Top Ten PV Manufacturers from 2000 to Present: A Pictorial Retrospective

Tue, 01/21/2014 - 08:26

From 2000 (shipments of 252 MWp), through 2013 (estimated shipments of 33.4 GWp), PV industry shipments to the first buyer have grown by a compound annual 46 percent, albeit not always profitably and almost always with slim margins. During this period a cumulative 123.2 GWp was shipped, and most of this shipment was installed.

Renewable Projects Strong Enough to Attract Investment, Says IRENA

Tue, 01/21/2014 - 07:02

Germany Energy Minister Proposes Cuts to Renewable Subsidies, Industry Reacts

Mon, 01/20/2014 - 13:22

German Energy Minister Sigmar Gabriel is scheduled to propose renewable energy reform on Wednesday. In an effort to reduce government spending and slow the increase in energy costs, Gabriel proposes to cut subsides for renewable sources from €0.17 per kilowatt-hour (kWh) to €0.12 per kWh by 2015, according to several reports.

Solar Beats Natural Gas to Unlock Middle East’s Heavy Oil, Says GlassPoint Solar

Mon, 01/20/2014 - 10:23

Solar energy is cheaper than natural gas in powering enhanced oil recovery projects in the Middle East that tap heavy, viscous forms of crude, a developer of the technology said.

Designing and Achieving Geothermal Power Plant Performance with Confidence

Mon, 01/20/2014 - 09:07

The design and the actual performance of a geothermal air-cooled power plant utilizing a supercritical refrigerant of R134a as the working fluid are discussed. A supercritical Organic Rankine Cycle (“ORC”) in many cases outperforms a sub-critical cycle, from the net kilowatt (kW) generated point of view. Additionally, the plant configuration is simpler to design and easier to operate. An additional advantage of using non-flammable working fluid in the cycle, such as R134a, eliminates the risk of fires. During the design stage, a preliminary process flow diagram is established based on the standard process engineering practices in HYSYS, a simulation software from ASPENTECH.

$41 Million in Loans Announced for Renewable Energy Projects in Developing Countries

Mon, 01/20/2014 - 08:13

Loans of $41 million were announced for renewable energy projects in six developing countries by the International Renewable Energy Agency (IRENA) and the Abu Dhabi Fund for Development (ADFD).

Cleantech's Investment Cycle: Don't Worry, Think Bigger

Mon, 01/20/2014 - 03:00

Several reports this week agree that cleantech investments fell in 2013, but that's not a bad thing. And the big question is what happens next: how much more is needed?

Does A European PV Fab Make Sense?

Fri, 01/17/2014 - 16:39

Reports came out this week that Germany, France, Switzerland, and possibly other European nations are mulling a plan to pool efforts and establish a combined massive-scale solar cell manufacturing operation, inspired by the aerospace consortium Airbus. The concept has been kicked around for a few years now, most recently at last fall's EU PVSEC con

Listen Up: Brad Mattson with Siva Power Talks Thin Film Solar PV

Fri, 01/17/2014 - 13:24

Thin film solar technology is compelling: a way to make panels in a continuous or large batch fashion instead of assembling and gluing individual cells to the back of glass. But with very few exceptions (notably First Solar), more thin film companies litter the solar graveyard than any other product category.

What If You Went Solar and Nobody Noticed? Spotlight Solar Has an Answer

Fri, 01/17/2014 - 12:17

Normally I don’t write about solar products, since this blog is devoted to solar marketing and solar advocacy. But I’m making the exception this week for Spotlight Solar. Spotlight’s not a typical BIPV solution, but a working aesthetic solar structure that’s also a green PR solution that calls attention to hidden solar. For example, say you're the

Trident in Marine Control Technology Optimisation Breakthough

Fri, 01/17/2014 - 09:56

Generator company Trident Energy has demonstrated real-time control of a low cost linear generator designed for wave energy applications.

UK Solar, Wind to Compete Head-to-Head With Solar Under Auction Plans

Fri, 01/17/2014 - 09:54

The U.K. plans to force onshore wind developers to compete head-to-head for the first time with solar generators when they bid for green power subsidies as the nation seeks to reduce the cost of renewable energy for consumers.

Sun Still Rising on Residential Solar

Fri, 01/17/2014 - 07:42

There is much evidence pointing to a rosy future for residential solar.  High retail utility rates provide a compelling reason for homeowners to go solar while residential installation costs continue to drop.  Many of our partners claim that residential system development is more profitable than commercial development. Even solar developers that hi
