Solar Panel Visualizer - A solar panel array performance overview card

NoUsername10 · March 11, 2026, 10:02am

Hello everyone.

Ive made this lovelace card to visualise your solar panel installation.
It supports individual power and energy sensors, color change depending on current output, array checks and a lot more.

Quick Facts

Built for visual clarity: panel tiles, KPI row, status labeling, and popup diagnostics, for small and big screens.
GUI-first setup: start with rows/columns, then configure each panel slot.
Supports large systems: scales to 100+ panels when needed.
Drag-and-drop panel reordering directly on the card.
Quick setup by tapping unconfigured panels.
Array Health Check for peer comparison and underperformance detection.
Inverter status matching with configurable working/fault terms.
In-card history graphs in panel and KPI popups (1h, 6h, 24h).
Auto-populate sensors by prefix (fill empty slots in order) during setup.
No yaml needed, everything is setup in the card settings.

Overview of the card (Gif video):
Tap to play or right click and select “Play animation” if it doesn’t start automatically.

Thanks a lot for the great work on building that card!
It gives a great & easy overview of the panels, awesome.

@NoUsername10 is there a way to customize/remove the dark background ? And to change the default font color?
It’ s not easy to read on my instance as I have black font on the dark grey background as you can see.
Thanks a lot for having build that card, it’s pretty good!
Loving the ability being able to click to see more details as well!

Have a nice day
