HARVESTING AND USE OF SOLAR ENERGY

1. Harvesting Of Solar Energy
Presentation By : Aman Kumar (49) | Raman Kumar(B-50) | Thotakura Bhavya(B-51)|

2. What is Solar Energy
• Radiant Heat and Light from Sun
• Important source of Renewable Energy
• Why Radiations are being called as Energy ?
• Its is because Energy can neither be created nor destroyed. It can only be
converted from one form to another.
• What are the forms in which solar energy can be converted ?
• Electrical Energy , Thermal Energy, Agriculture etc.

3. SOLAR CELLS SOLAR HEATERS

4. Conversion Of Solar Energy To Electrical Energy
1: Solar panels collect sunlight.
Every solar panel contains something photovoltaic cells. PV cells take light and turn the light into electricity. When
sunlight hits the solar panel, PV cells get to work by producing (DC) electricity. This is all fine and well, but DC
electricity can’t power your home. That’s where some other pieces of equipment come into the picture.
2: Inverters convert the power to usable electricity
On the back of each solar panel there is an inverter which converts DC electricity to alternating current (AC) electricity
3: Electricity flows into net meter
AC electricity flows from the solar panels through efficient wires and cables into your net meter. Your net meter
measures both the power you’re drawing from the grid and the excess power your solar panels are putting back onto the
grid.
4: Fire up the toaster
After electricity runs through your net meter, it makes itself comfortable in your home and powers all of your appliances.
If your solar panels don’t produce enough energy to cover all of your needs, don’t worry. You’re still connected to the
power grid, so you can automatically draw more energy whenever you need.

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

15. Some Major Solar Power Plants in India
1.Bhadla Solar Park, Rajasthan
Bhadla Solar Park near Jodhpur district of Rajasthan is the largest solar park in India, spread over a total area
of 10,000 acres. The park has total capacity of 2,255 MW and NTPC announced that it had commissioned
115 MW on 22 February 2017.
2. Kamuthi Solar Power Project, Tamil Nadu
Kamuthi Solar Power Project is the largest single location solar power plant in the world, located at Kamuthi
in Tamil Nadu. The Kamuthi solar plant the world’s largest solar power plant with a capacity of 648 MW
commissioned by Adani Power
3. Sakri Solar Plant, Maharashtra
Sakri Solar Power Plant is the largest solar power plant in Maharashtra, located at Dhule district in
Maharashtra. The 125 MW ShivajinagarSakri solar plant is also one of the largest of its kind solar projects in
the country.
