Every age bracket and educational group has specific
needs and different learning methods.
To ensure a maximal learning success for every user,
the leXsolar-product families are divided into different
product series.
leXsolar
Small
Series
leXsolar
Medium
Series
Kindergarten and
Elementary School
Middle school
Junior high school
Children have a natural
desire to research and want
to discover the world around
them. At the same time, the
basis of school education
is set in kindergarten and
elementary school. Connect
those two aspects and let
children discover the topic
of renewable energies with
playful experiments.
As a result, children are able
to develop an early awareness for renewable energies
and learn how they function.
In secondary education, knowledge developed from elementary school is deepened and
consolidated: initially it is
experience-oriented working
and later becomes more and
more scientific. Both can be
achieved with the products of
the leXsolar Medium line.
With the aid of experienceoriented experiments, inspire
your students and increase
their attention. At the same
time, students are motivated
to follow scientific experiments.

Designed for the youngest
but already big in application – these are the products
of the leXsolar Small Series.
Simple experiments and playful
learning take priority, which
is why the experiments are
all self-explanatory. In the
enclosed brochures you can
find background information
easily comprehensible even for
those without a scientific background. The products can be
used by the hands of children
as well as adults, and at the
same time they are robust, so
that they will last for a long
time against the eagerness of
experimentation.
Compact in size, competitive
in price and with a wide range
of application, the leXsolar
Medium series offers you a
mixture of simple qualitative
and challenging quantitative
experiments. The provided
instruction manual contains
extensive background information and operating instructions.
The products of the leXsolar
Medium series are delivered in
sturdy plastic boxes. Common
school supplementary equipment like measuring devices
and cables are not included.

Ready-to-go
Series
Secondary school
For flexible users
High Schools prepare for an
university education as well
as an engineering one. To
meet these requirements
you can carry out practicallyoriented experiments regarding scientific elements of
the renewable energy technologies.
A special feature of the
leXsolar Large series is the
modular design to extend the
fields of application to further
grades or topics.
„Ready to go“ – the name says
it all. Everything is enclosed in
a robust aluminum case and
ready to use at any time – at
or even out of school. For this
reason all necessary accessories, such as measurement devices and cables, are
included.
The leXsolar Large line is adapted
to the latest curricula and is
ideally suited for the application
within scientific teaching. For
this reason, leXsolar-PV Large
won the Worlddidac Award. The
products allow mainly quantitative student-based experiments and deal especially with
the physical basics of particular
renewable energy technologies.
In school, available auxiliary
equipment such as multimeters,
cables or similar are not included.
Like the leXsolar Large series,
the Ready-to-go- series
offers a wide area of different
experiments – from simple
entry-level experiments to
more challenging advanced
experiments.
All in one, immediately
and everywhere, these are
the keywords, which best
describe the Ready-to-go
series. It is the most flexible
solution for all users: schools,
industry or associations.

basics of PEM-Fuel cell technologies on the basis of diverse demonstration
experiments.
Topic
H2
1
For this reason, leXsolar-H2 Demo can be optimally used as an introductory
explanation of the experiments. Within the teacher-centered instruction, the
leXsolar-H2 Demo replaces student experiments completely. Altogether more
than 20 experiments from chemistry and physics education are possible.
SOFC-Fuel cell module powered by eZelleron
Item-No. 1218-01
In cooperation with the technology company eZelleron,
leXsolar now offers the world’s first SOFC-fuel cell for
educational purposes! SOFC stands for „solid oxide
fuel cell” and is already used today for the commercial
generation of electricity.
The big advantages that set it apart from the
PEM-technology are the high efficiency, the independence from expensive resources like platinum and
the ability to work directly with natural gas or biogas
instead of pure hydrogen.
eZelleron has developed a SOFC-technology that, in
contrast to previous SOFC-cells, can start faster and
allows a high number of operating cycles. These cells
are also ideal for educational purposes.

leXsolar-SmartGrid
leXsolar-SmartGrid Small
Item-No. 1601
The leXsolar-SmartGrid Small combines solar energy, wind energy and storage
possibilities in one product. That is why students from elementary school up to
13 years old are able to gain knowledge about the basics and applications of these
technologies. Another highlight of the product is its curriculum-based theme of
energy and energy conversion for experiments.
The product requires no external voltage source – neither a power supply nor a
battery. Students will gain the required energy with a hand generator. The further
available leXsolar-LearningApp SmartGrid Small + connects the real experiments
with digital learning contents. (see p. 70)

leXsolar-Smartmeter works like a real
intelligent electricity meter. Depending
on the energy supply, it can switch
consumers on or off and keeps the grid
stable and the electricity not expensive.

Electronic vehicles are an important part of
the SmartGrid of the future! They work as a
decentralized “storage fleet”.
This is where all data come together:
current energy production, available storage
capabilities and the energy consumption.
These kind of information enable students
to manage their grid by themselves. The
communication works wireless with
SmartControl technology (see p.14). The
integrated platform-independent software
allows the control with any mobile device.
In a real household, different consumers
play different roles different times. Thus,
their behavior corresponds to a specific

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.
