Switzerland: Jenni Energietechnik AG expands Production Capacity

Submitted by Baerbel Epp on October 24, 2011

 Storage Production of Jenni Energietechnik AG, Switzerland Orders for large solar storage tanks are on the rise: Swiss Jenni Energietechnik AG is currently expanding its production capacity to meet the greatly increased demand. At its Oberburg headquarters, the solar company is constructing a new building for the manufacturing of large storage tanks. According to CEO Josef Jenni, the additional facility will enable the company to produce five times as much as before.

New IEA Task for Solar Process Heat

Submitted by Baerbel Epp on August 8, 2011

At their meeting in June, the Executive Committee (ExCo) of the International Energy Agency (IEA) gave green light to a new task for solar process heat. The IEA-SHC (Solar Heating and Cooling) Task 49 – “Solar Process Heat for Production and Advanced Applications“ - will start in January 2012 and run for four years. The now rough outline of the task will be further specified in a second “Task Definition Meeting“ at the Solar World Congress in Kassel, Germany, on 2 September 2011. Task participants will then take the suggestions made by the ExCo to spell out the activities for solar process heat in more detail.

Germany: Vacuum Tube Collectors withstand 40 mm Hailstones

Submitted by Baerbel Epp on June 30, 2011

 Hail map of Switzerland” The extra-thick double-glass vacuum tubes by German company Soltark have survived a test with 40 mm hailstones at the Swiss test institute SPF Solartechnik in Rapperswil. A systematic investigation of vacuum tubes at SPF Rapperswil two years ago showed that most of the 26 tested vacuum tube collectors were damaged after several hits with 35mm hailstones. In large parts of Switzerland, however, hail with a thickness of 30 mm must be expected at least once in 50 years (red-coloured areas in the above map). More and more Swiss building insurers are adopting rules for the hail resistance of solar collectors, which the owners hope to incorporate into already existing insurance contracts.

Intersolar Speakers present latest figures of key Solar Thermal Markets

Submitted by Baerbel Epp on June 17, 2011

 Market figures from key solar thermal markets” Several well-known speakers shared their market figures from key solar thermal markets worldwide with the audience of the Global Solar Thermal Markets session at the Intersolar Conference at the beginning of June. Whereas India and Brazil maintain high growth rates, the European solar heating and cooling sector has to again cope with a decline of now 13 % in 2010 compared to the previous year. The chart shows the developments of markets with a volume of 200,000 and 500,000 m2. It is part of the 16-page brochure “Solar Thermal Markets in Europe”, which the European Solar Thermal Industry Federation (ESTIF) presented at the Intersolar.

Launch of ISOL Navigator: Asia moves up, while Europe lags behind

Submitted by Baerbel Epp on June 15, 2011

 ISOL Index of the regions” The ISOL Navigator has been launched at the Intersolar Europe in Munich at the 8th of June. The international study presents the current and future market development in 16 key solar heating and cooling countries. The ISOL Navigator is based on the “ISOL Index”, an international business climate index developed by German agency solrico at the beginning of 2010. This ISOL index is a point-based indicator (ranging from 0 to 100 points) showing the satisfaction of solar thermal manufacturers and system suppliers with current and expected market development. Company values are averaged to obtain country and regional indices.

Swiss: U-turn in Energy Policy

Submitted by Baerbel Epp on May 30, 2011

The 25 May may prove to be a historically important turn in Switzerland's energy policy: The Swiss Federal Council adopted a law stipulating that no new nuclear power stations are to be built in the country. The existing plants could run as long as the Swiss Federal Nuclear Safety Inspectorate (ENSI) certifies they are safe. There are five nuclear power plants in Switzerland. The Swiss Federal Council calculates with each having an overall operation time of 50 years, which means the last power plant, Leibstadt, would be shut down in 2034.

Switzerland: Support Mechanisms differ a lot at cantonal Level

Submitted by Baerbel Epp on February 4, 2011

 Top Ten Subsidies in Switzerland” Last year was the first in which all 26 Swiss cantons have had their own financial support mechanism for solar thermal. For a 5 m² solar thermal system, these subsidies cover, on average, 20% of the investment costs, plus tax reductions that go even up to 40%. But the amount of support does vary a lot. The chart shows the ten cantons with the highest incentive for solar thermal.

„Solar thermal systems are used to improve the coefficient of performance of the heat pump”

Submitted by Baerbel Epp on December 30, 2010

 Dietmar Lange” Has observed the German solar thermal market for decades: Graduate engineer Dietmar Lange had, for many years, been Technical Director at various German collector manufacturers and solar thermal system providers until he became a freelance consultant two years ago. Solarthermalworld.org spoke with him about the technological trends and political developments on the largest European market.

Switzerland: Geneva mandates 50 % solar share in hot water demand

Submitted by Baerbel Epp on December 29, 2010

The Canton of Geneva is the third one after Basel-Country and Vaud to have approved a mandate for a solar share in domestic hot water generation. Article 15.2 of the new energy law, which came into power in September 2010, stipulates that at least 30 % of a building's hot water demand is to be covered by a solar water heating system. This regulation applies to all sorts of new buildings, as well as to extensions and roof renovations of existing ones.
