How to read the table

$/W is the price-per-watt — the canonical solar value metric. Below $0.20/W is excellent (Tier-1 distributor B2B pricing on Trina, JA Solar, Longi N-type residential modules in 2024-2025); $0.20-0.40/W is the typical EU residential installer-channel range; above $0.40/W you're paying for premium (Aiko ABC efficiency leadership, premium warranties) or a portable/12V form factor that sacrifices $/W for convenience.

Efficiency is the percentage of incident solar energy the panel converts to electricity at standard test conditions (1000 W/m², 25°C). 21% is the modern PERC floor; 22-23% is the N-type TOPCon mainstream; 23-24% is the current efficiency frontier (Aiko ABC, premium HJT). For most EU residential roofs, picking 22.3% (Trina/JA/Longi N-type) over 23.6% (Aiko ABC) saves ~30% on $/W with only 5% loss in annual kWh — usually the right trade-off. The exception is roofs where every kWh from the same area matters (small urban rooftops, shading-prone sites).

Cell type matters more than efficiency for longevity. N-type cells (TOPCon, HJT, ABC, HPBC) have lower light-induced degradation (~1% in year-one vs 2-3% for PERC), better temperature coefficient (typically -0.29%/°C vs -0.34%/°C for PERC), and longer performance warranties (25-30 years to 84-89% capacity vs 25 years to 80% for PERC). Most new launches since 2023 are N-type; PERC inventory is winding down through 2025-2026.

Bifacial panels generate from both faces. On a white-roof or ground-mount install, the rear face collects 5-15% additional energy from albedo reflection. On a typical dark-shingled rooftop, the bonus drops to 1-3% — usually not worth the slight $/W premium and weight. We tag bifacial panels in green so you can see them at a glance.

Warranty shown is the performance warranty (years to a stated minimum capacity, typically 80-89%). Modern Tier-1 N-type panels carry 30-year linear performance warranties (84% at year 30 is the common spec). Product warranty (defects in materials/workmanship) is typically 12 years on PERC and 25-30 years on N-type — the difference is real, not marketing.
