Next figure out the average amount of sunlight you get per day.
Average daily kwh generated by solar panels.
Solar panels produce more energy in summer than they do in winter.
The table below shows the average daily production of some common grid connected systems throughout australia.
A typical australian house consumes around 18 kilowatt hours kwh per day so a 1 2kw system displaces an average of 25 40 of your average electricity bill.
This time of year you can reasonably expect around 3 kilowatt hours kwh per kilowatt kw of solar capacity assuming that your roof faces due north and has no shading and that your system loses about 15 in energy yields due to inefficiencies.
On average a normal household will use around 37 kwh per day.
The us ranges from about 4 hours 6 hours of sunlight per day on average see the below map.
It is estimated that 1kw of solar panels can generate up to 1321kwh of electricity annually and on average 3 62kwh of electricity per day see the calculator on this page for more details.
That s enough energy to power some small appliances without too much issue but if you want to cover the energy used by your property s climate control systems or large cooking appliances you ll need more solar panels.
An average residential solar panel size today is about five and a half feet by three feet.
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.
In the example above the solar panel is producing 1 5 kwh per day which ends up being about 45 kwh per month.
Clean energy council a body government of australian charges with accrediting solar cells inverters and installers is one of the most comprehensive sources providing this information.
You must simply divide the average daily kwh by the peak sun hours assuming a 30 day month an electricity generation of 1 000 kwh is equivalent to 33 33 kwh per day if the site gets 6 peak sun hours per day you need 5 56 kilowatts.
Let s estimate you get about five hours per day to generate that 30 kwh you use.
If you re going by the national average then you should be using about 30 kwh per day.
In total that works out to about 10 11kwh per day for this time of year.
After the energy loss is factored into the equation the total energy production in kwh would be about.
Location and weather conditions.
This type of solar system would be able to produce 1 kwh per hour of sunlight or 5 kwh per day.
