Most homeowners glance at their solar app once after installation and never open it again. That's a mistake — monitoring data is how you catch underperforming panels, inverter faults, and grid-connection issues before they cost you months of lost production. It's also how you build the documented performance record that supports warranty claims. A panel that degrades faster than its warranty allows is only actionable if you have the production data to prove it.
Here's what the major monitoring platforms actually show and how they compare.

Key Takeaways
- Enphase Enlighten and SolarEdge provide panel-level monitoring when paired with their respective hardware — essential for diagnosing shade and underperformance issues
- A single underperforming panel in a string inverter system can reduce whole-string output — monitoring catches this
- Sense Energy Monitor ($299) and Emporia Vue ($79) work with any system including string inverters that lack panel-level data
- Most modern inverters include free cloud monitoring — activate it before your installer leaves on install day
- Production records are critical for warranty claims — gaps in monitoring data can weaken a manufacturer warranty dispute
Why Monitoring Matters More Than Most Installers Say
Your solar system's production should follow a predictable pattern: higher in summer, lower in winter, peaking midday. Deviations from that pattern — a panel that suddenly drops 20% output, an inverter that reports faults overnight, a system that produces 15% less than the previous year — are early signals of problems.
Without monitoring, those problems accumulate silently. You notice something is wrong when your electricity bill is higher than expected, by which point you may have lost 3–6 months of production. With monitoring, you see anomalies within days and can file a service request with your installer or manufacturer.
This matters more for long-term warranty management. If your system is still under a 25-year production warranty in year 12 and you need to claim that a panel has degraded below the warranted minimum, your monitoring data is the evidence. An installer or manufacturer disputing a warranty claim will want to see production records — not just your assertion that the panel isn't working.
Enphase Enlighten
Compatible with: Enphase IQ microinverter systems (IQ6, IQ7, IQ8 series)
Enphase Enlighten is included free with all Enphase microinverter systems. Because each Enphase microinverter operates independently at the panel level, the Enlighten platform can report production data for each individual panel on your roof. You can see exactly which panel is producing 320W in full sun and which one is producing 280W — a difference that might indicate a partially shaded cell, a dirty panel, or a developing fault.
Key features:
- Panel-level production monitoring (real-time and historical)
- System-level production and consumption (with CT sensor add-on)
- Lifetime energy production tracking
- Fault alerts via push notification
- Battery storage integration (for Enphase IQ Battery systems)
- Export/import tracking with IQ Combiner
The Enlighten app is consistently well-rated for ease of use. The data granularity (per-panel, per-15-minutes) is more than most homeowners will ever use but is exactly what you need for warranty disputes or diagnosing a shading problem.
Limitation: Only works with Enphase hardware. If you have a SolarEdge or string inverter system, you need a different platform.
SolarEdge Monitoring
Compatible with: SolarEdge inverter systems with power optimizers
SolarEdge's monitoring platform provides panel-level data via the DC optimizers installed at each panel. Like Enphase, you can see per-panel production — but the monitoring is at the optimizer level rather than the inverter level, which in practice gives you equivalent granularity for diagnosing issues.
Key features:
- Panel-level production data
- System-level energy flow (production, consumption, grid import/export)
- Home energy dashboard (with SolarEdge Energy Hub and EV charger integration)
- Battery state of charge (with SolarEdge Energy Bank)
- Fault alerts and service request submission in-app
SolarEdge's platform is particularly strong for whole-home energy management when you're running the full SolarEdge ecosystem (inverter + optimizer + battery + EV charger). The integration is tighter than Enphase's equivalent setup and better at managing time-of-use rate optimization.
Limitation: Only works with SolarEdge hardware. The monitoring app is functional but rates slightly below Enphase Enlighten for user experience in most independent reviews.
Sense Energy Monitor
Compatible with: Any solar system, any inverter type
Sense is a whole-home energy monitor that installs in your electrical panel (requires a licensed electrician). It uses machine learning to disaggregate your home's electrical load — learning the energy signature of your appliances — and tracks solar production if you add the optional solar CT sensors.
Price: $299 hardware + optional $9.99/month premium subscription
Sense is the go-to solution for homeowners with string inverter systems that don't provide panel-level monitoring. It won't show you which panel is underperforming, but it will show you:
- Whole-system solar production vs. grid consumption in real time
- Which appliances are using the most energy (learned over 2–4 weeks)
- Net energy position (how much you're exporting vs. importing)
- Historical trends by day, month, year
For homeowners who want broader home energy visibility — not just solar — Sense provides context that solar-specific platforms don't. You can see that your HVAC is running 40% more than last summer, which explains the higher grid import despite solar producing normally.
Emporia Vue
Compatible with: Any solar system, any inverter type
Emporia Vue is the budget option — $79 for the Gen 2 smart home monitor with solar monitoring capability. It installs in your main electrical panel with current transformer (CT) clamps and provides real-time and historical energy data.
The Emporia Vue doesn't have the appliance-identification machine learning that Sense does. What it provides is clean, accurate whole-home and solar production data at a fraction of the Sense price.
For homeowners who want basic production verification — confirming the system is producing what it should and spotting obvious anomalies — the Emporia Vue at $79 is a reasonable choice. For homeowners who want the full diagnostic picture, Sense is worth the extra cost.
Platform Comparison
| Platform | Price | Panel-Level Data | Works With | Best For |
|---|---|---|---|---|
| Enphase Enlighten | Free (with Enphase) | Yes — per microinverter | Enphase systems only | Enphase owners; warranty documentation |
| SolarEdge Monitoring | Free (with SolarEdge) | Yes — per optimizer | SolarEdge systems only | SolarEdge owners; whole-home energy management |
| Sense Energy Monitor | $299 + optional subscription | No — whole-system only | Any system | String inverter owners; home energy visibility |
| Emporia Vue | $79 | No — whole-system only | Any system | Budget solar production tracking |
What to Do on Install Day
When your installer wraps up, before they leave, make sure:
- The monitoring portal is activated. Most installers set this up as part of commissioning; verify it's live and you have login credentials.
- You can see live production data. Confirm the app is reading real-time output.
- You've set up production alerts. Most platforms let you set a notification if daily production drops below a threshold.
- You have a reference baseline. Your installer should provide an estimated monthly production schedule based on NREL PVWatts data for your location — save this and compare your actual monthly production against it.
Bottom Line
If you're getting an Enphase or SolarEdge system, activate and use their free monitoring platforms. Panel-level visibility is genuinely valuable for diagnosing underperformance and maintaining your warranty record. If you're on a string inverter system without panel-level monitoring, consider adding a Sense ($299) for robust visibility or an Emporia Vue ($79) for basic production tracking.
The Solar ROI Calculator uses NREL PVWatts estimates — comparing your actual production against those estimates in your monitoring app is a useful annual check to confirm your system is performing as expected.
