The required rate of return (RROR) is a key input in the calculation of levelized cost of electricity, investment decisions and in policy making. The methodology proposed in this paper determines an adequate RROR for grid-connected photovoltaic (GCPV) systems. A calculation of RROR under market conditions has been carried out for four Eurozone countries as well as the assessment of the impact of feed-in-tariff (FIT) support schemes on risk reduction. Moreover, a formula has been proposed to quickly calculate the RROR for GCPV systems based on country risk, risk-free rate and FIT period length if relevant. The methodology can be further applied to other renewable energy sources and can be used to evaluate different support schemes.
