How Does Solar Energy Work

How Does Solar Energy Work

by Carl Johnson

With energy prices rising higher and higher with no end in sight, these days, the question of how does solar power work is firing up the curiosity of many money-conscious families and individuals. A major concern for people considering going solar is the cost of equipment and installation, but federal and state grants to help defer these costs are becoming increasingly available. Notwithstanding what may seem like a high installation cost, using solar power in the home is a great option for the long term and the ongoing savings will soon off-set the initial outlay.

In both residential and commercial applications the basic concept of how does solar power work is exactly the same with the only difference being the scale of the installation requirements. A factory or warehouse is obviously going to require a larger amount of energy hence a more complex and more expensive installation would need to be in place.

Solar panels are lines with a semiconductor than generates electricity when the suns rays come in contact with it. Solar panels can also be constructed to heat both your water and air coming into the structure through your ventilation system. The electricity generated by the solar panels is then routed to your controller/regulator where the voltage/amperage is adjusted to your system’s needs then routed to your electrical system or storage system.

The essential parts of a solar power system consist of: 1. PV panels which are the solar or photovoltaic panels. 2. Current regulator which is a device for controlling the voltage or amperage of the electricity produced by the solar panel. 3 A storage system which is usually a group of batteries that will reserve for later use the power produced by the solar panels when the sun is up.

Depending on your location or the type of installation, solar panels can vary quite a bit in cost, For instance, if the building is industrial, and is located in a remote area, than you would probably use the typical box shaped panels. When it comes to commercial usage, solar panels can both be installed on the large roof space available on top of businesses and industrial buildings and on the ground in arrays of panels to generate even more solar power.

Solar panels can be mounted in a rooftop setup in addition to ground and pole mounts. The ground and pole mounts offer additional design flexibility especially when your structure is in the shade for part of the day. Solar panels can also be equipped with mechanisms that allow them to follow or “track the sun throughout the day maximizing their exposure to the suns rays. One of the largest drawbacks to solar installation is of course sunset. This is remedied by installing a battery array or storage system, or using supplemental power from the utility company power grid.

If you want a more discrete, dual purpose installation you can even have your structure constructed with solar cells built right into the roofing, awning and window materials. In a residential application using roofing materials with the solar cells built in will give you the same level of protection as an asphalt shingle while functioning as a solar panel, giving you more flexibility in design and reducing the chances your home will look like a space station.
