In this type of solar power system, sun rays are focused on a small area by using mirrors or lenses. Due to this, a large amount of heat is generated at the focused area. This generated heat is used to heat the working fluid which, in turn, drives the steam turbine. There are three main types of concentrated solar power systems, namely, parabolic trough, power tower, and dish sterling system.

Advantages

 Solar power causes no pollution.

 Renewable energy resource and can produce clean power throughout the year.

 Return on investment unlike paying for utility bills.

 In case of grid connected excess power can be sold back to power company.

 Helps the economy by creating jobs for solar manufacturers and installers.

 Less safety risks.

Disadvantages

 Initial cost is high for installation and material.

 Requires additional equipment like inverter to convert dc to ac.

 Efficiency is generally low.

 Cloudy days do not produce as much energy.

 Size of the solar panels varies depending on the geographical locations for the same power generation.

 Large battery bank is needed to store the power.

Government Initiatives: Since solar energy has started to light up the lives of millions of peoples. Government has taken various initiatives to enable an increase in solar power at a subsidized energy cost. There are some top government initiatives which is listed below:

 Solar park scheme [13].

 Viability Gap Funding scheme (VGF).

 Government Yojana solar energy subsidy scheme.

 Ujjwal Discom Assurance Yojna scheme (UDAY) [13].

 Rooftop scheme.

 Jawaharlal Nehru national solar mission.
