Estimated number of solar panels needed.
How many solar panels to make 5kw.
How many solar panels will you need.
For example you could install an 8kw fronius inverter and export limit it to 5kw.
Premium high efficiency solar panels produce more electricity so you re able to install fewer panels particularly useful if your roof is small.
Each panel will be about 1 6m x 1m so you ll need at least 17 2m of roof space.
If you are considering solar energy for your home you may also be asking how many panels are needed to power specific appliances.
However it is important to understand how solar.
To give you a feel for how big 17 2m is this picture may help.
The number of panels that make up a 5kw solar sytem varies depending on the quaity and output of the single panel.
So you can usually add 6 6kw of panels to a 5kw inverter and still respect the 5kw system size limit.
With an average 250w panel you will need 20 panels to make up a 5kw system.
At 265 watts you d need 19 solar panels to make up 5kw.
To make up a 5kw solar system you need 17 solar panels assuming you use 300w panels that will actually give you 5 1kw.
Further you may even be able to add a bigger inverter and export limit it to 5kw for an even larger panel array.
5kw or 5 kilowatts is 5 000 watts of dc direct current power.
A 5kw solar kit requires up to 400 square feet of space.
Solarworld produces some of the best solar panels on the market and their sunmodule plus enjoy a capacity up to 300 watts.
