Ground mount installation

Completed 1/2011
Installed by Semper Fidelis Construction

System Details:

  • 17.6 kW
  • 72 solar panels
  • 245 W mono Sunmodule™ solar panels
  • 3 SMA inverters

System Overview:

  • This project was very challenging with the multidirectional hill azimuth (from 90 degrees true to 150 degrees true) and the multiple slopes on the hill (from 20 to 35 degrees).
  • The racking height was increased on the down-slope side of the hill to find the “sweet spot” of solar production by optimizing azimuth and tilt.
  • All three arrays have a slightly different azimuth and tilt, providing good year round production.
  • This was a turnkey project; all landscaping, engineering, surveying and construction was performed as part of the contract.
  • The customer is ecstatic that this project is outperforming all estimated solar production calculations.
