460-549W Solar Panels

Not always, but measure first. Large-format 500W+ modules can be 7.5 feet long and 50+ lbs, which complicates layout around vents and setbacks. For most shingle roofs, 400-450W panels layout more efficiently; for garages, barns, and ground mounts, the big modules win on $/W.

All three are high-efficiency mono technologies. PERC is the proven value standard (~21% efficiency). TOPCon N-type adds a percentage point or two and degrades slower. HJT (like REC's Alpha line) tops the efficiency charts at 22%+ with the best low-light and heat performance — at a premium price.

Per-panel pricing drops meaningfully at full-pallet quantity, and freight cost per panel is far lower than shipping small batches. A pallet of 500W-class panels typically holds 31-36 modules — enough for a 16-18kW system. Contractors: ask about multi-pallet and truckload pricing.

Panels in this size class ship LTL freight, palletized, with curbside delivery. Liftgate service is available if you don't have a forklift or dock. Freight is quoted at checkout for most orders, or by our logistics team for multi-pallet orders.

This class carries the strongest warranties in the industry: REC offers 25-year product warranties on Alpha series, and most N-type TOPCon modules carry 25-30 year linear performance guarantees with first-year degradation under 1.5% and around 0.4% per year after that.
