DESERT®/TROPIC® general information

Operating PV modules in the extreme climates of desert regions leads to potential reliability issues due to environmental stress that could influence all module components. Up until now, PV modules and certifications were optimized to suit the needs of the major PV markets of the past, mainly situated in Europe before 2014.

To reach typical lifetimes of 20 - 25 years in desert regions, the technical configuration and design of PV modules and components must be adapted to the environmental conditions. High stress levels present challenges, especially when the following environmental factors are present:

» High irradiation level, including UV (see below)
» High ambient temperature, also including high temperature changes
» Sand and dust: soiling and abrasion
» Relative humidity
» Mechanical loads (wind speed)

A desert module should be optimized to harness the great potential of the high irradiation levels in solar-rich countries, while also reducing losses due to durability issues. By optimizing the design and materials, while also introducing innovative new technologies such as bifacial and half-cell modules or durable Anti-Soiling Coatings (ASC), we can reach a strong position in the emerging energy markets of our future. The following report describes the main challenges and potential solutions for developing an optimized “DESERT Module.”

High Irradiation

High irradiation generates more current and power in solar modules, but also increases electrical resistive losses. Reoptimizing cell type and size as well as cell interconnectors allows you to increase module power and energy yield. Also, higher irradiation leads to increased module temperature, which reduces the module energy. The passive and active cooling of modules enhances energy yield and module performance.

High UV Irradiation

In the Sun Belt regions, solar modules must withstand higher UV irradiation. Since all polymer materials are generally sensitive to UV illumination, the materials for DESERT Modules must be carefully selected to resist this impact. When using standard module materials, high UV doses can lead to brittle backsheets, as well as the browning of EVA material. The J.v.G. technology Diamond DESERT Foil as well as the DESERT backsheet have excellent durability properties under UV exposure.

Sunlight that reaches the earth travels through the earth’s atmosphere. The optical path from the sun to the equator is shorter than the path from the sun to Northern Europe, so less photons are absorbed by the earth’s atmosphere in the latter region. For this reason, the irradiation is higher in the Sun Belt regions.

High irradiation generates a high current and thereby high power in solar modules. But the higher current also leads to higher resistance in the electrical conductors inside the module and solar cells. In J.v.G. technology DESERT Modules, the solar cells and the busbars between the cells have been optimized to reduce the electrical resistance and thus reach increased module power and energy yield.
