Should I get a solar lease or buy in Delaware?▼
Buying (with cash or a solar loan) typically provides the best long-term value since you own the system and receive all incentives.

In Delaware, with a 9-year average payback period, buying usually makes financial sense if you can afford the upfront investment.
