A new report published by the International Energy Agency’s Photovoltaic Power Systems Program (IEA PVPS) outlines the need for PV module standards and testing to focus on ‘energy rating’ – an estimate of actual performance in a variety of climate conditions, rather than nominal power output or efficiency. The report finds that the IEC and other standards bodies are already beginning to make encouraging moves in this direction, but more work, and more data, are needed to make the most out of this approach.
The world had more than half a terawatt of PV generation capacity at the end of last year as emerging solar markets picked up the slack caused by Beijing’s subsidy about-turn to the tune of a 20% rise in installations outside China.
In a new report, the association states that urgent action is required for, among other issues, the improvement of solar generation forecasts, the exploitation of storage systems, and the reduction of minimum operation and start-up times for both existing and new thermal and hydro generators.
The world’s cumulative PV capacity had surpassed 303 GW at the of 2016, according to a report from IEA PVPS. Globally, solar power is now able to cover approximately 1.8% of power demand.
