Does Solar Increase Property Value?

Updated April 2026 · 6 min read

The short answer: yes. Multiple studies over the past decade consistently find that homes with solar installations sell for more — and faster — than comparable homes without. But the details matter, and the picture for portable/backyard solar is more nuanced than fixed roof systems.

The Data on Solar and Home Value

Backyard Solar Structures and Resale Value

Fixed rooftop solar is the most studied category. But backyard improvements — a solar-powered shed, garden office, or workshop — also contribute to property value, particularly in markets where buyers prioritize outdoor living and sustainability.

A well-built, solar-ready backyard office with power adds functional square footage to a property — which appraisers and buyers factor into value. This is the same principle driving strong ROI on shed additions (see our Shed ROI Calculator).

Portable solar generators are personal property — they don't add assessed value to the property itself. But they do make the property more attractive to buyers who see a functional, energy-independent backyard space.

The Better ROI Story: Operational Savings

Regardless of resale impact, the most immediate financial benefit of portable solar is offsetting ongoing costs: fuel for gas generators, utility extension costs for outbuildings, and electricity bills for detached workshops. These savings are real, immediate, and accumulate every year you own the system.
