What are Solar Panels for the Home?

Solar energy is a great renewable resource that is growing in popularity with the average consumer. As energy prices skyrocket and the average income stagnating, if not falling, consumers are looking for a way to reduce their costs of living in any area possible. The rise of renewable energy, and the desire to wean our society off of fossil fuels, makes using solar panels for the home a great alternative for power.

Solar power kits save energy for the homeowner because they allow the homeowner to generate their own electricity to power their home. In some cases, the homeowner can go completely off-grid and even sell additional electricity back to the power company. What a powerful concept to be able to take an expense and turn it into an asset.

What are solar panels?

A solar panel is a packaged interconnected assembly of solar cells that are cased in a housing unit to protect the cells from the weather and from physical damage. These panels generate electricity, which is then used to directly power devices in the home, or charge battery cells to store the power for nighttime use. A solar power kit typically includes solar panels, an inverter and interconnection wiring to connect the panel to the electrical system in the home. For those that want to live off the grid, batteries are included for continuous power during the day and night. The use of infrared solar cells also allows the homeowner to generate electricity at night, thus increasing the efficiency of these cells.

The technology of solar cells continues to advance with time. Currently, the efficiency rate of solar cells range from 5% to 19% depending upon the technology. The reason is that the solar cells (or photo-voltaic cells) only convert a limited range of sunlight frequencies into electricity. The renewable energy industry is experimenting with advanced technologies that will raise the efficiency of these solar cells by a whopping 50%.

A new technology for solar cells, also called thin film or third generation solar cells, is being researched. The plus side of this new generation technology is that it produces solar cells that can operate with a higher efficiency and less cost. These brands are both rigid and flexible thin film modules. The differences between the rigid thin film module and the flexible thin film module are due to differences in the materials that are used to make the modules and differences in the production of the modules.

Solar modules can last anywhere from 10 to 25 years while still operating at 80% of their original capacity. Every year the number of panels sold to consumers continues to grow. In 2007 over 4 million solar units were sold. There are a number of manufacturers that produce solar panels for consumer use, however the average consumer can create their own solar panels using materials from their local hardware store.

Solar panels for the home can provide renewable energy for the consumer. The initial costs can range greatly if the consumer chooses to build their own solar energy kit or have another company install a solar power kit. As the technology improves, the homeowner will have more options available to them to completely power their home with renewable solar power energy.
