Solar Products

Solar Electricity is also known as Photovoltaics or “PV” for short. PV systems can be mounted on a roof or on the ground. They provide electricity for buildings such as your home or office; they can also provide electricity for factories or utilities.


How it Works:

  • Light from the sun strikes the PV module (also known as the PV panel) and makes DC electricity. DC means Direct Current. It is the same kind of electricity that batteries produce.
  • Your home runs off AC electricity, or Alternating Current. To convert the DC electricity from the panels to the AC electricity for your home, we install an inverter (see the diagram). The inverter is usually installed in your garage or basement. We try to install your inverter as close as possible to your circuit breaker panel.
  • The inverter will be wired to a new breaker in your panel which will feed electricity into your home, rather than pull it from the grid.
  • During the day, this will cause your utility to meter to slow down or spin backwards. Now the solar panels are supplying your house with electricity, not the utility grid.
  • You will only be charged for what you pulled from the grid at night if it is more than what you produced during the day. We like to size systems that provide close to 100% of your electric use so that your utility bill will be negligible.
