Solar panels can be mounted on elevated racking so they can share space with other land uses, such as parking lots. These can provide shade for cars and reduce additional land use, but considerably more expensive than conventional ground-mounted systems due to the more extensive steel posts, footings and racks, as well as additional labor costs.
Most solar parks are ground mounted PV systems, also known as free-field solar power plants. [51] They can either be fixed tilt or use a single axis or dual axis solar tracker . [ 52 ] While tracking improves the overall performance, it also increases the system's installation and maintenance cost.
An insolation map of the United States with installed PV capacity, 2019. A 2012 report from the National Renewable Energy Laboratory (NREL) described technically available renewable energy resources for each state and estimated that urban utility-scale photovoltaics could supply 2,232 TWh/year, rural utility-scale PV 280,613 TWh/year, rooftop PV 818 TWh/year, and CSP 116,146 TWh/year, for a ...
