Solar Panels

  1. A solar power plant is based on the conversion of sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power (CSP).
  2. Concentrated solar power systems use lenses, mirrors, and tracking systems to focus a large area of sunlight into a small beam.

PHOTOVOLTAIC SOLAR TECHNOLOGY

Solar On Grid

On-Grid Systems are solar pv systems that only generate power when the utility power grid is available.

Solar Off Grid

Off-grid solar power Plant is system with battery Bank, this type of power plants also stores DC electricity in batteries bank provided with the system.

Solar Hybrid

Hybrid Solar System or Power Plant is a combination of both above said solar systems.

Solar thermal technology

  1. which captures the sun’s heat. This heat is used directly or converted into mechanical energy Sum of the potential energy and kinetic energy of an object or system and in turn electricity, known as concentrated solar power.
  2. This heat is used directly (low temperature solar thermal) or converted into mechanical energy and in turn electricity (concentrated solar power – CSP).

Main Components

Solar Panels

It is the heart of the solar power plant. Solar panels consists a number of solar cells. We have got around 35 solar cells in one panel. The energy produced by each solar cell is very small, but combining the energy of 35 of them we have got enough energy to charge a 12 volt battery.

Solar Cells

It is the energy generating unit, made up of p-type and n-type silicon semiconductor. It’s the heart of solar power plant.

Battery

Batteries are used to produce the power back or store the excess energy produced during day, to be supplied during night.

D.C. to A.C. Converter (Inverter)

Solar panels produce direct current which is required to be converted into alternating current to be supplied to homes or power grid.

Main Components

Usage solar energy

  1. As heat for making hot water, heating buildings, and cooking.
  2. To generate electricity with solar cells or heat engines.
  3. To take the salt away from sea water.
  4. To use sun rays for drying clothes and towels.
  5. It is used by plants for the process of photosynthesis.

Advantages of Solar Energy

  1. Renewable Energy Source.
  2. Reduces Electricity Bills.
  3. Diverse Applications.
  4. Low Maintenance Costs.
  5. Technology Development.
