What happened to it
The portal wasn't relocated and there's no new address to bookmark. SunPower filed for Chapter 11 bankruptcy in 2024, and on September 20, 2024 all official support was shut down — the customer web portal, the mySunPower app, and the 1-800-SUNPOWER line, together. Roughly 600,000 residential systems were affected.
SunStrong Management subsequently took over the monitoring platform, primarily serving lease and PPA customers, and rebuilt the app as freemium: a free "Basic" tier with real-time power flow and system health, and Premium at about $9.99/mo for history, panel-level data and analytics.
The part that stings: your history
Production history that lived only in SunPower's cloud generally went with the cloud. There's no honest way to soften that. It matters more than people expect, for two reasons:
- Degradation. Panels lose a small amount of output each year, and the only way to know whether yours are ageing normally is to compare like-for-like against previous years.
- Resale and warranty. A documented production record is what supports a warranty claim or reassures a buyer that the system on the roof actually performs.
Whatever you choose next, its history starts the day you connect it. That's the one argument for not leaving this for another six months.
Getting a view back
Your gateway — the PVS5 or PVS6 near your electrical panel — never stopped collecting data. It reports locally on your own network, which is why independent monitoring is possible at all. Three routes, in ascending order of convenience:
- SunStrong's app. The official continuation. Free tier for a basic view; Premium for history and panel detail.
- Do it yourself. Free and open-source: the Home Assistant integrations
krbaker/hass-sunpowerandsmcneece/ha-esunpower, orthomastech/SunPower-Web-Monitor. Real projects, actively used. They need an isolated network segment, some patience, and occasional maintenance when firmware changes. - A plug-in monitor. Hardware that does the local reading and hosting for you.
Don't forget the warranties
While you're sorting monitoring out, this is the moment to check equipment coverage — the company warranty is gone, but the manufacturers' warranties survive and are claimed separately. Enphase covers microinverter parts but no longer labor. Maxeon honors panel warranties but required self-registration by December 31, 2024. Qcells, Fronius, REC and Fimer are equipment-only, excluding labor and shipping. Start by finding your original contract and identifying who made what.
Where Watt Hacker fits
Watt Hacker is a small monitor that plugs into your existing SunPower PVS5 or PVS6 gateway on your own home network and reads it directly. It doesn't rely on SunPower's or SunStrong's servers, because for owners like you those are either gone or behind a paywall. No electrician and no rewiring.
- The monitor is $50 once (list $100), with a 30-day money-back guarantee.
- Kilowatt is free forever — live power and per-panel status, no card on file. $58 to start (monitor + $8 shipping).
- Megawatt adds full history, dollar-framed alerts and reports: $8/mo, or $72/yr ($6/mo). 1 month free with a monitor, free shipping, cancel anytime.
- Built by one person, not a company that can be sold out from under you. Who's behind it.
Common questions
When did the SunPower web portal shut down?
September 20, 2024. SunPower shut down its support operations that day, taking the customer web portal, the mySunPower app and the 1-800-SUNPOWER phone line offline together, following its Chapter 11 bankruptcy filing earlier in 2024.
What replaced the SunPower web portal?
SunStrong Management took over the monitoring platform and rebuilt the app on a freemium basis, with a free Basic tier and a paid Premium tier. Its focus is primarily lease and PPA customers. Owners who bought their systems outright often find independent local monitoring a better fit.
Can I get my old production history back?
In most cases, no. Historical data that lived only in SunPower's cloud went with it. Any new monitoring starts building history from the day you connect it, which is a good reason not to put it off.
