On-grid solar systems are connected to the local electricity grid, allowing excess electricity to be fed back into the grid and potentially earn credits or payments. Off-grid solar systems, on the other hand, are not connected to the grid and rely on energy storage solutions, such as batteries, to provide electricity when solar production is low or during nighttime.
The main difference between on-grid and off-grid solar systems is how they are connected to the power grid. On-grid solar systems are connected to the local utility grid, allowing excess electricity generated by the solar panels to be fed back into the grid and credited to the homeowner. This means that on-grid systems rely on the grid for power during times when the sun is not shining, such as at night or during cloudy days.
On the other hand, off-grid solar systems are not connected to the power grid and operate independently. These systems typically use batteries to store excess electricity generated during the day for use during periods of low or no sunlight. Off-grid systems are commonly used in remote areas where connecting to the grid is not feasible or cost-effective.
Overall, the distinction lies in the connection to the power grid and the reliance on it for electricity supply.
The main difference between on-grid and off-grid solar systems lies in their connection to the traditional electrical grid. On-grid solar systems are connected to the grid, allowing them to both generate and consume electricity from the grid when needed. They can also feed excess electricity back into the grid, earning credits or compensation through net metering. In contrast, off-grid solar systems are not connected to the grid and operate independently, relying solely on solar energy to generate and store electricity in batteries for use when the sun is not shining. Off-grid systems are typically used in remote areas where grid connection is not available or for those seeking complete energy independence.
