Solar monitoring is the process of tracking how a solar energy system is performing over time. It uses software, often accessed through a mobile app or web portal, to show how much energy your system is producing, how it’s operating, and whether it’s performing as expected.

Most modern solar systems include built-in monitoring that provides near real-time visibility into system performance.

How solar monitoring works

Solar monitoring systems collect data from your solar equipment, typically through the inverter, and translate it into usable insights for homeowners.

Monitoring platforms analyze system performance by comparing expected energy production with actual output and environmental conditions like sunlight and temperature.

This data is then displayed in a dashboard or app, allowing you to:

• View energy production over time

• Track system performance trends

• Identify potential issues or downtime

Some systems provide basic system-level data, while others offer more detailed insights down to individual panels.

What solar monitoring tracks

The exact features vary by system, but most solar monitoring platforms track:

• Energy production (how much electricity your system generates)

• System performance compared to expected output

• Historical trends and daily patterns

• System status and alerts

More advanced monitoring may also include consumption tracking, helping you understand how your home uses energy alongside what your system produces.

Why solar monitoring is important

Monitoring plays a key role in maintaining system performance over the long term.

According to the U.S. Department of Energy, tracking performance metrics like system availability and output helps ensure solar systems continue operating efficiently and reliably over their lifespan.

By monitoring your system, you can:

• Detect issues early, such as reduced output or equipment faults

• Ensure your system is operating as expected

• Maintain long-term performance and reliability

• Better understand how your energy is generated and used

Without monitoring, it can be difficult to know if your system is underperforming or requires service.

Solar monitoring and mobile apps

Many solar monitoring systems are accessible through mobile apps, making it easy to check your system from anywhere.

For example, solar providers may offer an app experience that allows you to:

• View real-time energy production

• Track historical performance

• Receive alerts if your system needs attention

In systems supported by Sunrun, homeowners can use the Sunrun app to monitor their system’s performance, helping provide visibility into energy production and system status in one place.

Takeaway

Solar monitoring gives homeowners visibility into how their system is performing day to day and over time. By tracking production, identifying issues early, and supporting long-term performance, monitoring is an essential part of maintaining a reliable solar energy system.
