How Much Will My Solar Panels Generate

On average you can expect a solar panel to generate around 30 000 watts per month.

How much will my solar panels generate. This is called the nameplate rating and solar panel wattage varies based on the size and efficiency of your panel. The amount of energy your home uses over a certain timeframe say a month is measured in kilowatt hours kwh. The amount of electricity produced by a solar panel depends on the size of the panel the amount of sunlight the panel gets and the efficiency of the solar cells inside the panel. December produces only 122 kwh which is just 17 as much as july.

If a solar panel is rated to produce say 360 watts and it s about 3 and feet wide by 5 and feet long then each square foot must produce about 20 watts right. For the sake of example if you are getting 5 hours of direct sunlight per day in a sunny state like california you can calculate your solar panel output this way. 5 hours x 290 watts an example wattage of a premium solar panel 1 450 watts hours or roughly 1 5 kilowatt hours kwh. An array of this size can produce an average of 350 850 kwh of ac energy per month.

250wp dc in controlled conditions. This becomes crucial when you are looking for portable solar panel systems for your rv. March is a lot better at 430 kwh but still only 60 of july s average. Solar panels rated at 100 to 200 watts cover about 10 square feet 1 square meter.

A common size solar panel array is usually around 5kw and takes up around 400 square feet of space. For example if a 300 watt 0 3kw solar panel in full sunshine actively generates power for one hour it will have generated 300 watt hours 0 3kwh of electricity. 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. You need to know how many kwhs your home uses to determine the amount of kws your solar panels need to produce to offset your use.

The amount of energy that solar panels can absorb and then produce is measured in kilowatts kw. Compare with your consumption and costs and if it s what you are looking for then divide the power capacity by the nominal stc power of the solar panels somewhere between 350 400wp for your case. You might think it s a simple math question. To put that into perspective a typical household uses about 897 kwh per month.

There are plenty of solar calculators and the brand of solar system you choose probably offers one. This is a very vague and somewhat difficult question because some appliances are very energy efficient while others are not. Therefore it is very possible to generate enough energy to cover 100 of your needs. How much power do my electrical appliances need.

Typically a modern solar panel produces between 250 to 270 watts of peak power e g.
