Self-sustaining power is a reality enjoyed by a growing number of households within the United States thanks to a large number of solar electricity systems available to the home or office owner. Legislation, rebates, and buying assistance all make it easier today than in the past to own one of the many types of power sources available with a quick search online or a call to a local provider. Understanding how that unit operates often aids the consumer in deciding whether a purchase is in order or if plans should be placed on hold.
What exactly constitutes solar electricity systems?
A PV cell is the basis of any unit. These specially developed pieces of technology utilize older transition technologies. Pure silicon layers that are thinly cut are combined with other important elements. A cell absorbs the natural sunlight and subsequently produces power.
Photovoltaic modules are a group of cells used to collect the power of the sun. These modules are generally laminated to ensure protection from the elements. Each module contains a number of individual cells that work together to produce the desired results.
A photovoltaic (PV) array is a must for any unit. These are basically all of the individual modules linked together to create a single unit. The array is a group of PV modules connected to create a complete system capable of producing energy.
Generally, solar electricity systems produce DC energy. An inverter is necessary to turn that DC to a more common AC suitable for home and commercial use. A single inverter may connect to an entire array, or a micro-inverter can connect to each module individually. The decision on which one to use depends on the property size and the overall power need.
A mounting system is another necessary component. Rails and racks made of anodized aluminum are generally mounted on a roof or other area ensuring a leak-free and secure placement of the components. Mounts on roofs and the ground are by far the most popular today. However, setup can take place on many suitable surfaces.
Many residential and commercial properties may decide to purchase a battery backup system. Batteries allow the owner to store excess energy for times when the sun is not available so that the home or business owner can still have electricity from solar power. Another method for obtaining extra energy is to use the traditional electric grid in emergencies or as the need arises. Another benefit to being grid tied is that any excess power can be purchased by the local utility company.
There are hybrid solar electricity systems as well. Biogas, diesel, and even wind turbines can be added to PV modules to develop a unit capable of producing large amounts of energy. Additionally, hybrid units mean less dependency on being tied to a grid. By providing alternative sources for the power, the user obtains complete self-sufficiency from the utility company.
While there are many things to keep in mind before purchasing and installing solar electricity systems, the consumer will appreciate the benefits of ownership. Saving money and becoming self-sufficient are two of the most common reasons people turn to the possibilities provided by using alternative sources of power. Every unit is made to best fill the role of the household or business, and finding a professional to assist with developing an ideal unit is a must for any potential consumer.
