A Photo-Voltaic (PV) Solar System consists of a group of solar panels, electrical inverters, and safety disconnects connected to your electric meter.

The panels capture the energy from the sunlight, and the inverters transform it into usable electricity. The number of panels and inverters depend on the size of your home and on how much energy you want your system to generate.

By installing a PV Solar Syste, not only will you save on the cost of electricity, but you will help the environment by reducing CO2 emissions and thus reducing global warming.

TNG Electric will design and build a PV system that fits your needs and maximizes the clean production of energy in your own home.

The Sunlight captured by the solar panels is transformed into Direct Current (DC), and then transformed into Alternating Current (AC) by the inverters.

The converted current then passes through safety disconnects, which allow maintenance personnel from the utility company to interrupt the generation of electricity in order to safely work on the grid whenever necessary.

Once the PV Solar System is connected to the main panel, the electricity generated can be used in your home, just as if it came from the utility service electric grid, but without the costly electric bill from the utility company.

If you consume more energy than what you generate, the utility company will provide you with the additional energy you need.

However, if you generate more energy than what you consume, your electric meter will spin backwards and you gain credit with the utility company because you are returning energy to the grid.

There are two main types of Photo Voltaic Solar Systems:

1) Grid tied systems

2) Off grid (Stand alone) systems

Both of these can be either roof mounted or ground mounted, and can have an optional battery backup system.
