ESTIMATION OF SOLAR ENERGY FOR STREET LIGHTS IN VIT
ABSTRACT
A solar lighting system which can make a 18x3 w lamp glow continuously for about (7) hours if the battery is fully charged has been constructed. Here, solar energy is collected with the aid of a solar panel and thus, a battery is charged during day time with the help of a simple charging circuit. During night time, this stored energy is used to light. The device can be used for small-scale lighting applications in remote areas that are far away from the power grid. The system has a panel to collect the sun’s energy, a battery to store that energy and a light source to use the energy. The system operates like a bank account. Withdrawals from the battery to power the light source must be compensated for by commensurate deposits of energy form the solar panels.

INTRODUCTION
Electricity is becoming costly every day; so many people are getting interested in using solar energy to fulfil their electricity needs. Power cuts and dependency on Generators is making people look for better sources. Solar Photo Voltaic panels provide a very good alternative way to fulfil their demand. Ministry of New and Renewable Energy (MNRE), Government of India is also promoting solar PV systems under the Jawaharlal Nehru National Solar Mission (JNNSM) in our country. They also provide subsidise solar panels under this scheme. There are so many people, interested in buying solar panels in India so we thought of doing a research on price of solar panels. Below is our research on price of solar panels:
As per our resources from the solar PV industry, cost of a PV module (just the panel) costs anywhere between Rs 30 to Rs 60 per watt of power generated. A good imported module will cost around Rs 40-45 per watt. Good ones manufactured in India would come as low as Rs 30-32 per watt. This is to be noted that this is the cost for

Montaigne

...1575 ESSAYS by Michel de Montaigne translated by Charles Cotton I. OF CUSTOM, AND THAT WE SHOULD NOT EASILY CHANGE A LAW RECEIVED. HE seems to have had a right and true apprehension of the power of custom, who first invented the story of a countrywoman who, having accustomed herself to play with and carry, a young calf in her arms, and daily continuing to do so as it grew up, obtained this by custom, that, when grown to be a great ox, she was still able to bear it. For, in truth, custom is a violent and treacherous schoolmistress. She, by little and little, slily and unperceived, slips in the foot of her authority, but having by this gentle and humble beginning, with the benefit of time, fixed and established it, she then unmasks a furious and tyrannic countenance, against which we have no more the courage or the power so much as to lift up our eyes. We see her, at every turn, forcing and violating the rules of nature: "Usus efficacissimus rerum omnium magister." I refer to her Plato's cave in his Republic, and the physicians, who so often submit the reasons of their art to her authority; as the story of that king, who by custom brought his stomach to that pass, as to live by poison, and the maid that Albertus reports to have lived upon spiders. In that new world of the Indies, there...
