The short answer
SunStrong Management is an asset-management company that services residential solar contracts on behalf of the investors who own them. It did not sell you your system, did not install it, and is not the manufacturer. It ended up with your account because the contract was sold after a bankruptcy — possibly twice.
How your system changed hands
- 2024 — SunPower filed Chapter 11 and shut down all official support on September 20, 2024, taking the mySunPower app, the web portal and the 1-800 line with it. SunStrong acquired the lease and lease-servicing assets.
- June 2025 — Sunnova filed Chapter 11.
- September 2025 — a group of Sunnova bondholders formed Solaris Assets LLC, bought substantially all of Sunnova's assets, and handed day-to-day operations to SunStrong Management.
- Today — SunStrong says it manages 500,000+ customers and roughly 4 GW, making it one of the largest residential solar asset managers in the country.
None of that was something you agreed to. Contracts are assets, and assets are sold in a bankruptcy. It is also why the company emailing you about your roof is one you have never knowingly done business with — and why the old mySunPower app on your phone quietly became SunStrong Connect without ever disappearing: the App Store listing was renamed in place.
What Connecticut's Attorney General is looking at
This is worth stating carefully, because it is easy to overstate and we are not a neutral party. On 17 March 2026, the Connecticut Attorney General announced an investigation into SunStrong Management LLC. His office and the state's Department of Consumer Protection had jointly received approximately 65 consumer complaints. The AG issued a civil investigative demand seeking records on how systems were transferred from the bankrupt SunPower and Sunnova, contract terms, quality-control mechanisms and complaint records.
According to that announcement, consumers complained that the company was failing to uphold warranties, not responding to consumer complaints, and charging a $10 monthly fee to receive data regarding their solar system's production.
Read that as what it is. A civil investigative demand is a request for documents. It is not a lawsuit, not a judgment and not a finding of wrongdoing — SunStrong has not been found liable for anything, and it is entitled to answer. Plenty of investigations close with no action. We are pointing you at the Attorney General's own announcement so you can read the primary source rather than take our word for it.
We flag it for one reason: if you have been wondering whether it is unreasonable to be annoyed at paying a monthly fee to see your own production data, a state regulator has at least thought the question worth asking.
If you lease your panels
Stop before you buy anything. Lease and PPA customers get SunStrong's paid monitoring tier included, and SunStrong is still your service contact for the system itself. If the app is not working for you, that is a support problem to raise with them through their Help Center — not a reason to pay a third party. You do not need our monitor, and we would rather say so here than take the order.
If you own your system outright
Then the thing worth knowing is that SunStrong is not the source of your data — your gateway is. The PVS6 in your garage measures your production and holds it locally on your own network. Any app, theirs or anyone else's, is just a window onto it.
SunStrong's free tier shows real-time power flow and system health. History, panel-level monitoring and analytics sit behind Premium at $9.99/mo ($99.99/yr, checked August 2026 — confirm current pricing with SunStrong). Your honest options:
Keep paying SunStrong
Reasonable if the app does what you need, and nothing to install. It also keeps everything with the company that already services your contract.
Pay Enphase to replace the gateway
A technician swaps the SunPower gateway for an Enphase one and you move onto their platform, with no monthly monitoring fee afterwards. Hardware plus a service call, so a real up-front cost, and you need to be home. $999 as of August 2026 — confirm current pricing with Enphase. Not available for SunVault battery systems, which Enphase's monitoring-restoration service explicitly excludes.
Read the gateway you already own
A plug-in monitor reads your existing PVS6 on your own network — no technician, no appointment, and no account that anyone can switch off or sell. With the WattHacker monitor, seeing your panel data is free forever: every panel, live, no subscription and no card on file. $99 once, then nothing; an optional plan at $6/mo (billed annually) adds history and alerts.
If you are technical, you can also read the gateway yourself for free with open-source software, at the cost of setting it up and maintaining it.
Trying to log in?
SunStrong has two separate logins and most sign-in problems are someone using the right password on the wrong one — billing lives in a different system from monitoring. We wrote that up separately: which SunStrong login you actually need.
Where WattHacker fits
The WattHacker monitor is a small box that plugs into your existing SunPower 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 technician, no electrician, no rewiring — you plug it in yourself.
- The monitor is $99 once, with a 30-day money-back guarantee.
- Free to see your panel data, forever — every panel, live, no subscription and no card on file.
- An optional premium plan at $6/mo (billed annually) adds the memory: full history kept for good, year-over-year comparison, and alerts told to you in dollars.
- Built by an electrification superfan who wants to help others use their solar smarter, lower their utility bills, and clean up the planet. Who's behind it.
Real panels, real production, no signup.
Common questions
Who is SunStrong Management?
An operations and asset-management company that services residential solar contracts — leases, loans and power purchase agreements — on behalf of the investors who own them. It is not the company that sold or installed your system. It took over SunPower's lease and servicing assets after SunPower's 2024 bankruptcy, and in September 2025 took on the legacy Sunnova portfolio too.
How did they end up with my system?
Through two bankruptcies. SunPower filed Chapter 11 in 2024 and shut down support on September 20, 2024. Sunnova filed Chapter 11 in June 2025; a group of its bondholders formed Solaris Assets LLC, bought substantially all of Sunnova's assets, and handed operations to SunStrong. You were not asked, because contracts are assets and assets get sold.
How big are they now?
Following the Sunnova integration, SunStrong says it manages more than 500,000 solar customers and around 4 GW of distributed generation and storage — which makes it one of the largest residential solar asset managers in the United States.
Is SunStrong under investigation?
Yes, in at least one state. On 17 March 2026 the Connecticut Attorney General announced an investigation into SunStrong Management LLC, after his office and the Department of Consumer Protection jointly received approximately 65 consumer complaints. An investigation is a request for records, not a finding of wrongdoing — SunStrong has not been found liable for anything, and it is entitled to respond.
Do I have to use SunStrong's app to see my solar data?
No. Your PVS6 gateway holds your production data locally, on your own home network. It can be read without any subscription and without an account with anyone. SunStrong's app is one way to see it; it is not the only way, and it is not the source.
I lease my panels. Does any of this change what I should do?
Not really, and you should be careful before buying anything. Lease and PPA customers get SunStrong's paid monitoring tier included, and SunStrong remains your service contact for the system itself. Talk to them through their Help Center before paying anyone else for monitoring.
