Evergreen Solar Inc (ESLR) announced a major advance in the development of its String Ribbon(TM) manufacturing process that has the potential to produce silicon wafers thinner than 150 microns. The Company has filed a patent application for its thin wafer technology. "Evergreen Solar's mission since its inception has been to produce high-quality solar products at a fraction of the cost of conventional methods," said Richard M. Feldt, President and Chief Executive Officer. "Today we are announcing an important step in realizing that goal. With the latest enhancement to our Gemini II double ribbon growth process, Evergreen Solar has...

Worldwater Corp (WWAT) unveiled the world's largest solar-powered irrigation pumping system during a commissioning ceremony at Seley Ranches, Borrego Springs, CA. WorldWater's proprietary and patented AquaMax(tm) system drives a 200 horsepower pumping system at the Seley Ranches facility. The 267 kW system is grid-connected, and can operate independently from the solar array, from the electrical grid, or from both sources if necessary. This also allows the system to ``net meter,'' that is, return excess solar electricity to the utility for credit if it is not required in the field.

Joe Romm, at the influential Climate Progress blog, has hit on a formula for countering the coal industry's claims that we need baseload power sources.  Since Concentrating Solar Power (CSP) in conjunction with thermal storage can be used to generate 24/7 or baseload power Joe has renamed it "Solar Baseload."   This is win-the-battle-lose-the-war thinking.  While it does neatly counter the argument we need coal or nuclear, since there are renewable power sources which can produce baseload, such as CSP, Geothermal, and Biomass.  I fell into this coal-industry trap myself in a 2007 article about Geothermal, as did AltEnergyStocks...

by Clean Energy Intel Source: NPD SolarBuzz, SolarBuzz Quarterly. New survey-based data from SolarBuzz points very clearly to a very much needed ongoing adjustment to manufacturers planned module shipments. The chart above illustrates the issue very succinctly. In SolarBuzz´s survey conducted in Q2 of the current year, manufacturers were still planning on shipping just over 8 GW of modules in Q3 of this year and almost 9 GW in Q4. The somewhat obvious result was oversupply, a continued inventory build and falling module prices. However, in the latest...

John Petersen Last week I had the pleasure of participating as a panelist in Infocast’s Storage Week and attending four days of presentations by industry executives, national thought leaders and policymakers. While most of the presentations were too detailed and specific for a blog about energy storage stocks, there were a few high-level discussions that may be interesting to readers and while I'll never qualify as a journalist I can at least share some of the thoughts I jotted down. Storage for Integration of Renewables Two of the most important presentations came from Dr....

For the next two days I will be at the Solar Power 2005 conference in Washington DC. I'm currently deep in the bowls of the Hyatt and I'm finding that wireless internet (and also cell phone) coverage is spotty at best. I just finished the first session and will be posting conference notes later when I have a strong internet connection. It looks like there is about 300 people in attendance and the first session on Introduction to Solar was informative. If you happen to be reading this and you are attending the session, say Hello, It would...

Charles Morand The relationship - or lack thereof - between oil prices and the performance of alt energy stocks has been a long-time interest of mine. I discussed it last in late March when I looked at correlations between the daily returns of alt energy and fossil energy ETFs. At the time, I found that only a weak relationship existed between the two and that if someone wanted to make a thematic investment play on Peak Oil, alt energy ETFs were not an ideal way to do so.  Seeing as the popular press and countless "experts"...

Worldwater Corp (WWAT) announced that it has signed a $109,824 contract to build and install a solar electric power generation system for Quest Environmental & Engineering Services, headquartered in Clinton, New Jersey. The photovoltaic (PV) system will provide electricity for the company, and is expected to substantially reduce electrical usage costs for the facility.

SatCon Technology Corporation (SATC) nnounced the completion and delivery of the 100 kW solar inverter for the European market. The significance of this delivery is that SatCon is well positioned to participate in the largest market for solar inverters. SatCon has delivered over 17MW of commercial grade inverters over the past two years and is poised for significant growth as indicated by the pending solar projects in California on the Pacific Gas and Electric website.

Evergreen Solar Inc (ESLR) shares were down 9% on Monday after their primary supplier of raw materials pulled out of a contract. Evergreen Solar relies on granular silicon to make cells for solar panels. This silicon was supplied in part by MEMC Electronic Materials Inc. (WFR). MEMC previously agreed to supply Evergreen with 90 metric tons of granular silicon, but in January said it did not intend to ship most of the remaining balance of 53 metric tons. Evergreen plans to used its own crush chunks of silicon, but said it has not fully tested the process...

I'm going to be doing some extensive traveling this summer. While traveling I always need to power my various electronic gadgets so I can keep intouch with clients and my office. One of my trips this year is going to London and a photography tour of the English countryside. So I just ordered the Brunton Solar Port to keep all my various batteries charged. I purchased it from Amazon.com and I will do a review once I receive it in a couple days. The Brunton Solar Port 4.4 is available for purchase now at Amazon.com....

By Jeff Siegel Solar stocks are getting a thrashing today after Yingli Green Energy (NYSE: YGE) came clean about a possible bankruptcy. The stock tanked at the open and is still trading below $1.00 – down from yesterday's closing price of $1.70. Of course, the writing was on the wall with this one. Yingli's been struggling for a long time. And while I'm extremely bullish on solar, I've kept a safe distance from Yingli, as well as a lot of other China solar stocks. That being said, even the solid, revenue-generating companies not operating out of China are...

Hans Deuel at Clearfish Research presents some very good concerns about the possible manipulation of the shares of XSUNX Inc. (XSNX). I've received a number of comments about XsunX, all from the same person. I decided to look into them. They are working on transparent solar cells, have a weird history, and a weird structure. The only technological information I can find on them is all paid advertising (from IPODesktop and others) masquerading as research. Each of their press releases are misleading. They offer one key statement, and then go on about intentions. For example, the latest one...

Tom Konrad CFA Green energy experts accept that solar panels are one of the least cost effective ways to reduce your carbon footprint.  Nevertheless, many buy solar stocks.  They should rethink their investment strategies. I recently spoke on "Stock Selection in the Era of Peak Oil and Climate Change" at the ASPO 2009 International Peak Oil Conference.  Whenever green energy enthusiasts find out that I analyze green energy stocks professionally, they react in one of two ways.  Many want to know my top stock pick in general (New Flyer Industries NFI-UN.TO/NFYIF.PK) or in their favorite sector (see below.)   ...

Universal Communication Systems Inc (UCSY) announced that the company is set to make a major new investment and plans to open a new office in Los Angeles, California from which to market PV Solar Panels and PV Solar Energy Systems throughout the state. This follows the recent announcement by the State of California that it was to enact a Major Incentive Program which is the largest solar energy policy ever enacted in the United States: an 11-year, $3.2 billion incentive program aimed at spurring installation of PV Solar Panels / Systems.

Worldwater Corp (WWAT) announced the signing of contracts with homeowners in New Jersey and California to build photovoltaic solar electric systems to power their residences in parallel with their present electric utility company. The contract value of the systems in New Jersey and California is $160,540.
