1.2 Your benefits on a glance

Higher energy yield through Pyramid technology

Excellent partial-load performance

Self-cleaning ability by wind and rain

More longevity due to approved premium- components

Best installation benefits

Eco friendliness



• Use of „extra-white“ glass

• It has an especially low iron content in

comparision with conventional silicate

glasses

• This glass allows it to transmit

excellently the band of the spectrum

that is so important to solar cells, i.e. the

wave lengths starting with visible light,

just below the ultraviolet band



• The specially-formed structures affect

the path of the light and lead to a

higher light yield

• Rays of light which have already been

reflected are refracted again on the

inside of the glass and reflected – with

some being reflected back to the solar

cell in the process

• Thus , up to 7 % more yield can be

achieved



• Meanwhile the second generation of the structural glass

• The latest structural improvements address the behavior of angels of incidence greater than 40°

• At the expense of the rate of increase at extreme angles of around 80°, efficiency is noticeably increased in the interval between 40° and 70°

• This range of angles is more often involved• The result is an even greater net efficiency as

compared to the glass structures used until now


Excellent partial-load performance

In comparison to other polycrystalline solar modules the solar module series

alfasolar pyramid achieves the best energy conversion with middle irradiations,

which seems especially often. Thus the maximum efficiency of the module is

achieved in the area of 200-900 W / m². The modules are output-optimised.


Proven self-cleaning ability by wind and rain

• The structural glass is extremely smooth• It is difficult for dirt particles to accumulate• Dirt is directed into the depresions and is easily removed by wind an rain
