Even though the environment is very dry, dust does not appear to be a major problem for solar photovoltaic panels in the San Luis valley. Solar photovoltaics consume very little water compared with solar thermal technologies that make steam to generate electricity. Still, SolarReserve is proposing another large-scale solar project that uses concentrating solar power and steam to make electricity. Its molten salt uses less water than other solar thermal technologies, but the company will need to secure access to water rights to be permitted.
