About 420W Solar Panels

420W solar panels offer high-efficiency monocrystalline performance for residential and small commercial installations. These panels push the boundaries of standard 60/120-cell formats, delivering more watts per square foot for tighter roof spaces and maximum energy harvest.

Each module is UL 1703 certified with a 25-year performance guarantee. PES Global Group offers competitive pricing, fast shipping from our Louisville, KY operations, expert technical support from our product team, and bulk pallet ordering for contractors and EPCs.
