On-grid solar systems connect to the utility grid, offering lower costs, no batteries, and net metering to save on bills, but they stop working during power outages. Off-grid systems are independent, using batteries to provide power in remote locations, but are more expensive and require battery maintenance.
- Grid Connection: Always connected to the public electricity network.
- Batteries: No batteries required, making them more cost-effective.
- Power Outages: Do not function during blackouts (due to safety mechanisms).
- Surplus Power: Excess energy is exported to the grid, often earning credits (net metering).
- Best For: Urban/suburban homes with reliable grid power looking to reduce bills
