TAN: Photovoltaic Market Saturation Is Closer Than Market Consensus
Invesco Solar ETF (TAN) is rated a strong sell due to persistent sector headwinds and market saturation risk. Despite explosive global solar PV growth, TAN underperformed the S&P 500 by 112% over five years, driven by price deflation and margin erosion. Grid adaptation, storage costs, and seasonal intermittency create structural bottlenecks, capping further solar penetration and undermining bullish forecasts.
