Solar Panel Monitoring Apps Compared

Features depend on the equipment installed and the configuration of the system.

What Is a Solar Panel Monitoring App?

A solar monitoring app connects to the equipment responsible for monitoring your PV system, normally through the inverter, battery, communications equipment or an additional energy meter.

Instead of looking at the inverter itself, you can use your phone, tablet or computer to see information about your system.

Depending on the installation, this can include:

• Current solar generation
• Daily generation
• Monthly generation
• Annual generation
• Lifetime generation
• Household electricity consumption
• Grid imports
• Grid exports
• Battery charging
• Battery discharging
• System status
• Fault notifications
• Historical performance

Monitoring applications effectively turn your solar installation into a source of usable energy data rather than simply a collection of panels on the roof.

Why Is Solar Monitoring Important?

Solar panels generate different amounts of electricity throughout the day and year.

Generation is affected by factors including:

• Sunlight levels
• Cloud cover
• Season
• Panel orientation
• Roof pitch
• Shading
• Temperature
• System design
• Inverter performance

A monitoring app allows you to see these changes rather than relying on estimates.

It can also help identify unusual behaviour. If generation suddenly drops compared with normal conditions, the data can provide an early indication that the system requires investigation.

What Can a Solar Monitoring App Show You?

1. Real-Time Solar Generation

The most basic function is showing how much electricity the solar panels are producing at a particular moment.

For example, an app might show that your system is currently generating 3.2kW.

Remember that kW and kWh are different measurements.

• kW = the rate at which electricity is being generated or used.
• kWh = the amount of energy generated or used over time.

This distinction is important when interpreting solar data.

2. Daily, Monthly and Annual Generation

Historical information is arguably more useful than simply seeing today’s output.

Many monitoring platforms allow you to compare generation over different periods. Tesla, for example, allows compatible users to view energy data by day, month, year and lifetime.

This can help you understand seasonal performance.

A system will normally generate substantially more electricity during brighter summer periods than during short winter days.

3. Solar Self-Consumption

Some monitoring systems can show what happened to the electricity generated by your panels.

For example:

Solar generation → Home → Battery → Grid

Understanding this energy flow can be extremely useful.

If your panels generate 20kWh but your household only uses 6kWh directly, a significant amount of the remaining energy may need to be stored or exported, depending on your system.

4. Grid Imports and Exports

More advanced monitoring can show how much electricity you are importing from and exporting to the grid.

This is particularly useful if you have a battery or an electricity tariff where the timing of imports and exports affects your costs.

5. Battery Monitoring

If you have battery storage, your app may show:

• State of charge
• Charging rate
• Discharging rate
• Energy charged
• Energy discharged
• Solar charging
• Grid charging
• Energy supplied to your home

GivEnergy’s app, for example, provides visibility of solar, battery and grid usage and allows users to monitor charging and discharging.

Things to consider

The app is designed around SolarEdge equipment, so it is not a universal monitoring application for every solar installation.

GivEnergy App

Best for: Homes combining solar PV with battery storage.

The GivEnergy app provides a live overview of solar generation, household demand, battery operation and grid imports or exports. Its dashboard can also show daily energy summaries and comparisons with previous days.

The platform is particularly useful for homeowners who want to understand how their battery is changing the way they use electricity.

Tesla App

Best for: Tesla solar and Powerwall users.

The Tesla app provides solar generation and energy-flow information for compatible systems. Historical data can be viewed over different periods, and users can examine how energy is moving between solar generation, the home, battery, vehicle and grid.

Tesla also allows compatible users to export their energy data as a CSV file for further analysis.

myenergi App

Best for: Homes using solar alongside an EV charger and other myenergi equipment.

The myenergi app can display generation, consumption and energy flows while integrating compatible devices such as zappi, eddi and libbi. It is particularly attractive for households looking to manage several energy technologies through one ecosystem.

Which Solar Monitoring App Should You Choose?

There is an important rule to remember:

Choose your solar equipment first, then assess the monitoring platform that comes with it.

Do not select an inverter purely because its app looks attractive.

The quality of the overall installation matters considerably more than the appearance of a smartphone dashboard.

When comparing systems, consider:

1. Compatibility – Does the app work with your inverter, battery and meter?
2. Data accuracy – Does it provide the information you actually need?
3. Historical reporting – Can you compare days, months and years?
4. Energy-flow information – Can you see where your electricity goes?
5. Fault notifications – Will the system alert you to potential problems?
6. Battery integration – Can you monitor charging and discharging?
7. EV integration – Can you coordinate solar generation with EV charging?
8. Ease of use – Can everyone in the household understand the information?

How to Read Your Solar Generation Data

A monitoring app is only useful if you understand what the numbers mean.

Suppose your app shows:

Solar generation: 18kWh

That does not necessarily mean you have reduced your electricity bill by the value of 18kWh.

Some of that electricity may have been:

• Used directly in the property
• Stored in a battery
• Exported to the grid
• Lost through system inefficiencies

The financial value of each unit therefore depends on how the electricity was used.

This is why monitoring generation alone is not enough. Understanding consumption and energy flows provides a much more complete picture.

Can a Solar Monitoring App Help Reduce Energy Bills?

Yes, although the app itself does not reduce your bills.

Instead, it provides information that can help you change how you use electricity.

For example, if you discover that your solar system regularly produces significant excess electricity between late morning and early afternoon, you could consider running suitable appliances during that period.

Homes with EV chargers can potentially use surplus generation to charge an electric vehicle, while homes with batteries can store some of the electricity for later use.

myenergi, for example, provides real-time energy information and controls designed to help households optimise how renewable energy is used.

How to Choose a Solar Monitoring System

1. Start With Your Property

Consider:

• Annual electricity consumption
• Number of occupants
• Daytime electricity usage
• EV ownership
• Existing battery storage
• Future battery plans
• Roof size and orientation

2. Decide What You Want to Monitor

If you only want to know how much your panels generate, basic inverter monitoring may be sufficient.

If you want detailed information about your entire home energy system, look for monitoring that includes:

• Generation
• Consumption
• Battery
• Grid import
• Grid export

3. Think About the Future

Your energy requirements may change.

You might later add:

• A battery
• EV charging
• An air source heat pump
• Smart heating
• Additional solar capacity

Choosing equipment that can integrate with your future energy system can be more valuable than choosing the cheapest monitoring option today.

Can You Monitor Solar Panels Without an App?

Yes.

Some systems provide information through the inverter or battery display, while others use web-based monitoring portals.

However, an app or online portal is generally more convenient because it can provide historical information and allow you to check the system remotely.

GivEnergy, for example, provides both an app and a web-based monitoring portal for compatible systems.

How Much Does Solar Monitoring Cost?

In many cases, monitoring is included with the inverter or wider solar installation rather than being purchased as a separate service.

The exact arrangement depends on the manufacturer and equipment.

Additional monitoring hardware may be required if you want information that your existing inverter cannot provide.

This is why it is worth asking your installer:

• Which app comes with the system?
• Is there a web portal?
• Is monitoring included?
• Is additional hardware required?
• How long is data retained?
• Can data be exported?
• What happens if the internet connection fails?

Monitoring is generally easier and cheaper to incorporate during installation than to retrofit later.
