Is solar a good investment?

Solar panels are one of the best investments available to UK homeowners. 100-200% ROI over 25 years (panels only). 200-400% with battery + smart tariff. Tax-free returns (SEG income and savings are not taxable). Inflation-protected (higher electricity prices = higher savings). Low-risk (generation is highly predictable from decades of data). Outperforms: Cash ISA (67%), Premium Bonds (42%), government bonds (67%). Comparable to stocks (285%) but without the volatility. You also USE the product every day — unlike a savings account.
