But it's rated at 300 Watts, shouldn't it produce 300 Watts of power? Well, you might already know this, but the answer is this: The amount of power that a solar panel produces. A solar panel's wattage rating (for example, 300 W, 400 W, or 550 W) indicates its maximum power output under ideal laboratory conditions called “Standard Test Conditions” (STC). This represents the instantaneous power a panel can deliver when the sunlight intensity is 1000 W/m² and the cell. A 300W solar panel that absorbs 8 hours of sunlight per day will generate nearly 2. Hence, if we multiply this by 365 days annually, we acquire a solar output of roughly 900 kWh per year.
