Solar production tracking for PVOutput
HelioPeak is a native iOS app for tracking solar production through PVOutput.org. It reads data directly from PVOutput with your System ID and a read-only API key, then presents the results as charts, statistics, widgets, and exports.
The app is designed for individual PVOutput users who want a local, Apple-platform companion for monitoring production, checking system health, comparing time periods, and keeping optional notes. It runs on iPhone, iPad, and Apple Silicon Macs, and the site states that one App Store purchase covers those three platforms.
Features
Multiple chart periods
Includes day, week, month, year, and all-time charts for both production and consumption, with calendar and rolling views.
Home screen widget
Provides a home screen widget in three sizes with today's production and consumption, plus an intraday chart on the largest size.
Data export
Exports full history as CSV, JSON, or a multi-page annual PDF report, with notes included in CSV and JSON exports.
Notes and iCloud sync
Lets you add private notes to specific days for maintenance, observations, milestones, or issues, and syncs them across your Apple devices via iCloud.
Multiple systems
Supports multiple PVOutput systems in one app, with a systems list, per-system statistics, and a quick switcher for Dashboard and Charts.
Common use cases
Monitor daily output
Check current production, peak power, and estimated revenue from the live dashboard when you want a quick status readout after a refresh.
Review production trends
Compare day, week, month, year, and all-time performance to understand seasonal changes or spot differences between calendar and rolling views.
Log system events
Keep maintenance notes, observations, or milestone records attached to specific dates, with the same notes available on your Apple devices through iCloud.
Manage several solar systems
Switch between multiple PVOutput installations in one app and review each system's lifetime statistics from the Systems tab.
Share or analyze data elsewhere
Export data to CSV, JSON, or PDF when you need a spreadsheet, a script-friendly data file, or a shareable annual report.
Pros and Cons
Pros
- Connects directly to PVOutput.org without an intermediary server.
- Supports iPhone, iPad, and native Apple Silicon Mac use from one app purchase.
- Offers several export formats, including CSV, JSON, and PDF.
- Includes private notes with iCloud sync across the user's Apple devices.
- Provides system health indicators and historical comparisons for ongoing monitoring.

FAQ
What do I need to get started?
You need a PVOutput.org account with at least one registered solar system. In HelioPeak, enter your System ID and a read-only API key from PVOutput's API settings.
Is HelioPeak free?
Yes. HelioPeak is free for one solar system and includes charts, live dashboard, exports, notes, and CO₂ tracking. Multiple systems require a one-time in-app purchase, and there is no subscription.
Can I try the app without a PVOutput account?
Yes. During onboarding, you can choose a demo system and explore the app before connecting your own PVOutput account.
How does HelioPeak connect to PVOutput?
HelioPeak connects directly to PVOutput.org from your device. There is no intermediary server, and your PVOutput credentials are not sent to HelioPeak's servers.
Where can I find full pricing details?
The pricing page at /pricing returns a page-not-found result on the site, so the available source material does not provide a separate published pricing page beyond the in-app purchase information in the FAQ and privacy policy.
