Why you may want to install a solar electric system for your home or business

 

More and more Ben's Green customers are showing interest in solar electric systems for their homes and businesses. Why?

  • Solar electric systems are safe, reliable, pollution free, and use a renewable source of energy—the sun. Most systems have no moving parts and are increasingly easy to install.
  • The option of net metering, or interconnecting a customer generating system to the utility grid, makes solar electric systems more economically viable.

If you are interested in making a long-term investment to protect yourself from rising energy costs and want to reduce your personal environmental impact, now may be the time to learn more about installing a solar electric system for your home or business.

 
A PV System includes:
  1. PV Array—Multiple PV panels installed together are called a PV array. Mounting arrays to rooftops is most common, yet they can also be located on a pole, a ground mounted rack, parking area shade covers, window awnings, etc. The PV array produces Direct Current (DC) power.
  2. DC Disconnect—The DC Disconnect is a safety device that, when manually opened, stops power running from the array to the rest of the system. The DC disconnect is used during system installation and anytime your contractor needs to work on the system. 
  3. DC/AC Inverter—The PV array produces DC electricity, however, we use Alternating Current (AC) electricity in our buildings and power grid. The Inverter converts the DC power to AC power.
  4. AC Disconnect—The AC Disconnect is another safety device and is often incorporated into the Inverter.
  5. Production Meter—The Production Meter measures the energy output (in kilowatt-hours, kWh) from your system and is used to record the amount of electricity generated.
  6. Building Breaker Box and Standard Utility Meter—Also called your building’s circuit panel or electrical service panel, the Breaker Box is where the power from the PV System enters the building. If the building is using electricity, the PV-produced electricity will be used first. If the building needs more electricity than the PV System is producing, utility grid power is automatically pulled into the building. When the PV System produces more electricity than is needed, the excess flows back out to the utility, spinning your utility billing meter backwards in the process. You earn credit for the excess power produced and can use that credit when the system is not producing energy. This process is referred to as “net metering.”
