How Much Electricity Does A Solar Panel Generate Per Day

For example a home in cambridge with a 280 watt solar panel that receives 4 hours of sunshine will generate 1 120 watt hours wh or 1 1 kilowatt hours kwh of electricity that day 280 x 4.

How much electricity does a solar panel generate per day.

How much energy does a solar panel produce. That s 1 kwh 1 000 watts in a day per 250 watt panel. You can use the table of solar power production per kw for each state above to do the same math for your state. Typically a modern solar panel produces between 250 to 270 watts of peak power e g.

5 hours x 290 watts an example wattage of a premium solar panel 1 450 watts hours or roughly 1 5 kilowatt hours kwh. 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. An array of this size can produce an average of 350 850 kwh of ac energy per month. If you multiply 1kwh per panel by 30 days in a month you ll find that each 250 watt rated panel will produce about 30 kwh in an average month.

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. A common size solar panel array is usually around 5kw and takes up around 400 square feet of space. To calculate how much electricity a solar panel will produce in a day you simply have to multiply its wattage by the number of sunlight hours. This is called the nameplate rating and solar panel wattage varies based on the size and efficiency of your panel.

However keep in mind that there are many factors at play here so this is really only a rough estimate. On average a normal household will use around 37 kwh per day. Solar panels rated at 100 to 200 watts cover about 10 square feet 1 square meter. Therefore it is very possible to generate enough energy to cover 100 of your needs.

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. So if you have solar panels that each produce 1 kwh of power per day you would need a full 37 solar panels to fully power your home. To put that into perspective a typical household uses about 897 kwh per month.
