Off-Grid & Zero Export Systems Guelph Solar designs and installs custom off-grid systems with battery backup. Off-grid systems are ideal for cottages or remote properties that have no access to power or where power would be too expensive to install. We also install zero export solar panel systems with or without batteries. Zero export systems stay connected to the grid, however, the solar energy produced is consumed in the moment, or stored in a battery. A zero export meter is installed to ensure no power is ever exported to the grid. A zero export system is ideal for properties that consume high amounts of energy during the day. Producing your own solar energy is the cheaper and environmentally friendly option.
