Is your solar still working?
Most owners can’t tell, and the bill is the last to say so. See every panel, and what each one is costing you.
Your system
SunPower PVS5 or PVS6, or Enphase.
Your warranty
It only reads. Never touches panels or inverters.
Built for you
Not SunPower. Not an installer.
Your data
Never sold. Export it anytime, on any plan.
30-day money-back
Not for you? Full refund.
A real person
Email me. You’ll get a human.
How you find out.
You don’t watch it. We do.
Open it: a verdict.
Working, or not. First thing on screen.
A panel drops: we tell you.
Within days, in dollars. Not on the true-up.
The monitor goes quiet: we notice.
Checked every 10 minutes. You hear within the day.
Nobody who sold you the panels writes the report.
We don’t make panels, inverters, or batteries. Nothing to protect.
All of it on the free plan. Enphase Care sells monitoring and early detection from $399 a year.
What silence costs.
None of these announce themselves. All of them show up on the bill.

Trivial installation
Plug-and-play. Your mother-in-law could install.

Questions, answered
Straight answers — especially the ones a burned SunPower owner deserves.
Yes, if you have a SunPower PVS5 or PVS6 or an Enphase IQ Gateway (also sold as an Envoy). Both sit near your electrical panel.
Have a Tesla Powerwall too? Connect it in the app (read only), and it shows beside your panels.
Still not sure? Email a photo to tony@watthacker.com and I’ll tell you.
