Grid-Tied and Off-Grid Solar



Battery Systems

    Grid-Tied systems refer to those systems that are connected to both the utility’s electrical grid and to your personal PV system.

    These systems allow electricity to flow back out into the grid when not being used by your home.

    During the evenings and nights when electricity is not being produced, the grid provides the electricity to power the house.

    This give and take will results in 0 net electricity consumption when a system is sized properly, though the utility will still have connection fees and other charges.

    Off-Grid systems refer to those solar installations that are not connected to the community electrical grid. These can include mobile offices, RVs, Houseboats, remote structures, etc.

    During peak times of energy production, the unused power is stored for later use in a battery system (if installed).

    When there is no sunlight the battery system powers the connected electrical appliances and lights.

    Call APG today to find out how we can help with your off-grid needs.  

    Batteries are utilized primarily in off-grid solar installations, though there is much talk about residential storage today. The solar panels first power everything connected to them, then the extra power charges the batteries for use when there is no sunlight.

    Back-up battery systems can be installed with a grid-tied system if there is concern about the utility grid going down for long periods of time, but this is very uncommon in central California.

    For backup short term electricity needs we often recommend a generator before relying on batteries.
