Solar panels are extremely durable, designed to last at 20-25 years at the very least. During that time they are also designed to retain at least 80 percent of their original output – in fact, the industry standard for warranties is 20 years and 80 percent output. A lot of people believe, in fact, that panels can produce power almost indefinitely.
While the structure of the panel should not degrade, there are some instances where the solar cells within the panel can develop problem. The elements and chemicals that comprise the cells can deteriorate with age, just like anything else. While silicon, the material from which most solar panels is made, is extremely durable and efficient, the sun will eventually begin to have a negative effect, causing the cell to break down.
How to Check if Your Solar Panels Have Problems
- First, take a baseline reading of your system when it is first installed. There are many systems that come with software that analyzes any sudden reduction in output.
- Check the panels periodically to make sure their surfaces are undamaged, clean and there are no obstructions to direct sunlight. If you notice any reduction in output, that will very likely be a temporary problem that is easy to fix. It does not necessarily mean that your panels are wearing out.
- If you’re having an issue with output reduction, make sure the problem isn’t your inverter. In many instances, your systems solar cells will outlast the inverter.
- Check your DC electrical output to the baseline numbers. If the current numbers are substantially lower, have a professional check your system.
