PV Integration in New Construction: A Comprehensive Design-Through-Operations Guide

An analysis by the National Renewable Energy Laboratory (NREL) measured that photovoltaic installations on new-construction sites required an average of 3.5 worker-hours per kW — roughly 45% less labor than the 6.4 worker-hours per kW recorded on reroofing retrofit sites. The difference is not accidental. When the structural engineer sizes steel joists for PV dead […]
