Solar energy, today, is being produced all over the world. Nonetheless, it is particularly in the regions in which the sun has the maximum power that modules are often exposed to extraordinary stresses. Extreme temperatures and temperature fluctuations, high atmospheric humidity, strong winds and sandstorms.
In several cases, offgrid deployment is also necessary here. J.v.G. has dedicated itself to developing module technologies that are adapted specifically to withstand these extreme conditions.
The Desert Module TechnologyTM achieves with the help of the so called high-power temperature process considerable performance enhancement versus comparable modules.
- High temperature up to 125 °C continuous, 145 °C peak
- Long service life: up to 75 years, guaranteed 45 years
- 100 % recyclable
- Higher yield
- At present, already 5 % more power than conventional modules
- PID free
PID: Potential-induced degradation stands for the voltage-related degradation in power in crystalline photovoltaic modules cause by so-called leakage currents. In case of high system voltages in the region of 1,000 Volts, there may be leakage current in the module, i.e. charge carriers flow through the embedded material and the backside film. This may lead to electrochemical corrosion and thus, causes loss of power in the module.
The effect occurs particularly at high temperatures and high levels of atmos- pheric humidity (see the diagram on the right); it may cause loss in power of up to 80 %.
