Outstanding Solar Projects

GOLDBECK Solar GmbH - Landfill Hellsiek

Goldbeck Solar designs, constructs and services ground-mounted PV and rooftop systems across Europe. The company was founded in 2001 as a subsidiary of the construction group Goldbeck GmbH. The photovoltaic system on the Hellsiek landfill-site in Detmold, Germany, functions as a seal for the landfill in a project that combines conventional waste management and climate protection. This is the first time a PV system has been used on such a large scale to seal a landfill. The hybrid solution conserves resources, and is more cost-effective than conventional installations. The landfill is sealed by the PV system, preventing seepage and contamination of clean rain water in the landfill. This type of renewable energy generation is a landscape and ecologically-friendly option for supplying renewable energy. The construction also enables double use of the landfill site for energy production. The jury was impressed by the high level of innovation, and the use of standard and cost competitive PV components in an innovative and important application. This scalable solution helps to prevent over 7,000 tons of CO2 emissions per year.

Next Kraftwerke GmbH - Bridging the Gap - A Virtual Power Plant for Constant Power Supply

The German company Next Kraftwerke operates one of the largest Virtual Power Plants (VPP) in Europe. It aggregates 4,200 medium and small scale power-producing and power-consuming units with a combined capacity of nearly 3,000 MW in its VPP Next Pool. More than 650 MW of photovoltaics are included in the trading portfolio. By digitally networking thousands of renewable energy installations all over Europe, the VPP Next Pool bridges the intermittency gap. The VPP can forecast the output and track the status of each single installation with the help of live data from the installations. By scaling up Next Pool over the last five years, dramatic enhancement of the quality of PV forecasting for the photovoltaic share was achieved. Next Kraftwerke added live data to the equation, and the central control system collects data from every networked unit through interfaces with over 15 inverter manufacturers. The jury awards this project for the relevance of its business model in designing regulatory frameworks that will help establish renewable energy at high penetration levels as it develops the future of global energy delivery.

> Phaesun GmbH - University of Hohenheim (Joint Submission) > Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH - Solar Powered Cooling for Enhancing Milk Value Chains

This project was developed at the request of the Deutsche Gesellschaft fuer Internationale Zusammenarbeit (GIZ) by the University of Hohenheim and their technology partner Phaesun. Phaesun specializes in sales, service and installation of off-grid photovoltaic and wind energy systems in Europe, Africa, Latin America and the Middle East. They have developed a system that uses solar energy for milk cooling that is based on conventional DC refrigerators being modified into smart icemakers. This is done by aligning cooling-power demand with the hourly solar energy resource, and by substituting batteries with thermal energy storage in the form of ice. The ice-maker produces 12 to 16 kilos of ice per day. A storage volume of 50 kilos of ice will last for four days. The system allows for raw milk to be stored overnight and transported to collection centers without compromises in quality that would otherwise lead to milk rejection and income loss. The potential social and economic impact of the project and its design as a business case were of special importance to the jury in rewarding this project with the award. The system is especially designed for the needs of farmers in rural areas.

RAM Pharma - Solar Process Steam Generation at RAM Pharma in Jordan
