One of the biggest misconceptions people have when sizing up a solar system is to think that a 5kw solar system will produce 5kw of power at any one time.
How much power does a 5kw solar system produce per day.
How much does an average 6kw solar system cost.
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 optimally tilted 85 efficient north facing 5kw solar system in sydney for example would produce about 3 5 psh x 5kw x 85 15kwh of power on a day in the peak of winter whereas in the summer output from the same 5kw solar system would be around 6 2 psh x 5kw x 85 26kwh.
How much energy does a solar panel produce.
Therefore to figure out how much power the panel produces in a day simply multiply the 250 watts by 4 hours which comes to 1000 watts per day.
The reality is a 5kw system will output a bit less than that with peak output on a good day being somewhere between 4kw and 4 7kw during the middle of the day and a less in the.
Figures are only to be taken as rough estimates.
So for example you will need between 15 and 22 solar panels for a 6kw solar system.
Thus the output for each solar panel in your array would.
