and why? 3. What would be a simple payback period in years for your proposed system and what assumptions have you made? Total annual electricity 3100 kWh consumption Available area for PV on the roof (m²) 11.7m x 3.2m- 37.4m2
