A solar array is nearly in place on the Integrated Equipment Assembly, next to Solar Array Wing-3, which is already installed. Components of the International Space Station, the arrays are scheduled to be launched on mission STS-97 in late November along with the P6 truss. The Station’s electrical power system (EPS) will use eight photovoltaic solar arrays to convert sunlight to electricity. Each of the eight solar arrays will be 112 feet long by 39 feet wide. The solar arrays are mounted on a “blanket” that can be folded like an accordion for delivery. Once in orbit, astronauts will deploy the blankets to their full size. Gimbals will be used to rotate the arrays so that they will face the Sun to provide maximum power to the Space Station

iss060e007151 (July 14, 2019) --- The tip of the Canadarm2 robotic arm (left), or the Leading End Effector, seemingly stares at the camera as the Sun's rays light up Earth's blue atmosphere. At right, a variety of solar arrays criss-cross the view, including the cymbal-shaped Ultra-Flex solar arrays attached to the Cygnus space freighter, a portion of one of the International Space Station's main solar arrays, and (at bottom right) part of a docked Russian spacecraft's solar array.

A rising sun illuminates the coastal waters beyond Space Shuttle Endeavour, poised for launch on Nov. 30 at about 10:06 p.m. EST on mission STS-97. On the left, extending toward the orbiter, is the orbiter access arm. The mission to the International Space Station carries the P6 Integrated Truss Segment containing solar arrays and batteries that will be temporarily installed to the Unity connecting module by the Z1 truss, recently delivered to and installed on the Station on mission STS-92. The two solar arrays are each more than 100 feet long. They will capture energy from the sun and convert it to power for the Station. Two spacewalks will be required to install the solar array connections

This is a view of a solar cell blanket deployed on a water table during the Solar Array deployment test. The Hubble Space Telescope (HST) Solar Arrays provide power to the spacecraft. The arrays are mounted on opposite sides of the HST, on the forward shell of the Support Systems Module. Each array stands on a 4-foot mast that supports a retractable wing of solar panels 40-feet (12.1-meters) long and 8.2-feet (2.5-meters) wide, in full extension. The arrays rotate so that the solar cells face the Sun as much as possible to harness the Sun's energy. The Space Telescope Operations Control Center at the Goddard Space Center operates the array, extending the panels and maneuvering the spacecraft to focus maximum sunlight on the arrays. The purpose of the HST, the most complex and sensitive optical telescope ever made, is to study the cosmos from a low-Earth orbit. By placing the telescope in space, astronomers are able to collect data that is free of the Earth's atmosphere. The HST Solar Array was designed by the European Space Agency and built by British Aerospace. The Marshall Space Flight Center had overall responsibility for design, development, and construction of the HST.

iss052e004379 (6/18/2017) --- The Roll-Out Solar Array (ROSA) is a new type of solar panel that rolls open in space like a party favor and is more compact than current rigid panel designs. The ROSA investigation tests deployment and retraction, shape changes when the Earth blocks the sun, and other physical challenges to determine the array’s strength and durability. ROSA has the potential to replace solar arrays on future satellites, making them more compact and lighter weight. Satellite radio and television, weather forecasting, GPS and other services used on Earth would all benefit from high-performance solar arrays.

Technicians inspect the solar array panel attached to NASA’s Carruthers Geocorona Observatory on Wednesday, July 23, 2025, at the Astrotech Space Operations Facility near the agency’s Kennedy Space Center in Florida. The solar array will use the Sun to help power Carruthers Geocorona Observatory as it operates at Lagrange Point 1 (L1), an orbit point between the Earth and Sun about one million miles away. Carruthers will use its ultraviolet cameras to monitor how space weather from the Sun impacts the exosphere, the outermost part of Earth’s atmosphere. The observatory will launch as a rideshare with NASA’s IMAP (Interstellar Mapping and Acceleration Probe) no earlier than September 2025.

Each solar array is nearly 23 feet long and can turn on two axes to remain aligned with the Sun for maximum power. Orion’s solar arrays, manufactured and installed by ESA (European Space Agency) and its contractor Airbus, will deliver power to the service module that provides propulsion, thermal control, and electrical power to the spacecraft, as well as air and water for the crew.

In the payload changeout room at Launch Pad 39B, STS-97 Commander Brent Jett (left), Mission Specialist Marc Garneau (center) and Pilot Michael Bloomfield (right) pause during a payload walkdown. The payload comprises the P6 Integrated Truss Segment, with solar arrays and batteries that will be temporarily installed on the recently delivered Z1 truss, connecting them to the Unity module. The two solar arrays are each more than 100 feet long. They will capture energy from the sun and convert it to power for the Station. Two spacewalks will be required to install the solar array connections. STS-97 is scheduled to launch Nov. 30 at about 10:06 p.m. EST

NASA and Boeing workers move solar arrays for the International Space Station to flight support equipment in the high bay of the Space Station Processing Facility at NASA’s Kennedy Space Center in Florida on April 2, 2021. The 63- by- 20-foot solar arrays will launch to the International Space Station later this year. They are the first two of six new solar arrays that in total will produce more than 120 kilowatts of electricity from the Sun’s energy, enough to power more than 40 average U.S. homes. Combined with the eight original, larger arrays, this advanced hardware will provide 215 kilowatts of energy, a 20 to 30 percent increase in power, helping maximize the space station’s capabilities for years to come. The arrays will produce electricity to sustain the station’s systems and equipment, plus augment the electricity available to continue a wide variety of public and private experiments and research in the microgravity environment of low-Earth orbit.

The P6 integrated truss segment hangs suspended from an overhead crane that is moving it the length of the Space Station Processing Facility toward a payload transport canister for transfer to Launch Pad 39B. At the pad, the Space Station element will be placed in Endeavour’s payload bay for launch on mission STS-97. The P6 comprises Solar Array Wing-3 and the Integrated Electronic Assembly, to be installed on the Space Station. The Station’s electrical power system will use eight photovoltaic solar arrays, each 112 feet long by 39 feet wide, to convert sunlight to electricity. The solar arrays are mounted on a “blanket” that can be folded like an accordion for delivery. Once in orbit, astronauts will deploy the blankets to their full size. Gimbals will be used to rotate the arrays so that they will face the Sun to provide maximum power to the Space Station. The STS-97 launch is scheduled Nov. 30 at 10:06 p.m. EST

CAPE CANAVERAL, Fla. – At the Astrotech Space Operations facility in Titusville, Fla., spacecraft technicians manually extend a solar array on the Solar Dynamics Observatory, or SDO, during preparations to test the release mechanism sequence for the arrays using signal commands. SDO is the first space weather research network mission in NASA's Living With a Star Program. The spacecraft's long-term measurements will give solar scientists in-depth information about changes in the sun's magnetic field and insight into how they affect Earth.

An Applied Physics Laboratory engineer from Johns Hopkins University tests for true perpendicular solar array deployment of the Advanced Composition Explorer (ACE) in KSC’s Spacecraft Assembly and Encapsulation Facility-II (SAEF-II). The white magnetometer boom seen across the solar array panel will deploy the panel once in space. Scheduled for launch on a Delta II rocket from Cape Canaveral Air Station on Aug. 25, ACE will study low-energy particles of solar origin and high-energy galactic particles. The ACE observatory will be placed into an orbit almost a million miles (1.5 million kilometers) away from the Earth, about 1/100 the distance from the Earth to the Sun
