Solar Energy


Solar Energy is energy that is present in sunlight. It has been used for thousands of years in many different ways by people all over the world. As well as its traditional human uses in heating, cooking, and drying, it is used today to make electricity where other power supplies are absent, such as in remote places and in space. It is becoming cheaper to make electricity from solar energy and in many situations it is now competitive with energy from coal or oil.

After passing through the Earth’s atmosphere, most of the Sun’s energy is in the form of visible light and infrared light radiation. Plants convert the energy in sunlight into chemical energy (sugars and starches) through the process of photosynthesis. Humans regularly use this store of energy in various ways, as when they burn wood or fossil fuels, or when simply eating plants, fish and animals.

With the addition of a sun room, we’ll refer to it as a solar room, for example, the all glass room allows the daylight hour sunshine to filter in and warm the room through a collector called a transparent covering in the glass. Now, if we add plants and rocks for a nice visual, the rocks will actually store the heat of the sun and that energy can be used when the sun goes down to heat the room. Stored energy is great and has a lot of uses, like batteries for instance.

You can power your home with solar energy. The system needed isn’t that complex when you examine the devices needed. Simply add solar panels to collect sunlight and convert it into electricity. DC power (direct current) is then sent to an inverter, which converts DC power into Ac power, which now runs your home. Through the use of transfer switches and other safety devices, your clean, renewable power source is capable of powering your home, camper, cabin, tool shed, or any other building for that matter.

Lighting in your home is something we all use. With the invention of LEDs (light emitting diodes) lighting, your home can now have optimal lighting with minimal power consumption. These small, electronic light or set of lights can be connected through a battery-charged system that is powered by sunlight through the day and batteries through the night. When the sun is available, the battery charger charges the backup battery and runs the lighting. Then at night, the batteries kick in and supply the lighting while the sun is not visible.
