Solaris: Solar & Battery

Your solar panels paid for themselves today. Solaris tells you exactly how much. Now with home-screen widgets and payback tracking. 7-day free trial inside.

One screen. One number. One story.

Solaris turns your FoxESS inverter and Octopus Energy bill into the satisfying daily check-in your solar panels deserve. See exactly what your system did today — and exactly what it cost — using your real half-hourly tariff rates, not estimates.

— THE DAILY HERO — A single beautiful number tells you whether today was a Sunshine Win, a Tiny Win, or a Cosy Day. Every day feels rewarding. No spreadsheets. No squinting at clinical dashboards.

— REAL MONEY, NOT GUESSES — Solaris reads your actual Octopus tariff (Agile, Intelligent Go, Flux, Cosy — whatever you're on) and pairs it with your FoxESS half-hourly generation, import and export data. The result is the most accurate "what did my solar do today?" number you'll find on iPhone.

— HOME SCREEN WIDGETS — Battery state, today's generation, live power flow, and your payback journey — all on your home screen. Glance and go.

— PRIVACY-FIRST, NO BACKEND — Your data never leaves your iPhone. No accounts. No servers. No tracking. We don't see your usage, ever.

— BUILT FOR UK SOLAR HOMES — Designed for UK homeowners with FoxESS hardware and an Octopus Energy account. Honours Daylight Saving Time, standing charges, export tariffs (SEG and Outgoing Octopus Agile), and tariff changes mid-period.

— SOLARIS PRO — Free tier: today's snapshot, 7-day history, basic widgets. Pro tier: full history, payback tracker, all widgets, push notifications, CSV export. £2.99/month or £29.99/year (50% off intro). 7-day free trial.
