Frequently Asked Questions
What is community solar and how does it work?
Community solar allows you to subscribe to a portion of a shared solar farm. You receive credits on your electric bill for the energy your share produces, typically at a 5-20% discount. No panels are installed on your property, and you can usually cancel with 30-90 days notice.
How much can I save with community solar?
Most community solar programs offer 5-20% savings on the portion of your bill covered by solar credits. For a $150/month bill with 90% offset and 15% discount, that's about $20/month or $240/year in savings with zero upfront cost. Savings grow as utility rates increase.
