Watt Hours Produced By The Average Solar Panel

Let s say on a good day you average 5 hours of direct sunlight.

Watt hours produced by the average solar panel.

5 hours of sunlight per day on average. 200 watt solar panels. For instance if the surface area is 1 500 square meters and the rating of the panel is 250 watts you would divide 250 by 1 500 and then multiply by 100 to find the percentage for this example the solar panel in question would have an efficiency rating of 16 67 250 1500 x 100 16 67. For example if the.

No shading from trees. Calculate the current produced by the solar panel when it is generating its maximum power. This brief equation shows how sunlight and a solar panel s specifications turn into the amount of power generated. You need to divide the number of watts at which the panel is rated by the total surface area of the panel.

Average watt hours wh produced by a 100 watt panel per day in each state this map shows watt hours per 100 watts of solar panel system capacity. According to the u s. The solar panel with the highest watt is the sunpower e series a commercial solar panel line. Average kilo watt hour production examples for solar panel systems.

Solar panels usually range in wattage output from around 250 watts to 400 watts but some panels exceed the 400 watt mark. 10 solar panel system. This could power a 50 watt laptop computer for 10 hours or a 15 watt compact fluorescent lamp for over 33 hours. The top panel in the e series comes out at a whopping 435 watts.

The first is to look at the peak possible instantaneous solar power production per square foot for a particular solar panel. For a 300 watt solar panel with dimensions 64 inches x 39 inches 1 61 meters squared or 17 31 square feet the peak instantaneous electricity production per square foot at stc is 14 58 watts per square foot. Based on the efficiency of the average solar panel you can expect to convert between 15 and 20 of sunshine into electricity. Multiply 5 hours of sunlight x 290 watts from a solar panel 1 450 watts or roughly 1 5 kilowatt hours per day.

It also assumes a perfect installation facing due south at an optimal tilt angle and unshaded between 9am and 3pm. For example a 50 watt light bulb left on for one hour would be 50 watt hours and 20 50 watt light bulbs running for one hour would be 1 kilowatt hour kwh. If your area gets an average of 5 hours of direct sunlight then your 100 watt solar panel should produce 500 watts of power per day. Calculate the current in amps by dividing power in watts by the voltage in volts.

A 360 watt panel will tend to produce around 20 more energy than a 300 watt panel even if they don t operate at their rated wattage in actual projects.
