have been around for quite a while, but it has only been in the last
decade that they have become as popular as they are. A lot of advances
have been made with photovoltaic power in recent years, and the panels
have become more affordable for people to buy.
While silicon is the main component in a solar cell, pure silicon would not work. Pure silicon has no spare electrons or open spaces for electrons. By “doping” the silicone with specific other materials, spare electrons and spaces for them are created. These electrons moving to find open spaces are what create electrical current.
Solar panels are good at creating energy, but you should buy the nicest panels you can afford. PV panels only convert a small amount of the light that hits them into energy. The nicer panels you get, the more efficient they will be and the longer they will last.
A solar home best in sunny environments, but keep in mind that they will continue to work even on cloudy days. Even on overcast days enough sunlight will hit the panel to keep it working. Solar panels also work in the winter. Since they run off of light, not warmth, they will run as long as light is hitting them. The only thing that will cause them to not produce electricity is if they are covered up.
If you are thinking about getting solar panels for your home or business, there are many places you can get them. You do need to check into the companies that produced them and the one that is distributing them though. Make sure the business has been operating for awhile and that their products have a good record.
Also, unless you have experience with solar panels, you should get a contractor to install them. Look at all the credentials and licensing a Contractor has, and ask for references. Don’t be embarrassed to put them under a microscope. They are going to be installing your expensive solar panels, and they are going to charge you to do it, so you have every right to be picky about which Contractor does the job.
By doing a little searching, you should be able to find just the solar panels and Contractor that you need for your project.
