INTRODUCTION:
Solar Panel are designed to absorb rays from sun.
Solar Energy is main source of energy, it is renewable energy that will never never lost. So we should utilize this great energy source. There are various ways we can use this solar energy for example: we can produce electrical energy which will be use to operate electrical things, this is one time expense and enjoy free electricity all the time.
Here I have discussed which Solar Panels are best and how they make.
Solar Panel:
A Panel which is designed to absorb sun ray’s as a source of energy for generating electricity or heating, [1]
Solar panels are devices that convert light into electricity. They are called "solar" panels because most of the time, the most powerful source of light available is the Sun, called Sol by astronomers. Some scientists call them photovoltaic which means, basically, "light-electricity." [2] A solar panel is a collection of solar cells. Lots of small solar cells spread over a large area can work together to provide enough power to be useful. The more light that hits a cell, the more electricity it produces. [2]
Solar Panel Efficiency:
* Solar Panels which are in houses that convert 14% of light energy that reaches them. [3]
* DS1's solar panels convert 22% of their available energy into electrical power. [3]
* DS1's panels are so efficient, in fact, that unless the ion propulsion drive is running, DS1 is producing far more power than it needs [3]
How do solar concentrators work?
A solar concentrator uses lenses, called Fresnel lenses, which take a large area of sunlight and direct it towards a specific spot by bending the rays of light and focusing them. Some people use the same principle when they use a magnifying lens to focus the Sun's rays on a pile of kindling
