Problems solved by technology

[0007] The problem with such colored photovoltaic modules is that it is difficult to manufacture colored glass panels to achieve the desired relative efficiencies
The inventors have found that this is particularly problematic for multi-coloured glass panels, since the different colored areas often lead to different relative efficiencies, which ultimately lead to so-called hot spots when applying photovoltaic modules, i.e. PV units in this area receive significantly more solar radiation
The formation of such hot spots is very detrimental to the application of photovoltaic modules, especially leading to short-term performance losses
In addition, the formation of hot spots can also lead to long-term and lasting damage to photovoltaic modules

Embodiment Construction

[0072] figure 1 The photovoltaic module P according to the invention is shown in a top view. The photovoltaic module P comprises a glass panel (no reference number provided) which in turn comprises six coloured areas, namely white area 1, yellow area 2, red area 3, green area 4, blue area 5 and black area 6 . The six coloring areas are individually colored, each of which applies one of the six primary colors of white, yellow, red, green, blue, and black. Among them, the primary color black is "NCS S 9000N Glossy", the primary color white is "NCS S 2502B Glossy", the primary color blue is "NCS S 4550R80B Glossy", the primary color red is "NCS S5040Y80R Glossy", and the primary color yellow is "NCS S 3050Y20R Glossy" ”, the primary color green is “NCS S 5040G10YGlossy”.

[0073] In order to make the solar energy impinging on the solar cells provided with the glass panels constant over the entire surface of the photovoltaic module P (or in other words: to generate a substantia...

Abstract

Glass panels for photovoltaic modules (P), comprising at least one tinted area (1,2,3,4,5,6), the opacity of the selective tinted area (1,2,3,4,5,6) ( D) to achieve the desired relative efficiency (RE).

Description

technical field [0001] The present invention relates to a glass panel, as well as a photovoltaic module, a computer-implemented data structure, a storage medium and two methods. Background technique [0002] Photovoltaic modules are currently used in many places. One possible application site for photovoltaic systems is building facades, in this case also known as BIPV applications, BIPV means "Building Integrated Photovoltaics". [0003] In such BIPV applications, the goal is not necessarily to generate current as efficiently as possible with the photovoltaic modules used. Conversely, when integrating photovoltaic modules on building façades, aesthetic aspects also play a decisive role in approving building projects. [0004] In this case, colored photovoltaic modules are especially required. Colored photovoltaic modules typically include colored glass panels rather than clear glass panels. [0005] The use of colored glass panels instead of clear glass panels reduces t...
