The amount of energy produced by solar panels varies depending on several factors. One of the most important factors is the wattage of the solar panels. The higher the wattage rating of a panel, the more energy it can produce. For instance, a 300W panel will produce more energy than a 200W panel. Another important factor is the efficiency of the solar panels. Higher efficiency panels can convert more sunlight into electricity than lower efficiency panels. For example, a panel with an efficiency rating of 20% will produce more energy than a panel with an efficiency rating of 15%. The amount of energy produced by solar panels depends on several factors, including the panel's wattage, efficiency, location, and the amount of sunlight it receives. A standard 60-cell solar panel with a wattage rating of 300 watts peak (Wp) can produce about 1,200 kilowatt-hours (kWh) of energy per year in areas with ample sunlight, such as California or Arizona. However, in areas with less sunlight, such as the Northeast, the same panel may produce only around 900 kWh per year. The location of the solar panels is also crucial. Areas with higher levels of sunlight, such as the Southwest region of the United States, will produce more energy than areas with lower levels of sunlight, such as the Pacific Northwest. Finally, the amount of energy produced by a solar panel system depends on the amount of sunlight the panels receive. A system that is shaded for a significant portion of the day will produce less energy than a system that receives direct sunlight for most of the day.
