Three guides for each market

Start with the local checklist, evaluate the pros and cons, then use the what-to-know guide to challenge your launch assumptions. These resources cover residential solar sales and installation businesses, not home resale. They do not rank markets by demand or promise a profit.

One launch decision, several separate gates

Treat entity setup, licensing, consumer sales compliance, project permits, utility approval and service delivery as separate gates. Each needs a responsible person and documented evidence. A strong sales pipeline cannot make up for unresolved authorization or an uneconomic delivery model.

Use this library to build your questions for authorities, legal and tax advisers, insurers and installation partners. Requirements vary by activity and project. Keep unresolved questions visible instead of calling a general checklist a complete compliance approval.

Homeowner education · Evidence methodology · Site surveys

Make your first project reviewable.

Discuss the service area, project types and site evidence needed for the design handoff.
