Arev Analytics
A solar & battery ROI engine that stays independent by construction — licensees brand their edition, but the mathematics, methodology, and conservative defaults are Arev’s alone and are never tuned to favor a sale. It is licensed white-label to solar professionals. The live calculator is private to our licensees — this page is the open tour: real screenshots, features you won’t find together anywhere else, the printed report, and the mathematics underneath.
Every screenshot below is the real application computing a simulated sample household — an 11.2 kW system with a Tesla Powerwall 3 in California, under NEM 3.0 net billing. Names and numbers are illustrative; the software, charts, and math are exactly what licensees ship.
Solar versus simply investing the money — compounded, fee-adjusted, and taxed at the household's real capital-gains rates. Few tools dare the comparison; Sunalysis leads with it.
One touch re-runs the entire model on a defined conservative set — low escalation, no resale premium, the market alternative at full strength. The analysis argues against itself first.
A living two-week energy simulation with steppers for panels, batteries, and reserve floor — plus storm-conservation modes. Homeowners feel the system before they buy it.
Green Button interval files and Enphase production exports distill into the analysis — the household's actual usage pattern, not a guess.
Import and export priced separately, hour by hour, with battery dispatch that understands the difference — the math that decides whether storage pays in California.
Two-click verified plans for major utilities, or any U.S. tariff by ZIP code from the national utility rate database — seasons, weekends, and up to four windows a day.
EVs against their gas cars, heat pumps against the gas bill, nine appliance conversions — each with honest added load, re-dispatched through solar and battery.
A built-in AI advisor that answers questions from the household's own numbers on screen — and can re-run what-ifs through the engine to answer with math, not vibes.
No quote yet? The engine tests dozens of size-and-battery combinations on the full model and ranks them by long-run net, fastest payback, self-supply, or IRR.
One tap prints a complete, client-ready PDF — typically 25–35 pages — under the licensee's brand: cover with the headline verdict, the 30-year money year by year, what owning protects against, solar versus the market, the evidence section with every chart, and a full audit of assumptions with the "how solid are these numbers" walkthrough. Every figure in it is the analysis the client just watched compute.
The full manual for the application is public — read the Sunalysis User Guide ↗ — step-by-step help for every section, written for homeowners, not engineers.
Sunalysis is a representative-coincidence model: production, load, tariff windows, and battery state are resolved on a common weighted hourly structure, because modern tariffs pay by the hour and exports earn less than imports cost. Storage is a constrained state system — asymmetric efficiency, a reserve floor, throughput-limited cycling, capacity that fades toward a floor:
Every annual figure is the difference between two fully specified households — with the project and without it — so nothing is counted twice. Headline metrics are computed on the asset basis, and the internal rate of return is the root of the present-value polynomial:
Time-value is never hidden in a discount rate — it is shown as its own competing asset, capital-constant across financing structures, net of fees and capital-gains tax. And every release is regression-locked against a corpus of 300 full scenarios executed through two compute paths — 600 computations matched exactly, at zero tolerance — with analytical spot cases, bill reconciliation, and adversarial review layered above it. The complete technical methodology is available to serious licensees under NDA.
Licensees get their own edition — logo, colors, market defaults, and service area — live on their own web address in days. Their clients get an analysis built to argue against itself before anyone else can — with the licensee's name on the cover of every report.
