Why New Solar Panels Lose Power: LID vs LeTID Explained

LID vs LeTID in solar panels showing the difference between light induced degradation and elevated temperature induced degradation in photovoltaic cells.

Noticed an early drop in solar output? An engineer breaks down LID vs LeTID degradation, affected cell types, and what manufacturers test for. LID and LeTID are two specific, well-documented degradation mechanisms that cause a measurable output drop in certain solar cells shortly after installation, before performance stabilizes. Neither is a manufacturing defect — they’re … Read more
