Building Utility Scale Concentrated Solar Thermal Power the “Indian way”
With the New Solar Mission ambitious goals that the Indian Ministry of New and Renewable Energy brought out on the 25th of July stipulating hard budgeting restrictions per MW as well as a firm schedule for starting construction of plants.

Solar Heating, Solar Thermal, and Solar Hot Water Systems
Solar Heating (Solar Thermal) Systems
Using solar power to heat your water is one of the most practical and cost effective ways to harness energy from the sun. Solar thermal systems absorb the sun’s heat and use it to heat your residence’s own hot water needs. In general, the solar thermal system will easily heat water to 140ºF or higher matching the range of its traditional hot water tank counterpart. Effective systems can collect up to 70 percent of the sun’s energy that reaches them and transfer it to you.
How Solar Hot Water Heating Systems Work
In general there are two types of active water heating systems: direct and indirect.
Direct Solar Water Heating
As implied, direct systems capture the sun’s heat in collectors to directly heat a household’s water supply. The system consists of collector pipes filled with water that are linked to an insulated storage tank usually located inside a home. As the sun heats the water inside the pipes, the water flows into the storage tank. Although direct systems are more efficient that indirect ones, they require more maintenance to keep the pipes clear of mineral deposits. Direct solar thermal systems also work best in warmer climates where the system is less prone to freezing.
