Solar Resources

Solar resource is one of the most important factors in determining performance of solar thermal systems. Th e Southwestern United States potentially offers the best development opportunity for solar thermal electric technologies in the world. There is a strong correlation between electric power demand and the solar resource due largely to the air conditioning loads in the region. Figure 4 shows the direct normal insolation for the United States.
