Solar panels produce more energy in summer than they do in winter.
Average daily kwh generated by solar panels.
This type of solar system would be able to produce 1 kwh per hour of sunlight or 5 kwh per day.
On average a normal household will use around 37 kwh per day.
If you re going by the national average then you should be using about 30 kwh per day.
Next figure out the average amount of sunlight you get per day.
Location and weather conditions.
An average residential solar panel size today is about five and a half feet by three feet.
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.
Let s estimate you get about five hours per day to generate that 30 kwh you use.
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.
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.
In total that works out to about 10 11kwh per day for this time of year.
The table below shows the average daily production of some common grid connected systems throughout australia.
After the energy loss is factored into the equation the total energy production in kwh would be about.
However keep in mind that there are many factors at play here so this is really only a rough estimate.
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.
The amount of power output kwh a 5kw solar pv system grid connected will produce on an average day is 25c kwh.
In the example above the solar panel is producing 1 5 kwh per day which ends up being about 45 kwh per month.
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.
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.
