Solar Photovoltaic

by Clean Energy Intel This year’s period of intense over-supply in the solar sector has continued to pressure solar players, leading to a recent batch of announcements of cut-backs and cost reductions. All of this may simply seem to be a continuation of the recent slew of bad news that has plagued the industry in the past few months. However, in the end, it is likely to be seen as at least one of the antidotes to the sector's troubles. Source: SolarBuzz, by permission.   The chart above from ...

Clean Energy Intel First Solar's Blythe Solar Farm under construction First Solar's (FSLR) stock price was hit hard yesterday, falling some 25%, as a result of the departure of CEO Rob Gilette. The stock has bounced today. However, the very volatile price action is simply a sign of the extreme nervousness and underlying weakness in the sector. A number or readers have questioned my stance of being uninvested in the solar sector during the recent Solyndra-related market turmoil. Since I see solar as being a significant part of the long-term clean energy solution, this does raise some contradictions. Consequently, let...

by Clean Energy Intel In a further sign of the continue supply-demand imbalance in the solar sector, weekly data from Bloomberg New Energy Finance suggests that the spot price of polysilicon, the raw material used in most solar panels, accelerated to the downside last week, falling at the fastest pace since June. Prices of solar wafers and cells also continued their decline: 'The average selling price dropped 5.8 percent on the week to Oct. 10 to $43.78 per kilogram, according to the latest results from the London-based research firm’s survey of contracts conducted from Oct. 3 to...

Garvin Jabusch Tom Konrad has kindly provided an opportunity for me to contribute a response to his recent piece “Inverter Stocks: A Value BOS Play on Solar.” I’m grateful for the opportunity because it gives me the chance to discuss these stocks and along the way to clear up some misconceptions it seems may exist regarding Green Alpha’s portfolios and our vision of the next economy. Tom wrote, for example, that “Garvin... has been making the case that the solar sell off is irrational on this blog since...

by Clean Energy Intel Following the announcement that CIGS solar start-up Solyndra had declared Chapter 11, I published an article suggesting that although this was clearly not good news, the overall solar sector in the US was still in relatively good competitive shape, with a healthy trade surplus with the rest of the world of some $1.9bn. You can read my original article here. Although competition from China is intense, particularly in low-cost module production, the US remains a strong player across the supply chain as a whole - particularly in polysilicon production and the manufacture of the...

by Clean Energy Intel Shares in JinkoSolar Holdings (JKS) fell a full 28% yesterday after the company was forced to idle its manufacturing facility in Haining following three days of protests over allegations that the facility has been polluting the local river. The difficulties relate to one of the company's wholly-owned subsidiaries, Zhejiang Jinko, and the company has now admitted that the local environmental protection authority is investigating the allegations that the company has been discharging hazardous waste into a river: "There have been reports that Zhejiang Jinko Co., Ltd. ("Zhejiang Jinko"), a wholly owned subsidiary...

Garvin Jabusch The fossil fuel apologists in the U.S. are of course relentless in their criticism of the solar energy industry. Now with the JinkoSolar (JKS) fluoride spill, though, their hypocrisy is on full display. Earlier this month, they started talking about how Solyndra's failure means the whole solar concept is flawed (it's not), and how solar doesn't work (it does) and how it's not competitive (it is). Now, JinkoSolar, having spilled fluoride into a river in Haining province, China, is the new whipping boy. The issue though...

by Clean Energy Intel Late last month, I discussed the fact that in another sign of the undervaluation in the Solar sector, the Board of Renesola (SOL) had authorized a $100m share repurchase program. On the day of the company's announcement, its stock price was down 66% on the year. You can read more detail on the original share repurchase program and the related shareholder rights program here. As a follow-up to the original announcement, Renesola has now released details of the progress that has so far been made in executing the program. The Company itself has purchased 645,424 American Depositary Shares...

by Tor Valenza a.k.a. “Solar Fred” It’s official. With the bankruptcies of Solyndra and Evergreen, two solar panel companies with unique premium solar PV technologies, the Market with a capital M hath spoken: “Solar PV manufacturers, we, the purchasers of solar PV, do hereby care more about price than any fancy innovation. Just give us the best quality panel for the lowest $/watt, thank you very much.” String ribbon doesn’t matter. Cylindrical CIGS film doesn’t matter. Even made in America doesn’t matter unless it's at a competitive price. Apparently, all the Market wants to know are the...

Garvin Jabusch Much has been made this week about the nearly contemporaneous bankruptcy filings of two American solar companies, Silicon Valley’s Solyndra and Evergreen Solar (formerly ESLR) out of Massachusetts. These two had something in common: Both made different types of photovoltaic (PV) panels and both were more expensive than average PV. These two firms did not fail because they manufactured in America, or because solar itself is untenable (on the contrary), but primarily because they were deploying advanced technology that ultimately could not find enough of a market to achieve the scale required to become profitable. It's...

Dana Blankenhorn Building Integrated Photovoltaic (BIPV)  is often in the news. There's a romance to it. Instead of having ugly solar panels on your house, your whole house could be an integrated solar system. It could use all the heat and light hitting it, from any angle, look like any other house, and pay for itself. Pythagoras Solar, an Israeli start-up, says its solar windows, cells sandwiched in glass, can both lower heating and cooling costs while they generate electricity, paying for themselves in 3-4 years. Pythagoras is private, but most publicly-traded BIPV plays are penny stocks, like...

Tom Konrad CFA With project financing and plenty of photovoltaic (PV) modules, a shortage of projects with credible off-takers seems likely to lead to further falls in module prices.  How can investors best profit from this trend? PV module prices have dropped 70% since 2008, when the financial crisis sent demand tumbling, with Chinese multicrystalline silicon module prices currently as low as $1.49 per watt, according to Bloomberg New Energy Finance's (BNEF) Solar Spot Survey.  In part, this was an example of “the Bubble giveth, and the Bubble taketh away.” For the three to four years ending in 2008,...

A Conversation with Applied Material’s Solar Head Charlie Gay by Neal Dikeman I had a chance to chat today with Dr. Charlie Gay, the President of Applied Materials' (AMAT) solar division.  You may recall, we broke the story in the blogosphere 5 years ago about Applied’s entry into solar, which was anchored with a highly touted and very aggressive strategy for turnkey large format amorphous silicon and tandem cell plants called SunFab. Charlie reminded me that when they began 5 years ago, they did so along two major thrusts:  The acquisition of Applied Films in...

John Petersen In 2009, the world produced some 13.2 billion metric tons of hydrocarbons, or about 4,200 pounds for every man, woman and child on the planet. Burning those hydrocarbons poured roughly 31.3 billion metric tons of CO2 into our atmosphere. The basic premise of alternative energy is that widespread deployments of wind turbines, solar panels and electric vehicles will slash hydrocarbon consumption, reduce CO2 emissions and give us a cleaner, greener and healthier planet. That premise, however, is fatally flawed because our planet cannot produce enough non-ferrous industrial metals to make a meaningful difference and the prices...

Tom Konrad CFA Solar installation is a low margin business with low barriers to entry, but consolidation may bring competitive advantages in some sectors of the market. I recently took a look at Principal Solar (PSWW.PK), a reverse-merger solar developer roll-up play, and found it remarkably lacking in hard data.  But there are a handful of other publicly traded pure-play solar installer/developers, as well as vertically integrated solar manufacturers like First Solar Inc (FSLR) which have been developing projects with their own panels, and solar developer-operators like Etrion Corp. (ETRXF.PK). The Shape of the Solar Installation...

By. Dr. John C.K. Daly The ongoing tragedy of Japan's Daichi Fukshima nuclear complex will prove to be a boon for renewable energy in Japan, and astute investors should begin carefully to follow Tokyo's new priorities. Before the March 11 twin disasters of a massive earthquake followed by a devastating tsunami, about 30 percent of Japan's electricity was generated by nuclear power, and Tokyo had ambitious plans to raise its market share to 50 percent over the next two decades, with renewable accounting for 20 percent, Japanese Prime Minister Naoto Kan told journalists earlier last month. ...
