These serve overlapping but genuinely different needs — one is ownership, the other is a subscription. The right choice depends on what you're actually optimizing for.
Ownership versus subscription is the core difference
Rooftop solar is a long-term asset you own (or finance) that adds value to your home and can qualify for ownership-based incentives. Community solar is a subscription to a share of an off-site array's output, typically with no upfront cost and bill credits proportional to your share — but no equipment ownership, no direct incentive eligibility, and credits that depend on the program's terms continuing favorably.
Who rooftop solar fits best
Homeowners planning to stay long-term, with a roof suited to solar (good orientation, minimal shading, adequate condition) and access to financing or cash for the upfront cost, generally see the best long-term value from ownership — see the solar ROI calculator for what that typically looks like.
Who community solar fits best
Renters, homeowners with unsuitable roofs (heavy shade, poor orientation, structural issues), or anyone wanting solar's savings without a long-term commitment or upfront cost are better served by community solar where it's available. See our renter's guide for more on this option specifically.
Savings comparison isn't always straightforward
Rooftop solar's savings compound over decades of ownership once the system is paid off; community solar's savings are typically a modest, ongoing discount with no ownership payoff point. Over a very long time horizon, rooftop ownership often wins financially for those who can pursue it — but community solar's zero-commitment, zero-upfront-cost model has real value for those who can't or don't want to own.
Frequently asked questions
Can I have both rooftop solar and a community solar subscription?
Not typically in a way that makes financial sense — community solar credits are meant to offset a bill that rooftop solar is already reducing, so most people choose one or the other rather than both simultaneously.
Does community solar require a long-term commitment?
Terms vary by program — some allow cancellation with notice, others have longer commitment periods, so review the specific subscription terms before enrolling rather than assuming full flexibility.
