Solar Energy Systems In Arizona

Argent Solar with its headquarters in Goodyear are among the prominent integrators of renewable energy systems in Arizona. The solar energy products of Argent Solar are dependent on the photovoltaic cells and heat engines. The entire range of products includes not only space cooling and heating but also the distillation and disinfection of water to make it potable and solar cooking among others. Argent Solar creates solar installation across Arizona.


The photovoltaic cells or PV or solar cells is the technology employed by Argent Solar in creating solar energy products. These are semiconductor devices that can convert sunlight into DC or direct current electricity. Several groups of these PV cells are wired or networked into arrays. These arrays are used to charge batteries. The DC from these battery banks is converted to AC that is used for powering domestic appliances, lighting and other operations. This AC source can be operated in parallel or interconnected with the utility grid. The PV cell is a thin wafer of N-type silicon placed on top of a thicker layer of the P-type silicon. The P-N junction thus formed creates an electrical field that gets the momentum when sunlight falls on a PV cell. The stream of electrons that results is what is used as electrical energy.
The solar installation once created allows homeowners to receive the entire electrical energy that is created in their homes. The facility of net metering is the accounting of the PV energy system and this allows homeowners to use excess electricity generated to be fed to the utility grid. By this means the meter actually runs backwards in proportion to the amount of surplus energy generated. One can use the credit in kilowatt-hours when required.
