A watt is defined as one joule of energy transferred per second. This small unit becomes more practical for quantifying the power output of solar panels when expressed in larger multiples, such as kilowatts and megawatts. The watt is the fundamental unit of power used to measure the output of small-scale solar panels and electronic devices.
This means that under standard test conditions, the panel can generate up to 300 watts of electrical power when exposed to full sunlight. The kilowatt is a larger unit of power, equal to one thousand watts. It is commonly used to express the total power output of larger solar installations, such as residential, commercial, and industrial systems.
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.
For instance, a typical residential solar installation might have a total power output of 5 kilowatts (5 kW). This could be achieved with around 16 to 20 solar panels, each rated at 300 watts. The megawatt is an even larger unit of power, equal to one million watts or one thousand kilowatts.
