The sun as an energy source

The sun appears 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 metre.

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

Free energy to be used.

Why photovoltaics? Why now?

Why photovoltaics? Why now?

Electricity from photovoltaics is healthy, protects the environment, relieves the wallet and is profitable in the long term. Air pollution and electrosmog have increased radically over the last 60 years. In 2016, our emissions were already about 25% higher than in 1950.

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

Fossil fuels are exhaustible, pertinent electricity reforms are planned since 2019, and rising prices are expected.
It therefore makes sense to invest in an in-house energy supply. With this investment you minimize your dependence on network providers and take the first step towards self-sufficiency. Self-generated electricity through 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 ones electricity requirements with an in-house system using water heating components and solar energy storage units.

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

1,400 Euros is the average price for a kWpeak output. The payback period of a system – the time it takes to balance the purchase costs with the electricity cost savings – can now be minimized to only 6 years with the help of appropriate PV-equipment.

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

Sustainable, conscious, pollutant-free

Green Finance focuses on sustainable and deliberately chosen values. A clean environment means quality of life, and healthy consciousness is our primary key topic.

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

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

What is photovoltaic?

What is photovoltaic?

The photovoltaic effect was first discovered in 1893 and correctly interpreted by Albert Einstein in 1905. It is a particle movement provoked by light rays – an interaction of photons with matter. During this conversion, light is converted into electrical energy and electricity is generated.

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

It is possible to benefit from this exploitation of resources in several sub-areas. A photovoltaic system is a sensible and environmental friendly way of generating energy. You save costs in the long term and become more independent of price fluctuations and changes in the pricing policies of various network providers.

The photovoltaic process

The photovoltaic process

In short: The migration of electrons – small electrically charged particles – results in a process initiated by light and heat.

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

This process generates energy which can be used as direct current and fed into the domestic power supply system.

Electricity is used as alternating current (AC) in Austria – household appliances such as cookers, washing machines or consumer electronics are operated with alternating current.

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

PHOTOVOLTAIC MODULES

PHOTOVOLTAIC MODULES

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

It has a broad recording spectrum and absorbs light. In an endless cycle, the semiconductors it contains release electrons from the light radiation. A change of electrons takes place in a conduction and valence band.

The motion cycle allows energy to be obtained in finite quantities. Silicon is a very robust element, it ensures long-term, safe energy production.

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

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

MODULE – CONSTRUCTION

Solar modules are encapsulated in plastic. To protect against external factors, a lightweight aluminium frame is used to securely enclose the multi-layered inner life of a module.

To protect the collector from the weather, there is another layer of Tedlar or polyester inside the frame. This construction ensures that the complicated interior can be held in place in the best possible way and damage can be excluded or minimised.

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

This sensitive module layer is further surrounded by a refined plexiglass safety glass. The safety glass not only increases the stability of the module, it also protects against contamination.
