SOLAR POWER 55 energetica INDIA- Jan-Feb_2021 Monthly GHI&DHI data In the above locations, DNV GL com- pared the BOS costs and LCOE of the bifacial dual-glass 166mm-450W mod- ule and 182mm-535W module with the Vertex bifacial dual-glass 210mm-545W module with single-axis 2 portrait in- stallation (2P) tracker, based on fixed 100MW AC capacity, with the same DC/ AC ratio design at the power station. In terms of system design, the projects adopted a single-axis 2 portrait installa- tion (2P) tracker, equipped with a string inverter. The ground cover ratio (GCR) is fixed to ensure the consistent shad - ing on the bifacial module. Such design aims to maintain control over the influence of external factors and system configuration on the same site, to objectively compare costs and LCOE based on different modules. The comparison of the costs of the three tested groups are all based on local equipment, construction and installa- tion, labor costs, grid interconnection fees, costs of operation and mainte- nance, land cost, and financial cost, so that the calculation is consistent, com- plete and objective. The site system is configured as follows: Site system configuration Assessment results:
