Examining the cost manufacturing advantages of ‘solar breeder’ factories for deployment in utility-s

This paper, the fourth in a series covering cost modelling studies for photovoltaics [1–3], examines a new approach to module assembly based on the concept of ‘supersized’ 1kW PV modules. Using supersized modules (1.6m × 3.8m) and integrated microinverters, this novel approach has the estimated potential to save utility solar installations nearly $0.50/Watt. The paper will conclude with a detailed cost and resource case study comparing two 40MW module lines, one employing ‘solar breeder’ technology and the other producing conventional-sized modules.
