The efficiency of solar panels degrades over their lifespan. You can check the voltage output and compare that reading to the original output of the panel. Expect that average degradation is around 1/2 of a percent per year. If the panel is ten years old, a natural degradation would be 5 percent below its original output.
In some cases, a bad solar panel may also cause your inverter to display an error message. To determine if a solar panel is bad, look for signs such as decreased energy production, physical damage or discoloration, hot spots, potential-induced degradation (PID), and monitoring system alerts.
If you test your solar panels, you can have a clear idea of how much you can expect to save for the month. What’s more, it’ll help you identify an issue with your setup. With regular testing, you can detect drops in energy production, which can be a sign of broken or faulty components.
Because most homeowners install solar photovoltaic (PV) panels for the financial savings, the most obvious way to determine whether your panels are working is to look at your utility bill. If this month’s statement is significantly higher than last month’s – you know something is wrong. It makes intuitive sense.
If you encounter an issue with the values during your test, you may want to check the following: The solar panel should be clean and free from dust. Ensure you do your test in full sunlight without any obstructions. Angle the solar panel towards the sun at the correct pitch. If the weather is bad, redo the test on a clearer day.
The mount or frame looks bent. Damage to the wiring is visible. The inverter is showing an error message. Solar panels are prone to breaking because they’re exposed to extreme temperatures. One way to test them is with a multimeter. It can measure current, resistance, and voltage accurately. You can get multimeters in analogue or digital form.
