See How Solar Power For Homes Can Work For You
Fossil fuels will run out at some point in time. The government is working to explore other forms of energy including the large scale uses of solar energy. Solar energy is a renewable form of energy that will benefit the entire earth when our technology and available resources catch up. For now, homeowners are employing solar energy on a smaller scale.
What is Solar Energy
Solar energy is power from the sun. The sun is a giant star millions of light years away from earth that provides light and heat for the third rock we call home. Each day, our planet is bombarded with solar radiation, some good and some bad. A portion of the energy is reflected back into the atmosphere. Of what gets through, some is harmful UV radiation that is filtered in part by our ozone layer.

But, the majority of what gets through, is useable for conversion into other forms of energy that we can use. And, this energy will hit the planet as long as the sun exists. So, for us, it is a fairly renewable energy source.
Solar Panels
The solar energy that hits the earth has to be converted into electricity. The process takes place in those solar panels you see atop homes, in yards, and on other structures requiring electricity. The solar panels are made up of smaller components called photovoltaic cells. These cells collect and convert the sun’s energy into 
electricity.
Using a semi-conducting medium like silicon for the solar cells, the sun’s radiation hits the silicon cells and knocks electrons loose. These electrons are free to move inside the solar cell and are then turned into electricity using a solar home system. The solar panels contain about 40 cells per panel. The number of panels needed to power a home on a daily basis depends on the amount of electricity you use.
Energy Consumption
Many of us can make changes in our consumption levels and installing a solar power system is the perfect time to start. Solar power systems can run with or without a battery backup. The battery is used to store excess electricity until it is needed. This is important if you don’t receive any power from an energy grid. Within an energy grid, stored solar power can reduce the amount of electricity you draw from the grid.
The Cost of a Solar Power System
The cost of a solar power system depends on a few things:
• Size of home
• Size of solar power system
• Homemade versus prefabricated
A prefabricated system will cost a lot more than building your own. But if you don’t have the time or the knowledge for such a job, a good system will count as an investment. As long as you take care of it, it will provide you with energy for a long, long time.
