If your solar monitoring app shut down because the provider discontinued its platform, you’re not alone — and your system is still working. Thousands of homeowners have lost monitoring access in recent years due to cellular network retirements, company bankruptcies, and platform discontinuations. The good news: monitoring loss is frustrating but not a system failure, and you have options to restore visibility into your production data.
Why solar monitoring apps shut down
Three main causes kill solar monitoring platforms: cellular network retirements, company bankruptcies or acquisitions, and voluntary platform discontinuations.
The 2G and 3G cellular sunset eliminated monitoring for thousands of systems installed before 2015. Many early solar installations used cellular modems to transmit production data from the roof to the cloud. When carriers retired those networks between 2020 and 2022, the hardware stopped communicating. SunPower, SolarEdge, and Enphase all had systems affected by this transition — though manufacturers with active support programs offered hardware upgrades to 4G or WiFi connectivity.
Company failures create monitoring orphans. The SunPower bankruptcy in 2024 left tens of thousands of homeowners without access to their monitoring portal. When a solar company goes under, their proprietary monitoring platform often goes dark within months. Acquisitions can have the same effect — the acquiring company may migrate customers to a new platform or simply shut down legacy systems to cut costs.
Some manufacturers voluntarily discontinue older monitoring platforms as they release new technology. If your system is more than ten years old and the monitoring suddenly stops working, check whether your inverter manufacturer announced an end-of-life date for that monitoring generation.
Your panels still work without monitoring
This is the most important thing to understand: production monitoring and electricity generation are separate systems. Your panels generate power whenever the sun hits them. Your inverter converts that DC power to AC and feeds it into your home electrical panel. None of that requires an internet connection or a monitoring app.
What you lose is visibility. You cannot see real-time production, track daily or monthly output, or get alerts if production drops. Your utility meter still spins backward during the day when you generate excess power — net metering credits still accumulate on your bill. The electrons keep flowing. You just cannot watch them flow.
For many homeowners, especially those with reliable systems and predictable production patterns, losing monitoring is an annoyance rather than a crisis. If your electric bills show the expected savings and you are not having performance issues, you may decide you can live without detailed production data.
That said, monitoring serves real purposes: catching performance problems early, validating that your system is producing what the installer projected, and satisfying curiosity about how much power you generated today. If those matter to you, read on.
Switch to your inverter manufacturer’s native app
If your monitoring died because your installer’s branded app shut down but your inverter hardware still works, you can often access production data directly through the inverter manufacturer’s monitoring platform.
SolarEdge systems have built-in monitoring through the SolarEdge monitoring portal and app. If your installer gave you a custom-branded monitoring interface, it was likely just a white-labeled wrapper around SolarEdge’s platform. Log in directly at monitoring.solaredge.com using your site ID or installer credentials. If you never set up a SolarEdge account, contact SolarEdge support with your inverter serial number and proof of ownership.
Enphase systems with Envoy gateways report to Enphase Enlighten. Same principle: if you were using an installer’s branded portal, switch to Enlighten directly. You will need your Envoy serial number and system activation credentials. Enphase customer support can help you claim an existing system if you do not have login details.
SMA, Fronius, and other major inverter brands all offer native monitoring platforms. Check your inverter manufacturer’s website and search for their monitoring or customer portal. Most allow you to register an existing system using the inverter serial number.
This option works only if your inverter has built-in monitoring capability and the hardware is still communicating. If the monitoring died because of a 2G/3G modem, you will need to upgrade the communication hardware first — more on that below.
The SunPower monitoring problem
SunPower’s bankruptcy created a uniquely frustrating monitoring situation. The company’s proprietary mySunPower monitoring portal went offline in late 2024, and SunPower panels installed with SunPower-branded microinverters or optimizers often cannot be monitored through standard Enphase or SolarEdge platforms.
If you have a SunPower system installed after 2015, your microinverters are likely rebranded Enphase units. Check whether you have an Enphase Envoy gateway installed — it is a small white or silver box usually mounted near your electrical panel or in the garage. If you do, you can register the system with Enphase Enlighten even if it was originally set up through SunPower’s portal. You will need the Envoy serial number and possibly help from Enphase support to reactivate monitoring under your own account.
Older SunPower systems with proprietary monitoring hardware are harder to salvage. If your system communicates via a discontinued cellular modem and SunPower is no longer offering upgrades, third-party monitoring or system replacement may be your only options.
Some regional SunPower dealers still provide monitoring and service to existing customers even after the parent company’s bankruptcy. If your installer is still in business, contact them first. If not, consider whether monitoring is worth the cost of adding third-party hardware or if you would rather evaluate system replacement if your panels are over ten years old.
If your installer was bought by another company, see what happens to warranties and monitoring after an acquisition.
Add third-party solar monitoring hardware
If your inverter does not have native monitoring or the communication hardware is obsolete, you can install a third-party energy monitor that clamps onto your main electrical panel or solar production meter.
The Emporia Vue is the most popular DIY option. It is a current transformer (CT) clamp system that installs in your breaker panel and reports energy flow to a smartphone app. You can monitor both solar production and home consumption. Installation is straightforward if you are comfortable working inside your panel — or hire an electrician for $150-$300. The hardware costs around $100-$150.
The Sense Energy Monitor works the same way but adds AI-driven device detection that identifies individual appliances based on their electrical signatures. It costs more ($300-$400) but provides deeper insight into where your power goes. Sense integrates with Tesla Powerwall and other battery systems.
eGauge is the professional-grade option. It is more expensive ($500-$800 installed) but provides revenue-grade accuracy and advanced data logging. Commercial systems and solar professionals use eGauge. Overkill for most homeowners, but if you need certified production data for warranty claims or performance guarantees, eGauge delivers.
All three options monitor production at the meter level — they show total system output but not panel-by-panel data. If you need to diagnose shading issues or individual panel failures, you need inverter-level or optimizer-level monitoring, which only native manufacturer platforms provide.
When to consider full system replacement
If your system is over ten years old and you lost monitoring because the hardware is obsolete, it may be time to evaluate whether replacing the entire system makes more financial sense than patching monitoring back together.
Solar technology has improved dramatically in the last decade. Modern panels produce 20-30% more power per square foot than 2013-era panels. New inverters are more efficient and more reliable. If your system is producing less than it used to — common after ten years due to panel degradation and inverter aging — the cost of new monitoring hardware plus eventual inverter replacement may approach the cost of a full system upgrade.
Run the numbers. Get quotes from local installers for a new system using your current roof layout. Compare the production increase and equipment warranty coverage to the cost of keeping your old system running. In many cases, especially if your inverter is near end of life and your panels are underperforming, a new system pays for itself faster than you think. New systems also qualify for any current state and utility incentives, while monitoring upgrades do not.
This is not always the right call — a well-maintained 12-year-old system with healthy production might have another decade of life. But if you are already facing a monitoring hardware replacement and your production has dropped 15-20% from original projections, talk to a qualified installer about whether replacement makes sense.

Living without monitoring: Is it actually a problem?
Here is an honest take: many homeowners do fine without production monitoring. If your electric bills show the savings you expect and you have no signs of equipment failure, detailed daily production charts are nice to have but not essential.
Your utility bill is itself a form of monitoring. If your summer bills are still low and your net metering credits are accruing as expected, your system is producing power. If your bills suddenly spike without explanation, that is your signal to investigate — and at that point you can call a service technician to diagnose the issue without needing real-time monitoring data.
The main risk of going without monitoring is delayed detection of gradual performance loss. A single failed panel or optimizer might reduce production by 5-10%, which could go unnoticed for months if you are not tracking output. But even that is not catastrophic — when you eventually notice the problem, you can still fix it. Solar panels do not fail suddenly and catastrophically. They degrade slowly and predictably.
If you decide to live without monitoring, at least check your inverter display or status lights monthly. Most inverters have a green light that indicates normal operation. If it turns red or starts blinking, that is your cue to investigate. Keep a mental baseline of your electric bills — if winter bills creep higher than previous winters or summer production credits drop without an obvious cause, that is worth following up on.
Frequently Asked Questions
Final Thoughts
Losing access to your solar monitoring app is frustrating, especially when it happens without warning due to a company shutdown or technology retirement you had no control over. But it is important to keep perspective: your system is still doing its job. The panels are still producing power, the inverter is still converting it, and your electric bill is still lower than it would be without solar.
You have options. If your inverter supports native monitoring, switching to the manufacturer’s direct platform is straightforward and free. If you need to add hardware, third-party monitors like Emporia Vue and Sense deliver reliable production tracking at reasonable cost. And if your system is old enough that monitoring loss is just one of several aging issues, it may be the right time to evaluate whether a full system replacement makes financial sense.
Whatever path you choose, do not let monitoring loss create a sense of urgency that pushes you into a bad decision. Take time to assess your system’s actual performance, research your options, and talk to qualified installers who can give you honest recommendations.
