Under optimal conditions, a 28W solar panel can produce approximately 28 watts of power per hour. Given around 5 to 6 hours of effective sunlight, the daily output could range from 0. The biggest the rated wattage of a solar panel, the more kWh. . Solar panels degrade slowly, losing about 0. 5% output per year, and often last 25–30 years or more. This is its *peak* rating, achieved only under perfect lab conditions.
