Abstract

Long-term monthly average daily solar radiation values on horizontal surfaces at 20 locations in Ireland were used to model the performance of a 1.72 kWp grid-connected PV system. Global solar radiation on horizontal surfaces varied between 865.1 and 1,127.9 kWh/m2/yr with a mean of 947.9 kWh/m2/yr. Annual energy yields varied between 869 and 1,156 960 kWh/kWp with a mean of 960 kWh/kWp. The capacity factor for the PV system varied between 9.9 and 13.2% while the mean was 11.0%. System cost parameters, long-term annual average electricity domestic rate cost escalation were used to calculate the Net Present Value (NPV), cost of electricity production and simple payback period. The potential for greenhouse gas emission reduction was determined by calculating the quantity of CO2 emissions avoided annually as well as the cost of CO2 abatement from electricity generated using domestic scale PV systems in Ireland.
