Community solar vs. rooftop solar: which is right for you?
Last updated 7/15/2020
Community solar power is a great option for renters or property owners who can't (or don't want to) install a solar panel system on their own property.
Community vs. rooftop solar comparison table
The table below examines the main differences between rooftop and community solar. Keep in mind that program criteria and payment models vary between companies, so it's important to understand the advantages and disadvantages of both solar options before making a decision.
|Community Solar||Rooftop Solar|
1. Ownership Model: You may purchase or obtain financing for your share of project under ownership-based programs
2. 'Subscription-based' programs: System is owned by utility or the solar company and you buy electricity at lower cost
|You can own the system, finance it with solar loans, or sign up for a solar lease or PPA|
|Billing and benefit payout|
Billing administered by utility, solar project administrator or combination of both
Benefits delivered via either:
A. Virtual net metering or other monetary credits on monthly electricity bill or
B. Arrangement with community solar supplier whereby utility bill is reduced via solar credits and community solar developer sends separate bill (2 bills total)
Administered by utility
Benefits generally paid via solar net metering credits on your electricity bill, as well as through avoided costs of purchasing electricity from your utility
|Contract duration (for non-purchase options)|
|Variable. Some allow easy entry and exit from programs; others require a long-term contract that's comparable to rooftop solar leases||N/A for solar ownership options; solar lease/PPA, contracts are for 20-25 years|
|Maintenance and parts replacement|
|With both purchase and subscription, maintenance is the responsibility of the project developer/administrator||If PV system is owned, you maintain the system. If leased, system maintenance is responsibility of solar company that owns the PV system|
|When selling the home|
|Typically, community solar benefits are unaffected by relocation if you remain in the same utility service area. Moving out of the utility service area may require an early termination fee||
If owned, systems add to sale price of house
If lease/PPA, may be take over by next occupant (read more)
|Can be built on communal-property (land or even roof) or third-party owned property. However, in most cases project built as ground-mounted on open land for optimal solar access||On roof or elsewhere on property owned by the home or commercial property owner|
|Typical expected life of system is 25-30 years, although some projects may extend longer||Typical expected system life is 25-30 years|
|Property value impact|
|As agreements are between customer and utility, any value associated with system (subscription or purchase) would not transfer to your residence||Rooftop solar has been shown to improve property values|
|Best practice is for projects to be located in proximity to existing grid infrastructure and on otherwise unusable land (e.g. former landfill) to maximize environmental outcomes.
