Independent solar economics
A practical, unbiased guide to going solar — straight answers on cost, savings, financing, and whether it's worth it. Use current rate data as context, then enter documented household and project evidence.

02 / Orientation
Learn the physical system or evaluate the financial decision. Both paths lead to focused explanations without a sales handoff.
