Path-Q Solar

Is a ground-mounted solar array a better option than a shaded roof for my property?

Answer

It can be, when the ground site has substantially better sun exposure, suitable soil and drainage, enough space, and acceptable installation and maintenance costs. A shaded roof may still be preferable if ground work, land use, trenching, security, or permitting makes the ground mount disproportionately expensive or impractical.

Key points

  • Compare expected production from each location rather than comparing panel count alone.
  • Ground mounts can offer easier access, flexible orientation, and roof preservation.
  • They require land, foundations or supports, wiring to the building, and protection from damage or vegetation.
  • The best option may be a smaller ground array, a roof array, or a combination.

What it depends on

  • Shading and solar exposure at the roof and ground sites
  • Available land, slope, soil, drainage, and access
  • Trenching distance and electrical design
  • Roof condition and structural suitability
  • Land-use, permitting, and security constraints

Risks and trade-offs

  • Ground mounts can disturb land and add civil, trenching, fencing, or vegetation-management costs.
  • A shaded roof may produce less energy but avoid land-use and site-preparation costs.
  • Ground equipment may be more exposed to weather, animals, vehicles, or unauthorized access.

Information you may need

  • Shading analysis for both locations
  • Ground survey and soil, drainage, and access information
  • Roof inspection
  • Production and total-cost estimates for each option

Your next step

What to do next

Request comparable roof and ground-mount designs using the same energy goal, showing production, site work, wiring, maintenance, and total cost separately.
