We evaluate power losses and gains resulting from the integration of Rooftop Photovoltaic (RPV) systems into the power grid, within scenarios where the RPV power is either fed back to the grid or consumed “behind the meter”. Power losses resulting from feeding RPV power to the grid are calculated relative to the distance of the site of power generation to the distribution feeder, using GIS data. When the power generated by RPV systems is consumed “behind the meter”, this loss is turned into an equivalent power gain. Early results for 65,536 buildings in Qatar with the assumed integration of a 5kW PV system per building show yearly power losses/gains of 7020MWh. Simulations of residential PV adoption show that these power gains have a mild but distinctive effect, leading to a 1.3% increase in adoption rate. The study suggests that overall power losses/gains are modest, providing mild support for a “behind the meter” PV integration solution.
