Switzerland: Rising Interest in PVT Technologies

Submitted by Baerbel Epp on June 1, 2017
PVT CaotecThe Swiss-based SPF - Institute of Solar Technology has recently published a report on behalf of EnergieSchweiz, a programme by the Swiss Federal Office of Energy, about the market situation of PV-thermal technologies (PVT) in Switzerland and across all of Europe (see attached document in German). The researchers from SPF have found that there are various market-ready and proven products available. They counted around 300 PVT installations in Switzerland alone. A particularly good example is shown on the photo: a PVT installation integrated into the facade of an office building.

Switzerland: Solar Thermal Market Decline, Unclear Policy Situation

Submitted by Baerbel Epp on July 28, 2016
In 2015, the solar collector area newly installed in Switzerland shrunk by 16 % compared to 2014. Imports outperformed domestic production, and larger systems for multi-family and commercial buildings, particularly those with vacuum tubes, have gained market shares. These are some of the key findings of the annual study published by the Swiss Federal Office of Energy (see attached study in German and French). Some cantons will completely halt incentives for solar heat because of budget restrictions. 
 

Switzerland: Shift towards Multi-Family Housing Projects

Market development SwitzerlandIn June, the Swiss Federal Office of Energy published its annual solar market report carried out by the solar energy association Swissolar (see the attached document in German and French). In 2014, sales of glazed collectors dropped by 7 %, down to 113,000 m² of absorber area. Vacuum tube collectors had a share of 13 %. The statistics also include 4,487 m² of unglazed collectors. The chart shows the shares of the different collector technologies over the years.

Switzerland: Parabolic Trough Collectors Produce Heat for Dairy

Submitted by Baerbel Epp on September 22, 2014
LESAewz’s latest solar project as an energy service company (ESCO) is the solar plant at dairy company Lataria Engiadinaisa SA (LESA), which is located at an altitude of 1,700 m in the Swiss Alps. With its 115 m² of parabolic trough collectors by NEP Solar, the solar plant heats thermo-oil up to a temperature of 180 °C in order to provide heat for steam production. The investment of Swiss Franc (CHF) 500,000 was jointly financed by the Swiss Federal Office of Energy and ewz. The heat is sold to LESA at the same full cost as steam production by the dairy´s installed oil boiler. The project won the Swiss Solar Prize in 2012.

Storage Solution for Solar Thermal Energy (2004)

Submitted by Raquel Ponte Costa on May 31, 2011

This is a study concerning solar storage technologies and materials presented by J. C. Hadorn from the Swiss Federal Office of Energy. Many schemes and graphics provide a visual explanation of how all presented technologies work and how they can be connected to different energy supply technologies or with energy grid.Some schemes of potentially useful materials for this function thanks to their energy densities are also available.
