NREL Raises Rooftop PV Potential Estimate

Facebook X LinkedIn Email
The U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) said it has used detailed lidar data for 128 cities nationwide, along with improved data analysis methods and simulation tools, to update its estimate of total U.S. technical potential for rooftop photovoltaic (PV) systems. The analysis reveals a technical potential of 1,118 GW of capacity and 1432 TWh of annual energy generation, equivalent to 39 percent of the nation's electricity sales. This estimate is significantly greater than that of a previous NREL analysis, which estimated 664 GW of installed...Read full article

    lidar
    Lidar, short for light detection and ranging, is a remote sensing technology that uses laser light to measure distances and generate precise, three-dimensional information about the shape and characteristics of objects and surfaces. Lidar systems typically consist of a laser scanner, a GPS receiver, and an inertial measurement unit (IMU), all integrated into a single system. Here is how lidar works: Laser emission: A laser emits laser pulses, often in the form of rapid and repetitive laser...
