The price of a single solar module, commonly referred to as a solar panel, depends on its capacity, technology (e.g., monocrystalline, polycrystalline), and brand. On average, prices can range from $0.70 to $1.50 per watt. Therefore, a standard 300-watt solar panel might cost between $210 and $450. Prices are continuously evolving, so it's beneficial to research current rates and seek bulk purchase discounts if applicable.
