The price of a single solar panel can vary widely based on several factors, including its size, efficiency, type, and brand. As of 2023, the price for a standard 300-watt solar panel typically ranges from $200 to $400. High-efficiency models, which can produce more electricity in smaller spaces, often come at a premium, costing between $400 and $600 per panel. On the other hand, budget options are available, with some manufacturers offering lower-priced panels, but often with less efficiency and durability.
