Solar power as a function of time in kwh or wh that your solar panel can produce taking into account its rated power and solar energy available at your place.
Max solar panel output per square foot.
As of march 5 2019 the highest wattage solar panel available is the sunpower 415 watt residential solar panel.
That s about 500 550 kilowatt hours of energy per year from each panel on your roof.
4 how does that compare to your annual energy usage.
The first is to look at the peak possible instantaneous solar power production per square foot for a particular solar panel.
Multiply 5 hours of sunlight x 290 watts from a solar panel 1 450 watts or roughly 1 5 kilowatt hours per day.
But at 20 watts per square foot a system rated to produce 2 kilowatts would cover roughly 150 square feet while a 3kw system would take up about 225 square feet.
Another way to say this is at its maximum a 345 watt solar panel puts out a maximum of about 20 watts per square foot 345 divided by 17 3 equals about 20.
Of my 2200 square foot roof half of which is usable for solar 1100 square feet would generate a max output of 13 200 watts 1800 less than if i simply put up the highest efficiency and cost effective pvc panels on the market.
The solar panel with the highest watt is the sunpower e series a commercial solar panel line.
For a 300 watt solar panel with dimensions 64 inches x 39 inches 1 61 meters squared or 17 31 square feet the peak instantaneous electricity production per square foot at stc is 14 58 watts per square foot.
The standard solar panel has an input rate of around 1000 watts per square meter however on the solar panels available at present you will only gain roughly 15 20 efficiency at best.
Domestic solar panel systems typically have a capacity of between 1 kw and 4 kw.
60 cell solar panels are typically 5 4 feet tall by about 3 25 feet wide and have a power output in standard test conditions of between 270 watts to 300 watts depending on the exact efficiency of the cells in them.
Solar panels usually range in wattage output from around 250 watts to 400 watts but some panels exceed the 400 watt mark.
Therefore if your solar panel was 1 square meter in size then it would likely only produce around 150 200w in good sunlight 4 3k views view 3 upvoters.
The top panel in the e series comes out at a whopping 435 watts.
Plus i can have them angled towards the sun for better output.
A 4 kw solar panel system on an average sized house in yorkshire can produce around 2 850 kwh of electricity in a year in ideal conditions.
