The physical installation typically takes 1-3 days. However, the full process from contract signing to system activation usually takes 4-12 weeks, with most of that time spent on permitting and utility approval. Timelines vary by installer and local jurisdiction in Montana.

Buying (with cash or a solar loan) typically provides the best long-term value since you own the system and receive all incentives. However, leases and PPAs require no upfront cost and still save on electricity. In Montana, with a 12-year average payback period, buying usually makes financial sense if you can afford the upfront investment.
