A 500 watt solar panel is a photovoltaic module engineered to produce up to 500 watts of direct current (DC) power under standard test conditions (STC), which include 1,000 W/m² sunlight
Learn More
Solar panels receive their ratings under specific testing conditions known as "Standard Testing Conditions" or "STCs". These conditions serve as the industry standard for evaluating solar
