Energy monitors show how much electricity your home uses, and some also show what your solar panels send back to the grid. Most of the models here clamp onto a circuit panel rather than plugging into one outlet, so they can read the whole house or selected circuits.

Before you pick one, check how many circuits it reads, whether it measures solar export or net metering, and whether it relies on Wi-Fi, Ethernet or a cloud account. For the units and terms used in these listings, see solar terms explained.

Every specification on this page comes from each product’s Amazon listing, checked on 7 November 2026. We have not used these products ourselves, so the picks are based on published specifications only.

For the units behind the readings, see watts, watt-hours and volts explained and how to find out how much energy your devices use.

Quick picks

How we chose these

  • Solar and export readings Look for bi-directional or net metering support if you have panels or a battery.
  • Circuit count and clamp size The number of sensors sets how much of the panel you can see, and clamp rating shows the largest load each one reads.
  • Connection and data access Wi-Fi, Ethernet, Z-Wave, cloud storage and local access all change how you view and keep your data.
  • Install and safety notes Panel type, phase support and any electrician advice matter more than app features.

Practical tips

  • Check how many circuits the listing covers, since the number of sensors sets how much of the panel you can see.
  • Confirm your panel setup. Some listings need extra sensors for three-phase or busbar-only panels.
  • Note the connection type and app region before buying, since some listings require 2.4 GHz Wi-Fi or limit the app to certain countries.

FAQ

Do these monitors work with solar panels?

Several listings say they measure solar output, net metering or bi-directional power flow. Check that the model you pick names the function you need.

Do I need an electrician to install one?

Nestool recommends a qualified electrician for panel wiring if you are not familiar with it. Review the installation notes in the listing before you start.

Is a plug-in watt meter the same as a home energy monitor?

No. This list covers panel-based and circuit-level monitors, while plug-in meters read one appliance at a time.
