About Solar photovoltaic panel laying density
We used plant-level data—such as lat/long coordinates, capacity (DC and AC), capacity factor, and fixed-tilt versus tracking—collected for our “Utility-Scale Solar” report series (utilityscalesolar.lbl.gov) to.
Power density declines at higher latitudes for fixed-tilt plants (blue x’s), as lower GCRs are required to avoid self-shading, but trends for tracking.a) Power density declines at higher latitudes for fixed-tilt plants (blue x’s) , as lower GCRs are required to avoid self-shading, but trends for tracking plants (orange circles) are less obvious/intuitive.

Specifically, the median power density (MW /acre) increased by 52% (fixed tilt) and 43% DC (tracking) from 2011 to 2019, while the median energy density (MWh/year/acre) increased by 33% for fixed tilt and 25% for tracking over the same period.
To evaluate the maximum PV power generation, there were two conditions required for calculation: (1) all of the solar panels are laid on the suitable area (2) each panel receives the largest inclined solar radiation calculated at noon of the summer solstice with the best tilt angle.
Researchers in the US Department of Energy’s Lawrence Berkeley National Laboratory (LBNL) have found that utility-scale solar power facilities have increased their panel density by 43-52%, which boosted electricity generation per acre by 25-33%, even as more facilities are coming online in northern locations that receive less sunlight.
This study provides the first major update of utility-scale PV’s power and energy densities in nearly a decade. It is based on a large, nearly complete sample of ground-mounted PV plants larger than 5 MW-AC that were built in the United States from 2007-2019.

5 FAQs about [Solar photovoltaic panel laying density]
Are utility-scale photovoltaic plants affecting land-use impacts?
Abstract—The rapid deployment of large numbers of utility-scale photovoltaic (PV) plants in the United States, combined with heightened expectations of future deployment, has raised concerns about land requirements and associated land-use impacts.
Are solar panels generating more electricity?
LBNL researchers have found that since 2011, utility-scale solar facilities have increased panel density by 43-52%, and electricity generation 25-33%, for single axis tracking and fixed racking systems, respectively.
What is the tilt angle of a solar panel?
Determining the tilt angle Tilt angle tends to be 0° laying PV panels around the equator is more common, because the direct sunlight around the equator is frequent and PV panel can obtain sufficient solar radiation. But tiled PV panels are not suitable for other latitudes.
Can photovoltaic energy be used to power digital devices?
Since digital devices ultimately use low voltage DC (LVDC) power, in a contemporary house full of smartphones, laptops, cameras and other appliances, AC is passed through a transformer-rectifier that converts it into DC. In that sense, photovoltaics-generated energy can be used directly at home to power digital devices at a reduced cost.
What are the advantages of solar photovoltaics?
The other obvious and well-known advantage of solar photovoltaics is that it is capable of producing the direct current (DC). Since digital devices ultimately use low voltage DC (LVDC) power, in a contemporary house full of smartphones, laptops, cameras and other appliances, AC is passed through a transformer-rectifier that converts it into DC.
