Average Solar Panel Electricity Output:

In order to determine the output of a given solar panel, or solar panel system, any scientist or math wizard would need to know a few different variables.  To keep this equation relatively simple, we will assume that some very strange factors like energy loss is the industry average and nothing more or less than that.

Here are the variables we need to determine solar panel electricity output:

1. Solar panel wattage or panel size
2. Average sunlight hours in the solar panel’s location
3. Tilt or angle of the panel towards the sun (is the panel a fixed panel, or does it rotate throughout the day)

Example 1:

175 watt solar panel

5 average sunlight hours per day per year

175 watts DC * 5 hours = 875 watt hours per day per year in Direct Current

After expected energy loss = 743 watt hours in Alternating Current or AC

.743 kwh per day average solar panel kilo watt hour output

Example 2:

180 watt solar panel

6 average sunlight hours per day per year

180 watts DC * 6 hours = 1,080 watt hours per day per year in Direct Current

After expected energy loss = 918 watt hours in Alternating Current or AC

1.08 kwh per day average solar panel kilo watt hour output

Example 3:

200 watt solar panel

5.25  average sunlight hours per day per year

200 watts DC * 5.25 hours = 1,050 watt hours per day per year in Direct Current

After expected energy loss = 892 watt hours in Alternating Current or AC

.892 kwh per day average solar panel kilo watt hour output

Example 4:

170 watt solar panel

7 average sunlight hours per day per year

170 watts DC * 7 hours = 1,190 watt hours per day per year in Direct Current

After expected energy loss = 1.011 watt hours in Alternating Current or AC

1.011 kwh per day average solar panel kilo watt hour output

Example 5:

100 watt solar panel

5 average sunlight hours per day per year

100 watts DC * 5 hours = 500 watt hours per day per year in Direct Current

After expected energy loss = 425 watt hours in Alternating Current or AC

.425 kwh per day average solar panel kilo watt hour output
