What’s new
Version 2.6 · Updated October 20, 2026
New in 2.6: • Compare days: in Charts › Day, lay yesterday, the same day last year, your record day or any date over the day you are looking at, with that day's total and the difference in percent. • Compare your systems: with two or more systems, the Week, Month, Year and Total charts put up to four of them side by side, per kWp so different sizes compare fairly. • Monthly report: after each month, the Dashboard offers a one-page PDF per system. Mail, share or save it in one tap; a reminder on the 1st can point you to it. • Output per kWp: the Dashboard, Charts and Detailed Data show your production per kWp, for every day and period. • One day as CSV: export a day's readings from Charts › Day. Improved: • Before iOS asks, HelioPeak explains what it will notify you about. • HelioPeak now reads an answer from PVOutput correctly even when it starts with stray characters. • New Help & FAQ sections, with ⓘ buttons for the new features.
