There are worldwide concerns about energy as well as global warming and greenhouse gas emissions, leading many countries to more aggressively pursue alternative and cleaner energy sources. Solar is one of the top choices as an alternative energy source, and much money and research are being invested in further developing this technology.
Currently, less than 0.1 percent of the electricity produced in the United States is fueled by solar power. However, that is rapidly changing, and by 2025 it is projected to rise to at least 10 percent. According to a recent article in Mercurynews.com, the price of solar is dropping, and will eventually be very competitive with other energy sources.
Cost
To determine the cost of a residential solar system, you must take into account the size of the house, the amount of energy needed, and the location of the residence. All of these variables will affect the total price of an installation. This is just a rough estimate, but the average cost of an installed system would be around $36,000 for a 2500 square foot home. This is computing a 4kw system at $9.00 per watt. This figure is just to give you a general idea of the cost, and is by no means perfectly accurate. It also doesn't take into account the various rebates and incentive programs for your individual area. For more on how up-front costs and savings, read Solar and your Pocketbook.
Solar energy is gathered through collectors and can be converted into thermal heat to warm water and buildings; or it can be converted to electricity through either photovoltaic panels or solar power plants.
PV/Thermal
Alternative energy sources have a long way to go before they will become the main energy source within the United States. It is moving in a positive direction with more incentives being offered everyday. Research what programs are available in your area, and then request free estimates from prescreened solar installers to bring solar energy to your home.
