The growing demand for solar energy shows us why renewable energy is the next big thing. With solar panels selling like hotcakes in the market, more and more people begin to realize the beauty of harnessing the power of the sun. Let’s take a look at solar energy by understanding the concept, its process, and its benefits to the human race.
Understanding Solar Energy
Solar energy is power from the radiation of the sun. As a naturally occurring nuclear reactor, the sun can provide the energy needs of the planet. Unlike with non-renewable energy, the energy we get from sun does not decrease. According to studies, it will last us for billions of years or until the sun is alive.
How It Works
The energy is captured by solar panels placed on the roof of a building or structure. These panels are systematically positioned to effectively catch the sun’s radiation. The solar panels are composed of photovoltaic cells that convert the sun’s radiation into direct current (DC) electricity during the day. The inverter converts the direct current electricity into alternating current (AC) electricity. Once converted, the inverter sends the AC electricity to the electrical panel of your system to power the appliances and lights in your home.
A utility meter is installed for you to monitor your energy use. There are different types of systems used for converting, using, and storing solar energy in residential buildings today. The three types of residential power systems are grid tied, grid tied with battery for power backup and off-grid. Depending on your budget, you can store the accumulated energy in batteries to stay off-grid at night. If you have a smaller budget, a grid inter-tied system is a low-cost solution to your energy problem.
