Photovoltaic low power systems and their environmental impact: Yuma, Arizona, U.S.A. case study and projections for Mexicali, Mexico

摘要: This article presents a proposal for the implementation of photovoltaic systems in homes located Mexicali, Mexico. With exhibition new insulation and different consumption characteristics. The low power system is proposed as type electrical supply that helps reducing environmental impact generating energy by burning fossil fuels. A installed city Yuma, Arizona United States, which supplies needs to building selected reference solar resource use. Energy use improvement costs are calculated, equivalent amounts greenhouse gases, not generated since technologies were implemented determined. Furthermore, comparisons potential between Yuma Mexicali show Mexican has higher annual potential, so applicability this technology too feasible Mexicali.
