Abstract:
The oil shocks of 1970s led to spiraling crude oil prices in the world market which prompted planners to view energy security as an issue of national strategic importance. Energy security has an important bearing on achieving national economic development goals and improving the quality of life of the people. World s dependence on crude oil will continue for most part of the 21st century but the continued dependence on crude oil is loaded against it with inherent price volatility linked to finite global r ....etc

SEMINAR REPORT ON
SOLAR WATER HEATING SYSTEM WITH PHASE CHANGE MATERIAL
SUBMITTED BY
Mr. GADHAVE PITAMBAR SUBHASH



ABSTRACT
The one of the most important part of a solar collector system is the solar tank. The solar collectors work daytime only, and its power depends on the weather. The hot water consumption in family houses is generally bigger in the evening and in the morning, so it is necessary to store the utilized energy. The collectors transform but not store the s ....etc

Powerful and controllable energy source



ABSTRACT
Temperature dependent workplaces are the heart of industrial civilization. Powerful and controllable energy source are the most important demand of an industry. Boiler, heat exchangers provide this energy to these industries. The temperature of these sources must be controlled by means of controlling the heater coils or the flame so that it cannot damage complete system by excessive heating or else. Various temperature controll ....etc

ABSTRACT
Solar panel converts the light energy from the sun into electrical energy. In ordinary solar panel systems, the solar panel is fixed in a particular direction. The solar panel delivers maximum energy only when it faces directly towards the sun. Since the sun is moving continuously, the solar panel cannot deliver maximum energy when the solar panel fixed at one direction.
The goal of the project is to control the solar panel continuously, according to the moveme ....etc

ADVANCEMENTS IN UTILIZATION OF SOLAR ENERG
Presented In:
Gokula Krishna College Of Engineering, Sullurpet
Abstract:
Solar energy is an inexhaustible resource. The sun Produces vast amounts of renewable solar energy that can be collected and converted into heat and Electricity.
Solar power is the generation of electricity from sunlight. This can be direct as with photovoltaics (PV), or indirect as with concentrating solar power (CSP), where the sun's energy is focused to boil water which is then used to provide po ....etc

ABSTRACT
A solar cell is a semiconductor device that converts solar energy into electricity by the photovoltaic effect, representing the fundamental power conversion unit of a photovoltaic system ,works under the principle of a P-N junction that absorbs light , releases electrons and holes , creating a voltage in the cell , which is then applied to load; being environmentally aware, and with the price of living rising at an alarming rate, solar power, generating energy from the natural resources of the sun, has in recent times become quite a ....etc
