System-Friendly Agrophotovoltaic-Concept with Vertically Mounted Bifacial Modules
With the increasing expansion of renewable energies, the differences between times of high and low infeed from wind and sun are becoming more intense. This is particularly visible in the morning and evening hours, when the infeed from solar systems is very low. However this reflects the electricity price, which is low or even negative during the day and high in the morning and evening. Renewable energies are in a constant competition with agricultural land or nature and landscape conservation areas. That is why innovative solutions are much-needed.
Next2Sun GmbH, founded in 2015, therefore wants to involve their agrophotovoltaic-concept into developing the energy change in order to add new methods for electricity production. For this new type of mounting, a special frame system was developed which enables the photovoltaic modules to be mounted almost without shadow. The module sides are facing East and West. Prior to the construction of the largest bifacial photovoltaic plant, data was collected over several years with the help of a pilot plant. Thus they were able to build the biggest bifacial photovoltaic system which was brought into service at the end of 2018 in Saarland. It was the first commercial-scale ground-mounted system in Europe. This construction has 5,700 modules on an area of 7 ha and runs with 2 MWp. In addition, Next2Sun has recently built Europe's largest agrivoltaic system with a capacity of 4.1 MWp in Southern Germany.
