Ground-mount solar is not just for farms. Many suburban Connecticut homeowners choose it for practical reasons:
Large trees to the south are a common issue in CT. A ground array can be sited to avoid shading, while a rooftop system would underperform.
Many CT towns have historic district commissions that prohibit visible rooftop solar. A ground array in the backyard avoids their jurisdiction.
A north-facing roof, a flat roof with drainage issues, or an east/west-only pitch significantly reduces rooftop solar production. Ground arrays face south at optimal tilt.
Installing solar on a roof that needs replacement in 5–7 years means expensive removal and reinstallation. Ground-mount avoids that entirely.
A 10 kW system requires roughly 600–700 sq ft of array space, plus setbacks. If you have a half-acre or more, ground-mount is feasible.
Some CT homeowners simply prefer solar panels not be visible on the roof. A well-sited backyard array can be screened by landscaping.
Ground-mount systems cost more than rooftop — typically 20–50% more. Here is where the premium comes from:
| Cost Component | Rooftop | Ground Mount |
|---|---|---|
| Solar panels (10 kW) | $7,000–$9,000 | $7,000–$9,000 |
| Racking / mounting | $1,500–$2,500 | $4,000–$8,000 |
| Inverter(s) | $1,500–$3,000 | $1,500–$3,000 |
| Wiring & conduit | $800–$1,500 | $2,500–$5,000 (trenching) |
| Concrete footings | $0 | $1,500–$4,000 |
| Labor | $3,000–$5,000 | $5,000–$9,000 |
| Permits | $300–$600 | $400–$800 |
| TOTAL (10 kW) | $28,000–$33,000 | $35,000–$50,000 |
Panels mounted at a fixed angle (typically 25–35° in CT for optimal winter performance). Simple, durable, low maintenance. Best for most residential applications.
Best for: Most CT homeowners — lowest cost, reliable production
A single central pole supports 6–10 panels. Can be manually adjustable (seasonal tilt changes twice a year). Lower ground footprint than racked arrays.
Best for: Tight yards, rocky terrain, aesthetic preference
The array rotates east-to-west throughout the day to follow the sun. Maximizes production but adds mechanical complexity and maintenance. Best ROI at 15+ kW.
Best for: Large systems (15+ kW) where production maximization matters
Connecticut bedrock is close to the surface in many areas, especially in the Connecticut River Valley and along the coast. Ground piers (driven or augered) may hit ledge and require specialized installation. Get a soil assessment before signing a contract.
If your proposed array location is within 100 feet of a wetland or watercourse, you need Inland Wetlands Commission (IWC) approval from your town. This review typically takes 4–8 additional weeks. Your installer can help identify wetland setbacks on your property.
Most CT towns require ground-mount solar arrays to be set back 10–15 feet from property lines, and in some cases from existing structures. Some towns in the shoreline zone have additional restrictions. Always check with your town before finalizing array placement.
Connecticut has more historic districts per capita than almost any other state. If your roof is in a historic district, a ground-mount system in the rear yard — not visible from public ways — typically does not require historic commission approval. This is a major advantage over rooftop solar in towns like Litchfield, Essex, and Old Saybrook.
Some CT towns (especially in Fairfield County) have tree preservation ordinances that regulate removal of trees over a certain diameter. If your ground array requires tree removal, verify with your town before proceeding.
Ground-mount solar in Connecticut qualifies for the same RRES (Residential Renewable Energy Solutions) netting tariff as rooftop solar, provided your system is under 25 kW and serves your home. Key terms:
Connecticut does not have a state solar rebate. The RRES netting credit, combined with the sales tax exemption (6.35% exemption on solar equipment) and property tax exemption (permanent exemption for residential solar), represents the bulk of CT solar incentives.
Rooftop solar is constrained by your usable roof area, orientation, and shading. A ground-mount array can be:
RRES sizing cap reminder: CT RRES limits system size to 125% of your prior year annual consumption. If you plan to add an EV or heat pump soon, size your system for projected future usage — tell your installer before they finalize the design.
Connecticut averages 40–50 inches of snow annually across most of the state (more in Litchfield County). Rooftop panels are unreachable after a storm — you lose production until snow slides off naturally, which can take days or weeks in cold snaps.
NuWatt Energy designs and installs ground-mount solar systems throughout Connecticut. We handle soil assessment, wetland review coordination, permitting, and Eversource or UI interconnection — all included.
