Revolution through Evolution

How solar PV system works

The re-framed Greek adage derives from the famous quote by Whole Gospel, “Life is a gift of God and beautiful living is an act of wisdom.”  Yes, it is true that nature gifts every living being with a gift, a gift to live, an opportunity to make a difference in this world whether positive or negative. The footprints that you leave behind defines the legacy you want your successors to follow. The legacy of adopting renewable resources of energy i.e. solar, wind, biogas etc. and save the ailing condition of our planet- 'Motherly Earth'.

Humans have contributed to the evolution to reach the apex of success that we claim today, but at the same time harming the environment with pollution whether it be air, land or water. So, to repay the debt and save the environment from further depletion, we should join our hands to adopt green energy i.e. Solar Energy. It is cost efficient and available abundantly in many regions of the earth. The fundamental technology behind this energy is solar panels which have an array of solar cells on it based on the principle of 'Photovoltaic Effect (PV)'.

Sun emits 3.86 x 10^26 watts of energy, but most of that energy goes off into space and about 1.74 x 10^17 watts strikes the earth which can be utilized. Solar PV systems use cells to convert sunlight into electricity. The bombarding energy can be termed as photons (hv) and the PV cell consists of one or two layers of a semiconducting material, usually silicon. When light shines on the cell it creates an electric field across the layers causing electricity to flow. The flow of electricity depends on the intensity of light falling on it. The PV Modules gather solar energy in the form of sunlight and convert it into direct current (DC) electricity. An inverter used, can convert this DC power into alternating current. PV Modules are joined together to form a PV Solar Panel system and can further be concatenated based upon the load.

The power generated can be stored in batteries or systems can be designed in such a way that, surplus energy goes back to the electricity grid for which you will get paid isn't that engrossing? Also, the government subsidize the setup cost and some percent of the operational cost if an enterprise or individual adopt this green fuel.

It is our wisdom that drives us to ameliorate and prospers in the finite existence that we owe to the supreme power.

I'm the guy full of awesomeness. I'm a tech freak and love to express and share my views on new invention all around the globe. I'm a seasonal peripatetic, capturing every moment .I have interest in Digital Electronics and PLD . Being an optimistic I try to tackle every problem peacefully and personally believe I either win or learn but never lose.
