Case studies

The Pellworm experience, Germany

The island has a long tradition of harnessing photovoltaic solar energy: there are currently nearly 8,000 m2 of photovoltaic panels installed. In 1983, the first plant was installed (300 kW). This photovoltaic field stopped operating in 1989 and is presently undergoing re-organisation.

In 1992, the new photovoltaic plant was installed. This has exactly the same power and records an annual production of 225 MWh. Given that the photovoltaic plant is integraed with a wind farm, we have one of the largest hybrid systems installed in Europe.

Sun-300: Danish 300 photovoltaic roofs programme

The Sun-300 project involves the installation of 300 PV plants on 300 private houses connected to the electricity grid. The total of 750kWp had been installed from 1998 to 2001.

The budget of the project was 49MDKK (6500k€). It was mainly financed by 37MDDK (4 900k€) from PSO (Public Service Obligation) funds and partially supported by the Danish Energy Agency with 6MDDK (804 k€). The rest, 6MDDK (804 k€) were paid by the householders that got the 300 PV plants installed.

Munich Trade Fair Centre - Local investment in solar energy

Since November 2002 the world's largest roof-mounted photovoltaic (PV) plant is in operation on the roofs of the new Munich Trade Fair Centre. It has been partially financed by a Solar Fund, called Phönix SonnenFonds.

The electricity generated is sold to the public grid on the basis of fixed feed-in tariffs according to the German Renewable Energy Law (Erneuerbare-Energien-Gesetz, EEG) which provides a compensation equivalent to 0.481€/kWh for electricity produced from PV. In addition to that, annual CO2-emissions are reduced by the 2000 tonnes which would have occurred as a result of energy generation from fossil fuels.

Sun-tracking PV solar control louvers at Wirtschaftshof Linz, Austria

The aim of this project was to design a building with a low total energy consumption which, moreover, used renewable energy. At the same time, the working environment was to offer optimal conditions of heat and light. The outcome was an energy-conscious architectural design for the building. View Word document

Photovoltaic Systems for Lighting &Water Pumping.

A Pilot PV Power Plant has been set up at the Institute of Vegetable and Flower Gardening Research (ICLF Vidra), 20 km South of Bucharest, Romania. It consists of two photovoltaic installations supplying electric power to low consumption users.

The PV Lighting System meets the needs of an isolated house for the lights, radio and TV. The PV Water Pumping System operates without batteries, the pump delivering water to the storage tank only there is adequate solar radiation.

The system works with a variable frequency of 7 Hz to 63 Hz which makes it possible to start the pump even under conditions of very low solar radiation.
