Results of a series of tests designed by the National Renewable Energy Laboratory (NREL) and conducted by PV Evolution Labs (PVEL) to measure the performance of various inverter technologies in various shading conditions were published today. The test determined the annual percentage of energy recovered by power optimizers and micro inverters when compared to traditional string inverter systems in shaded conditions.The results indicate that the SolarEdge optimized system generates 2%, 5% and over 8% more energy than traditional string inverters in light, medium and heavy shading scenarios, respectively.The SolarEdge system outperformed all systems in annual energy production demonstrating higher results than the leading micro inverter solution as well. "The SolarEdge system yielded more energy than the string inverter system in all tests. On an annual average, the SolarEdge system recovered 24.8% of energy lost due to shading, while the microinverter system recovered 23.2%," says Matt Donovan, PV Evolution Labs.
