Which Panel Is Right for Your Project?
Residential Rooftop — Runergy 405W or 450W, Talesun 445W
For standard residential installs, the Runergy 405W is a proven P-Type PERC bifacial module at a competitive price point. If your customer wants better long-term degradation performance, step up to the Runergy 450W N-Type — N-Type cells are more resistant to light-induced degradation and maintain higher output over the panel's lifetime. The Talesun 445W is another solid residential option with bifacial gain in the right installation.

Commercial Arrays — Talesun 540W, 590W or Thornova 585W
For commercial rooftops, ground mounts, and carports where reducing panel count and BOS costs matters, high-wattage modules are the right call. The Talesun 540W and 590W deliver proven commercial performance at competitive pricing. The Thornova 585W N-Type offers the added benefit of N-Type cell technology for lower long-term degradation on a 25–30 year commercial installation.
