수상태양광 알프스 호수에 들어서다.

기후온난화에 대한 심각성을 세계 주요국가들은 생존의 문제로 대하고 있다. 이를 반증하는 기사가 있어서 발췌를 한다.

해외에서 바라보는 수상태양광 산업을 일견할 수있는 기사이다. 구조선말에서 보던 일이 오늘 날 사회 곳곳에서 발견되고 있는 지금, 시간이 주는 경고와 기회의 신호를 독선과 오만으로 망기해선 않될 것이다. 한국의 독보적으로 개발한 기술이 세계시장을 선도하고 청정에너지의 새로운 페러다임으로 자리매김할 그날을 기대한다.

Photovoltaics go for a swim in the Alps:

Can solar installations on reservoirs help close Switzerland's winter electricity gap?

Switzerland's first floating solar power plant in the Alps was installed on Lac des Toules rerservior in the canton of Valais.

In winter, Switzerland often faces the threat of a power supply bottleneck. How can this be solved? Among other things, the federal government is relying on photovoltaics: the amount of solar power generated is to be increased almost tenfold by the middle of the century compared to today. That's what the Energy Strategy 2050 states.

For this reason, operators of new solar systems receive a one-time reimbursement of up to 60% of the investment costs – provided that the modules can produce a defined minimum amount of electricity during the winter months.

This is achieved primarily with photovoltaic systems installed in the high mountains. For one thing, they benefit from many hours of sunshine in winter, as the sites are far less likely to be covered in fog and clouds during these months than those on the central plateau. In addition, the reflection of incident solar radiation by snow and ice increases yields. Modules are able to achieve this feat with solar cells, thanks to a special treatment, that can also utilize the radiation reflected from the ground that hits their rear side. Last but not least, the colder the environment, the more efficiently solar cells work.

Controversial solar plants in Valais

Utilities, renewable energy companies and local stakeholders are currently planning several large-scale plants in the high mountains. For example, near Grengiols in Valais, a total of 160,000 modules are to be installed there at an altitude of up to 2,500 meters. The plant is expected to generate enough electricity to supply around 37,000 households. In nearby Gondo, a solar park is currently being designed at a similar altitude to supply electricity for a good 5,000 households.
