By embedding a digital storefront into the design workflow, PES eliminates missed sales opportunities and accelerates revenue capture for solar distributors, reshaping the procurement landscape.
The solar distribution market has long struggled with a disjointed buying process, where designers finalize system layouts before encountering a distributor’s catalog. This gap often leads to delayed orders, price variance, and lost revenue. ProEnergy Supply’s AI‑driven gateway bridges that divide by feeding real‑time inventory data from distributors straight into OpenSolar’s design environment, turning the design tool into a transactional hub. The technology leverages machine‑learning to match bill‑of‑materials calculations with available stock, ensuring accuracy and speed.
For distributors, the integration offers a frictionless sales channel that plugs directly into existing ERP platforms such as Epicor P21, SAP, and Infor. By presenting a digital storefront within the tools solar professionals already use, PES reduces the need for manual quoting and follow‑up, slashing fixed operational costs and lowering customer acquisition expenses. The credit‑guaranteed order flow further mitigates financial risk, allowing distributors to commit inventory without fearing payment defaults. Early adopters can expect faster order fulfillment, higher conversion rates, and a clearer view of demand trends.
Industry analysts view this partnership as a catalyst for broader digital transformation across the solar supply chain. As more distributors join the OpenSolar Shop, the network effect could standardize real‑time pricing and inventory visibility, driving down overall system costs. Investors and OEMs will likely monitor the rollout closely, given its potential to reshape revenue models and improve margin predictability. The March 2026 national launch positions PES and OpenSolar at the forefront of a more integrated, data‑driven solar market.
ProEnergy Supply launches AI‑driven transactional gateway with OpenSolar
Distribution intelligence company ProEnergy Supply (PES) has officially launched its proprietary and AI‑driven transactional gateway, bridging the gap between solar system design and distributor ERP systems. Working with OpenSolar, PES enables distributors to sell equipment directly within the new OpenSolar “Shop” platform.

“Live” inventory can be viewed and now purchased by over 28,000 active solar professionals at the exact moment they are designing solar systems or reviewing automatically calculated bill of materials on a sold system.
“We’re not asking distributors to change how they operate,” said Brian C. Boguess, CRO and co‑founder of ProEnergy Supply. “Instead, we are giving them a digital storefront (transactional marketing) inside the tools their customers are already using every day. We did not build PES to add more work to your plate. We built it to reduce your fixed costs tied to the sale and to lower your customer acquisition costs.”
“I helped build some of the largest solar distributors in the industry, and I saw firsthand how much revenue is lost because distributors aren’t present when the solar professional is making a buying decision,” said Christian Siebens, CEO and co‑founder of ProEnergy Supply. “PES puts you in front of the solar professional during system design, not days after the fact. To me, that is the biggest difference between winning the sale and hoping for a call back.”
PES is currently onboarding solar and electrical distributors in key states with national rollout to follow. Distributors utilizing Epicor P21, Eclipse, SAP, Infor or other ERP systems are encouraged to apply immediately for territorial priority. PES‑partnered distributors will start to go live in the OpenSolar Shop in March 2026. Those interested in a demo can sign up online.
“The PES and OpenSolar tech‑stack strategic partnership gives distributors a huge boost to their bottom line,” said Andy Rose, Global Head of Commercial for OpenSolar. “With 28,000 solar professionals designing in our latest release with the PRO Shop functionality, PES delivers credit‑guaranteed sales orders directly into a distributor’s ERP sales queue without the associated traditional fixed costs.”
