Path-Q Solar
When does limited roof space justify considering a ground-mounted solar assessment?
Answer
Consider a ground-mounted assessment when the roof cannot provide enough suitable, unshaded area for your goals or has condition, orientation, access, or structural constraints, and the property has a viable location for a ground array. Ground mounting can improve orientation and access but introduces land-use, foundation, security, vegetation, drainage, and connection considerations.
Key points
- Compare usable roof capacity with the system size needed for your electricity goals.
- Assess ground area for sun exposure, slope, drainage, soil, access, setbacks, vegetation, and future land use.
- Consider whether ground mounting offers easier maintenance or expansion than the roof.
- Include trenching, foundations, racking, fencing, landscaping, and electrical connection in the scope.
- A ground array may be unsuitable if it conflicts with planned construction, agriculture, views, or property use.
What it depends on
- Roof usable area, shading, condition, and structural suitability
- Available ground area and site conditions
- Desired production, system size, and future expansion
- Access, security, drainage, interconnection, and land-use requirements
Risks and trade-offs
- Ground mounting may cost more and require more site work than a roof system.
- It can use valuable land and be more exposed to damage, vegetation, animals, or unauthorized access.
- Permits, setbacks, easements, zoning, environmental constraints, and utility requirements are location-specific and must be verified.
Information you may need
- Roof measurements, shade, condition, and structural limitations
- Ground-area dimensions, slope, drainage, access, and future use
- Desired production and expansion plans
- Local land-use, permitting, setback, and interconnection requirements
Your next step
What to do next
Ask an installer to compare a roof-constrained design with a ground-mounted concept, then verify site, land-use, permitting, and utility requirements before paying for detailed design.
