Only the tiniest fraction of the Earth, less than a thousandth of a percent, would need to be covered with solar panels in order to power it completely. Germany leads the way in capturing solar energy, but anyone could benefit with a nearly 200% return on investment. Plus, each kW of power that your solar panels generate means that 150 pounds of coal does not have to be mined. To find the right solar panel systems, you can do some preliminary research to find the solution that best fits your needs. As you begin to search for solar panel mounting systems and panels, you may want to start by soliciting input from friends or neighbors, especially if they have recently undertaken a new solar panel initiative. Alternatively you can research the different options on third party review sites. The advantage to using reviews from these sites or forums is that you are getting first hand feedback from other customers that can best address the pros and cons from their perspective. As you begin to get feedback and research, you will want to start looking at some of the specifics of the installation. For example, what components are included in each system, such as: 1. Solar panels, and what dimensions 2. Solar tracker kits or complete solar panel tracking systems 3. Solar panel roof mounts or solar panel brackets Taking all of the components into account, you should also be able to spot trends in terms of owner satisfaction, ease of installation, and return on investment. Ideally this will also allow you see which system is best suited for your application. Since homeowners choose different mounting locations and panel dimensions, you will have to speak with the various companies to understand your options. They can help you put together a comprehensive system, whether it is an ambitious design with solar panel tracking systems or just a few panels to help offset some energy costs. Finally, you may want to look at tax and energy credits that are available to end users. Your diligence in research will enable you to both decrease energy costs and to positively impact other sources of energy. Regardless of which solution you select, you can be assured that you are selecting a green solution.
