This guide covers the costs, ROI, financing, and state incentives for solar on a mobile home. For the structural load, mounting hardware, and permitting side, read installing solar on a manufactured home.
Yes - you can put solar panels on a mobile or manufactured home, and at Accelerate Solar we see this as one of the highest-value solar decisions available to working households. Approximately 22.4 million Americans live in manufactured housing (U.S. Census Bureau, 2021), and these homeowners typically pay some of the highest energy costs per square foot of any residential housing type. Honestly, when I run the math, ground-mount almost always edges out roof-mount. My advice? Pull your HUD Data Plate first, then quote both options before you decide.
Does Roof Strength Affect the Cost of Mobile Home Solar?
Yes, and it's the line item with the widest cost swing. A roof-mounted system on a HUD Windzone I single-wide often needs a $200 - $500 structural review before quoting and may still need reinforcement, while a Windzone II or III double-wide is usually approved without extra work. Ground-mount skips the assessment and adds $1,000 - $2,000. Plan for one of three scenarios:
- Strong roof (Windzone II/III double-wide): $0 added, panels go on the roof.
- Borderline roof (single-wide, HUD minimum): $200 - $500 review, maybe $500 - $1,500 in reinforcement, or pivot to ground-mount.
- Ground-mount default: $1,000 - $2,000 above the roof baseline, no review.
The full structural load math lives in the technical companion guide linked above - read it if you suspect your roof is borderline.
Which Mounting Option Gives the Best Value for Mobile Home Owners?
So why default to the roof at all? You're not limited to it. For many manufactured homes, a ground-mount or carport system is the better choice - lower structural risk, optimal panel angle, and no roof penetrations that could void your HUD warranty. In my experience, the homeowners who paid the extra $1,000 - $2,000 for ground-mount almost never regretted it.
- Roof-mount: Brackets attach to roof rafters, 10 - 15% cheaper than ground-mount. Improper penetrations can void the HUD warranty, so the installer must use an approved method.
- Ground-mount: A racking frame on your lot, structurally independent of the home. Optimal tilt angle and easy cleaning access, but needs lot space and park approval on leased land.
- Carport mount: Panels over a parking area generate power and provide shade at once - popular where roof conditions vary.
- Community solar: If your park bans individual installs, a subscription earns bill credits from a shared offsite array. Availability varies by state.
How Much Does Solar Cost for a Manufactured Home?
NREL's analysis of solar costs in manufactured housing contexts (NREL, 2021) found that system costs run 5 - 15% higher than equivalent site-built installations, reflecting the additional structural assessment, specialized racking, and smaller-batch purchasing that manufactured home work requires.
| System Size | Typical Application | Gross Cost | After 30% Federal Credit |
|---|---|---|---|
| 2 - 3 kW (6 - 10 panels) | Single-wide, low usage | $8,000 - $12,000 | $5,600 - $8,400 |
| 4 - 5 kW (12 - 16 panels) | Double-wide, average usage | $14,000 - $18,000 | $9,800 - $12,600 |
| 5 - 7 kW (16 - 22 panels) | Large double-wide + EV or A/C | $18,000 - $25,000 | $12,600 - $17,500 |
The 30% Residential Clean Energy Credit (IRS Form 5695) applies directly to these costs - and critically, it applies to manufactured homes used as your primary residence regardless of whether you own or lease the land (IRS, 2024). This credit runs at 30% through 2032, drops to 26% in 2033, and 22% in 2034. State programs like California SASH and New York EmPower+ can stack on top for further savings.
Budget reality: Electrical panel upgrades are a common hidden cost. Manufactured homes built before 1990 frequently have 100-amp service. Upgrading to 200 amps costs $1,500 - $3,500 and is often required before a grid-tied inverter can be connected. Ask each installer for an itemized quote that includes electrical work.
How Much Energy Does a Manufactured Home Use?
The U.S. Energy Information Administration's Residential Energy Consumption Survey (EIA RECS, 2020) reports average manufactured home electricity consumption of 1,045 kWh per month - higher per square foot than most site-built homes due to older insulation standards, single-pane windows, and HVAC inefficiency common in homes built before the 1994 and 2000 HUD energy standards updates.
A 4 kW solar system in an average-sun US location (Atlanta, Dallas, Denver) generates approximately 4,800 - 5,800 kWh/year, covering roughly 38 - 46% of a double-wide's annual average demand. Upgrading to 5 kW reaches 60 - 70% offset. Pairing solar with insulation improvements, a mini-split heat pump, and LED lighting can reduce total consumption by 20 - 30% before you size the solar system - dramatically improving your payback period.
When sizing a string, match your panel design to your inverter and service panel capacity - see our explainer on solar panel voltage. On a low-pitch manufactured roof where partial shade is likely, panel-level electronics matter: the SolarEdge P370 optimizer stops one shaded panel dragging down the string, while the Enphase IQ8A microinverter gives independent per-panel conversion for homes where you might expand later. Weight matters too - our best solar panels for 2026 ranking includes weight-per-watt data relevant to HUD-code roof limits.
What State Programs Support Mobile Home Solar?
The federal credit is the floor, not the ceiling. Many states run specific programs targeting solar access for manufactured housing residents:
- California SASH (Single-family Affordable Solar Homes): Provides $3/W upfront incentive for qualifying low-income manufactured home owners
- New York EmPower+: Combines insulation, weatherization, and solar for income-qualifying residents
- New Mexico: Manufactured Housing Improvement Program includes solar grant funding
- Oregon: Manufactured Home Park Program supports community solar access

Summary
Solar is a practical, cost-effective upgrade for manufactured homes. The key step is a roof load assessment - most HUD-code roofs built after 1976 can carry solar after a $200 - $500 engineering check, and ground-mount is an excellent fallback where they can't. The 30% federal Residential Clean Energy Credit applies to owned manufactured homes on owned or leased land, cutting a typical double-wide project from $14,000 - $18,000 to $9,800 - $12,600.
