Now Today's scenario Solar energy getting more popular in Clean & Green energy field, but by insolation Earth receives Lacs of TW since its evolution then why it becomes popular today?
Let’s Have Look to “Photovoltaic Effect”
When the sunlight or any other light is incident upon a material surface, the electrons present in the valence band absorb energy and, being excited, jump to the conduction band and become free. These free electrons which generates an electromotive force and light energy is converted into electric energy.
In similar fashion now all emerging country is now able to receives financial help from world’s leading Bank under Clean Development Mechanism (CDM) or new Market Mechanism/carbon credit Market or cap & trade scheme across the world. Which creates lot of opportunities for Renewable Energy Field. Every emerging country had shown great interest for clean & Green Renewable energy. Hence best to opt for solar energy.
Challenges & opportunities
At present CDM is facing crisis due to Global Financial turbulence. With decreasing CER & interest is also showing less by developed country. No of Project registered under CDM is also declining. Demands for CER (Certified emission reduction) is expected to remains low.
With increasing uncertainties across the world it is very challenging task to handle Global warming.
Hence almost all Emerging countries runs for renewable energy technology. So it is best to go for “Solar Energy”. India’s plan to install 100 GW from solar Power, 60 GW from wind, 10 GW from biomass and 5 GW from small hydro power projects by 2022. india is second highest position in registering projects under CDM.
For achieving such large target, Indian Government initiated Incentives for new comers in this field. Most ambitious programme of the Indian government is the “Development of Solar Cities Programme” & solar Parks under which many projects have been already approved.
As Solar Power is best & easiest to install, so Topic covered only Solar Power.
So now let’s know the kind of solar Power option available:
A. Photovoltaic solar (PV)
B. Concentrated solar power (CSP)
First one is direct type & second is indirect type. PV requires solar Modules for conversion of solar energy to electric energy through the photovoltaic effect.
Typical Solar PV Block Diagram
Silicon is the most popular material for solar cells though which solar modules & solar Panels.
Types of silicon used for solar cells are
A. Monocrystalline or single crystal silicon
B. Multicrystalline silicon
C. Polycrystalline silicon
D. Amorphous silicon.
Solar modules use light energy from the sun to generate electricity through the photovoltaic effect. The majority of modules use wafer-based crystalline silicon cells or thin-film cells based on cadmium telluride or silicon. Solar Modules is made from Solar Cells.From Combination of Solar Modules, solar Panels can be structured.
Concentrating Solar Power (CSP) systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. The concentrated heat is then used as a heat source for a conventional power plant, but CSP is less popular.
Roof based PV & Grid connected solar Power is growing very fast because of its low installation time & lesser complexity. Indian Government is helping for implementation of solar Roof Top widely across India. A total of 3030 MW Of grid-connected power generation capacity from renewable energy sources like solar and wind has been added so far this year. With increasing demand of power & decreasing Natural resource of coal & Gas, it is better to utilize the solar energy & save the Earth from global Warming.
