The Jinko Tiger Neo 435W wins this head-to-head comparison, taking 3 out of 5 categories. It's the stronger choice for most homeowners, especially those who prioritize lowest cost per watt in our lineup. That said, the Silfab SIL-420 BG Elite 420W is still a solid product and may be the better pick if you specifically need homeowners who want american-made panels.

Jinko Tiger Neo is our budget champion. Same N-type TOPCon tech as panels costing 30% more. Compact residential form factor installs just like the Canadian Solar. We use Jinko when the customer is cost-focused and wants the most watts per dollar. Excellent supply chain — Jinko ships more panels worldwide than anyone.
Silfab is our American-made pick. The panels are slightly lighter than Q CELLS, which crews appreciate on steep roofs. The X-pattern backsheet technology gives solid efficiency without N-type cell costs. We recommend Silfab especially for commercial projects where the domestic content ITC adder adds real savings. Reliable supply chain — no tariff or FEOC concerns.
