Solar is looking pretty resilient, according to research from the National Renewable Energy Lab. Now it’s time for international standardization to accelerate and protect investment and performance.
Crunching data from almost 50,000 PV systems pumping out 1.7 gigawatts from 2009 to 2012 — the infamous year of Hurricane Sandy — NREL’s report Reliability and Geographic Trends of 50,000 Photovoltaic Systems in the USA found that 85 percent of them performed 10 percent better than expected. The briefer version? Not even extreme weather events from America’s fearsomely changing climates can make solar panels seem like a dumb investment.
