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.
How much will my solar panels generate.
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.
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.
How much energy does a solar panel produce.
The power you get from a 100 watt solar panel depends on how much sunlight it receives and on a daily basis the total power is much less than the rated wattage.
The amount of energy your home uses over a certain timeframe say a month is measured in kilowatt hours kwh.
This is a very vague and somewhat difficult question because some appliances are very energy efficient while others are not.
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.
December produces only 122 kwh which is just 17 as much as july.
250wp dc in controlled conditions.
Typically a modern solar panel produces between 250 to 270 watts of peak power e g.
How much power do my electrical appliances need.
March is a lot better at 430 kwh but still only 60 of july s average.
You might think it s a simple math question.
The amount of energy that solar panels can absorb and then produce is measured in kilowatts kw.
On average you can expect a solar panel to generate around 30 000 watts per month.
To put that into perspective a typical household uses about 897 kwh per month.
This becomes crucial when you are looking for portable solar panel systems for your rv.
Solar panels rated at 100 to 200 watts cover about 10 square feet 1 square meter.
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.
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.
5 hours x 290 watts an example wattage of a premium solar panel 1 450 watts hours or roughly 1 5 kilowatt hours kwh.
This is called the nameplate rating and solar panel wattage varies based on the size and efficiency of your panel.
There are plenty of solar calculators and the brand of solar system you choose probably offers one.
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.
With this power capacity you need to then find out how much energy your pv system will be generating and saving more accurately.
