At 3Buy Solar, we’ve built a B2B pricing system for the next generation of European energy professionals—one that combines brand-authorized pricing, multi-market access, and a procurement-first structure. Our official B2B price list (available in downloadable PDF) is structured to support the daily needs of installers, resellers, online solar shops, and technical project buyers across Europe and the UK.

Unlike mass-market platforms or copycat marketplaces, 3Buy pricing is optimized for verified businesses looking for certified, bankable, and margin-friendly products across solar, battery storage, inverters, EV chargers, and heat pumps.

What’s Inside the 3Buy B2B Price List?

Our downloadable 3Buy B2B Price List (PDF) is a professionally curated document structured specifically for trade use — giving installers, resellers, EPCs, and solar retailers immediate access to brand-authorized wholesale pricing across all major product categories.

The price list is organized by product type, brand, and variant, with each section tailored to reflect real-time availability, regional demand, and project-specific deployment compatibility for the European, UK, and US markets.
