Before comparing brands, understand what matters:

• ✓**Efficiency:** Higher efficiency = more power from smaller roof area. Premium panels: 20–22%. Standard: 17–19%.
• ✓**Performance warranty:** 25-year linear performance guarantee (should promise at least 80% output at Year 25)
• ✓**Product warranty:** 10–12 years for manufacturing defects
