Solar Panel Monitoring: Apps & Systems Explained
Monitoring is how you know your solar’s actually working — and how you squeeze the most from it. Here’s what it shows, the main types, and the apps that run it.
The short answer
Most solar systems come with monitoring built in through the inverter’s own free app — connect the inverter to your WiFi and you can see your generation on your phone in real time. That’s the baseline, and almost every modern install includes it.
Beyond that, monitoring comes in three levels: basic generation-only (inverter app), consumption monitoring (adds what you use and export), and panel-level (each panel individually, via optimisers or microinverters). The real value is twofold: catching faults early — so a quiet problem doesn’t cost you months of lost generation — and maximising savings by timing your usage to your solar. Here’s how it all works.
What this guide covers
Solar monitoring is one of those things people don’t think about until they wish they had it — usually when a bill creeps up and they realise the system’s been underperforming for months unnoticed. Good monitoring turns your solar from a “fit and forget” black box into something you can actually see and optimise. Here’s what’s available and what’s worth having.
What does solar monitoring show you?
At its core, monitoring answers the question “is my solar working, and how well?” Depending on the level, it shows:
- Generation — how much your panels are producing, live and over time (day/month/year).
- Consumption — how much electricity your home is using (needs a consumption meter).
- Export — how much surplus you’re sending to the grid (ties into your SEG payments).
- Battery status — charge level and flow, if you have storage.
- Per-panel output — each panel individually, if you have optimisers or microinverters.
The more of this you can see, the better you can both spot problems and make the most of your generation — the two real jobs of monitoring.
The three levels of monitoring
| Level | What it shows | Cost |
|---|---|---|
| Generation-only (inverter app) | Total system output | Included as standard |
| Consumption monitoring | Generation + usage + export | Small add-on (a CT meter) |
| Panel-level | Each panel individually | More upfront (optimisers/microinverters) |
Generation-only is what nearly every system includes free via the inverter app — fine for checking your solar’s producing. Consumption monitoring adds a current-transformer (CT) meter so you see your usage and export too, which is where the money-saving insights come from. Panel-level needs optimisers (like SolarEdge) or microinverters (like Enphase) on each panel — more detail and more cost, most useful on shaded or complex roofs. For most homes, generation-plus-consumption is the sweet spot.
The main solar monitoring apps
You don’t usually pick a monitoring app separately — it comes with whichever inverter or battery brand you have. The common ones:
| Brand | App |
|---|---|
| SolarEdge | mySolarEdge (strong panel-level view) |
| Enphase | Enlighten (microinverter, per-panel) |
| GivEnergy | GivEnergy app / portal |
| Fox ESS | Fox ESS Cloud |
| Solis | SolisCloud |
| Growatt | ShinePhone |
| SolaX | SolaX Cloud |
They’re all free and broadly similar — real-time generation, historical charts, and (with the right hardware) usage, export and battery data. Since the app follows the equipment, it’s worth glancing at a brand’s monitoring when you choose your inverter: some (like SolarEdge and Enphase) are particularly strong on per-panel detail. If your app ever stops showing data, it’s almost always a WiFi/connection issue, not a panel fault — the panels keep generating regardless.
Why monitoring matters: faults & savings
Two jobs: catch problems, and save more
1. Catching faults early. This is the big one. Without monitoring, a fault — a failing inverter, a dead string, a pest problem shading panels — can quietly cost you generation for months before you notice it on a bill. With monitoring, you see the drop in the app straight away and can get it fixed before it costs much. Monitoring is effectively your early-warning system, and it’s why we always suggest actually checking your app now and then rather than ignoring it.
2. Maximising savings. Monitoring (especially with consumption data) shows when you’re generating surplus — so you can run the washing machine, charge the EV or top up the battery on your own free solar rather than buying from the grid. That shift to self-consumption is where a lot of the real savings live, and you can’t optimise what you can’t see.
Panel-level monitoring: is it worth it?
Panel-level monitoring — seeing each panel individually — needs optimisers or microinverters on every panel. Whether it’s worth the extra cost depends on your roof:
- Worth it if: your roof has shading, multiple orientations, or a complex layout — per-panel data lets you pinpoint exactly which panel is underperforming, and optimisers also improve output on shaded arrays.
- Often not needed if: you have a simple, unshaded, single-orientation roof — a standard string inverter with whole-system monitoring is usually enough, and cheaper.
It’s the same trade-off we cover in our optimisers guide: great on tricky roofs, often unnecessary on simple ones. Don’t pay for per-panel monitoring you won’t benefit from — but if your roof is complicated, it’s genuinely useful.
Monitoring: the honest summary
✓ What monitoring gives you
- See your generation live & over time
- Catch faults early (before they cost you)
- Time usage to your own solar (save more)
- Track export & battery (with the hardware)
- Free inverter app on nearly every system
- Per-panel view on optimiser/micro systems
✗ Things to know
- Basic app shows total only, not per-panel
- Consumption/export needs a CT meter
- Per-panel needs optimisers/microinverters
- App needs WiFi — drops = data gaps, not faults
- Only useful if you actually check it
Frequently asked questions
How do I monitor my solar panels?
Most systems include monitoring via the inverter’s app — connect the inverter to WiFi and view generation on your phone. Add a consumption monitor to see usage/export too, or optimisers/microinverters for per-panel data. Most modern installs give you an app as standard.
Is there an app to monitor solar panels?
Yes — nearly every inverter brand has a free app: mySolarEdge, Enphase Enlighten, GivEnergy, Fox ESS Cloud, SolisCloud, Growatt ShinePhone, SolaX Cloud. The app follows your equipment rather than being chosen separately.
Why does monitoring matter?
Two reasons: it catches faults early (you see a generation drop in the app rather than months later on a bill, so you can fix it cheaply), and it helps you save more by showing when you have surplus to use for appliances, EV or battery charging.
Can you monitor individual panels?
Only with panel-level hardware — optimisers (SolarEdge) or microinverters (Enphase) on each panel. A standard string inverter shows total output only. Panel-level costs more but is useful on shaded or complex roofs.
Do all panels come with monitoring?
Almost all modern installs include inverter-app monitoring as standard, if the inverter’s connected to WiFi. Depth varies — basic shows generation; advanced adds usage, export and per-panel data. Confirm the level with your installer.
Why has my solar app stopped showing data?
Usually a lost connection — the inverter’s dropped off WiFi (router change, password, signal) or the provider’s servers are down. The panels keep generating; it’s just the data link. Reconnect WiFi or check for an outage. If it coincides with a real generation drop, get it checked.
Set it up, then actually check it
The bottom line: Monitoring comes free with nearly every modern system via the inverter app — the trick is using it. It’s your early-warning system for faults (catching a quiet problem before it costs months of generation) and your tool for timing usage to your own solar. Add consumption monitoring for the savings insights; add panel-level only if your roof is shaded or complex.

Solar monitoring is one of the most useful — and most underused — parts of owning solar. Nearly every modern system includes it free through the inverter’s app, so the real question isn’t whether to have it but which level and whether you actually use it. Generation-only is the baseline; adding consumption monitoring is where the money-saving insight comes from; panel-level is worth it mainly on shaded or complex roofs.
However good the monitoring, its value depends on you glancing at it now and then — because that’s how you catch a fault early before it quietly costs you, and how you shift usage onto your own free solar. When you go solar, make sure your installer sets monitoring up properly and shows you the app. A free quote gets you a system specified right — monitoring included.
