“…This analysis is performed using a financial model developed by Spire's marketing and finance departments called the Investment Analysis -Commercial Model (IACM). Results obtained using IACM compares well with other results obtained in previous analyses obtained by using models such as IPEG and others (2). Actual vendor cost data is used in the analysis to obtain a realistic assessment of the cost to manufacture modules using Cz or cast silicon technologies.…”

This sensitivity analysis is conducted to show the efkct of specific manufacturing processes on the cost of making photovoltaic wafers, cells, and modules. Our analysis incorporates Spire's own intemal financial investment model. The results are compared to analyses done with the JPLoriginated PEG model (I).The manufacturing cost is broken down into costs associated with labor, equipment, overhead, materials, G&A, interest, and depreciation. A base line manufacturing capacity of 10 M W per year is used for Cz and cast silicon materials. Starting from the base line case, sensitivity analyses are performed to determine the effects of changes in the labor rate, raw material (polysilicon) cost, production volume, and cell efficiency.Preliminary results show that 53% and 28% of the module manufacturing cost are attributed to the wafers and cells, respectively. Also, it is noted that materials costs, efficiency and equipment utilization cell have a major impact on the cost of manufacturing. The results obtained support the need for higher volume manufacturing, higher automation, and better material utilization.

AbstractAmorphous silicon is a thin film option that has the potential for a cost-effective product for large-scale utility photovoltaics application. The initial efficiencies for single-junction and multijunction amorphous silicon cells and modules have increased significantly over the past 10 years. The emphasis of research and development has changed to stabilized efficiency, especially that of multijunction modules. NREL has measured 6.3%-7.2% stabilized amorphous silicon module efficiencies for U.S. products, and 8.1% stable efficiencies have been reported by Fuji Electric. This represents a significant increase over the stabilized efficiencies of modules manufactured only a few years ago. An increasing portion of the amorphous silicon U.S. government funding is now for manufacturing technology development to reduce cost. The funding for amorphous silicon for photovoltaics by Japan over the last 5 years has been about 50% greater than that in the United States, and by Germany in the last 2-3 years more than twice that of the U. S. Amorphous silicon is the only thin-film technology that is selling large-area commercial modules. The cost for amorphous silicon modules is now in the $4.50 range; it is a strong function of plant production capacity and is expected to be reduced to $1.00-1.50/Wp for plants with 10 MW/year capacities.
