Is your solar still working? Most owners can't tell — and the bill is the last to say so.

WattHacker watches every panel on your roof and tells you, in plain words and in dollars, when something is wrong.

WORKING, OR NOT — FIRST THING ON SCREEN
• Your system's status the moment you open the app
• What your panels are making right now, and how today compares
• Your home use, grid flow, and battery too, if your system has them

EVERY PANEL, NOT JUST THE TOTAL
• See each panel individually, updated through the day
• Spot the one that's running short, before it shows up on your bill
• What shade costs you, measured roof face by roof face

YOUR BATTERY, TOO
• Have a Tesla Powerwall? Connect it (read only) and it shows beside your panels
• How full it is right now, and how long it will last
• What it stored and what it used, day by day

WE WATCH IT, SO YOU DON'T HAVE TO
• A panel drops: we tell you, within days, in dollars
• The monitor goes quiet: we notice and tell you
• Alerts come to this phone, by email, or both — your choice, per alert
• No alerts in the middle of the night

YOUR DATA IS YOURS
• We never sell it
• Export your full history as a spreadsheet anytime, on any plan
• Independent: not SunPower, not an installer, not a panel maker

WHAT YOU NEED
WattHacker works with a WattHacker monitor, a small plug-in device that reads your own solar gateway on your home network. It works with SunPower (PVS5 or PVS6) and Enphase systems. Setup takes about 15 minutes. Order a monitor at watthacker.com.
