Average Daily Kwh Generated By Solar Panels

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.

Average daily kwh generated by solar panels.

Next figure out the average amount of sunlight you get per day. The us ranges from about 4 hours 6 hours of sunlight per day on average see the below map. On average a normal household will use around 37 kwh per day. The amount of power output kwh a 5kw solar pv system grid connected will produce on an average day is 25c kwh.

This type of solar system would be able to produce 1 kwh per hour of sunlight or 5 kwh per day. 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. The table below shows the average daily production of some common grid connected systems throughout australia. 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.

Solar panels produce more energy in summer than they do in winter. Let s estimate you get about five hours per day to generate that 30 kwh you use. 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. After the energy loss is factored into the equation the total energy production in kwh would be about.

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. 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. Remember if you are receiving an average of four hours of usable sunshine per day and your solar panel is rated at 250 watts of power then you will need forty panels to reliably generate 1 000 kwh per month. However keep in mind that there are many factors at play here so this is really only a rough estimate.

If you re going by the national average then you should be using about 30 kwh per day. 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. An average residential solar panel size today is about five and a half feet by three feet.
