Commercial Solar Project Sourcing

PES Supply is the distribution arm of PES Global. We source from 300+ manufacturers across three continents and ship through Portlandia Logistics using 14,000+ vetted carriers. Here's how we support commercial solar projects.

What We Source

  • Solar panels (Tier 1 manufacturers, commercial-grade 400W+)

  • Commercial inverters (string, central, and hybrid — 10kW to 1MW+)

  • Battery energy storage systems (BESS)

  • Racking and mounting systems (roof, ground, and carport)

  • Electrical components (combiner boxes, disconnects, conductors, conduit)

  • EV charging infrastructure

  • Generators and backup power
