The cost of an off-grid solar system varies widely based on your energy needs, location, and the types of components you choose. On average, a complete off-grid solar system can range from $20,000 to $100,000. This includes solar panels, batteries, inverters, and installation costs. Smaller setups for minimal power use might cost less, whereas larger homes with higher energy demands could see higher costs. Remember, government rebates and incentives can significantly reduce out-of-pocket expenses.
