The module comes with an energy management system (EMS), which monitors the amounts of electric power generated by the 28 CPV units, via commercial power networks which are stored in a redox flow battery, and consumed at an office or plant to manage the electric power flow. Obtained data is sent by optical communication networks to be collectively controlled at the central control server. This system will be used in the demonstration test held at the Yokohama to achieve optimal supply-demand balance (maximum demand control of 1 MW) and power demand control based on preset schedules.
Solar Junction announced in February a $19.2 million round, as well as an exclusive manufacturing agreement with IQE. Coupled with the SunPath award, Solar Junction is on the path to high volume manufacturing of its proprietary adjustable spectrum latticed matched (A-SLAM) cell.
Emcore secures $6 million solar panel contract
The provider of compound semiconductor-based multi-junction solar cells has been awarded a manufacturing contract by Ball Aerospace & Technologies Corporation
Emcore Corporation has been awarded a contract by Ball Aerospace & Technologies Corporation (BATC) to design, manufacture, test and deliver solar panels for a new spacecraft.
The program is expected to last arouund 2 years, with a total contract value of nearly $6 million.

Solar Junction to use DOE cash to improvise its III-V
solar cell research The SUNPATH award is aimed at expanding the firm’s CPV cell manufacturing in the US and is aimed at 42% median cell efficiency on 150mm substrates
Solar Junction, a developer of high efficiency multi-junction solar cells for the CPV market, has been given a SUNPATH award from the Department of Energy (DOE) as part of a $21.5 million program to increase its CPV cell manufacturing capacity.
Through this program, Solar Junction is targeting a median cell efficiency of 42% on 150mm substrates. These factors will make a substantial impact on reducing CPVʼs $/W module costs by driving down the cost of the cell, while increasing the CPV module power output with increased cell efficiency.
«It is an honour to be in such a select pool of SUNPATH awardees through the SunShot program,» says Jim Weldon, CEO of Solar Junction. «This allows Solar Junction to move into the next phase of commercialization and will allow for a path to volume manufacturing.»
SUNPATH, Scaling Up Nascent PV at Home, falls under the Department of Energyʼs SunShot Program. This program aims to increase PV manufacturing in the U.S. through investments in technologies that are sustainable with competitive cost and high performance. SunShot investments are designed to help achieve $1/W by 2020.

The solar panels delivered to BATC will utilise Emcore’s ZTJ multi-junction solar cells. The ZTJ is currently one of the highest performance space-grade solar cells available in volume production to the global market. Production of the solar cells and panels will take place at Emcore’s manufacturing facilities located in Albuquerque, New Mexico, USA.
“We are very pleased to receive this award from Ball Aerospace & Technologies Corporation and recognise their confidence in our capabilities to manufacture and deliver the solar panels for this important mission,” says Christopher Larocca, Chief Operating Officer for Emcore. “Our proven manufacturing capability, technology leadership and high-reliability solar panels make Emcore the supplier of choice for demanding spacecraft power systems.”
Emcore is a global manufacturer of highly-efficient radiation- hard solar cells for space power applications. With a beginning- of-life (BOL) conversion efficiency close to 30% and the option for a patented, onboard monolithic bypass diode, Emcore’s multi-junction solar cells provide high power to interplanetary spacecrafts and earth orbiting satellites.
