What Is Solar Energy?

In order to know where to find solar energy you must first know what solar energy is. Solar energy is energy from the sun. During the day when the sun is shining solar energy is being produced as it sends the heat radiating to the earth. There is a way that you can save the sunlight in order to provide heat during the cold, which is what millions of people have done throughout the years. It started thousands of years ago when people started using a thick lens or magnifying glass on an object that would attract the sun’s rays on that particular object so it would catch fire. This gave a new perspective on how strong the heat from the sun really was.

The problem with capturing the sun’s heat is the fact that when it reaches the earth’s surface it does not go to one particular spot. It is spread evenly over the earth where the sunlight is able to reach. When this happens you may find it difficult to heat something using only the sunlight.  That is why it’s so important to have a source that focuses the sun’s rays to produce heat or light.

In order to use the heat efficiently to heat a room after the sun goes down or when the sun is unable to shine because of clouds you will need to use a source that will attract the heat to one particular area. This source is called a solar collector. The solar collector attracts a lot of sunlight to one particular area allowing the sun to pass through the source and into the space. The objects in the space absorb and hold the heat. Glass is a great solar collector because it allows the sunlight to pass through and into the space. The heat from the sun gets trapped, leaving the space under the glass warm or hot. The objects in the space help to hold the heat as it comes in, so that the space will stay warmer longer. This allows the area to be heated using solar energy.

Because glass is a natural solar collector it makes a great material to use in a greenhouse or a sun room. The sun’s rays can pass through the glass and get trapped inside so that the temperature in the greenhouse or sun room remains warm even at night when the temperature outside may be cold.
