1. SOLAR ENERGY

2. VIGNAN INSTITUTE OF TECHNOLOGY AND MANAGEMENT Seminar on “SOLAR ENERGY" Name: “SURAJ SAHU’’ Registration No.:2101301016 Under the Guidance of “Asst. prof. RAJASHREE PANDA" Department of CIVIL ENGINEERING

3. CONTENT: INTRODUCTION TYPES OF SOLAR ENERGY ADVANTAGE DISADVANTAGE CONCLUSION

4. WHAT IS SOLAR ENERGY ? Solar energy is defined as the transformation of the energy that is present in the sun Solar energy is the energy obtained by capturing heat and light from the sun

5. WHY WE NEED SOLAR ENERGY? Reducing greenhouse gas emissions and mitigating climate change Approximately 80% of the total amount of energy used in globally each year comes from the fossil like petroleum, natural gas and coal If we do not reduce consumption, we will run out of them, very quickly .in this case very quickly means maybe our lifespan Fossil fuel combustion results in pollutants that contribute of land degradation Fossil fuels Produce Hazardous air pollutants , including sulfur dioxide, nitrogen oxide, carbon monoxide and Mercury ,all of which are harmful to the environment and human health

6. HOW DOES SOLAR ENERGY WORK? Solar panels convert sunlight into electricity using photovoltaic cells These cells are made from semiconductor materials, like silicon. When sunlight hits the cells, it creates an electric current The direct current (DC) electricity is then inverted into alternating current (AC) for household use.

7. SOLAR ENERGY USED FOR OUR DAY-TO- DAY LIFE Solar powered ventilation fans Solar water heater Solar room heater Solar powered pump Charging batteries with solar power Solar energy for cooking Solar energy for outdoor lighting

8. TYPES OF SOLAR ENERGY There are 5 types of solar energy 1.Passive solar energy 2.Active solar energy 3.Solar thermal energy 4.photovoltaic solar energy 5.Concentrated solar energy

9. 1. PASSIVE SOLAR ENERGY Passive solar energy  involves using sunlight directly, without any additional processing. It’s all about clever architectural design that optimizes the position and dimensions of various building elements, such as walls and windows.

10. 2. ACTIVE SOLAR ENERGY Active solar energy is defined as energy from sunlight that is used to directly generate electricity through a device, like solar panels. Example- solar water heating system, solar thermal powers plant

11. 3. SOLAR THERMAL ENERGY Solar thermal energy is a technology for harnessing solar energy to generate heat. This heat can be used for a variety of purposes, including: Heating water for domestic use (showers, baths, dishwashing) Heating buildings Industrial processes Generating electricity

12. 4. PHOTOVOLTAIC SOLAR ENERGY (PV) Photovoltaic solar energy refers to the technology that converts sunlight directly into electricity using solar cells. These solar cells are typically made of semiconductor materials, such as silicon, which generate an electric current when exposed to sunlight.

13. 5. CONCENTRATED SOLAR ENERGY : Concentrated solar energy, also known as concentrated solar power (CSP), is a technology that harnesses sunlight to generate electricity. Unlike photovoltaic (PV) Concentrated solar power (CSP) is a type of solar technology that uses mirrors or lenses to concentrate a large area of sunlight onto a receiver. The concentrated sunlight is then used to heat a fluid, which drives a turbine to generate electricity.

14. ADVANTAGE : Renewable energy source Reduces electricity bills Low maintenance costs Technology development Reduces the use of fossil fuels Increases home value Environmental Pollution free In this slide i5 night the contribution of 280

15. DISADVANTAGES : The initial cost of purchasing solar system is fairly high Weather dependent Solar energy storage is expensive Uses a lot of space Time consuming Associated with pollution

16. CONCLUSION : So We can say that solar energy is a clean, pollution free and renewable source of energy To fulfills the increasing energy demand the people. Saving of land, this project is very successful one. The extra energy can be provided to the grid
