Space Assemblies are space solutions with a higher integration level. In order to provide additional capacity to the CubeSat it is possible to add deployable solar panels to the spacecraft deployed along the long edge of the spacecraft and these can be single, double or even triple deployable depending on customer power requirements. The panels are equipped with CESI Solar cells of type CTJ30, with up to a 29.5% efficiency, and are designed to maximise the available effective cell area. For individual mission requirements specific solutions can be developed, both in terms of electrical performances and specific panel shape and cutout.
To generate power this thickness is not needed, and since Ge is a rare expensive material – amounting to around 30% of cell cost – research teams are working on a technique to remove and recyle this substrate. Differing doping ingredients are used on either side of a semiconductor junction to create an electrical potential. Through such design strategies, current solar cells on geostationary satellites still retain 88% of their original performance after 15 years resulting in an absolute end-of-life efficiency of 24.6%.". The PVP series is available with a deployable option in order to maximise power input for the satellite platform.
Space qualified triple junction GaAs solar cells with integrated magnetic coils, sun sensors and temperature sensors.
Development of the first-generation SSS (SSS-1) was completed in 2010. An optional, embedded and configurable magnetorquer (MTQ) is available, along with up to 4 separate RBF circuits. The models have extensive flight heritage and are thoroughly tested under different launch loads and at various temperatures. This includes long- and short-axis deployment on 3U, 6U, 8U, 12U and 16U CubeSats. The products are: 3U Solar Array - with solar array power from 28 to 42 W and bus voltage of 6.18 VDC. To minimise the harmful effects of space radiation – mainly energetic electrons and protons – all solar cells are covered by cover glass, typically just 100 micrometres (0.1 mm) thick.
Space missions would also gain increased power and performance without having to go through the extensive and expensive process testing of a new design with solar arrays having to be qualified for space.
A 1U CubeSat for example will have an area of just 10 cm x 10 cm on each face in order to accommodate a solar panel. Informatie Gestuurd Optreden is pure noodzaak. "They are all needed to monolithically integrate the three power-generating junctions and to ensure that the maximum amount of light enters the solar cell and is not reflected at the surface. The panels primarily use Spectrolab XTJ-Prime solar cells but AAC Clyde Space also has experience working with AZUR and SolAero alternatives. The panels are space-proven and have been deployed from LEO to GTO orbits. "Some of the really big bird telecommunication satellites have arrays of 100 square metres or more so this would be a really significant mass saving.". Solar cells are assembled using NASA-qualified low outgassing adhesive materials in cleanroom environments.
NanoAvionics also provides customised deployable solar panels. ISIS provides a range of high-performance CubeSat compatible solar panels. Here are a few tips and tricks on how to integrate a panel efficiently with other sub-systems in order to gain more value than simply generating power: Traditionally smaller satellites have not had deployable arrays to generate more power for advanced missions or more power-hungry payloads. DHV Technology manufactures solar panels in a range of sizes with both standardised and custom models available. The panels are body-mounted on aluminimum substrate and include sun and temperature sensors. Based on our high-efficiency solar cells of the 28% or 32%-Advanced class, the assemblies are additionally equipped with cover glasses and interconnectors.
Solar cells are made from the same kind of semiconductor materials as integrated circuits. 1U CubeSat solar panel Z - utilising two highly-efficient triple junction solar cells and supporting multiple integrated sensors. Featuring efficiencies of 18.0–29.5% and output power of 880–1200 mW/Cell, the space-qualified solutions can be customised to suit different mission requirements, with a variety of cell, substrate and testing options available. In this post we give a brief overview of satellite solar panels and arrays, sharing listings of multiple products available on the global marketplace - if you would like to skip the introductory material and instead get straight to the product listings, please click here. 3U solar panel - double deployable solar panels with 29.6 W power (4 x strings) and weighing approximately 410g. The panels come in 1-6U size with sun and temperature sensors and other custom options available on request. 6U/12U solar panel - CubeSat-compatible solar panels available in customised sizes and in honeycomb substrates, polyimide and aluminium. It is possible to embed magnetorquers that can be configured to provide different levels of torque and power consumption in order to comply with different mission profiles. Trace impurities are added to a semiconductor to alter its electrical properties – a process known as 'doping'. The solar cells reach up to 29.5% efficiency and contain bypass diodes to protect in-series connected solar cell strings from shadowing effects or individual cell failure. In spite of these limitations there are several different solar panels available on the market, featuring a variety of solar cells for space applications, which work with the severe physical restrictions imposed by smallsats and the CubeSat (and smaller) form factor. In this program, EIC proposes to develop ultralight space qualified "dye sensitized" solar cells (DSSCs) that will have even higher specific power as well as potentially being much less expensive to manufacture than the inorganic thin film alternatives. In the list below we have rounded up a range of commercially-available satellite solar arrays and panels on the global marketplace for space.

Designing the connections between cell junctions therefore requires a great deal of expertise and innovation, he adds: "All layers must be matched regarding the current flowing through the cells to avoid efficiency losses, even though the junctions have different current density capabilities, and which change over time because space radiation degrades the individual junctions at a different rate. Networks of sensors and sub-systems can be seamlessly integrated with the solar panels, including sun sensors, magnetorquers and gyroscopes.
Designed and qualified for maximum power generation and ease of platform integration, the Photon panels aim to provide maximum power generation from any side of the satellite. They include an MCU for simple, decentralised access and have a mass of 43g, 69g or 97g respectively for the 1U, 2U and 3U models. Send us an email today today we’d be happy to work with you to showcase it to the satsearch community! They feature the Pumpkin Modular Deployable Solar Array System (PMDSAS) and all-cell / interconnect / coverglass (CIC) construction with triple-junction cells.
Unlike larger satellites where the surface area available on the external structures is much greater, CubeSats, nanosatellites and other small satellites have far less volume that can be given to solar panels. If a bare cell was exposed to the space environment it would degrade as much within a few days as … All GaAs-based multi-junction cells are also vulnerable to so-called 'reverse voltage bias' – when part of the array is covered by shadow, as might occur during a manoeuvre or a particular orbital season then electric surges can damage the array. "This would cut costs but more importantly reduce solar cell mass by something of the order of a kilogram per square metre," explains Mr Gerlach.
