4 Signs Your Solar Panels Might Be Underperforming

Solar panels are a fantastic way to harness clean energy, reduce electricity bills, and contribute to a greener planet. However, like any technology, they can sometimes experience issues. If your solar panels aren’t working as efficiently as they should, catching the problem early is important to maintain optimal performance and avoid costly repairs.

Here are four signs that your solar panels might be  underperforming:

1. Lower Electricity Production

One of the most obvious signs that your solar panel is underperforming is a noticeable drop in electricity production. If your system is suddenly generating less electricity than usual, it could indicate an issue such as shading, dirt accumulation, faulty wiring or more. Regularly check your energy monitoring system to track how much electricity your panels are producing. Compare the current output to historical data, accounting for seasonal variations. If you notice a significant and unexplained decrease, it’s time to investigate further.

2. Unusual Increase in Electricity Bills

If your electricity bills have suddenly spiked, despite having solar panels, it could be a sign that your system isn’t generating enough electricity. This shortfall might force you to draw more power from the grid, leading to higher costs. Compare your current bills with previous ones to see if there’s a noticeable increase. Check for factors such as reduced daylight hours or increased electricity consumption that could explain the rise. If there are no clear reasons for the spike, your solar panels might need attention.

3. Inverter Warning Lights

The inverter is a crucial component of your solar system, converting the energy generated by your panels into usable electricity. Most inverters have indicator lights to show if everything is working properly. If you notice a red or orange light instead of the usual green, it could be a sign that there’s a problem. If you notice an unusual light on your inverter, consult the inverter’s manual for troubleshooting steps. If the problem persists, contact your installer to diagnose and resolve the issue.

4. Fluctuating Electricity Output

If your solar panel’s electricity output seems inconsistent – producing high amounts of electricity one day and very little the next – it could indicate a problem. While electricity generation can vary depending on weather conditions, large fluctuations without a clear cause might signal an issue with the system. Review your electricity generation data over time to spot any unusual patterns and investigate potential causes.

What to Do Next

If you suspect your solar panels are underperforming, it’s best to address the issue as soon as possible. Regular maintenance, including cleaning the panels and checking for damage, can help keep your system running smoothly. If the problem persists, consider contacting a professional to assess and repair your solar system.
