These are used more often in cities, suburbs and industrial areas where access to utility-generated power is available. It allows users to supplement their sun-powered electricity with utility-generated energy if their electrical demand is more than the photovoltaic system supplies.
When the solar system produces more electricity than needed, the excess electricity is sent and sold to the utility company at the retail rate. The utility company then delivers the clean, renewable energy to other customers.

These are grid-tied PV Systems that are integrated in the roof of the home or building and become part of the roof itself.
These are more aesthetically-pleasing and add to the durability and longevity of the roof itself. Thin film technology is used for metal roofs and low-slope or flat roofs. Slate, clay, and composite roofs utilize either thin film technology or tile-integrated solar modules.

These systems consist of solar panels and a battery bank. They are typically used in rural areas and regions where there is no access to the utility grid. They may also be appropriate where the grid is somewhat close to the site, but expensive to bring in. It may also be installed up where the grid is available but where the homeowner has experienced unreliable power in the past or believes that he/she will be subject to power outages in the future.

Grid-tied applications couple the clean, power supplied by solar panels with the assurance that electricity will be present even during power outages.
During the day, the PV system generates electricity as needed and charges batteries. If more power is required, or the batteries begin to run low, the natural gas or propane generator kicks in to recharge the batteries. It automatically shuts off when the batteries are fully charged. During a blackout, power is provided by the batteries and generator.
