As of 2026, monocrystalline panels using TOPCon or HJT cell technology lead efficiency rankings. SunPower Maxeon 6 440W achieves 22.8% — among the highest commercially available for residential use.
Bloomberg NEF Tier 1 is a bankability rating — it means the manufacturer has a track record sufficient for project finance. It does not directly indicate quality, but Tier 1 manufacturers typically have more mature quality control and are less likely to go out of business (relevant for warranty claims).
Monocrystalline panels (mono-PERC, TOPCon, HJT) consistently outperform polycrystalline in efficiency and temperature performance. The price gap has narrowed significantly — monocrystalline is the standard choice for most residential installations in 2026.
Use our System Configurator to get a precise answer. Roughly: a 2,000 sq ft US home using 900 kWh/month needs a 7–10 kW system, which is 17–25 × 400W panels. This varies by roof orientation, local sun hours, and energy efficiency.
