2. With SolTech Sigma, we have created an
efficient, tidy and simple solar energy system
for single homes as well as for large residential
and commercial buildings. With SolTechs
own thermal absorbers, especially developed
for our specific glass roof tile, installation is
simple and overall system efficiency is high.
An efficient, attractive and smart solar
energy system
Combined with SolTechs award-winning design and
concept solution, we can now offer a solar energy
solution that is both effective and elegant, SolTech
Sigma, the energy efficient smart roof. The roof of
most buildings, annually receive many times more
energy from the sun than is being consumed in the
building! With SolTech Sigma you can benefit from
that energy, save money and get a beautiful new roof
for your building at the same time!
Simple and Ingenious
Instead of traditional roof tiles made from concrete or
clay, we use our specific SolTech tiles made of glass.
The glass tiles are installed on the Sigma Modules,
SolTechs specially developed liquid based absorber
modules. The modules have an integrated, patented,
carrying batten for maximized absorber surface as well
as simple installation. The modules are interconnected
on the roof to form a complete solar collector system.
Generated solar energy is stored in the SolTech Therm
Accumulator tank which is connected to the building’s
central heating system. This configuration enables
the use of all the energy the sun provides first and
the central heating system will step in to provide
heating for those times when the sun does not pro-
duce enough energy.
A flexible system
The system can be integrated with any water borne
central heating system or hot water system with ease,
regardless of heating source.
The highest efficiency is obtained when the roof is
straight facing south, but southwest and southeast also
works very well. The optimal roof pitch varies from every
location, but generally a pitch of 30-60 degrees is recom-
mended for Europe. Our minimum recommended pitch
is 22 degrees. If you have a roof pitch less than this, do
contact SolTech Energy for the design of an appropriate
solution for you.
Each installation is tailored to the specific building.
SolTech Sigma can be installed on the entire roof or part
of the roof, depending on customer needs and wants.
When part of the roof is used as solar collector surface,
we offer the customer a solution where the rest of the
roof is covered with SolTech Power, our solar electric
solution, or passive glass roof tiles for an aesthetic and
uniform solution.

4. SolTech Techo Solar® is our solar thermal
module that combines the function of a
roofing material with an effective solar energy
solution. It is designed primarily for cement
and brick based roofs which fits construction
methods that are commonly used in the
Mediterranean countries, Latin America,
North Africa and many other countries.
The SolTech Techo Solar® (Solar Roof) is a patented bio-
climatic architecture product with multi functionality.
Primarily it’s a building material, which can cover any
type of building. Secondly it’s a solar thermal system
that maximizes the active area of the roof area. The
result is a configuration which maintains the classic
style of a tiled, sloped roof while also generating
clean renewable energy.
Simple and Ingenious
Instead of traditional roof tiles made from concrete or
clay, we use our specific SolTech tiles made of glass.
The glass tiles are installed on the Techo Solar Modules,
SolTechs specially developed liquid based absorber
modules. The modules have integrated, patented,
carrying battens for maximized absorber surface as well
as simple installation. The modules are interconnected
on the roof to form a complete solar collector system.
Generated solar energy is stored in the SolTech Therm
Accumulator tank which is connected to the building’s
central heating system. This configuration enables the
use of all the energy the sun provides first and the
central heating system will step in to provide heating
for those times when the sun does not produce
enough energy.
A flexible System
In the same way as our SolTech Sigma System the
Techo Solar® System can be integrated with any water
borne central heating system or hot water system with
ease, regardless of heating source.
The highest efficiency is obtained when the roof is
straight facing south, but southwest and southeast also
works very well. The optimal roof pitch varies from every
location, but generally a pitch of 30-60 degrees is re-
commended for Europe. Our minimum recommended
pitch is 22 degrees. If you have a roof pitch less than
this, do contact SolTech Energy for the design of an
appropriate solution for you.

As a building material the Techo Solar® System can
save considerable amounts of money on conventional
materials whilst building, repairing or laying a roof.
The System is designed to be part of the buildings
structure, with the option that it can either integrate with
conventional tiles (classic ceramic or traditional concrete),
or cover a full surface independently, depending on
design, available area and energy needs for the building.
Due to its light weight, 60 kg/m2
, its application is
extensive and can range from porches, roofs, covered
terraces, garages, car parks etc.
The bottom layer of the Techo Solar® is a high den-
sity insulation which keeps the energy conserved in the
system, improves the overall energy efficiency of the
building and is the part of the system that facilitates
modular installation.
The intermediate layer is made up of the solar
collector and the hydraulic circuit, through which flows
the heat transfer fluid and functions as the energy
collection element of the system.
Finally the top layer, which is the visible layer, is the
SolTech Energy Glass Roof Tile. Its high transparency
molded glass acts as a water proofing element, creates
a sealed chamber for optimized function, allows the solar
radiation to pass through and provides the architectural
aesthetic of the product.
Combine SolTech Techo Solar
and SolTech Power
You can produce the electricity needed from the sun to
run pumps, control system etc. i.e. all peripheral systems
in SolTech Techo Solar®.
You can also expand the system by combining
SolTech Techo Solar® and SolTech Power with a heat
pump, creating a completely energy neutral solution.

8. High Efficiency Ratio
SolTechs Supreme has a high,12%, performance ratio,
comparable with traditional crystalline silicon cells.
Better in diffused light
SolTech Supreme cells have a much higher efficiency
and yield in diffused light like dusk, dawn and light over-
cast. The SolTech Supreme solar cells work in a much
wider spectrum of light that may be converted into elec-
tricity than traditional crystalline silicon cells, this result
in SolTechs Supreme also producing electricity
in diffused light.
Less sensitive to high temperatures
A traditional crystalline silicon solar cell loses approx.
0.48 % in output for each degree C that the panel tem-
perature rises above 25° C. In clear sunlight with warm
temperatures, the panel temperature will rarely be as
low as 25° C, but rather 2, 3 or 4 times that or even
more. SolTech Supreme will lose only approx. 0.21 % for
every degree C. For this reason, SolTechs Supreme will
have a higher output in higher temperatures than that of
traditional solar cells.
More kWh/W – Better ROI
The combination of high efficiency ratio (12 %), higher
efficiency in diffused light and less sensibility to high
panel temperatures results in that more energy, kWh,
is produced per installed watt than traditional solar cells.
Tests show that for regions like Scandinavia, Germany
and southern China (same parallel as northern Africa),
5 – 10 % more energy is produced per W installed than
for a traditional solar cell facility of equal output. That
provides for a better ROI on the system.

9. SolTech Energy is proud to present SolTech
Supreme ST. ST stands for Semi Transparent.
This is a whole new way of combining solar
energy with solar shading.
With SolTech Supreme ST, SolTech Energy is now able
to present a sustainable, intelligent and aesthetical
solution for the combination of solar energy and solar
shading. By applying the thin film in very narrow rows in
the module, a shading effect is achieved, like sun glasses.
Solar Shading and power generation
at the same time
Through integrating the solar shading into the glass roof,
the need for air conditioning in the building reduces.
However, if the shading can make use of the solar energy,
an even greater benefit is reached. SolTech Supreme ST
will therefore reduce cost on air conditioning through
power generation!
Tailored solar shading
SolTech Supreme ST can be ordered with different levels
of transparency, ranging from 90 % to 10 %. Since the
need for shading may be higher for a glass roof, a low
level of transparency may be chosen for more shading
whereas a façade solution might require a higher level of
transparency allowing for better view through the window.
One of a kind solution
With its revolutionary concept of combining a renewable
energy source with semitransparent shading, SolTech
Supreme ST is the natural choice for glass roof applica-
tions, store windows, winter gardens, atriums, shopping
malls, patios and other buildings where you want to
have; the light, the view, solar energy and less air condi-
tioning needs. SolTech Supreme is truly a one of a kind
solution and the only solution for many buildings.
Insulated glass module
In addition to offering a solar shading solution, SolTech
Supreme ST may also be ordered as an insulated glass
module. For buildings where there is a heating need and
there are insulation requirements on the windows, the
Supreme ST module can be ordered as an insulated
module with argon filled spacing and a U-value of 1.3.
Simple installation
SolTech Supreme ST can easily be installed using
leading aluminum glass roof or glass façade systems
for creating a water proof and insulated climate.
Through the use of leading suppliers of these systems,
a global network of installers and suppliers can be found.
It also facilitates for architects and designers to intro-
duce these systems into future buildings and projects.

11. The SolTech Roof Tile
Stylish, strong and effective
The SolTech glass roof tile is designed as part of SolTech Energy’s solar energy
system, but also does the job of a traditional roof tile, protecting the building.
The tile is manufactured of highly transparent glass with low content of iron
oxide and has a double bend.
The design enables the SolTech tile to be fitted together with various
complementary products made for traditional concrete tiles, such as specific
fittings, seals, gaskets etc.
Appearance
Low level of iron oxide gives the tile a light silver or gray tone, influenced
by the color of the underlying material (absorber) and the sky when installed.
The surface of the SolTech tile is smooth and corresponds to that of
glazed tiles.
