An off-grid solar system is a self-contained energy system that generates electricity, stores that power in solar batteries, and runs independently from the power grid. It is not connected to the utility grid, and the excess energy produced by the solar panels is stored in batteries for later use. The main components of an off-grid solar system include solar panels, batteries, charge controller, and inverter.

The key differences between off-grid and on-grid (grid-tied) solar systems are as follows:

• Electricity Access: With an off-grid solar system, you’re completely reliant on the sun and energy stored in batteries to power your home or business. If you do not have batteries or a means to store your energy, you will have less or no electricity when it’s cloudy, and you will not have electricity at night. With an on-grid solar system, you are connected to the utility grid and can draw electricity from it when your solar panels are not producing enough energy.

• Equipment Needed: Off-grid solar systems require batteries to store excess energy, while on-grid systems do not. On-grid systems are connected to the utility grid and can sell excess energy back to the electric company through a process called net metering.

• Cost: The cost of an off-grid solar system has a wide range because there are a variety of sizes, applications, and components that impact the price. On the other hand, grid-tied systems are significantly cheaper because the owners do not need to buy expensive batteries to add to the system.

Off-grid solar systems are ideal for remote locations where it is difficult or expensive to connect to the utility grid. They offer energy independence and savings amid rising electricity costs. The cost of an off-grid solar system varies depending on the size, application, and components, but it can range from $30,000 to $60,000.
