For the plant, solar-modules from the manufacturer First Solar are employed, which are produced in thin-film technology. These modules were selected for this project for many reasons. The First Solar Series modules are less expensive to manufacture and more cost effective than conventional crystalline modules and they generate high energy output under diffuse solar irradiance. First Solar modules are also covered by a collection and recycling agreement that enables the owner to return the modules to First Solar at no cost at the end of the module lifetime for recycling. Thin-film modules are especially suited for large scale solar power plants and free-field installations given the combination of cost effectiveness and area efficiency that is suitable for open-space installations.
For the construction of the plant 144 pedestals were erected, each outfitted with 64 modules rated between 65 and 67.5 watts. The pedestals have been installed on four flat reinforced concrete foundations. The number and the dimensioning of the foundations were designed not to exceed permissible ground pressure which was necessary to protect the landfill liner. Additionally it was important to pay special attention to the sheep grazing on the pasture when designing and installing the module pedestals.
Altogether 9,216 modules with a surface of 6,635.5 sqm have been installed.
The generated power is supplied to the public electricity network via a station with a transformer and two central inverters.
The investment volume of the plant amounts to 2,632,500.00 EUR. After completion at the end of March 2007 the approximately 9,200 solar modules are expected to generate a capacity of about 586,765 kilowatt hours per year, which corresponds to a reduction in carbon dioxide emissions of approximately 438 tons/year.
