Solar power panels are most commonly referred to as PV panels or cells. PV is an abbreviation for photovoltaic – photo meaning light and voltaic meaning electricity. A set of PV panels can be connected together to collect the sunlight and convert it into usable electricity. This is the foundation for solar power.
The initial expanse of purchasing and installing solar power panels is often a large obstacle for homeowners who research converting their homes to solar powered environments. The PV cells are expensive to produce, and because their popularity is still rising, there aren't a lot of manufacturers on the market competing with each other and driving the costs down. However, the need for more energy efficient homes is becoming more and more urgent, resulting in more companies getting into the solar power research and development world. As PV panels become more efficient and less expensive to produce, more models will be available to consumers and the prices will drop to be accessible to an increasing amount of homeowners.
Solar power has been in existence for a lot longer than many people realize. It is not a new technology, though many of the improvements on the solar power front are more modern inventions. While it's been a part of the collective awareness of the world for about a century, there have been a lot of problems related to making homes solar powered until recent years. As solar technology has expanded and solar power panels have become more efficient in their conversion of sunlight to electricity, the possibility of homes running entirely off energy from the sun has drifted into reach.
In an effort to encourage homeowners to build solar powered homes or convert existing homes to solar powered, local and federal governments have introduced rebates and incentives related to the purchase and installation of solar powered systems and products. The amount of solar powered products is quite large. They range from water heaters to lights to ovens to PV panels that power homes, and all of them require solar power panels to work. Anyone interested in converting to a solar powered home should check with their city, state and federal government to learn the requirements needed to get the tax incentives and rebates available for solar power purchase and installation.
One of the greatest advantages to having a solar home is the grid-tie system. A homeowner can choose to connect his or her solar powered home to the local power grid. When connected, the transfer of energy can be two-way. This means that on days that might be a little overcast and not as much power is produced through the PV cells, the home can supplement its electricity needs from the local grid. Conversely, on days where excess power is produced by the PV cells, the home can feed the extra electricity back into the grid. For that, the power company will either buy back the excess power or credit the homeowner's account for future use. Some homeowners choose to have the excess power stored in a battery, rather than selling it back to the power company. This is beneficial for times in storms or other inclement weather when the grid has a blackout. Homes that are solar powered and storing their extra electricity in a battery will be able to continue to run as normal when the power in the rest of the neighborhood is out. Depending on how much electricity is produced by the solar power panels on the home, a combination of both the battery and the electric company's buy-back policy can be used for the home.
