Alion Energy Lowers Cost of Solar with Robotic Installation and Cleaning Technology

Robotic Solution Installs Twice as Fast and with Less than Half the Labor

June 17, 2013. Richmond, CA- Alion Energy, an innovative installation and maintenance

service company that uses automated technologies to optimize utility scale solar plants, today
unveils ROVER and SPOT, a pair of patented robotic installation and cleaning technologies.
Together, they enable the fastest construction and lowest EPC costs for utility scale solar
while producing more energy than standard fixed-tilt projects.

ROVER, Alion Energy's automated installation vehicle, and SPOT, their robotic cleaning
solution, are part of Alion Energy's groundbreaking service to build utility scale plants 2x faster
than the conventional installation with 50% less labor required.

"Alion Energy has brought the speed, precision and efficiency of robotics to solar," said Mark
Kingsley, CEO of Alion Energy. "Through using robotic installation and cleaning technologies,
we've eliminated flaws that plague the installation process. Now, we can build plants that are
not only the most cost-effective solution within the solar mix, but have a roadmap to deliver
solar electricity at costs that can compete with any generation source."

Rather than continue the solar industry approach to incrementally fix installation inefficiencies
that perpetuate long construction schedules, tied-up capital and power loss, the company
incorporates established construction industry practices to redesign the entire balance of
system, enabling new levels of automation and cost improvement for utility scale solar.
Alion Energy uses extruded concrete rails to replace metal posts, racks and cable trenches.

Powerful adhesives replace all bolts and clips. ROVER, Alion Energy's robotic installation
vehicle, then works with the concrete rail system to carry and mount panels, using a fraction of
the labor while increasing speed and installation quality.

This new installation process eliminates low-skilled tasks including bolt-tightening, ditch-digging
and hauling heavy glass over uneven ground. High-skill tasks including electrical work, concrete
production, machine and robotics operations are maintained or newly created. Local concrete
suppliers are used instead of shipping metal poles and racks from remote sources. Overall,
Alion Energy's construction process elevates the nature of local, solar installation work.

Once installed, SPOT, Alion Energy's robotic cleaning technology, offers simple and
automated cleaning solutions to prevent double digit performance loss due to soiling. SPOT is
programmable to wash panels at any interval and can be activated from a computer, tablet or
smart phone. SPOT can also manage overgrown vegetation by equipping SPOT with
customized shears.

Alion Energy' robotic technologies and construction practices can work with most photovoltaic
and thin film panels to improve LCOE for utility scale projects. The non-penetrating, concrete
rail system and powerful adhesives are ideal for brownfields and landfills where soil can't be
penetrated, damp environments that can corrode metal and high-wind environments.

BitFlow Introduces 6th Generation Camera Link Frame Grabber: The Axion

BitFlow has offered a Camera Link frame grabbers for almost 15 years. This latest offering, our 6th generation combines the power of CoaXPress with the requirements of Camera Link 2.0. Enabling a single or two camera system to operate at up to 850 MB/S per camera, the Axion-CL family is the best choice for CL frame grabber. Like the Cyton-CXP frame grabber, the Axion-CL leverages features such as the new StreamSync system, a highly optimized DMA engine, and expanded I/O capabilities that provide unprecedented flexibility in routing. There are two options available; Axion 1xE & Axion 2xE. The Axion 1xE is compatible with one base, medium, full or 80-bit camera offering PoCL, Power over Camera Link, on both connectors. The Axion 2xE is compatible with two base, medium, full or 80-bit cameras offering PoCL on both connectors for both cameras. The Axion-CL is a culmination of the continuous improvements and updates BitFlow has made to Camera Link frame grabbers.
