The Energy Department's National Renewable Energy Laboratory (NREL) has gathered and analyzed data for more than 30,000 solar photovoltaic (PV) installations across the United States to better understand how interconnection regulations align with actual project completion timelines. The findings indicate that interconnection process delays are common, and can range from several days to months. Streamlining the application review and final authorization processes can ultimately benefit utilities and solar consumers by reducing the time and cost associated with going solar.

NREL has teamed with Pacific Gas and Electric (PG&E) and Efficient Drivetrains Incorporated to evaluate the performance of a unique Class 5 plug-in hybrid electric bucket truck. The innovative utility vehicle is equipped with batteries and an electric generator that can export up to 120 kW of power—enough to power a neighborhood while repairs are being made by electric crews. NREL test results will help PG&E fine-tune the design of such vehicles before expanding their use.

Two new reports from the Energy Department's National Renewable Energy Laboratory (NREL) examine the economic options customers face when deciding how to finance commercial or residential solar energy systems. NREL analysts found that businesses that use low-cost financing to purchase a photovoltaic (PV) system and homeowners who use solar-specific loans can save up to 30 percent compared with consumers who lease a PV system through a conventional third-party owner.
