Solar Panel Monitoring Systems: Track Your Output

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.
