NREL’s PV Program: Originating as SERI in 1977, today a key component of the U.S. DOE SunShot Initiative, funded primarily through SUNLAMP. 6¢/kWh SunShot 2020 Goal Innova&on for Our Energy Future NATIONAL RENEWABLE ENERGY LABORATORY 5
PV R&D is NREL’s single largest R&D program (~$30M out of ~$300M per year, mainly through SUNLAMP). NREL receives addiGonal funding from EERE’s SunShot IniGaGve, including for grid integraGon, CSP, cost analysis, and soX-cost reducGon.
