What should I have ready?
Start with your ZIP code, a recent electricity bill and your goal: lower bills, backup power or off-grid living. Monthly kWh, roof direction and shading help refine the plan. You can begin with unknowns and review assumptions as you go.
What can I use for free?
Basic Chat, the public solar calculator, Map and energy data are available without a subscription. Creating or changing a saved system through AI and generating saved solar estimates require an account and active subscription.
Is this an installer quote?
No. Estimates show modeled results and assumptions. Before buying, ask an installer to check your property, equipment compatibility and installation scope, and provide an itemized quote.
What happens after my first estimate?
Review the inputs and breakdown in My system, continue the linked conversation, and compare changes. Use your plan to prepare questions for installers; a planning estimate does not arrange an installation.

A good plan shows its working.
Every scenario keeps its inputs and assumptions in view. Published energy references include their location, reporting period and source. You can follow the evidence—and change your mind.
