Why a 25‑Year Warranty Matters in Minnesota
Minnesota's climate subjects solar arrays to extreme temperature swings, snow load, and ice formation. A comprehensive warranty protects capital investment against premature degradation and ensures that any required repairs are covered without unexpected out‑of‑pocket costs. It also signals that the installer trusts the durability of their design, a critical factor for businesses planning a 20‑ to 30‑year return on investment.
