Each of the panels are 9 feet 2 7 meters wide by 29 feet 8 9 meters long.
Juno solar panel area.
So the total area required is 30 000 200 150 m 2.
Juno s 19 000 solar cells are arranged into three panels that fold out to be 2 7 meters wide by 3 9 meters long and the total area covered by cells is apparently 60 square meters.
Shortly after it cleared earth s atmosphere the panels were deployed.
Juno s three solar arrays are 2 9 meters wide and 8 9 meters long and consist of 11 individual solar panels one arrays features the magnetometer boom instead of an eleventh solar panel.
Launched in 2011 juno is the first solar powered spacecraft designed to operate at such a great distance from the sun.
The thousands of reddish blue solar cells are located on 11 panels four on each on two of the spacecraft s 250 pound wings.
Three solar panels extend outward from juno s hexagonal body giving the overall spacecraft a span of more than 66 feet 20 meters.

Lets assume the solar panels have 20 efficiency so the energy produced is 200 watt m 2.
With solar arrays deployed juno s span is about 20 meters.
It has 72 square metres 780 sq ft of panels.
The four ton juno spacecraft carries three 30 foot long 9 meter solar arrays festooned with 18 698 individual solar cells.
Nasa says in earth orbit they will produce around 14 kilowatts which means they would only operate at about 23 efficiency rather than their maximum of 28.
Three solar panels extend outward from juno s hexagonal body giving the overall spacecraft a span of more than 66 feet 20 meters.

One of the three arrays is only 2 091 meters wide due to launch vehicle limitations.
Two of the panels have four hinged segments each and the third panel has three segments and a magnetometer.
Each of the panels are 9 feet 2 7 meters wide by 29 feet 8 9 meters long.
The third wing has three panels and is outfitted with a boom at the end that carries the spacecraft s magnetometer.
The juno mission launched in 2011 is the first mission to jupiter arrived at jupiter on july 4 2016 to use solar panels instead of the traditional rtgs that are used by previous outer solar system missions making it the furthest spacecraft to use solar panels to date.
To calculate the area you need to know the efficiency of the solar panels.
Share a few details about your project.
The juno spacecraft uses three solar panels symmetrically arranged around the spacecraft.
