ABSTRACT
All life on the earth depends on solar energy. Green plants make food by
means of photosynthesis. Light is essential from in this process to take place. This
light usually comes from sun. Animal get their food from plants or by eating other
animals that feed on plants. Plants and animals also need some heat to stay alive. Thus
plants are store houses of solar energy. The solar energy that falls on India in one
minute is enough to supply the energy needs of our country for one day. Man has
made very little use of this enormous amount of solar energy that reaches the earth.
Energy from the sun is called solar energy. The Sun’s energy comes from nuclear
fusion reaction that takes place deep in the sun. Hydrogen nucleus fuses into helium
nucleus. The energy from these reactions flow out from the sun and escape into space.
Solar energy is sometimes called radiant energy. These are different kinds of radiant
energy emitted by sun. The most important are light infrared rays. Ultra violet rays,
and X- Rays.
Basically photovoltaic effect can be observed in nature in a variety of
materials, but the materials that are capable to achieve best performance in sunlight
are the semi-conductors because when photon from the sun are absorbed in a
semiconductor, they create free electron with higher energies than the electron which
provide the bonding in the base crystal. Once these electrons created, there must be an
electric field to induce these higher energy electrons to flow out of the semi-conductor
to do useful work. The electric field in most solar cells is provided by a junction of
materials which have different electrical properties.
This project is based on Construction and connection of photovoltaic module
and related theories about it. To utilize maximum energy from the photovoltaic cell
first of all understanding of it characteristics is very important because of this in
starting of project we done proper study on characteristics of photovoltaic module and
maximum power point. After got proper understanding of characteristics we try to use
output of photovoltaic cell efficiently with help of Maximum power point tracker and
cuk converter.
