LEARN
Reference hub
Every published page on the site, organized three ways: by city (where the diagnostic and cost math live), by utility (where the net-metering and tariff rules live), and by topic (the explainers, buyer guides, and myth-debunks). The research pages are ungated and organized around homeowner questions. Quote help is optional, clearly separated, and disclosed.

METHODOLOGY
How we research
Numbers on the site trace to NREL PVWatts, DSIRE, the Illinois Commerce Commission tariff record, EIA-861, and the Illinois Shines program filings, listed in the source bar at the top of each policy page. The full editorial policy, what gets cited, what gets refused, and how often each page is re-verified, lives on the methodology page.
