Solar Technologies going to be Cheaper
Molten Salt Storage Technology.
A company called Novatec Solar recently commissioned a promising energy storage solution for solar PV systems using a molten salt storage technology. The process uses inorganic salts to transfer energy generated by solar PV systems into solar thermal using heat transfer fluid rather than oils as some storage system have. The result is that solar plants can operate at temperatures over 500 degrees Celsius, which would result in a much higher power output. This means that costs to store solar would be lowered significantly and utility companies could finally use solar power plants as base load plants rather than to meet peak demand during prime daylight hours.By 2020, solar technologies could account for a significant portion of global power generation, helping economies and businesses guard against rising energy costs and the impact of climate change. However, finding opportunities to further reduce the cost of solar technologies will be key to unlocking this potential. Because polysilicon, the primary raw material used by solar module manufacturers, is the single largest cost in the solar supply chain, it represents the most significant opportunity for cost reduction. Over the next several years, new lower-cost methods of polysilicon production will commercialize, providing the solar industry with a more affordable source of raw material. In turn, these cost improvements will trickle down throughout the solar supply chain, accelerating the adoption of solar energy around the world and helping the industry realize its global potential
