The short answer
Community solar = subscribe to a remote farm for 5-15% bill credit, no upfront cost, cancel anytime. Best for renters and shaded roofs. Rooftop solar = $18-36K upfront, 50-90% bill reduction, 25-30 year lifespan, 13-15 year payback in 2026. Best for homeowners with south-facing roofs and 10+ year horizons.
Community solar lets you subscribe to a remote solar farm and receive bill credits proportional to your share — without putting panels on your roof, paying upfront, or worrying about roof orientation. Rooftop solar puts panels on your house, requires capital investment of $18-36K, and produces 50-90% bill reduction. Both are real renewable options, but they fit different customer profiles.
Community solar — subscribe, do not own
Community solar is a subscription model. A third-party developer builds a solar farm on shared land. The kWh produced is allocated to subscribers proportional to their share. Your utility credits your bill at retail rate (or close to it) for the kWh allocated to you.
Cost structure: typically a 5-15% discount off your normal utility rate. No upfront cost. No equipment on your property. Cancel any time (most contracts have 30-90 day notice).
Best for: renters, condo owners, homes with shaded or unsuitable roofs, capital-light households who want renewable supply without the commitment of rooftop. Available in 22 US states with community solar legislation.
Rooftop solar — invest, then enjoy
Rooftop solar puts photovoltaic panels on your house, an inverter in the basement / garage, and (optionally) a battery for backup power. Generation offsets your grid draw kWh-for-kWh.
Cost structure: $18,000-$36,000 upfront for a 6-10 kW system. 13-15 year payback in 2026 (federal credit expired). Lifespan: 25-30 years. Total savings over system life: $25,000-$60,000 typical.
Best for: homeowners who plan to stay 10+ years, have south- or west-facing roofs without major shading. The solar-roof-suitability-orientation and solar-panel-cost-by-system-size guides cover sizing and roof assessment.

Decision matrix
Community solar wins for: renters, condo owners, shaded roofs, north-facing roofs, capital-light households, households planning to move within 5-7 years.
Rooftop solar wins for: stable homeowners with south- or west-facing roofs, $25K+ to invest, 10+ year horizon, desire for maximum bill reduction or backup capability.
Both can be combined: subscribe to community solar for current home; install rooftop when you buy your forever home.
Recap
Bottom line
Community solar and rooftop solar are both legitimate paths to renewable electricity, but they fit different customer profiles. Community solar (subscribe to a remote farm, 5 to 15 percent bill credit, no upfront cost, available in 22 US states) works best for renters, condo owners, shaded-roof homeowners, and households planning to move within 5 to 7 years. Rooftop solar (own panels on your house, 50 to 90 percent bill reduction, $18,000 to $36,000 upfront) works best for stable homeowners with south- or west-facing roofs and 10+ year horizons.
For households who want renewable supply without committing to either, voluntary RECs through your competitive supplier (the how-to-buy-100-percent-renewable-electricity guide) provide the simplest entry point.
