Solar panels are a great way to minimise your energy bill and your reliance on grid electricity. But while solar systems are excellent when working correctly, it can be difficult to tell when something breaks or when your panels aren’t working as efficiently as they should.
Often the first sign that your solar system isn’t working correctly is when you open your energy bill and see a higher charge than usual. The solution to this problem is a solar monitoring system that regularly tracks your systems’ performance.
But where do you get a solar monitoring system and is it worth the cost? This Canstar Blue guide has the information you need to know.

What is a solar panel monitoring system?
A solar monitoring system provides real-time information on your home solar system. A good solar monitor can tell you how individual panels are functioning and whether one or more isn’t producing as much energy as the others. This could be useful to indicate whether there’s been an electrical fault that may be causing you to miss out on energy generation.
Solar monitors can also be used to track performance over time, troubleshoot problems and track your solar investment’s financial performance.
How does a solar monitor work?
Solar monitors measure the performance of solar panels and report real-time data to help keep track of any changes and alert home or business owners to any potential issues with their solar system. The monitoring system will measure energy consumption, solar electricity production, grid imports and exports, and, if you also have a solar battery installed, its available charge and discharge power.
Some monitoring systems can tell you if a single micro-inverter fails or compare solar feed-in tariffs and alert you if there is a better option available. This information can be accessed using your computer, tablet or phone depending on whether the monitoring system uses online software or an app.
Features that may be accessible through your monitoring app or online software include:
- Solar system performance
- Household energy usage
- The amount of electricity that has been bought and sold
- Time stamps of when your system was loading energy
- Comparison of how much energy should be produced and how much is actually being produced on any given day
- Alerts and fault diagnostics
This information is designed to help customers make changes accordingly, whether it’s to get something fixed in a timely manner or change their usage to make better use of the energy generated by your system. A good solar monitor will also be able to tell you what your standby energy usage rate is so you can identify how much power is being used and take steps to reduce this.
How much does solar monitoring cost?
Solar monitoring system costs include installation fees and an ongoing subscription cost. According to Solar Analytics, out-of-pocket installation fees can range from $200 – $800 while subscription fees are generally a few dollars a month.
However, if the software alerts you to issues that would otherwise go unnoticed, it could pay for itself many times over.
Benefits of solar monitoring systems
The main benefits to installing a solar monitoring system include:
- Immediate knowledge of any issues: Rather than waiting for your next bill to tell you there may be something wrong, a solar monitoring system can immediately alert you if there is an issue, which means you can have it fixed promptly.
- Understanding your energy bill: If your most recent bill is significantly higher than anticipated, a solar monitoring system will be able to help you understand:
- where the increase came from
- whether the performance of your panels decreased
- if the household is consuming more energy
- if you’ve changed tariffs
- if there was a billing error.
- Energy consumption insights: By using a monitoring system, you’ll be able to see your own energy consumption. This allows you to be more energy efficient which may in turn reduce electricity bills.

Are all solar monitoring systems the same?
Like everything, there are some solar monitoring systems that are better than others. It is generally recommended to get a solar monitoring system from a company that specialises in that software rather than purchasing one from a solar panel manufacturer.
There are three main types of solar monitoring systems:
- Solar monitoring from equipment manufacturers
- Solar monitoring from your installer
- Standalone home energy monitors
Some companies offer solar monitoring systems with their solar inverter sales, particularly for micro inverters, but, as mentioned above, it is generally recommended to go with a standalone home energy monitor from a company that specialises in software development. If your manufacturer happens to do both, then it is a win-win.
Should I get a solar monitoring system?
Whether you get a solar monitoring system installed will depend entirely on your energy needs and budget. The system alerts you if there are any issues and allows you to track performance and your own energy usage — helping to decrease energy bills and keep your solar panels performing as they should.
That’s not to say that you can’t achieve these things without solar consumption monitoring, but it does provide just that little bit of extra security when it comes to the performance of your solar system.
