HelioPeak — Solar Tracker

HelioPeak gives you a clean, modern way to follow your solar production and consumption with your PVOutput.org data, on iPhone, iPad and Mac.

DASHBOARD & CHARTS
• Dashboard with live power, today's production and peak, self-use, grid export and import, and estimated revenue
• Production, Consumption and Combined views in the charts
• Interactive charts for Day, Week, Month, Year and Total, with arrows to step through each period and a date picker to jump anywhere
• Your own target line, from the monthly estimates you entered on PVOutput, in the Week, Month and Year charts

COMPARE
• Lay yesterday, the same day last year, your record day or any date behind the day you are looking at
• Show the same period of another year behind your Week, Month and Year bars, with the difference in percent
• Put up to four of your systems side by side, per kWp so different sizes compare fairly, also their day curves
• Year-over-Year Comparison of today, this month and the year to date, with percentage changes and a shareable one-page PDF

SIRI & SHORTCUTS
• Ask how much your system produced today, yesterday or this month, without opening the app
• The same questions in the Shortcuts app, for any of your systems

SOLAR MOMENTS
• Shareable cards for records, milestones, quarter and year recaps, installation anniversaries and sunny streaks, with a notification
• Statistics: all your moments at a glance, the records to beat and the next milestone

INSIGHTS & REPORTING
• Annual Report PDF: a multi-page A4 report with totals, monthly breakdown, peak days and yield, in all six app languages
• Monthly Report: after each month, a one-page PDF per system, the month against last year and your estimate
• Export for AI: one file with your history for the AI assistant of your choice
• CSV and JSON export of your daily production and consumption
• System health dots: see at a glance whether each system reports normally
• Specific Yield (kWh/kWp per year) and Yearly Average, the solar industry's benchmarks
• Estimated revenue from your electricity price, CO₂ savings and a tree equivalent

iPAD & MAC
• Native iPad layout with sidebar, Inspector panel, year heatmap and keyboard shortcuts
• Also runs on Macs with Apple silicon (the iPad version)

NOTES & TIMELINE
• Add notes to any day: cleaning, weather, panel issues
• Browse them in the Timeline; they sync across your Apple devices through iCloud

WIDGETS
• Home Screen widgets in three sizes, the large one with today's curve; each widget can show a different system
• Lock Screen widgets with today's production

UNDER THE HOOD
• Smart caching: works offline, with up to 80% fewer API calls
• Built-in demo system: try the app before connecting your own

PRIVACY FIRST
HelioPeak talks directly to the PVOutput API with your own read-only API key. Your key is stored on your device and goes only to PVOutput. No ads, no tracking. Anonymous usage statistics and crash reports help improve the app; you can switch them off in Settings.

HOW IT WORKS
1. Create a read-only API key on pvoutput.org (Settings, API Access)
2. Enter your System ID and API key in HelioPeak
3. Explore your solar production and consumption

HelioPeak never sees your PVOutput password.

MULTIPLE SYSTEMS
The free version supports one PVOutput system. Unlock unlimited systems with a single in-app purchase.
