How A Commercial Solar System Works

A grid-tied PV system is the essence of simplicity and reliability. Solar modules are wired together to form your solar array. The array is typically mounted on the roof of your facility. The solar modules convert sunlight directly into electrical power.

We carefully select the modules for your installation based on their quality and performance. We will usually select high-efficiency modules, either to maximize available output within limitations of available space, or to reduce mounting hardware and labor costs. We also evaluate the solidity and longevity of the module manufacturer.

We carry SunPower modules, the most efficient commercially available module in the world. We are the only SunPower Premier Dealer in New Mexico. We also carry and install Evergreen and Solarworld, both of which are manufactured in the US, and Sanyo of Japan. .

A mounting approach is selected that best meets your site and facility requirements:

  • flat roofs - either penetrating or ballasted non-penetrating;
  • pitched roofs;
  • solar awning; and
  • ground mounts.

The power runs from your solar array through a DC safety disconnect to an inverter, usually located on an outside building wall. The inverter converts DC (direct current) power generated by the solar array to clean AC (alternating current) power that synchronizes with the voltage of your facility.

The output of your solar system runs through an AC safety disconnect and a solar REC meter that tracks the solar production. The REC meter tracks the power produced by your solar power system before it reaches the breaker panel, meaning that you are credited for your clean power generation whether you use it in your facility or send it into the utility lines. From the REC meter, the output enters a service panel where it then flows to serve your loads.

Any excess energy generated flows into the utility grid, spinning your standard revenue meter backward as a credit for future use. This is called “net metering.” The revenue meter tracks the net amount you pull from the grid. You earn retail rates for the amount of solar production that offsets your consumption.

When your solar system generates less electricity (due to cloudy days, evenings or excess use), your utility company supplies you with the rest. The regular utility meter tracks the net power supplied by the grid. The typical utility-intertied system is batteryless and maintenance free.

If there is a power outage during the day the solar system automatically shuts down, meaning that even if the sun is shining you will not have power during an outage. This is because your PV system feeds into the same breaker panel that is served by utility power. In order to prevent your solar energy from backfeeding into the grid and injuring a utility lineworker, your inverter must instantly shut down. Once utility power is restored, the inverter checks for steady power and reconnects after five minutes.
