Installation Notes from Our Crew

Jinko Tiger Neo 435W

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 SIL-420 BG Elite 420W

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.
