The experts at the U.S. Department of Energy promote the use of solar energy power as a way to reduce dependency on fossil fuels. This can have a positive effect on the environment while reducing energy costs for businesses and homeowners who implement these systems. Here are some of the most important facts about solar energy systems in the Savannah, Georgia, area.

The Basics of Solar Energy Power

According to the Department of Energy, the sunlight that hits the surface of the earth in 90 minutes is capable of powering global energy consumption for an entire year. By harnessing this power, individuals and businesses can achieve greater energy efficiency and can reduce the cost of powering their homes and buildings. Solar power offers a number of important benefits for families and businesses, including the following:

  • Improved energy efficiency and reduced dependence on fossil fuels
  • Lower costs for powering, heating and cooling buildings in our area
  • Sustainable energy that requires minimal maintenance
  • Reduced impact on the environment and a smaller carbon footprint
  • Increased property values for homes and office buildings equipped with these systems

Understanding how these systems work can help you determine if solar power is the right choice for you and your property. Most solar energy systems can be classified into three primary categories:

  • Photovoltaic systems use panels to absorb photons from sunlight. This creates an electrical current that can be captured and used to power household systems or to provide electricity for businesses.
  • Concentrating solar power is used by large-scale energy production facilities and is not generally available for purchase and installation by private companies or property owners.
  • According to the U.S. Energy Information Administration, thermal systems are ideally suited to heat water for residences and businesses. They can also be used to supplement or replace heating systems in our area.

Photovoltaic systems are most commonly available for commercial and residential installation. These systems can be designed to suit your specifications and can add real value to your Savannah property.

How Photovoltaic Solar Panels Work

Photovoltaic solar panels are made up of many small photovoltaic cells. These cells are composed of two layers of semiconducting materials that interact with photons to free electrons from their atoms. Silicon is the most commonly used material for these cells. The top layer of silicon is usually infused with phosphorus to create a negative charge. The bottom layer is seeded with boron to create a positive charge, resulting in a flow of electricity between the two layers of the photovoltaic cell. The electricity generated by photovoltaic panels is collected by conductive plates that usually run along the sides of the individual photovoltaic cells. These plates transmit electricity to wires that can conduct it to storage cells or to an inverter where it can be converted from direct current to alternating current. This is necessary to allow solar arrays to power household appliances and other systems inside Savannah homes and businesses.

Planning Your Solar Power Installation

Savannah typically averages more than 200 sunny days each year. Installing solar panels can help you put that sunlight to use in your home. Solar panels can be installed on the roof or in other areas that get plenty of sunshine. Before beginning your project, your solar technicians will evaluate the proper placement of your panels. They will also provide you with an overview of your home’s current energy efficiency, the amount of electricity your home requires and the potential energy production possible with your new system. Solar panel systems can be used to power compatible HVAC systems and other electric appliances in your home. Choosing an HVAC company with real experience in solar installations can ensure the most practical and cost-effective results for your Savannah home or business.
