This solar farm was built onsite at the Lawerence Livermore National Lab and completed in late 2016. The 3.3 MW fixed-tilt solar photovoltaic facility represents one of the largest US Department of Energy and National Nuclear Security Administration solar energy deployments at the onsite facility. This 10-acre solar farm produces 6,300 megawatt-hours, enough to power roughly 1 million residential homes. This Change Detection map includes: Before: Lidar which Hivemapper provides for about 30% of the United States. After: Imagery collected in Aug 2019 from a Cessna aircraft flying at roughly 750ft above ground level that was then transformed into a 3D map and accurately georegistered. This map was made from images collected with a Nikon D850 and 18mm Carl Zeiss Milvis lens mounted to a Cessna 182RG with a SkyIMD aerial pod.
