Ground-Mount Solar: Costs, Land Requirements & How It Works (2026)
Ground-mount solar puts panels in your yard instead of on your roof. Most installers offer it. The real question isn't whether it's possible — it's whether you have the land, and whether the siting works. Here's the real math, not a sales pitch.

Do You Have Enough Land?
For a typical 7–8 kW ground-mount array you need roughly 500–700 sq ft of open, unshaded ground — a patch about 25 ft by 25 ft. More system means more space, and it scales close to linearly:
| System size | Panels (approx.) | Open ground needed |
|---|---|---|
| 6 kW | 14–16 | ~400–550 sq ft |
| 8 kW | 18–22 | ~550–750 sq ft |
| 10 kW | 24–28 | ~700–950 sq ft |
Two things matter more than raw acreage. Orientation and tilt: south-facing, tilted at roughly your latitude, gives the best year-round production — and with a ground mount you get to choose, instead of being stuck with whatever direction your roof faces. Shading: a half-acre with trees to the south can be worse than a small clear patch. Unshaded from about 9 a.m. to 3 p.m. is what counts.
How Far From the House Can It Be?
This is the single most common question we get, so here's a proper answer. The constraint is voltage drop — the longer the wire run, the more energy is lost as heat along the way. Installers design to keep that loss under roughly 2–3%. The fix for a longer run is simply thicker wire, which costs more per foot. It's a solved engineering problem, not a dealbreaker.
- 90 ft is routine. No one blinks at that.
- 200–300+ ft is where upsizing the conductor starts to add real cost and change the math.
But distance isn't the main cost driver — trenching is. You're digging a trench from the array back to the house to run conduit underground, and what's in the ground decides the price. Trenching runs roughly $5–$12 per linear foot in normal soil; soft, sandy soil is at the low end, while hard clay, tree roots, or ledge rock push it up fast. Crossing a driveway means boring or cutting under it — directional boring runs about $10–$30 per linear foot for that stretch. Route matters: going around an obstacle can be cheaper than through it. A 150 ft run across a sandy lawn is a very different bill from a 150 ft run that hits rock and crosses a paved driveway — even though the distance is identical.
What a Ground Mount Actually Looks Like
People sometimes assume the marketing photo is staged — "do you actually set up on the lawns like this?" Yes. Here's the real anatomy:
- Racking frame on driven steel piles or concrete footings, engineered for your local wind and soil.
- A few feet off the ground at the low edge, tilted south at roughly your latitude — high enough to walk under or trim grass beneath.
- Conduit runs underground from the array back to the house, so there's no cabling strung across the yard.
Ground Mount vs. Roof Mount
| Ground Mount | Roof Mount | |
|---|---|---|
| Cost | Several thousand more (footings, trenching, permits) | Lower |
| Tilt | Optimal — you choose the angle | Whatever your roof is |
| Maintenance | Easy to reach for cleaning / snow | Ladder or contractor |
| Operating temp | Cooler air underneath = slightly better output | Runs hotter |
| Roof penetration | None | Yes |
| Re-roofing | No teardown needed | Panels must come off (~$2,000–$5,000) |
| Space | Uses part of your yard | Uses your roof |
The short version: ground mount costs more up front but gives you better siting, easier maintenance, and no entanglement with your roof's lifespan.
Do You Have to Own the Property?
Yes — for both roof and ground mount. A solar system is a 25-year asset physically attached to real estate. Whoever finances it — a lender, or the company that owns a leased/PPA system — protects their investment by filing a UCC fixture filing or a lien tied to the property. You can't put that kind of long-term encumbrance on land you don't own.
Ground mount adds a few wrinkles worth flagging early: land and home owned by different people (common with family parcels), trusts or joint ownership where everyone on the deed usually has to sign, and easements or deed restrictions that limit structures on part of the lot. Renting? You generally can't put in your own system, but community solar — where available in your state — lets you get solar savings without owning anything.
Permits, Setbacks, and Zoning
Most zoning codes treat a ground mount as a structure — like a shed or a deck — which means it's a separate permit track from a rooftop system. Setbacks: towns require the array to sit a certain distance from your property lines, and that distance varies locally; it can rule out a spot that otherwise looks perfect. Wind load: exposed sites like ridgelines or open fields sometimes trigger an engineering review. The best move is to ask your town's building department early, before the system is designed around a spot you can't actually use.
Ground-Mount Solar for Manufactured / Mobile Homes
If an installer told you they "don't do mobile homes," they were almost certainly talking about the roof — and ground mount often sidesteps the whole problem. Installers decline manufactured-home roofs for a few reasons: lighter truss construction (panels add roughly 3–4 lbs per sq ft plus wind loading, and many manufactured-home roofs aren't built for it), titling (manufactured homes are often titled as personal property rather than real property, which complicates financing), and metal roof seams that are hard to attach to without risking leaks.
A ground mount avoids all three — the panels never touch the home. The catch is the same as for anyone else: you have to own the land the array sits on. If you own your lot, ground-mount solar on a manufactured home is very doable.
When Ground Mount Doesn't Work
We'd rather tell you no than sell you a bad project. Ground mount is the wrong call when:
- You don't have enough unshaded open land.
- The soil is ledge rock or otherwise difficult, making trenching and footings expensive.
- Setback rules leave no viable spot on the lot.
- You don't own the land.
- The run is so long that conductor upsizing dominates the cost.
- The local utility has interconnection limits — some rural co-op feeders cap how much solar they'll accept.
If any of these apply, a good installer will tell you before you spend a dollar. So will we. Not sure if solar pays off for you at all? Start with Is Solar Worth It in 2026? or the 2026 cost breakdown.
Frequently Asked Questions
How much land do I need for ground-mount solar?
Roughly 500–700 sq ft of open, unshaded ground for a typical 7–8 kW system — about a 25 by 25 ft patch. Bigger systems need proportionally more.
How far from the house can ground-mounted panels be?
Farther than most people expect. 90 ft is routine. Past 200–300 ft, thicker wire and trenching costs start to add up. Distance itself is rarely the dealbreaker — trenching conditions are.
Is ground mount more expensive than roof mount?
Usually yes — typically several thousand dollars more, because of footings, trenching, and a separate permit. In return you get optimal tilt, easier maintenance, and no roof penetrations.
Do I need a permit for ground-mount solar?
Almost always. Most towns treat it as a structure with its own permit track and setback rules from your property lines. Ask your building department early.
Can I get ground-mount solar on a mobile home?
Often yes — if you own the land. Ground mount avoids the roof-strength and titling issues that lead installers to decline manufactured-home rooftops.
Do most installers do ground mounts?
Yes. Ground mount is a standard offering. The limiting factor is your land and siting, not whether installers will do the work.
Does ground mount need more maintenance?
Not more — if anything it's easier. Panels are at ground level, so cleaning, snow removal, and service don't require a ladder or roof access.
