Enphase Claims Microinverter Outperforms NREL Estimates: In a shaky global solar market, leading microinverter...

In a shaky global solar market, leading microinverter manufacturer Enphase Energy keeps firing on all cylinders. Earlier this year, Enphase filed an S-1 , began raising another round of VC funding , and released a new line of 3rd generation microinverters that aim to increase performance while cutting manufacturing costs. Today, Enphase released results from a field performance study demonstrating that Enphase installations, on average, perform 8 percent higher than the PVWatts calculator predicts. PVWatts, a PV performance calculator developed by the National Renewable Energy Laboratory (NREL), is popular among residential and small commercial installers, though it is usually cast aside in favor of more robust simulators like PVSyst and PV*Sol for larger systems. The field performance data was gathered from 143 Enphase installations spread across California and eastern st...
