Cost of Manufacturing Solar
Panels Is Projected to Continue Falling
The cost of manufacturing solar panels is dropping more quickly than previously predicted, putting solar energy on course to meet 20 percent of global energy demand by 2027, according to Oxford University mathematicians, who developed a new forecasting model
. By contrast, the International Energy Agency’s predictions are far more conservative, stating that by 2050, solar panels will generate just 16 percent of global energy demand. The Oxford researchers' model predicts solar panel costs will continue to decrease 10 percent a year for the foreseeable future. Their model draws on historical data from 53 different technologies. The findings should help refute claims that solar PV cannot be ramped up quickly enough, said Oxford's Doyne Farmer, who co-wrote the paper. “We put ourselves in the past, pretended we didn’t know the future, and used a simple method to forecast the costs of the technologies,” he said.
