Solar

To date standard solar modules can convert only a certain range of the solar spectrum into electrical energy. Due to its very special characteristics that applied by us, nanocoating bundles all incident radiation. This has already been shown in laboratory scale and successfully implemented. This is realized in an area of 5 x 3 cm, and covers the hole Module.

 Monocrystalline or polycrystalline - Which module type is better? This question can not be answered, because it depends on the application.

The difference is first of all the crystal structure: polycrystalline cells consist of disks, which do not have everywhere the same orientation of the crystals. They are such prepared as by casting. With an efficiency of up to 20 percent, monocrystalline solar cells are the most efficient solar cells in direct sunlight. They are very good, if only a small roof space is available or if a very high performance must be achieved. However, monocrystalline modules are relatively expensive due to their complex manufacturing. And: with diffuse light diminishes their power. This is particularly in roof areas, which are not directly aligned to the south, this is a disadvantage.

Polycrystalline modules mind are not quite as high efficiency, but they are much cheaper. That's why they are the most commonly installed modules also at the moment. It is characterized by its crystal structure; polycrystalline solar modules lets the sunlight strongly reflecting.

SolarModul "Desert" Polycristaline

General advantages of the Desert modules

  • High temperature up to 125 ° C continuous, 145 ° C peak
  • Long life: up to 75 years, guaranteed 45 years
  • 100% recyclable
  • No PID Effect

 PID: potential induced degradation represents the voltage-related performance degradation in crystalline photovoltaic modules, caused by so-called leakage current. At high system voltages ranging from 1000 volts can cause leakage currents in the module, i.e. it flowing charge carriers through the potting material and the back sheet. This can lead to electrochemical chemical corrosion and thus to a loss of performance of the module. The effect occurs especially at high temperatures and high humidity; it may cause power loss of up to 80%!

 Our modules are available in the variants 240 watts, 245 watts, 250 watts, 255 watts, 260 watts, 265 watts, 270 watts.
