Photovoltaic bracket material development history chart

What is solar photovoltaic bracket?

Solar photovoltaic bracket is a special bracket designed for placing, installing and fixing solar panels in solar photovoltaic power generation systems. The general materials are aluminum alloy, carbon steel and stainless steel. The related products of the solar support system are made of carbon steel and stainless steel.

What types of solar photovoltaic brackets are used in China?

At present, the solar photovoltaic brackets commonly used in China are divided into three types: concrete brackets, steel brackets and aluminum alloy brackets. Concrete supports are mainly used in large-scale photovoltaic power stations. Because of their self-weight, they can only be placed in the field and in areas with good foundations.

When was photovoltaic technology invented?

The first paper at a photovoltaic conference was presented in the 12th IEEE PVSC (1976). Only 5 years later, the first consumer products appeared on the market. However, it took quite some time until the basic properties of the material were understood.

What is PV technology development?

PV technology development does not follow the well-know “generations” path. PV technology development is so far characterized by an evolutionary process. Wafer-silicon and thin-film technologies merge to yield the next step in PV. Photovoltaic solar energy (PV) is expected to play a key role in the future global sustainable energy system.

Is silicon a suitable material for photovoltaic conversion?

A large part of the paper is concerned with silicon although from solid-state physics we know that silicon isnot the ideal material for photovoltaic conversion. From the first solar cell developed at Bell Laboratories in 1954 photovoltaics was dominated by silicon. The reasons for this dominating position are investigated.

How big is the photovoltaic market?

Today’s photovoltaic market is about 277 MW (in 2000) corresponding to a value of over US$ 1 billion. This is a remarkable market but still far away from constituting a noticeable contribution to the world energy consumption. Market growth in the last decade was between 15 and 25% as is shown in Fig. 2.
