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.
PV wattage refers to the overall power output that a solar panel can provide in a specific amount of time. It is determined by factors such as voltage, amperage, and number of cells.
For example: A 100-watt panel can produce 100 watts per hour in direct sunlight. A 400-watt panel can generate 400 watts per hour under the same conditions. This doesn’t mean they’ll produce that amount all day, output varies with weather, shade, and panel orientation.
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.
