Solar Panels in Tucson
If you are wondering why you should install Tucson solar panels, Southwestern Solar can help you understand the various benefits. Since 1968, our parent company has been helping people in the region harness the sun’s energy, and we can help you do the same thing.
We use photovoltaic cells, which capture the energy of the sun’s light by forcing movement of electrons between semi-conductors. The electrons must flow through wires and circuits to return to their normal place, and this creates electricity. While the way this works is highly scientific and technical, the basic point is that homeowners can harness the sun’s energy to make usable electricity for their homes with a simple system.
What makes this system so efficient is the fact that it contains no moving parts. Without an engine or other moving system, your unit cannot wear out. Once it is installed, it will continue creating electricity for you until you take it down.
If you are interested in learning more about the benefits of Tucson solar panels, call Southwestern Solar today. We will set up a free, no-obligation assessment. Our trained installers will help you understand how the system works, and show you just how much you can stand to save on your energy bills. Our customers are homeowners just like you who have chosen to make use of Arizona’s often neglected sunshine to power their homes.
The first practical application of photovoltaic technology was to power orbiting satellites, followed by off-grid stand alone solar power systems. Today, the majority of photovoltaic modules are used for grid-tied power generation. Grid-tied connected solar is made possible by a practice called net metering.
Net metering is a simple concept; power created from your solar system is connected to the electric grid and credited in real time. Any excess power created by the solar system that you are not using, at that moment, is fed back into the power grid. As this excess power is “back-fed”, your meter operates in reverse. Literally your meter spins backward! The power grid is managed by your local utility company and includes everyone connected to it. Any power you don’t use is credited back to you and reduces your bill. Net metering simplifies the solar system design into four major components:
- Solar Modules – The solar modules or solar panels as they are commonly known are the power generating device of the system. Whenever light is present (even on cloudy days) the panels will generate electricity.
- Racking System – This is the permanent support system attached to the structure of a building or to the ground on which the solar panels are fastened.
- Wiring System – This is the electrical set of wiring and disconnect switches between the solar modules and the meter.
- Solar Inverter – This is a power conditioning device which changes the current coming from the solar modules in the form of Direct Current (DC Power) into Alternating Current (AC Power). The inverter is responsible for making the solar system power match synchronously the power coming from the utility.
