Using Solar Energy For Green Buildings

As the prices to create and install solar cells continues to decrease, more and more homes and businesses are using solar power for their energy requirements. The use of solar power reduces the amount of carbon used for traditional power sources, and can decrease energy costs, therefore, solar power is gaining popularity in many parts of the world.

The solar power is actually gained by installing solar power cells. There are many different types of solar power cells but 4 of them are widely used. Crystalline silicone, ordinary silicon cells, thin film cells, and concentrator cells are commonly used. Crystalline silicone cells are the cells most commonly used in solar power plants. Just like in most semiconductors, the Crystalline silicone cells are also made from two layers, a positive layer and negative layer and when photons from the sun’s light strikes the semiconductors and released electrons, the electric field is created between the two layers. 

Photovoltaic (PV) Energy
Photovoltaic (PV) panels contain hundreds of small silicon cells that collect the sun's energy and convert it into electricity that can be used in the home or offices. With the appropriate power conversion device (inverter), these PV systems can produce alternating current (AC) compatible with any conventional appliances and operate in parallel with and interconnected to the utility grid.

Dynamic Daylighting
Many companies have also come out with smart solar solutions to increase efficient use of resources. One such solution is to control individual sections in a building such as in a floor-to-ceiling window with a hot glare in only one area, thus allowing a work or living space to use daylight rather than artificial lighting, but hold down glare at the same time, making a comfortable work space and still using less energy.

In nutshell, the sun provides an unlimited resource for power around the world and is becoming a positive energy source for people across the world to reduce their carbon footprint and save on energy expenditure.
