A solar panel’s wattage, or power capacity, refers to its energy generation potential, with higher wattage panels able to deliver larger amounts of solar electricity. Solar panel wattage is abbreviated simply with a “W'''' and 1,000W is equal to one kilowatt (kW).
Understanding wattage is essential for determining how much energy a solar panel can produce and, consequently, how much power your devices or appliances can draw from it. For example, a solar panel with a voltage of 20V and an amperage of 5A has a wattage of 100W. This means the panel can produce 100 watts of power under optimal conditions.
The size of solar panels varies, with no definite answer. Their wattages also differ as each system operates on different power levels. To learn more about solar panel sizes and wattage, keep reading.
Since optimal conditions are impossible to achieve at all times, I usually recommend to estimate a 70-80% efficiency when calculating how much solar you need for a specific application. Knowing the wattage helps in selecting the right solar panel for your needs and ensuring it can handle the load of your intended applications.
