How To Connect Solar To Grid: Complete Installation Guide (2025)
Learn how to safely connect solar panels to the electrical grid with our comprehensive guide covering permits, installation steps, safety requirements, and code compliance.
Connecting solar power to the grid offers a smart, sustainable way to harness renewable energy while maintaining a reliable power supply. Through the use of inverters, net metering, and modern grid technologies, solar energy is being seamlessly integrated into the existing electrical infrastructure.
Most people prefer the series connection from on-grid panels because it significantly increases the voltage received by the grid inverter. To do that, you should connect the first panel's positive terminal to the second panel's negative terminal, which connects to the third panel's positive terminal and continues the process.
Solar inverter installation varies depending on the type of configuration. Thus, to connect the grid inverter to the mains, you must choose if it will connect directly to the battery or not. For instance, the on-grid system inverter is connected directly to the mains, while the off-grid inverter output is first connected to a storage battery.
For an on-grid system, you will not be using batteries. Thus, unlike the off-grid systems, you will connect the inverter directly to the grid. Plug it into the main power switchboard to join the grid, which acts as the input wire. The other wire, which acts as the output wire, connects to the switchboard, which supplies the current.
