Professionals in trade and brokerage – from A to Z


Sustainable electricity production with photovoltaics

Die Green Finance Broker AG

is a sister company of Green Finance Capital AG and provides management, administration and consulting services.

This includes above all the trade with goods of all kinds, including for the most part components related to renewable energy generation with solar power.

The Group

Green Finance Broker AG is also responsible within the Green Finance Group for invoicing and the control and administration of payment transactions.

The broad range of activities forms the structural basis for the success of the Green Finance brand and all corporate divisions.

The sun as a source of energy

The sun occurs in the form of global radiation, it breaks through the atmosphere and hits the ground with an incredible energy density of 1,000-1,400 watts per square meter.

With more than 1.5 million megawatt hours of light per day from ultraviolet rays, 23,000 times more energy could be generated than is actually needed annually worldwide.

Free energy that needs to be used.

Why Photovoltaics?
Why now?

Electricity from photovoltaics is healthy, protects the environment, relieves the purse and pays for itself in the long term. Air pollution and electrosmog have increased radically in the last 60 years. In 2016, our emissions will be around 25% higher than they were in 1950.

The serious effects can already be seen at this stage. Global warming is rising steadily – a fact that is already noticeably affecting Austria.

Fossil fuels are exhaustible, relevant electricity reforms are planned from 2019, rising prices are to be expected.
It therefore makes sense to invest in your own energy supply. It minimises dependence on network providers and is a first step towards self-sufficiency. Self-produced electricity from photovoltaics is available free of charge, so you are not exposed to any price fluctuations.

Thanks to the most innovative technologies, it is already possible today to cover a large part of one’s electricity requirements with an in-house system using hot water production components and solar energy storage tanks.

For a long time, the purchase of a photovoltaic system was considered expensive, but the prices for high-quality, high-yield and thus profitable PV systems have fallen by over 65% in recent years.

Today, an average of 1,400 euros is paid for a kWpeak output. The amortization time of a system – the time it takes for the acquisition costs to balance out with the electricity cost savings – can now be minimized to just 6 years with the help of appropriate PV equipment.

This makes photovoltaics a variant that is also attractive, interesting and affordable for private households.

Sustainable, conscious, pollutant-free

Green Finance focuses on sustainable and consciously chosen values. Clean environment means quality of life, healthy consciousness is our key topic.

Photovoltaics offers pollutant-free generation of solar energy. Austria is a sunny country with a lot of green space and natural resources – these must be preserved.

By avoiding air pollution and electrosmog, every photovoltaic owner and green electricity consumer can make a valuable contribution to preserving Austria’s green beauty.

What is photovoltaics?

The photovoltaic effect was first discovered in 1893 and correctly interpreted by Albert Einstein in 1905. This is a particle movement provoked by light rays – an interaction of photons with matter. This conversion converts light into electrical energy and generates electricity.

By means of photovoltaic modules it is possible to use this energy and to supply one’s household efficiently, sustainably and cleanly with it.
One can consume one of the most natural and inexhaustible energy sources of our planet: the sun.

It is possible to benefit from this exploitation of resources in several areas. A photovoltaic system is a sensible and environmentally friendly way of generating energy. This saves costs in the long term and makes you less dependent on price fluctuations and price policy changes in the electricity tariffs of various network providers.

The photovoltaic process

Briefly explained: During the migration of electrons – small electrically charged particles – a process is initiated by light and heat.

The element of silicon in the modules releases photons from light radiation and stores them.

This process produces energy that can be used as direct current and fed into the domestic power grid.

Electricity is used in Austria as alternating current – household appliances such as cookers, washing machines or entertainment electronics are supplied with interacting energy and kept in operation.

Here an inverter is the current regulator – it converts the direct current obtained into household AC current and supplies all the appliances in the house.

photovoltaic modules

Solar cells mainly consist of the practically inexhaustible raw material silicon. Silicon can be found, for example, in the earth; the element is particularly densely contained in sand.

It possesses a broad spectrum of light and absorbs light. In an infinite circuit, the semiconductors contained in the light release electrons from the light radiation. A change of electrons takes place in a conduction and valence band.

The movement cycle enables the generation of energy to a finite extent. Silicon is a very robust element that guarantees long-term, reliable energy generation.

A module is the bundling of several solar cells. 60 solar cells result in a module with the most commonly installed size of 1.65 square meters. Each cell measures a square format of 15.6 x 15.6 centimetres.

Polycrystalline modules are the most frequently used because they offer the most efficient bandwidth in terms of price and performance.

module structure

Solar modules are cast in plastic. In order to protect against external factors, a lightweight aluminium frame is used that securely surrounds the complex inner workings of a module.

To protect the collector from the effects of the weather, there is another layer of tedlar or polyester inside the frame. This construction ensures the best possible fixation of the complex interior and prevents or minimizes damage.

In the innermost core, embedded in plastic, is the silicon, which is connected with solder blades. It is the most important part of a module, the entire energy production process takes place in the mono- or polycrystalline cells placed here.

This sensitive module layer is further surrounded by a refined Plexi safety glass. This not only ensures that the module is more stable, it also protects against contamination.
