Solar Panels: Sustainable Energy for the Future
It seems that solar panels were considered more science fiction than fact only a few short years ago. However, the 21st century has seen a massive proliferation in the use of this photovoltaic energy to help power our homes, businesses and even our vehicles. The impact of these highly efficient and completely renewable systems cannot be overstated and a few recent news articles clearly demonstrate their importance to our modern society.
How Does Solar Technology Work?
Simply stated, a solar photovoltaic panel converts sunlight into electricity utilizing the motion of fast-moving electrons within the panels themselves. A current is created which can then be used to help run machines, heat water and perform various other tasks around the home or office. These "packets" of light are completely renewable and represent a pure form of green technology.
Panels can be mounted in various locations throughout the home or business, but most normally they are placed on a roof or other area which will be exposed to appreciable amounts of sunlight. Skilled technicians will install these devices at the optimal angle to capture the greatest amount of inbound light. They have now become lightweight, unobtrusive and relatively cheap, thus making them ideal for many homeowners.
So, let us briefly review why such technology has become so popular:
- These panels are low-cost solutions to household and business needs.
- A solar cell panel is easy to install.
- These innovations are environmentally friendly.
- Increased efficiency has made photovoltaic systems extremely powerful.
Advice When Installing Solar Panels
Although some consider this technology a do-it-yourself project, it is advised to hire a trained professional that can help make certain the installation goes as planned and the panels are placed in the correct configuration. Naturally, companies that have a solid reputation and provide services that are reinforced by a warranty are the most preferable. Also, it is an excellent idea to ask the provider for a detailed cost analysis of the money expected to be saved when using the benefits of a photovoltaic solar panel.
During an initial consultation, a specialist will determine various factors. He will inquire what the system will be used for. Common uses include heating and electrical supplies to everyday appliances. The amount of space that these panels will occupy will be carefully studied as well as the amount of regular sunlight a residence or business receives. This will help decide whether the roof may offer the most light or perhaps a standalone structure in a yard may be better suited.
There are even different types of cells that may be used; each providing certain advantages and drawbacks. Above all, it is important to note that a solar cell panel is much less bulky and heavy than only a few short years ago. Therefore, the number of locations where they can be used has expanded dramatically.
Once again, let us look at some of the main factors to determine when choosing to install a photovoltaic solar panel:
- Choose a company with a robust reputation and a service guaranteed by a warranty.
- Ask for a cost-benefit analysis.
- Determine various factors such as location, the amount of sunlight received and the type of cell.
