Summary Comparison (Efficiency and Highlights)
| Brand | Efficiency Range | Highlights | Warranty | Best For |
|---|---|---|---|---|
| Maxeon | Up to 24.1% | Highest efficiency, excellent durability | 25 years product & power | Limited space, max output |
| Aiko Solar | Up to 24.3% | Advanced ABC tech, new market leader | Emerging | Cutting-edge efficiency |
| JA Solar | ~23% | Affordable, reliable, multi-busbar tech | 25 years typical | Value with high efficiency |
| REC Group | 22.2%-22.6% | Great value, low temp coefficient | 25 years | Balanced cost/performance |
| Canadian Solar | 22%-23% | High power output, long warranty | 30 years | Power output & reliability |
| Jinko Solar | 22%-23.8% | High wattage, competitive pricing | 25-30 years | Strong all-around option |
Additional Considerations
- Efficiency alone should not be the sole deciding factor. Temperature coefficient, warranty length and coverage, durability under local weather conditions, and installer experience are also critical.
- Some of the highest efficiency panels (Maxeon 7, Aiko Neostar) may have limited availability or higher upfront cost.
- Panels with low temperature coefficients (e.g., Panasonic Evervolt and REC) perform better in hot climates.
- Larger-format, high-wattage panels (like Jinko Tiger Neo and Canadian Solar TOPHiKu6) can reduce installation costs per watt.
In conclusion, for 2025, Maxeon panels are generally regarded as the top choice for high-efficiency residential solar, followed closely by Aiko Solar (new and highly efficient), JA Solar, REC Group, Canadian Solar, and Jinko Solar as excellent alternatives depending on priorities like cost, climate, and power output.
