The solar panel with the highest watt is the sunpower e series a commercial solar panel line.
Commercial solar panel size of 6 kw.
33 kwh 6 1 sun hours x 1 15 efficiency factor 6 2 kw dc solar system size required using the example above with a 6 2 kw dc system you can multiply this number by 1 000 to confirm that you need 6 200 watts of solar panels.
If you want to be spot on 6 66 kilowatts you ll need 370 watt panels as 18 of them will give you that amount exactly.
If you install a 6 kw system with say 20 average sized solar panels expect to occupy a surface of 27 ft.
Obviously you have options for which solar panels to install.
6kw and divide by 8 6kw 8 7 5kw dc.
For example if you select highly efficient 330w panels you will only need 20 of them but if you go for 275w panels you will need 24 of them.
There s no doubt about it the average size of a solar power systemis getting bigger.
The average maximum capacity for solar panels in that range comes to 6 51 kilowatts.
The table below shows a rough idea of the common size of solar panels for commercial businesses and the expected price range.
Solar panels usually range in wattage output from around 250 watts to 400 watts but some panels exceed the 400 watt mark.
This continues to improve ever so slightly but the losses are unavoidable because of physics.
The big question is why.
So if you randomly pick from the most common capacity panels you can expect to get a system size of around 6 5 kilowatts.
This package comes with 24 of these 275w industry leading panels the panels are offered with a 10 year assembly warranty and a 25 year performance warranty so you know your panels will be up to the task for many years to come.
A 6kw installation which you could also call a 6000 watt installation as 1 kw equals 1000 watts would then need 24 solar panels.
Five years ago most households were buying 3kw solar power systems that s approx.
The number of panels you need for a 6 6kw system varies depending on how efficient the panels are.
This means that you ll need 30 250wp solar panels or 27 28 270wp panels.
In a 6 kilowatt solar installation made up of 20 solar panels the panels alone will weigh approximately 800 pounds 20 panels x 40 lbs.
Based on our calculation above we know that this same system measures at 352 square feet which works out to a weight of 2 3 pounds per square foot 800 pounds 352 sq ft.
Long on your rooftop.
If you want the top of the line take a look at solarworld s high efficiency sunmodule panels which produce a very high 300 watts.
Now a 6 6kw solar system sizeis all the go around 24 panels.

A 6 6kw system is typically made up of anywhere between 20 and 24 solar panels.
The top panel in the e series comes out at a whopping 435 watts.
