Is solar panel monitoring free?

Yes. Every major inverter brand includes free monitoring via their app (GivEnergy, SolarEdge, Enphase, Solis, Huawei). No subscription is required. The monitoring connects via your home WiFi.

Can I monitor solar panels on my phone?

Yes. All modern inverter brands offer free iOS and Android apps that show real-time generation, daily/monthly/annual totals, battery status, and consumption data.

What if my monitoring stops working?

Monitoring issues are usually WiFi-related — check your router connection and restart the inverter's WiFi module. If monitoring is down, your panels still generate normally — monitoring is a separate reporting function, not part of the generation process.

Can monitoring show each panel individually?

Only with panel-level monitoring: SolarEdge optimisers or Enphase micro-inverters show individual panel output. Standard string inverters show total system output only. Panel-level monitoring helps identify underperforming individual panels.

How do I monitor my solar panel output?

Every modern solar inverter includes free monitoring via a smartphone app or web dashboard. You can track real-time power output, daily/monthly/annual generation, self-consumption vs export, and system health alerts. The monitoring is included in your inverter — no additional cost or subscription required. Setting up takes 5 minutes during installation.

What Solar Monitoring Shows You

A typical solar monitoring platform displays:

Real-time power output (watts) — see exactly how much your panels are generating right now
Daily generation (kWh) — total electricity produced today
Monthly and annual generation — track performance over time
Self-consumption — how much solar you used directly vs exported to the grid
Grid import — how much electricity you bought from the grid
Battery status (if installed) — charge level, charging/discharging rate
Export data — how much you sent to the grid (for SEG payments)
Historical comparison — compare today's output to the same day last year
Environmental impact — CO2 saved, equivalent trees planted
Alerts — notifications if output drops below expected levels or faults detected

Best Solar Monitoring Platforms in the UK

Your monitoring platform depends on your inverter brand:

GivEnergy (givenergy.cloud): - Excellent UK-developed platform - Shows: generation, battery, consumption, export, import - App: iOS + Android + web dashboard - Special feature: remote battery control, tariff optimisation - Cost: Free with GivEnergy inverter/battery

SolarEdge (monitoring.solaredge.com): - Industry-leading platform with panel-level monitoring (with optimisers) - Shows: per-panel output, system overview, energy flow - App: iOS + Android + web - Special feature: individual panel performance tracking - Cost: Free basic; full panel-level requires SolarEdge optimisers

Enphase Enlighten: - Per-panel monitoring as standard (every micro-inverter reports independently) - Shows: per-panel output, system health, consumption - App: iOS + Android + web - Special feature: automatic fault detection per panel - Cost: Free with Enphase micro-inverters

Solis Cloud: - Budget-friendly but capable platform - Shows: generation, consumption, grid interaction - App: iOS + Android + web - Cost: Free with Solis inverter

Huawei FusionSolar: - Clean, modern interface - Shows: generation, consumption, battery (if applicable) - App: iOS + Android - Cost: Free with Huawei inverter

How to Set Up Monitoring

Your installer should set up monitoring during installation — ask them to do so
The inverter connects to your home WiFi (you need your WiFi password ready)
Download the manufacturer's app on your phone (free)
Create an account and link it to your inverter's serial number
Data typically appears within 15–30 minutes of connecting
If your installer did not set it up, consult the inverter manual — it usually involves pressing a WiFi button on the inverter and connecting via your phone

Using Monitoring to Spot Problems

Monitoring is your early warning system. Here is what to look for:

Normal patterns: - Output peaks around midday (±1 hour depending on season) - Clear days produce a smooth bell curve; cloudy days show spiky, variable output - Summer output is 4–6x winter output - Year-on-year output should be within ±5% (weather variation)

Warning signs: - Zero output on a sunny day: Inverter fault. Check for error codes/red light. Try restarting. - Output dropped 20%+ vs last year: Panel soiling, new shading (tree growth), or degradation issue. - One panel producing much less (micro-inverter/optimiser systems): Panel defect, shading, or wiring issue. - Inverter repeatedly restarting: Grid voltage issue or inverter fault. Contact installer. - Battery not holding charge: Battery degradation or BMS fault. Check warranty.

Catch problems early through monitoring and you avoid months of lost generation.

Third-Party Monitoring Options

If you want more detailed monitoring beyond your inverter's app:

Home Assistant: Open-source smart home platform that integrates with most inverter brands. Allows custom dashboards, automation, and integration with smart tariffs.

Solar Analytics: Third-party monitoring service that adds a separate sensor at your switchboard. Provides independent generation and consumption data. Cost: £200 hardware + £5/month subscription.

CT clamp monitors (e.g., Shelly EM, Emporia Vue): Clip-on current sensors that monitor your main electrical feed. Show total generation and consumption independently of your inverter. Cost: £50–£150.

For most homeowners, the free inverter monitoring app is sufficient. Third-party options are for enthusiasts who want deeper data integration.
