Solar Photovoltaic Energy
We can also change the sunlight directly to
electricity using solar cells.
Solar cells are also called photovoltaic cells - or
PV cells for short - and can be found on many small
appliances, like calculators, and even on
spacecraft. They were first developed in the 1950s
for use on U.S. space satellites. They are made of
silicon, a special type of melted sand.

When sunlight strikes the solar cell,
electrons (red circles) are knocked
loose. They move toward the treated
front surface (dark blue colour). An
electron imbalance is created between
the front and back. When the two
surfaces are joined by a connector, like
a wire, a current of electricity occurs
between the negative and positive sides.
These individual solar cells are
arranged together in a PV module and the
modules are grouped together in an
array. Some of the arrays are set on
special tracking devices to follow
sunlight all day long.
The electrical energy from solar cells
can then be used directly. It can be
used in a home for lights and
appliances. It can be used in a
business. Solar energy can be stored in
batteries to light a roadside billboard
at night. Or the energy can be stored in
a battery for an emergency roadside
cellular telephone when no telephone
wires are available

But when most of us think of solar energy, we
think of satellites in outer space. Here's a
picture of solar panels extending out from a
satellite.

Only At Steca
Steca wants to enthuse you with its services and product programme. The great diversity in virtually every field and area of application is typical of Steca. The 3,000 products on the market, which the company offers as an electronics service provider and manufacturer, are testimony to the diversity of the Steca brand. The comprehensive Steca range ensures that your demands are met. This is what the people at Steca are working so hard for. Steca customers appreciate the wide diversity and vertical range of manufacture in all areas. And that's why our customers are not just customers, but business partners of many years standing.
30 years of experience
And not without reason: ever since the company was founded in 1976 – over 0 years ago, that is – Steca has developed inverter technologies and power electronics for heavy-duty operating conditions. Thus, when the German federal government initiated the 1,000 Roofs Programme in the early 1990s, which supported photovoltaic systems nationwide for the first time in Germany, it was easy for the company to make a significant contribution: the majority of the inverters installed at that time came from Steca. The energy sources of the future are renewable. |

SMA Technologie AG was founded as an
independent company out of Kassel's
University in 1981 with the vision
to develop and produce intelligent
computer-based control systems for
decentralized energy supply. This
vision resulted in sophisticated
products that are fail-safe and
extremely reliable. Especially an
energy supply system has to
guarantee long-term trouble-free
operation.
Due to our know-how from 20 years of
experience in the development and
fabrication of system technology for
photovoltaic, wind energy and
combined power generation plants,
continuous product improvements and
the use of absolutely new
technologies, SMA is a pioneer in
the field of solar technology.
With the Sunny Boy inverter SMA are
worldwide market leader in the field
of innovative device technology for
the use of renewable energy sources.
Private, commercial and
institutional owners of solar power
plants rely on our photovoltaic
inverters and the numerous
possibilities of a wide range of
different communication systems. Due
to our own ultramodern electronics
manufacturing we can ensure the
quality, reliability, and up-to-date
technology of the components we are
developing. |
