How Much Electricity Does A Solar Panel Produce Per Month

There are plenty of solar calculators and the brand of solar system you choose probably offers one.

How much electricity does a solar panel produce per month. Typically homeowners in the united states use about 900 kwh a month on average. How much power do my electrical appliances need. 250wp dc in controlled conditions. Again though these are just rough estimates.

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. To put that into perspective a typical household uses about 897 kwh per month. December produces only 122 kwh which is just 17 as much as july. If for example the solar panel has a rating of 250 watts of power and the panel received a full hour of direct sunlight and no other factors diminished the power then you would get 250 watt hours of electricity.

This is called the nameplate rating and solar panel wattage varies based on the size and efficiency of your panel. March is a lot better at 430 kwh but still only 60 of july s average. Solar panel systems are measured in terms of kw. Considering 6 peak sun hours per day and 300 watt panels you need 16 to produce 700 kwh each month.

Typically a modern solar panel produces between 250 to 270 watts of peak power e g. An array of this size can produce an average of 350 850 kwh of ac energy 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. So summer is the best overall for me but you might be surprised that there are days even in the middle of winter when you can generate a lot of electricity.

On average this is equivalent to 57 kwh per month and 1 87 kwh per day. 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. This will maximize the watts installed per square foot compensating the area limitation. 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.

On average you can expect a solar panel to generate around 30 000 watts per month. That s enough energy to power some small appliances without too much issue but if you want to cover the energy used by your property s climate control systems or large cooking appliances you ll need more solar panels. As you might expect solar panels are more productive in summer and less productive in winter. A common size solar panel array is usually around 5kw and takes up around 400 square feet of space.

You can use the table of solar power production per kw for each state above to do the same math for your state. If you have limited roof space the best recommendation is installing the most efficient solar panelsavailable.
