Technical FAQs 4

What is the difference between on-grid and off-grid solar?

On-grid solar systems are connected to the utility grid, allowing constant electricity access and net metering benefits. Off-grid solar systems offer complete energy independence, relying on solar panels and batteries for power generation and storage.

Should I Choose an on-grid or off-GRI Solar System?

Your long-term goals play a crucial role in deciding between an on-grid or off-grid solar system. Both systems offer unique benefits, but their alignment with your priorities will determine the best choice for you. If energy independence is your priority, an off-grid solar system is the ideal choice.

What is an off-grid Solar System?

Off-grid solar systems: Off grid solar systems work independently from the utility grid. They solely rely on the power generated by solar panels, which is typically stored in batteries for continuous supply. Off grid systems are designed for those who desire complete energy independence and wish to disconnect from their utility providers.

What is a solar grid system?

As the name implies, a solar grid system is one that is wired into the primary electrical grid. They are the most basic, affordable, and widely used kind of solar system because they don’t require an additional solar battery to function. 2) How Does The Cost Of Installation And Maintenance Vary Between On-Grid And Off-Grid Solar Systems?
