Residential solar energy

As natural resources continue to disappear and the impact of energy production on the environment becomes clearer, environmental and health concerns increase. Current energy production methods are wasteful and can result in pollution of the air, soil, and water. Dangerous gases can damage the ozone layer protecting the earth from damage. Traditional energy production methods also result in a lot of waste, making them less than cost-effective. Solar energy is a great alternative to traditional methods of energy production and has a wide variety of applications. Understanding how solar energy works and how it can be used in homes and businesses will help to increase awareness of and appreciation for this clean energy production method.
Unlike more traditional methods of energy production, solar energy does not involve the use of heavy equipment that can cause pollution and cause health problems. Instead, solar energy can be created using solar cells (also called solar panels) that harness the energy of the sun to create energy for commercial and residential use. In the production of solar energy, units of energy called photons are given off by the sun. When these photons hit the materials contained in a solar cell or solar panel, electrons are released and then absorbed back into the materials. The constant release of electrons followed by their reabsorption is what creates energy.
To gain a better understanding of this process, it’s helpful to know about the materials contained in solar cells and how they can create a charge. Solar cells contain silicon, which is a very stable element. Silicon has four electrons in its outer shell, but it wants to fill the shell with eight electrons. What happens is, one silicon atom will bond with another silicon atom to fill its outer shell with electrons. This creates a strong, stable bond. In order to create a charge, the number of electrons must be changed. A negative charge is created by adding phosphorus to the silicon, while adding boron to the materials will result in a positive charge being generated. This is the basic process behind the creation of solar energy.
Solar energy has many applications for homes and businesses. One of the most common applications is in architecture and neighborhood planning. As society has tried to move away from traditional energy production and toward solar energy production, architects and designers have been designing homes that are to be used with solar energy. When designing these homes, architects plan heating and cooling systems, lighting, and other systems around the use of solar energy. The fields of agriculture and horticulture have been making use of solar energy for years. Greenhouses are used in horticulture to convert solar energy into heat that can be used to protect plants from harsh environmental factors and encourage growth and development. Solar energy is also used for residential heating and power generation systems, such as hot water heaters. Instead of using electricity to heat water, solar energy can be generated using a solar thermal collector. This results in the ability to heat water without using inefficient electrical equipment.
There are many reasons to use solar energy to replace more costly and inefficient energy production methods. One main reason to use solar energy is because it is a clean form of energy. When other forms of energy are produced, there are usually waste products that can contribute to environmental pollution or increased energy costs. When solar energy is used, there are no harmful chemicals involved and no hazardous waste products to dispose of properly. This means that the environment can be protected from further damage. Solar energy is also ideal for use in homes where people have allergies or other medical conditions. The cleaner energy production means that there are fewer irritants in the air that would aggravate allergies and other symptoms. These benefits of using solar energy over traditional energy production methods can benefit everyone.
