Investing in a solar photovoltaic (PV) system is a significant step toward energy savings and environmental sustainability. To ensure you maximize the return on your investment, it is essential to check that your system is consistently performing at its peak. Here's how to monitor for signs of underperformance and what actions to take if things aren't running smoothly.

Why Monitoring Matters

Solar PV systems, like any technology, can experience performance fluctuations. Regular monitoring helps you identify and address issues before they lead to significant energy losses or costly repairs. A well-monitored system ensures:

• Optimal  Energy Output: Maximise electricity generation based on local conditions.
• Increased Lifespan: Catch small issues before they become larger, extending the life of your solar system.
• Financial Savings: Underperformance can cost you in lost energy and missed savings, especially if the system isn't working at its full potential.

Common Causes of Underperformance

1. Shading Issues: Nearby trees, buildings, or even dirt and debris, bird dropping on panels can cast shadows that reduce efficiency.
2. Degradation Over Time: All panels experience some loss of efficiency over the years. Regular assessments help ensure this is within expected limits.
3. Inverter Failure: Inverters are the heart of your solar PV system, converting DC to AC. Any issues with the inverter will severely impact system performance.
4. Temperature  Effects: Excessive heat can reduce solar panel efficiency. Monitoring  systems can track if high temperatures are leading to underperformance.
5. Wiring or Connection Issues: Loose or corroded connections can lead to power loss, impacting overall system output.

How to Monitor Performance

There are a few key ways to monitor your solar PV system for underperformance:

‍

1. Use an Online Monitoring Platform

Most modern solar PV systems come equipped with monitoring tools or apps that allow you to track performance in real time. These platforms will:

• Show the daily energy production.
• System performance
• Compare expected vs. actual energy output based on weather conditions.
• Alert you of any performance irregularities, such as reduced output from  specific panels.
• Shows real-time performance metrics. If the system is underperforming, the inverter may display an error code, indicating a specific problem (such as a grid fault or a system fault).

2. Compare Energy Bills

If your energy savings aren't aligning with expectations, it could be a sign of underperformance. By tracking both your utility bills and the energy output from your solar system, you can get a clearer picture of whether or not your system is performing optimally.

3. Scheduled Maintenance and Inspections (O &M) 

While monitoring technology is a great first step, periodicprofessional inspections are key. Experts can physically assess your system,check for wiring issues, clean panels, and ensure that all components areoperating efficiently.

Steps to Take if Your System is Underperforming

If your monitoring reveals that the system is underperforming, here’s what you can do:

• Check  for shading or debris: Ensure there are no new obstructions casting  shadows on the panels.
• Contact  your installer or maintenance provider: For more complex issues, reach out to a solar professional who can diagnose and fix any problems that you may encounter. 
• Re evaluate  your system's configuration: In some cases, reconfiguring the system or adding more panels may be necessary to meet growing energy demands or     compensate for degradation.

Consistent monitoring is key to ensuring your solar PV system is performing at its best. By keeping an eye on performance metrics and scheduling regular maintenance, you can optimize energy production, save on electricity bills, and extend the life of your solar investment.

Stay proactive, and your solar system will keep delivering clean, efficient energy for years to come.
