Path-Q Solar
How can I determine whether a second installer opinion is needed for a proposed ground mount?
Answer
Seek a second opinion when the proposal relies on uncertain soil, grading, wind, drainage, structural, trenching, access, or land-use assumptions, or when the project cost and consequences of errors are significant. A second installer or qualified site professional should review the assumptions rather than merely provide another price.
Key points
- Compare foundation approach, soil assumptions, terrain, drainage, and structural loading.
- Check trench routes, utility conflicts, access for construction, and future land use.
- Ask whether surveys, geotechnical information, or engineering are included or excluded.
- Request itemized costs for site preparation, trenching, restoration, and unexpected conditions.
What it depends on
- Ground conditions and topography
- Distance between the array and electrical equipment
- Access, drainage, vegetation, and land-use constraints
- Scope and assumptions in the first proposal
Risks and trade-offs
- Ground mounts can require more civil work, land, maintenance, and permitting than roof mounts.
- Unforeseen soil or trenching conditions can increase cost and schedule.
- A cheaper proposal may omit necessary engineering or site preparation.
- A second opinion adds time and possible assessment cost but can expose material omissions.
Information you may need
- Site plan, survey, photographs, and utility information
- Foundation and trenching assumptions
- Itemized scope and exclusions
- Any soil, drainage, access, or land-use reports
Your next step
What to do next
Obtain an independent review focused on site assumptions and exclusions before committing if any major ground or trenching condition is uncertain.
