Germany stands as the top photovoltaic’s installer in the world and the country has installed numerous solar power plants to reduce the energy needs. Waldpolenz Solar Park is one of the popular solar power plants present in Germany and it is recognized as the biggest thin-film photovoltaic solar power plant at that time. This incredible power system is developed by the German named Juwi in Leipzig. The power plant was built on the east of Leipzig, which served as the former military base. The power plant came to operation in the later part of 2008 and it produces over 40MW power by using the solar systems with thin film technology. This power plant is designed with 550,000 thin film modules of cadmium telluride and it has the capacity to generate around 40,000 MWh power in a year. This power plant was extended to generate 52 MW in the year 2011 by adding some more solar modules. About 153,650 solar panels were added to achieve this higher power and total area used for this project is around 220 hectares.
In 2006, the politician council approved the Juwi’s group project and in 2007 building license was given to Juwi. The solar energy protects the environment and saves the human living through various beneficial factors. The solar power installation is high cost effective and solar energy resource is utilized to fulfill the energy requirements. Around 550,000 solar panels were assembled in 2007 and the first segment of 6 KW is connected to the power grid after four months. In August 2008, more than 30,000 posts were rammed in the ground and 9,000 aluminum frames are assembled. About 385,000 solar power modules were mounted on the frames and wired. The capacity of the power plant at that time of 24 MW, but the overall capacity of the plant is 40 KWh annually. This largest power plant will equalize around 25,000 tons of CO2 every year. All the solar modules for this plant are ordered from Frankfurt and it created over 400 new jobs in that region. Juwi designed the solar modules that work with photovoltaic power plants and now many commercial solar energy projects are utilizing this method.
The CdTe solar modules are proven to yield high energy in all climatic conditions. The Cadmium telluride is highly useful in using solar cells, because of the natural semiconducting property. Few microns are enough to produce high power and these are highly preferred because of its favorable properties like high temperature coefficient and low irradiation. 70 inverters of 500KWh capacity are present in the plant in order to power all the solar cells. Each and every module is connected to the power grid in a step by step manner and transformers substation is located at the distance of 5 km from the solar generator. The solar panels are fitted with the tilt angle of 30 degrees in south direction and the power plant is perfectly designed with operation technology. The Waldpolenz solar park (http://en.wikipedia.org/wiki/Waldpolenz_Solar_Park) is created with the overall budget of 130 million Euros and now this solar park reduced the energy
