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.
However, wattage alone doesn’t tell the full story—actual solar panel output depends on sun exposure, climate, and installation quality. Large rooftops and utility-scale projects use bigger, more powerful commercial solar panels ranging from 500 to 700 watts.
Let''s say you get 26 450-watt solar panels installed on your roof: That gives you a 11,700 watt, or 11.7 kW solar panel system (near the average system size quoted on the EnergySage Marketplace).
To calculate the required solar panel output, multiply the desired output by a buffer (usually 1.2 to 1.5). For example, with a 20% buffer, a 20 watt solar panel would provide 7.2 kW of power.
