How Much Energy Does A Solar Panel Produce Per Month

A common size solar panel array is usually around 5kw and takes up around 400 square feet of space.

How much energy does a solar panel produce per month. Again though these are just rough estimates. Typically homeowners in the united states use about 900 kwh a month on average. Using an example from the table above a 360w panel will produce around 684 kwh per year in a site that offers 1900 kwh kw. If your goal is to produce 1 000 kwh per month then truly you must produce 1 250 kwh per month to allow for loss in output efficiency.

30 panels x 250 watts per panel equals a 7 500 watt system 7 5kw. December produces only 122 kwh which is just 17 as much as july. Given 1kw of panels produces 1642 kwh per year in ca and 1kw of panels takes up 68 42 square feet solar panels installed in california on average produce 23 99 kwh kilowatt hours per square foot per year. On average this is equivalent to 57 kwh per month and 1 87 kwh per day.

On average you can expect a solar panel to generate around 30 000 watts per month. As you might expect solar panels are more productive in summer and less productive in winter. Remember if you are receiving an average of four hours of usable sunshine per day and your solar panel is rated at 250 watts of power then you will need forty panels to reliably generate 1 000 kwh per month. In the example above the solar panel is producing 1 5 kwh per day which ends up being about 45 kwh per month.

As you can see the summer is when my system generates the most electricity with an average total generation of 717 kilowatt hours in the month of july. To put that into perspective a typical household uses about 897 kwh per month. March is a lot better at 430 kwh but still only 60 of july s average. So take 900 kwh and divide by the amount of kwh one solar panel produces over the course of a month 30kwh and you get a 30 panel installation.

An array of this size can produce an average of 350 850 kwh of ac energy per month. You can use the table of solar power production per kw for each state above to do the same math for your state.
