When considering the purchase of used solar panels, it's crucial to gather essential information. Below are ten questions that will guide you through the process.
1. What is the Age of the Panels?
Older solar panels may have decreased efficiency. Check the manufacturing date to gauge their age and potential lifespan.

Inspect the panels for any physical damage such as cracks, discoloration, or corrosion. A thorough visual inspection can reveal a lot about their condition.

Ask the seller for performance data or testing results, which will show how much electricity the panels generate compared to their original specifications.
