There’s no question that China is a force to be reckoned with in the solar industry. The country is the largest silicon-based solar-cell producer in the world, with Chinese and Taiwanese production accounting for 39 percent of global production last year, compared with 28 percent from Europe, according to a report the Worldwatch Institute released last week.
But while China had long been considered a potential game-changer in solar, companies’ growth had previously been slowed by a silicon shortage that hit newcomers more dramatically than incumbents. Even so, Chinese manufacturers overtook German and Japanese companies in 2007. Now that plenty of silicon is available, could the country’s dominance grow even larger? Or will some Chinese manufacturers struggle to differentiate themselves and suffer more than the rest of the market during an oversupply of panels?

As U.S. policymakers debate the best renewable policy for the country, many German experts are already convinced they know the answer: a feed-in tariff. Germany’s feed-in tariff, which offers generous set prices for renewable electricity fed into the grid, stimulated 1.5 gigawatts of new solar capacity last year, and similar programs also have boosted markets in countries such as Spain, Greece, Italy, Turkey and South Korea. All the fastest-growing solar markets in the world today have feed-in tariffs.
Gainesville, Fla., and Ontario, Canada, also recently created German-style feed-in tariffs, but the policy hasn’t yet taken hold as a U.S. state or federal policy. I recently wrote a post for Earth2Tech about the difficulties of implementing a German-style feed-in tariff in California: the policy isn’t responsive to market signals that would encourage electricity generation when and where it’s most needed, it’s more challenging to make work in places with lower conventional electricity prices and widely varying utilities with different restrictions, and it doesn’t address retail electricity or encourage customers to use less energy.

A few weeks ago, I visited Intersolar North America, an exhibition for photovoltaics, solar thermal technology, and solar thermal architecture. The exhibition, which was previously only held in Germany, had an understandably large German presence (including a large beer garden). During my time there, I stopped by the German Energy Agency booth, and was quite impressed with what I found. So, without further ado, here are 4 reasons why we should be paying a whole lot of attention to the Germany renewable energy market.
1. Germany has the world’s largest wind power sector— but had barely any notable wind power at all 16 years ago.
With over 20,600 MW of installed capacity, Germany is the world’s wind power leader. And they accomplished this feat pretty quickly, having had less than 100 MW in 1992. The second place wind leader, Spain, only has approximately 12,000 MW of capacity.

Earlier today, I had the opportunity to visit Intersolar US, the United States’ premier exhibition for solar technology. I learned about a variety of products that are revolutionizing the solar industry, and one of the most interesting was Paradigma’s AquaSystem.
The Aqua solar heating system, first introduced in 2004, works like an additional boiler with a selectable temperature. It is the only solar heating product on the market that can be connected to an existing heating system without any modification. Additionally, the AquaSystem does not require frost protection agents in the winter, as it is protected with warm water if temperatures drop below a certain level.

Starting tomorrow, San Francisco’s Moscone Center will play host to Intersolar North America, the country’s premier exhibition for photovoltaics, solar thermal technology, and solar thermal architecture. The Intersolar conference, which has previously only been held in Europe, will attract 210 solar companies and over 12,000 attendees.
Corporate participants will come from every part of the solar energy supply chain—ranging from PV cell manufacturers and components suppliers to service companies and manufacturers of solar thermal applications for heating and cooling.
Not only will the event have a massive exhibition center for the participating companies, but it will also put on a variety of solar-themed workshops. Topics will include solar cooling, solar thermal energy, introductory photovoltaics, and more.
