Concerned About Power Then Go With Solar Power Panels

Concerned About Power Then Go With Solar Power Panels

by James Johnson

One of the first images that come to mind when the topic of solar energy arises is the solar panel, typically portrayed as an oversized, reflective box parked on a rooftop waiting to catch the suns rays. This is changing rapidly as solar cell technology grows in leaps and bounds.

The heat that is continuously created by the sun can be harnessed for use in heating both water systems and ventilation systems through a solar power panel, generally called a photovoltaic or PV panel. A solar power panel is lined with semi-conductive material, usually silicon-based, which generates electricity whenever light from the sun goes through it. The lining is known as the solar cell. The electricity travels via the semi-conductive material to the electrical system powering your house.

For many years solar power panels were restricted to large, boxy enclosures. Now, the development of solar cells has been opening up new ways of incorporating solar energy production for the home and at work. Solar cells may be integrated now into a large variety of building materials; such technology is generally known as Building Integrated Photovoltaics. Solar cells may now be incorporated into almost anything from roofing to the edges of glass window panes.

Solar cells that are integrated into roofing material will give the same protective qualities as traditional asphalt shingles, while simultaneously gathering energy from the sun. The same technology may also be used for exterior walls, windows, skylights, walkway coverings, awnings, and car ports, and it would appear that, every day, a new means of integrating solar power panels into regular building materials becomes available.

There are a variety of solar power panel assemblies that are mounted off of the building itself. The two most common are ground mounted or pole mounted fixtures. These features are valuable as they allow for optimal placement of the solar panels where they would receive the greatest exposure to the sun, thus allowing for greater flexibility in both building design and solar power system design. Although solar power panels will generate some power with indirect exposure to the suns rays, you will only generate the most efficient amount of solar power with direct exposure of the solar panel to full sunlight.

Ground-mounted structures are typically mounted to metal frames that are anchored into the ground via traditional construction methods. These frames may be built with motorized mounts for solar power panels, which let them track or follow the course of the sun during the daylight hours.

Pole mounted structures which are mounted either to the top or side of a metal pole can be constructed to allow the solar panels to track the suns path to receive the maximum amount of solar exposure throughout the day.
