Full wing qualification testing and incremental program update for the solar probe plus array As the Solar Probe Plus (SPP) program moves into the flight hardware build phase, the final testing of the qualification panel has been completed. The rigorous testing is many orders of magnitude more intensive than that used for standard earth-orbit missions. Testing under high irradiance, high temperature conditions over large areas poses design and logistic challenges, which have spurred innovation in steady state illumination. New test hardware of interest include a large area LED simulator capable of 6X AM0 string curre ...

Development and implementation of unique testing methods for the Solar Probe Plus array As a NASA mission to touch the sun Solar Probe Plus (SPP) reveals challenges previously not encountered in space solar panel design and testing. Simulating flight conditions require new testing methods and equipment which have been specifically developed for this unique PV application. Testing under high intensity, high temperature conditions over large areas poses design and logistic challenges, while testing cell performance degradation to a measurement level error of <1% involved fabrication of custom LED simulators.

Predicting the solar probe plus solar array output Predicting the output of the Solar Probe Plus (SPP) solar array presents unique challenges as the array operates at very high temperatures and irradiances, and has a water-cooled substrate. A further complication arises because, close to perihelion, each string operates at an irradiance and temperature different from the other strings. This paper provides the methodology and results for computing the output of the array over a range of irradiances from zero to seventy suns, temperatures from -80°C to 164°C, and angle ...

UV-exposure experiments for the Solar Probe Plus array NASA s Solar Probe Plus (SPP) will travel closer to the Sun than any previous spacecraft. During its 7-year, 24-orbit mission, SPP will make scientific measurements of the solar corona, reaching minimum perihelion at ∼9.5 solar radii (R Boca, Andreea; Blumenfeld, Philip; Crist, Kevin; De Zetter, Karen; Richards, Benjamin; Sarver, Charles; Sharps, Paul; Stall, Richard; Stan, Mark; Published by: Conference Record of the IEEE Photovoltaic Specialists Conference Published on: NASA; Photovoltaic cells; Probes; Radiation effects; Solar cell arrays; Sun; Temperature distribution; Parker Engineering |

Array-design considerations for the solar probe plus mission The NASA Solar Probe Plus (SPP) mission will fly into and study the Sun s corona, reaching as close as 8.5 solar radii from the surface of the Sun. Power generation for the spacecraft will be provided by two solar array wings, which are being designed and built by Johns Hopkins University Applied Physics Laboratory and Emcore Photovoltaics. SPP will get closer to the Sun than any previous mission, and the solar array will therefore need to operate reliably under unusually high irradiances, temperatures, and angles of inciden ...
