What you actually paid on your solar tariff, based only on the grid energy you imported.
Low effort up front. A credible answer that compounds with every bill.
Link Enphase, Tesla, or SolarEdge. We pull your 15-minute production and consumption data automatically.
Drop a PDF anywhere. We parse your tariff and rates, then compute factual vs. counterfactual cost.
Your hero number, IRR, payback timeline, and 30-year projection — updated every time a new bill arrives.
Solar adds real value to a home — but only if you can show it. LightLedger produces credible, defensible reports that buyers, sellers, and agents can trust.
