Almost every solar company advertises "24/7 monitoring," which is technically true and often doesn't mean what customers expect. Here's what residential solar monitoring actually does, what alerts you should expect, and what separates marketing language from a useful service.
What monitoring actually measures
A modern residential solar monitoring system tracks data at several levels:
- System-level production — total kilowatt-hours your array is producing, typically updated every 5–15 minutes.
- Panel-level or string-level production — whether specific panels are under-producing relative to their peers. Microinverter systems (like Enphase) do this per-panel; string inverter systems do it per-string.
- Consumption — if a consumption meter is installed, the monitoring also shows how much electricity your home is using in real time.
- Grid import/export — how much you're drawing from or feeding back to the utility.
- Battery state (if you have storage) — current charge level, charge/discharge rate, and operating mode.
What alerts you get (and when)
This is where "24/7 monitoring" claims vary widely between providers. At minimum, a good monitoring system should alert on:
Communication outages
If the inverter or gateway loses connection to the cloud for more than a few hours, the monitoring team gets a flag. Without this alert, you won't know your data has stopped reporting until you manually check the app.
Production anomalies
If your system produces materially less than the weather-adjusted forecast for a few days in a row, that's a signal something is wrong — a tripped breaker, a shaded panel, a failed micro, a dirty array. A good monitoring team catches that before you notice it on your utility bill.
Panel- or string-level faults
A single underperforming panel in a 20-panel array is invisible in total production numbers — the system still looks fine in aggregate. But it represents lost savings. Panel-level monitoring (with microinverters) surfaces this immediately.
Battery issues
If you have storage, the monitoring should alert on things like repeated failed charge cycles, unexpected discharge during on-grid hours, or cell-balancing warnings.
The homeowner's view vs. the service team's view
Most monitoring apps give you — the homeowner — a simple dashboard. Production today, consumption today, savings estimate. That's designed for peace of mind, not for diagnostics.
The service team has a different view. They're watching fleet-wide data, anomaly flags, and alert queues across thousands of systems. When your system flags something, it's their responsibility to respond — not yours.
That said, you should be able to:
- Check your daily production from a phone app.
- See production history month-over-month and year-over-year.
- Get a notification if something is wrong, not just a silent line on a graph.
What "24/7" really means — and what it doesn't
"24/7 monitoring" means the system is sending data 24/7 and the monitoring platform is ingesting it 24/7. It does not mean a human at the service company is staring at your dashboard at 3 AM. Almost no one does that, and no residential homeowner needs it.
What matters is the response SLA: once an alert fires, how quickly does someone notice, triage, and reach out to you? This is the real differentiator between a solid monitoring service and a token one. The honest version of the claim is "automated monitoring with a business-hours response," and that's usually fine for residential. Ask any provider what their actual response target looks like — if they won't give you a number, that's a signal.
What the homeowner should still watch
Even with good monitoring, there are a few things worth checking yourself from time to time:
- Monthly production totals vs. your system's expected output for the season. A significant drop is worth flagging.
- Post-storm or post-heatwave performance. Extreme weather sometimes trips breakers or damages panels — check the system looks normal a few days after.
- Visible dust or debris on the array. California wildfire smoke and seasonal dust can reduce production materially; occasional cleaning helps.
- Inverter indicator lights. If you see a red or amber fault light on your inverter or gateway, that's a signal to check in with the service team.
The bottom line
24/7 monitoring is table stakes in modern residential solar. The real question is whether your provider acts on the alerts quickly and clearly, and whether you as the homeowner get enough visibility to trust the system is doing its job. Under our PPA plans, monitoring is included with the service term. Under loan or direct-purchase options, monitoring comes through the equipment manufacturer's app (Tesla for Powerwall, Enphase for IQ systems), with our team available for support.
