How much area can a 27-watt solar integrated device illuminate

These lights will illuminate about 1-5 square feet. . An off-grid solar system's size depends on factors such as your daily energy consumption, local sunlight availability, chosen equipment, the appliances that you're trying to run, and system configuration. Below is a combination of multiple calculators that consider these variables and allow you to. . Our solar irradiance calculator provides estimated W/m² readings, hourly charts, monthly averages, and solar panel optimization tools for solar energy planning. Enter a city name, latitude and longitude, or click the GPS button to use your current position. The area under the solar irradiance curve (W/m2), and the area under the rectangular. . If you are using an DC to AC power inverter, meaning your device is rated in AC amps and 110 V, you will need to convert that number into DC watts before entering it in the field. If you use between 1,000 and 3,000 watts, then a 24V system is best.
