Off-grid solar refers to solar energy systems that are not connected to the electricity grid. Instead, they rely on solar panels to generate electricity, which is then stored in batteries for use when sunlight isn't available. This setup is ideal for remote areas where grid connection is impractical or too expensive. Off-grid systems typically require careful planning to ensure the battery capacity and solar panel size meet your energy needs. If you're considering going off-grid, it's a good idea to consult a licensed solar installer who can assess your situation and provide tailored advice.
