What Size Solar System Do I Need For My House

The average australian household consumes 18kwh of electricity each day.

What size solar system do i need for my house.

So for example to cover the energy needs of a typical home in california you would need a 4kw solar power system to generate 6 522 kwhs of electricity. Calculate the size of your solar system. The numbers vary mostly because of the climate of each region. We listed the solar system size that would be needed in each region to offset that particular region s average electricity usage.

Roughly sizing up a solar system is easy. How many solar panels do i need to power my house. To calculate the size of your solar photovoltaic system take your daily kwh energy requirement and divide by your peak sun hours to get the kw output you need. Solar power can save you around 400 per kw per year and a solar system will output around 4 times its size as a daily average.

Total number of solar panels. Then divide the kw output by your panel s efficiency to get the estimated number of solar panels you ll need for your system. 3 x 1 3 3 9in this example you would need a 3 9 kw solar pv system to satisfy your home s energy needs. If we use a house in adelaide as an example you would need a 5kw solar system to generate this amount of power.

To figure out how to size your solar system take your daily kwh energy requirement and divide it by your peak sun hours to get the kw output. For example a 5kw system will output around 20 kwh a day and may save you up to around 500 every quarterly power bill. To get these numbers we used high and low panel production ratios to calculate how many solar panels are needed on average.
