Wattage refers to the amount of electrical power a solar panel can produce under standard test conditions (STC), which simulate a bright sunny day with optimal solar irradiance (1,000 W/m²), a cell temperature of 25°C, and clean panels. In simpler terms, a panel’s wattage rating tells you its maximum power output under ideal conditions.
The Wattage rating of a solar panel is the most fundamental rating, representing the maximum power output of the solar panel under ideal conditions. You’ll often see it referred to as “Rated Power”, “Maximum Power”, or “Pmax”, and it’s measured in watts or kilowatts peak (kWp).
For instance, a -5%/+5% power tolerance indicates that the actual power output may vary by up to 5% of the rated power. With this tolerance, a 400 W panel may in fact be anywhere from 380 W to 420 W. On the other hand, a -5/+5 W power tolerance means the panel output may be out by 5 watts on either side of its rated power.
In the example you see above, there’s an “Output Tolerance” rating of -3% to 3%. This means that, under ideal conditions, the 100W solar panel could generate between 97 and 103 Watts of power.
