Installer apps show that your panels produce energy. They don't show whether production meets the guarantee in your contract. Those are two different things — and only one of them protects your investment. OwlWatt reads your contract, watches your roof, and works for you.
Illustration. The remaining panels keep producing, the charts stay green, and the gap accumulates quietly — until the measurement window in your contract closes.
Picture it: two years after installation, your electricity bill is lower than before — but not as low as the proposal said it would be. You open the installer's app. Green bars. Upward arrows. Everything looks normal.
"Normal" according to the app means the panels are producing. Your contract promised something more specific: a number of kilowatt-hours, measured over a defined window, with a remedy if the system falls short. The app doesn't know that number. It was never asked to check.
And the guarantee only works while its measurement window is open. Miss the window because nobody was comparing, and the opportunity quietly expires.
Green bars aren't a guarantee. Your contract is — if someone's watching it.
OwlWatt pulls panel-level production data straight from your existing microinverters — automatically, every 15 minutes.
We extract the terms that matter — kWh targets, measurement windows, degradation schedules, exclusions — and set your personal baseline.
Actual production, compared continuously against what was guaranteed. If a shortfall develops, you get an alert and the documentation to act on it. If everything's fine, you get to stop wondering.
OwlWatt provides information and documentation, not legal advice. If a shortfall develops, your report gives you the production record and the verbatim contract terms to review with a licensed attorney.
Suppose a 10 kW system runs 8% below its production guarantee — say a failed microinverter that nobody catches, masked by the panels that still work. Here is what that scenario looks like over a 25-year system life, next to the cost of watching for it.
$87.89/yr × 25 years, price held constant for illustration. One detailed production report every year, alerts the moment a gap opens.
8% under-production on a 10 kW system, valued at retail rates of $0.18–$0.35/kWh over 25 years — energy you paid for and bought from the utility instead.
Assumptions, in the open: hypothetical scenario, not a measured average · production ≈ 13,000 kWh/yr for a 10 kW system at 1,300 kWh/kW-yr · retail rate range reflects current residential prices across U.S. markets · whether any shortfall is recoverable depends on your contract's remedy terms — that's a question for a licensed attorney, with OwlWatt's documentation in hand.
