new photovoltaic modules Conergy Power Plus

The module is the heart of ' photovoltaic system, the place where electricity is produced. What is wasted here can not be compensated even by the most ingenious design. Therefore, in the production of its modules, Conergy has decided not to make any compromise on quality and aim to continuously improve performance. Conergy modules in Frankfurt Oder in Germany, one of the most modern solar plants in the world, where the integrated chain of production wafer-cell-form, the high level of process automation, and continuous and accurate controls ensure the high quality of finished product. These modules are equipped with special technical features and design that increase performance, functionality and appearance.

modules on the market have a tolerance of power varies mostly between -3% and +3%. This indicates that the effective power of a 200 W module can be up to 6 watts less than the nominal power. This results in considerable economic loss of over 20 years of the photovoltaic incentive: whereas the rate of 0.48 € per kWh, for a 6 kW system, for example, loss of earnings amount to more than 2000 € .

I modules Conergy Power Plus have tolerance power exclusively positive and this ensures that the customer gets not only from the photovoltaic performance and projected revenues, but even better results than those estimated in the draft stage. Tolerance Positive means greater energy efficiency and economic security and greater investment. But not only because the sale price of the modules is based on the rated Wp, the positive tolerance allows you to pay for a given power and have, on average, a more effective power.

The regulations require that the performance of photovoltaic modules are measured in standard laboratory conditions, providing an irradiation of 1000 W / m and a cell temperature of 25 ° C. These conditions correspond to a situation of bright sun and no clouds, which rarely occurs in real operating conditions of the PV system. In foggy or cloudy days, as in the first morning or evening, the average radiation that reaches the photovoltaic module has a value below 1000 W / m and, even in a sunny location, it is estimated that the module works, 80% of the time, with irradiation between 200 and 900 W / sq.m. It 'so obvious that it is more advantageous to use modules with high efficiency values \u200b\u200bin this range of radiation.

Although widely accepted that the efficiency of crystalline silicon solar module is reduced with decreasing irradiance, the modules Conergy Power Plus, in the range between 1000 and 500 W / sq m, have an efficiency curve increasing with decreasing irradiance. between 250 and 999 W / m, also the efficiency is always greater than the standard, measured at 1000 W / m. Under conditions of low irradiance (200 W / m) Finally, the Conergy Power Plus show a relative reduction in the efficiency of 2%, up to three times less compared to other modules on the market, which amounted to values between 4 and 6%.
