## What is OwlWatt?

Your solar contract promised a certain amount of energy. Is your system delivering it? OwlWatt checks — independently of your installer — and tells you when it isn't.

WHAT IT DOES
• Tracks production against your guarantee, daily — this month, this year, on pace or behind.
• Push alert the moment output drops. A dead microinverter or a slow decline can hide for months. OwlWatt catches it — with the numbers.
• Per-panel output and weather-adjusted expectations — the full OwlWatt dashboard, on your phone.
• The production figures from your own contract — guarantee amount, measurement window, degradation schedule — surfaced at a glance.
