SunPower Maxeon panels are
the best residential solar panels available by every measurable metric — highest efficiency (22.8%), lowest degradation (0.25%/year), and longest warranty (40 years). For long-term homeowners with space-constrained roofs, the lifetime value of lower degradation and higher efficiency exceeds the upfront premium within 10–15 years. Not the best value for buyers with adequate roof space; the best absolute performance for those who want maximum lifetime energy production regardless of cost.
