How does the solar power system work?

This simple diagram shows how you can have cleaner power at a more affordable price from the sun using the system VuPhongSolar install for your building.

Solar panels (PV module)

The solar panels are made up of photovoltaic (PV) cells, which convert sunlight into direct current (DC) electricity.

Grid-tie Inverter

Since your equipment runs on alternating current (AC) electricity, the inverter converts the DC electricity generated by the solar panels so it can be used as AC electricity.

Electrical Panel / Breaker Box

The AC electricity output from your inverter is then directed to your building’s electrical panel, where it, in turn, powers all that is connected to it, such as lights, appliances, etc.

Utility Meter

The utility meter measures energy you take from and feed to the Utility Grid. You can be assured of a significant decrease in your usage once your solar system is installed and operates. In some cases, your energy usage will actually be reversed when your solar energy system produces excess energy and it goes to the Grid.

Utility Grid

Your building is still connected to the grid, so when the sun goes down at night you’ll still have power. Don’t worry, though, the cost is offset by any excess solar energy you put into the grid during the day via the Net-Metering Program.

24/7 Monitoring System

Our monitoring system continuously tracks your system’s energy production and ensures that your solar energy system is running smoothly.


We’ve engineered a process to make your transition to solar as smooth as possible.
