University Aims For A Brighter Future With ABB Solar Solutions

ABB is supporting the
sustainability vision of Swiss students from the University of Applied Sciences
and Arts by collaborating on the installation of a next generation roof-mounted
PV installation.

and Environmental Engineering department have supported the installation
incorporating digital capabilities on a campus building at the Brugg-Windisch
site, half an hour's drive north of Zurich.

the aim of the project, developed by the students, was to help the University meet its sustainability targets and reduce its reliance on
the grid.color:#262626"> Several ABB solutions, including ABB Ability and PVS-100 solar
inverters were used to help maximize the efficiency of the complex PV
installation across the flat roof buildings and challenging structures. Stefan Roth, Lecturer, Energy and Environmental Studies said:
"The technology we have available today is very well suited to capture
renewable energy. Our students realized that the potential of solar combined with
digital data was huge and wanted to create a sustainable and holistic energy
consumption model for our university "“ supporting the university today and the
students of the future."

support the campus' electricity needs and reviewing the significant challenges
presented by several roof top obstructions including heating, ventilation
systems and chimneys, the students planned an installation of 756 solar modules
on the site in an east-west set-up, each orientation connected to their own
PVS-100 inverter.

said: "The students at the university are at the forefront of a change. More
and more businesses, public sector buildings and homeowners are moving away
from the traditional energy consumption model. They are looking at
how electric energy is produced, when it is used and how to effectively reduce
the cost. Digitalization and smart inverters such as the PVS-100 are essential
technologies to support this transition by improving yields and making
this information tangible."

color:#262626">The PVS-100 is a three-phase string inverter solution for cost
efficient decentralized photovoltaic systems. Its power range and the cloud
connectivity provide the unique features to stand out in a highly competitive
market.

color:#262626">Launched earlier this year as part of the wider PVS inverter
portfolio, the PVS-100 delivers a six-in-one, sun-to-socket solution, proven to
deliver scalability, flexibility, proactive plant management and ease of
installation through the ABB Ability™ Installer for solar inverters App.

color:#262626">Full digitalization and proactive control and management was a
pre-requisite of the PV technology for the University students, particularly as
the principle aim was to improve self-consumption of the energy produced from
renewables on campus.

color:#262626">ABB Ability™ provides a unified digital platform connecting the
students with devices, systems and products such as the PVS-100 inverter and
enabling them to harness the power of the Internet of Things (IoT), delivering
data insights for proactive plant maintenance and energy management.

color:#262626">At the Brugg-Windisch site, ABB Ability™ provides the students
with a real-time view of how much energy is being harvested at peak times
and when they can use it for heating and cooling systems.

color:#262626">Roth continued: "Having a holistic view over our PV plant
allowed us to take advantage of seasonal variations and improve energy
self-sufficiency of the campus to 3.5 percent, using the energy only when we
needed it. This is one of the biggest advantages that digitalization can offer
in creating a sustainable energy model for today and tomorrow."

color:#262626">It is predicted, that the PV installation of 230kWp will provide
at least 1/30 of the 6 million kilowatt hours the campus requires on a yearly
basis. Via sophisticated self-consumption optimization, 99 percent of the PV
electricity can be used at the campus.

Switzerland are confident that renewable energy from solar will create a
powerful energy model for the next generation.
