How to Monitor Your Solar Panels with Smart Home Tech UK 2026

Installing solar panels is just the beginning. Without the right monitoring and automation in place, you could be missing out on a significant chunk of your potential savings. Smart home technology makes it easier than ever to see exactly what your panels are generating, when, and how best to use that free electricity. Here’s how to get started.

Inverter Monitoring Apps: Know What Your Panels Are Producing

Most modern solar inverters come with their own monitoring apps. The key platforms to know in the UK are:

• GivEnergy: Widely used in UK installations, GivEnergy’s app shows real-time generation, battery charge levels and grid import/export. Supports integration via a local API.
• Solis: Popular with budget-conscious installers, the SolisCloud app gives solid historical data and daily production graphs.
• SolarEdge: One of the more polished monitoring platforms, SolarEdge offers panel-level data, which is invaluable for spotting underperforming strings or shading issues.

If you’re still deciding whether to invest in solar at all, it’s worth reading up on whether solar panels are worth it in the UK before committing to a system and a monitoring platform.

Integrating Solar Data into Your Smart Home Hub

For a unified view of your home’s energy, you’ll want to pull solar data into a central hub. Home Assistant is the most powerful option for this — there are community integrations for GivEnergy, SolarEdge, Solis and most other major inverters. Once connected, you can build dashboards showing generation, consumption, battery state and grid import all in one place.

If you’d rather avoid the technical setup, Google Home and Amazon Alexa offer basic energy visibility through compatible devices, though neither matches Home Assistant’s depth. Learn more about setting up a smart home hub that can bring all your devices together.

Automating Appliances to Run During Solar Hours

The real financial win from solar monitoring comes when you automate your heavy appliances to run when generation is high. Practical examples include:

• Dishwasher and washing machine: Use smart plugs (TP-Link Tapo, IKEA, or Shelly) to power these on only when solar output exceeds a threshold — typically 1–2 kW.
• EV charging: Zappi chargers and others support “eco mode” charging that uses surplus solar generation automatically.
• Hot water immersion: A myenergi Eddi device diverts surplus solar to your hot water cylinder, replacing expensive grid electricity with free solar heat.
• Tumble dryer and oven: Less critical, but scheduling these via Home Assistant automations during peak solar hours (usually 11:00–15:00 in summer) adds up.

Smart Plugs and Whole-Home Energy Monitors

A whole-home energy monitor like the Hildebrand Glow (which reads your smart meter in near real-time) or the Efergy Engage clip-on monitor gives you accurate consumption data to complement your solar generation figures. Pair this with smart plugs on individual appliances to see exactly which devices are drawing power and when.

For individual appliance monitoring, the TP-Link Tapo P110 and Shelly Plug S both provide energy metering alongside remote switching — ideal for building automations based on actual wattage rather than guesswork.

Setting Up Alerts for Underperformance

Even well-maintained systems can underperform due to shading, soiling or inverter faults. Set up automated alerts so you’re notified if:

• Daily generation falls more than 20% below the seasonal average
• A string or panel stops reporting data entirely
• The inverter shows a fault code

In Home Assistant, these can be configured as notifications to your phone. SolarEdge and GivEnergy also support email alerts natively within their apps.

Getting Started: A Practical Checklist

If you’re new to smart solar monitoring, work through this in order:

• Download your inverter’s official app and confirm data is flowing correctly
• Add a whole-home energy monitor to track consumption alongside generation
• Fit smart plugs to your two or three biggest daytime appliances
• Set up a simple automation: run washing machine when solar > 1.5 kW
• If comfortable with Home Assistant, build a full energy dashboard and add alerting

Smart monitoring turns passive solar panels into an actively managed energy asset. Even without battery storage, you can meaningfully reduce what you import from the grid simply by shifting when you use power.
