Project Brief

Project Summary: We designed, supplied and managed the construction of a 28kW Solar Energy System for Clarion University. I produced a well coordinated self ballasted mono crystalline solar PV System based upon the Solar World SW175 Module and a PV Powered 30kW PV Inverter. Working closely with Bohlin Cywinski Jackson's Structural Engineer, a distributed deadload was agreed to comply with wind uplift calculations we worked out a safe, maintenance free solution for the New Science Building.
