.The absolute energy yield (EY) of PV modules is defined in watt hours (Wh). Because of the diferent eficiencies and designs of PV modules, it makes sense to calculate the specific energy yield in watt hours per watt peak (kWh/kWp), by dividing EY by the nominal power PSTC; this allows
r 1% of energy yield, which could be achieved by choosing capable PV modules. Besides the chance for investors to maximise their net profit by considering the energy yield performance, this relation also bears a certain investment risk for the PV industry if the long-term performance is lower than expect d, and if
.Energy yield performance as a key factor for the return on a PV invest-mentConsider a PV power plant with 100MWp nominal power (for STC) at a location with a moderate specific energy yield of 1,500kWh/kWp and a levelised cost of electricity (LCOE) of US$100/MWh; this means US$150,000 extra revenue for each per cent of additional ener
