At Droneview.be, we regularly inspect older solar panel installations to detect defects and efficiency losses. However, we recently encountered an unexpected issue at a client’s site: a brand-new installation from November 2024 had three panels with faulty cells. This proves that testing is not only essential for older systems but also for new installations.
Defects in new panels: how is this possible?
Although you’d expect new solar panels to work flawlessly, defects can occur during manufacturing, transport, or installation. The three defective panels in this installation had damaged cells, which can lead to:
- Reduced energy output: A single defective panel can negatively impact the entire string’s performance.
- Higher internal resistance and heat buildup: This can shorten the panel’s lifespan and pose safety risks.
- Potential warranty issues: If defects are not detected in time, claiming warranty replacements can become more complicated.
How we detect defects
At Droneview.be, we use thermal drone inspections to quickly and accurately identify defective cells and other issues. In this case, our thermal images clearly revealed the faulty cells. Thanks to our report, the client was able to inform the installer of the issue, who then took the necessary steps under warranty to replace the defective panels.
Why testing your new solar panels is a smart move
- Warranty and claims: An inspection right after installation provides proof if something is wrong.
- Maximum efficiency from day one: Early detection ensures your system operates optimally.
- Prevention of long-term problems: Defective panels can cause bigger issues over time.
