When evaluating solar investments, the focus is often on upfront costs and energy yield. However, as the industry matures, the end-of-life value of panels is becoming a critical financial consideration.
Single-Glass Panels: The Current StandardSingle-glass modules dominate the existing market. Their recycling value primarily lies in the
silicon, silver, and copper they contain. While recycling infrastructure is well-established for these panels, the process is complicated by the need to separate the aluminum frame and the plastic backsheet, which adds cost and reduces overall material purity.
Double-Glass Panels: The Future of High-Value RecyclingDouble-glass (bifacial) panels are engineered for longevity, but their true financial secret lies in their recyclability.
- Pure Glass Value: Without an aluminum frame or plastic backsheet, the glass can be easily recovered and fully reused.
- Higher Purity Metals: The simplified structure allows for more efficient extraction of valuable metals like silver and copper.
The VerdictWhile single-glass panels are easier to recycle today due to market familiarity,
double-glass panels are poised to deliver higher residual value tomorrow. For investors, choosing double-glass isn't just about better performance—it’s about securing a cleaner, more valuable exit strategy for your solar assets.
