Solar panel watts per square meter (W/m) measures the power output of a solar panel based on its size. Compare solar panels to see which generates most electricity per square meter. A higher W/m value means a solar panel produces more power from a given area. This can help you determine how many solar panels you need for your energy needs.
Solar panels are rated by their peak DC power under ideal test conditions. Homeowners use AC electricity, so inverters convert DC to AC with a small efficiency loss (around 3–5%). Over the past decade, panel wattage has climbed steadily. Here’s a snapshot of what’s common now: 250–300 W: Older or budget-friendly modules.
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.
Before sizing a solar array, it helps to know a few key terms: Watt (W): measures power. A solar panel rated at 300 W can deliver that amount under optimal sunlight. Kilowatt-hour (kWh): a unit of energy equal to 1,000 watts for one hour. For instance, a 300 W panel producing peak power for four hours generates 1.2 kWh that day.
