Abstract:
Around the world, large-scale bifacial photovoltaics (BPV) modules are increasingly being used to generate clean electricity, given the cost of manufacturing is becoming comparable to conventional monofacial PV modules. BPV, when installed vertically, can still produce high levels of electricity by collecting radiation on the front as well as on the rear side. This paper assessed the renewable energy generation potential of vertical BPV plants along the central reservation of UK motorways. These installations maximize the utility of road space while minimizing land consumption. The feasibility of BPV systems for different segments of a motorway case study in the UK were modelled to calculate energy yield, the levelized cost of electricity (LCOE), payback period, and net present value. The LCOE of a medium to large-scale system was 10–11 p/kWh, 60% less than that of a small-scale system. The payback period for medium to large-scale systems was found to be 6 years, whereas for small systems, it was 10 years. The paper further discussed the challenges and opportunities associated with installing BPV panels on motorways with guidance on the types of locations which are likely to be most successful for future full-scale installations.
