Utility Scale PV Solar Site Specification/Audit Form
Date: December 2014
Solar Photovoltaic Ground Mounted System
Site Worksheet
Site Specifications to Consider:
a. Site dependent variables
i.
avoid tree lines or shading obstructions (southern, eastern/western boundaries)
ii. location of inverter can vary depending on interconnection point, type of inverters used and
shape of parcel being considered
iii. topography, which is geography dependent, would prefer flat or sloped to south or southwest
(typical tolerances for pier foundations is approximately 7-8% percent east to west)
iv. subsurface, which is also geography dependent, keep in mind that approximately 600 piers +/pending site specific geotech report and pile pull test results (c channel) driven into the ground
6 to 12 feet are needed for a 1 MW system
v. surrounding terrain assumptions (tree clearing, setbacks, ROW/easements, access to site, POCC
location, fencing requirements)
b. Ground coverage ratio can be affected, depending on site specific factors (e.g., more tilt requiring
greater row to row spacing, , off axis orientation to due south, shading obstructions, shape of
parcel) can increase acreage or decrease ground coverage ratio
