Solar power costs closing in on wind: Wynn

May 16 (Reuters) – Solar panels were cheaper than wind turbines for the first time last year in certain markets, per unit of capacity, and are rapidly closing a remaining gap in the full cost of power generation.

Until now, wind power has been the leading low-carbon alternative to oil, coal and gas, outside large niche markets such as Germany, which has seen a huge ramp-up in installed solar.

But that could change, with deep implications for the health of both industries if one substitutes the other.

As soon as this year, solar could for the first time surpass wind in annual global installed capacity, given an expected contraction in the wind market.

Solar Boat Harnessed for Research

Last year, after it became the first solar-powered boat to circumnavigate the globe, the Turanor Planetsolar could have taken its 5,500 square feet of photovoltaic cells and eight tons of lithium-ion batteries and sailed off into the sunset.

Instead it is becoming a scientific research ship, at least for the summer. The boat, a 100-foot, $17 million catamaran that was dreamed up by a Swiss eco-adventurer and bankrolled by a German businessman, will cruise the Gulf Stream studying the role of atmospheric aerosols and phytoplankton in regulating climate, under the direction of Martin Beniston, a climatologist at the University of Geneva.

The research cruise, with five crew members and up to four researchers aboard, began in Miami several weeks ago and will stop in Newfoundland and Iceland as it tracks the northeasterly current. The voyage is expected to end in Bergen, Norway, in August.
