How to convert solar energy into electrical energy?


Question:
i want information about solar energy based roadbridge light controller using microcontroller

Answer:
Solar energy is a one of the types of energies available naturally.
This solar energy is available from the sun's rays.We can transfer them to electrical energy.This is stored in batteries and in turn utilised.Before giving you a brief answer to you i want to know what are you doing in your life.If you are an engineering graduate then the above given explanations would not be enough for you.Basically solar energy s converted into electrical energy in two methods.One of the methods is ELECTROMECHANICAL conversion and the other is PHOTOVOLTAIC conversion.In the first cases the solar energy from the sun is made to run the prime mover of the generator.From this inturn the required power is obtained.In the other method the sun's rays are directly stored in the photovoltaic batteries and then utilised.These are only the basics and for further references refer certain books.
solar energy can be converted into electrical energy by the use of solar panels.These panels when r kept in contact with sunlight get heated up thus causing a unidirectional flow of electrons which is current...
