6 FAQs about [The role of photovoltaic panels on spacecraft]

How do solar panels work on spacecraft?

To increase the specific power, typical solar panels on spacecraft use close-packed solar cell rectangles that cover nearly 100% of the Sun-visible area of the solar panels, rather than the solar wafer circles which, even though close-packed, cover about 90% of the Sun-visible area of typical solar panels on Earth.

Why are solar panels used in NASA's Space Telescope?

Silicon-based solar cells power many of NASA’s spacecraft, including the James Webb Space Telescope. Learn more about why this abundant material is used in solar panels in this excerpt from NASA’s Elements of Webb video series. Silicon is the go-to chip and sensor material for a reason: It works!

How do solar panels work on the SMM satellite?

The solar panels on the SMM satellite provided electrical power. Here it is being captured by an astronaut using the Manned Maneuvering Unit. Solar panels on spacecraft supply power for two main uses: Power to run the sensors, active heating, cooling and telemetry.

How do solar panels & arrays work?

Solar panels & arrays are constructed from individual solar cells connected in series to form strings and in parallel to form circuits mounted on a substrate backing (e.g., figure 3.2). While very low power CubeSats and SmallSats may only need body-mounted solar panels, most will require more power from deployed solar arrays.

When were solar panels first used in space?

The first two sets of solar arrays used by NASA’s Hubble Space Telescope in the 1990s and 2000s were designed with solar cells mounted to a flexible blanket-like material so they could be rolled up and stowed to fit inside the space shuttle cargo bay for launch.

What is a Photovoltaic concentrator solar array?

Photovoltaic concentrator solar arrays for primary spacecraft power are devices which intensify the sunlight on the photovoltaics. This design uses a flat lens, called a Fresnel lens, which takes a large area of sunlight and concentrates it onto a smaller spot, allowing a smaller area of solar cell to be used.
