leXsolar-PV Professional offers experiments for both electrical engineering and
photovoltaic. But the main focus is on laboratory experiments on photovoltaic
systems. Thanks to the modular setup, the specific characteristics of single
components can be analyzed in detail, such as the switching threshold of series
or shunt regulators. Because of the integrated manual mode, the included MPP
tracker enables a descriptive understanding of the really important principle
of the MPP tracking. With the help of the PWM regulator the principle of pulse
with modulated charging can be demonstrated. In addition, an inverter displays
the generation of alternating current out of a solar panel current. The product
is completed through a variety of different electrical consumers such as a super
bright LED or a light bulb, which can be used to compare their efficiency. A radio,
which can be powered by the solar panel, helps to increase the attention of
students.
The area of expertise leXsolar-PV connects the technical and physical
basics as well as the required knowledge to understand PV-systems
and their components.

Item-No. 1607
Understanding the complex interactions between renewable energies, energy stores
and consumers is an important goal in the vocational and technical education sector.
leXsolar-SmartGrid Professional allows the construction of a controllable Smart grid
on a laboratory scale. Pre-set or user-created scenarios, let the students gradually
develop their knowledge and understand by themselves with their own experiments.
Measuring and Control are accomplished with the help of the leXsolar-SmartControl
components. With the SmartControl software, all parts of the Smart Grid can be
controlled extensively.
As students set up a real grid and not just a simulation, realistic incidents can happen,
like the sudden loss of a wind power plant. Students now need to make sure that all
consumers are supplied according to predefined priorities.

„We have tried several times to make photovoltaic and renewable energy accessible to students. leXsolar
has made it possible through the development of cases and experiments according to the different types
of education and curricula, in cooperation with teachers and our solar experts. This sponsoring gave us the
opportunity to offer these cases at a competitive price. With leXsolar we found a reliable and competent
partner at our side.“

with a multitude of companies and energy providers,
we take part in the success of renewable energies.
Many years of experience, high quality standards
and a great innovative potential allowed us to realize
educational projects with many partners. Now, we’d
like to develop a project with you! For example:

the experiments with their students and find out solutions by themselves. We are pleased to announce that in
the year 2014, we will set our focus on e-mobility, battery technology and its application in storing renewable
energies with the “leXsolar-EStore Ready-to-go” and enable schools to experiment with different battery

„We, as long-standing leXsolar customer, are always impressed by the competitive, reliable service and the
customer assistance. We use photovoltaic experiments for the training programs of DGS solar school, but
even in other general education schools. There´s no better way to explain to engineers and students how
solar technique works. We are glad to show you some experiments with solar cells, that we are able to carry
out thanks to the leXsolar cases.“

innovation
and quality
made in Dresden
The source of innovation and quality …
of the leXsolar products is located in the capital of
Saxony and not without reason. In Dresden you
can find both qualified scientific centers and an
unique cultural scenery.
Ten universities and colleges, three Max Planck-,
four Leibnitz- and eleven Fraunhofer-institutes
are accompanied by numerous competence
centers and facilities for the transfer of
technologies.
On the other side, Semperoper, GrünesGewölbe,
Sächsische Staatskapelle or the Frauenkirche
offer an unique cultural richness.
Through this inspiring background, it is possible to
develop further ideas that will help you and your
students to understand new energies.
