Solar Estimator gives you a planning-stage cost range to work from before you talk to contractors. Compare any quote you receive against this range and ask for a line-item breakdown if a bid sits well above or below it — that's where pricing games usually show up. In Arlington, TX, most projects fall between $18,498 and $24,199, depending on home size, system type, and the condition of what's already in place. Arlington, TX is a mid-tier market — Labor and permitting costs usually track close to the national midpoint.
This version is a planning workflow: plug in your assumptions, compare scenarios, and tighten your scope before requesting quotes. The numbers are deterministic, so the same inputs always produce the same range — useful for comparing options side-by-side without provider pressure. Adjust inputs to see what moves the estimate most. This is for planning only, not a provider quote or guarantee.
