Top 10 Solar Companies To Watch In Right Now

The University of Delaware is testing the use of electric vehicles as energy storage devices, long the dream of the wind, solar, and battery industries. There are both opportunities and challenges with such a system.�

Owners of a Tesla (NASDAQ: TSLA  ) Model S or a Ford (NYSE: F  ) Focus Electric could generate income from their vehicles just for use of the battery. In turn, the grid could become more efficient and cost-effective, with EVs to balance out load.�

But would car owners like burning their batteries more quickly? And right now Ford and General Motors (NYSE: GM  ) don't make vehicles that could store much energy and still have enough to drive any reasonable distance.�

Advisors' Opinion:

• [By Travis Hoium]

  The largest manufacturer in China, Yingli Green Energy (NYSE: YGE  ) , expects similar trends in the first quarter, with shipments falling 6% to 7% and gross margin between 4% and 4.2%. So, every company follows the same general trends on both the top and bottom lines.

• [By Travis Hoium]

  Who will win the solar panel battle?
  Installers, particularly those in residential, deal with this conundrum every day, and the industry is changing rapidly. SolarCity (NASDAQ: SCTY  ) has been known to use manufacturers like Trina Solar (NYSE: TSL  ) and Yingli Green Energy (NYSE: YGE  ) , who are two of the biggest manufacturers in the world and compete mostly on cost. Where system costs are low, they will win business.

  What: After a two-day run-up in solar stocks, the party ended quickly, and every stock in the industry is dropping like a rock. Suntech Power (NYSE: STP  ) led the declines by falling 23%, and LDK Solar (NYSE: LDK  ) , Yingli Green Energy (NYSE: YGE  ) , and JA Solar (NASDAQ: JASO  ) all dropped at least 15%.

Trina Solar's Honey technology can reach 19.6% efficiency. Then there's the efficiency leader, SunPower (NASDAQ: SPWR  ) , whose Maxeon cells can be 24% efficient, creating a 21.5% efficient production module.

• [By Gary Bourgeault]

  Other companies of note that will be hurt will be LDK Solar (LDK), Suntech Power (STP), JA Solar Holdings Co., Ltd. (JASO) and Renesola (SOL) among others. Some these are already hanging on by a thread because of taking on too much debt and defaulting on bonds.

Advisors' Opinion:

• [By Robert Rapier]

  The solar PV sector is likely to outperform the market averages over the next decade. However, it can be hard to find fair value in this hot sector, so it certainly helps to buy on extreme weakness when volatility and fear strike. For example, on Aug. 28 we recommended First Solar (Nasdaq: FSLR) to The Energy Strategist subscribers. Last month, we urged the same subscribers to take some money off the table after a gain of more than 80 percent. At the moment I see no real bargains in the sector, but First Solar is one that I would add on a significant correction. Over the long haul the solar PV sector looks like a big winner, but you need to be selective with your entry points. �

• [By Whitney Kisling]

  Gains were led by stocks that had fallen in 2013. First Solar Inc. (FSLR), the Tempe, Arizona-based power technology developer, has jumped 38 percent since sliding 13 percent in the first quarter. Cliffs Natural Resources Inc. (CLF), the Cleveland-based iron-ore mining company, rallied 8.8 percent on April 9, its biggest increase since September. The shares were down 52 percent for 2013 before last week.

  Answer: First Solar Inc (NSDQ: FSLR) is definitely on our radar. It makes absolute sense to include in the Utility Technology section of the UF How They Rate table.

• [By Doug Ehrman]

  Solar flares
  The second week of April saw solar companies explode to the upside, driven largely by bullish comments from First Solar (NASDAQ: FSLR  ) about the company's outlook for the rest of the year through 2015. The company also announced its acquisition of TetraSun under undisclosed financial terms. TetraSun brings expertise with silicon photovoltaic technology that's been used by other leaders in the field. The acquisition should open up new avenues for First Solar and give the company the ability to improve overall efficiency.

Advisors' Opinion:

• [By Travis Hoium]

  China continues to prop up solar
  Suntech Power and LDK Solar (NYSE: LDK  ) have both defaulted on loans, but that doesn't appear to be a clear sign that China is willing to let its solar industry consolidate. These two companies along with countless others would be bankrupt in the U.S. or Europe but investments from state-owned entities and loans from state-owned banks have propped up the entire industry.

• [By Bryan Murphy]

  Three weeks ago, I recommended Real Goods Solar, Inc. (NASDAQ:RSOL) as a buy. Though the stock was still drifting in the shadow of a huge May pullback - from a high of $7.17 to a low of $2.13 by mid-June - RSOL was finding some support at key moving average lines, and even pushing up and off of them. Not many of you (and I'm using "you" interchangeably with "investors in general") seemed to care. So why am I looking at Real Goods Solar again now? Because, with competitors LDK Solar Co., Ltd (NYSE:LDK) and ReneSola Ltd. (NYSE:SOL) seeing their shares surge today, odds are good RSOL is going to get swept up in that move. Real Goods Solar shares are a better bet, however, in that - unlike SOL and LDK - they aren't overbought yet.

• [By Travis Hoium]

  This is a big hit for the Chinese solar industry and some of the biggest players in solar. Earlier this month, The Wall Street Journal reported that Europe was poised to put a 48.6% tariff on Suntech Power's (NYSE: STP  ) �panels, 55.9% on LDK Solar's (NYSE: LDK  ) , and 51.5% on Trina Solar's. Companies who cooperated with the investigation on dumping would be slapped with a 47.6% tariff and those who didn't would be taxed at 67.9%. �

  Lights out, China
  China may have its fair share of struggles -- which has caused its strong economy to back off its 30-year average growth rate of 10% -- but when push comes to shove, plenty of investors are still paying close attention to multinational companies making investments in China. However, if there were one sector with a gigantic "beware" stamp attached to it, it would be Chinese solar panel producers like Hanwha SolarOne (NASDAQ: HSOL  ) .

Advisors' Opinion:

• [By Travis Hoium]

  There will be winners, though. Shares of polysilicon maker Renewable Energy fell 7% in trading immediately after the announcement because the company will likely see either lower prices or lower demand. But shares of GCL Poly, who manufactures in China and is the biggest polysilicon maker in the world, jumped 4% on Friday after the news was announced.�Renesola� (NYSE: SOL  ) and LDK Solar� (NYSE: LDK  ) also have lots of unused polysilicon capacity that will likely experience more demand because of the move. The question is if they have sufficient quality to supply the industry.

Advisors' Opinion:

• [By Bryan Murphy]

  Last Thursday when I suggested American Community (OTCMKTS:ACYD) was a stock that should be shed immediately, and replaced with a position in Real Goods Solar, Inc. (NASDAQ:RSOL), I didn't win a lot of friends. After all, ACYD was the market's newest darling, in the middle of a red-hot runup, while RSOL was "just another solar name" that happened to be lucky enough to stumble its way above a key support line. Well, I hate to be the one to day I told you so, but, I told you so. American Community shares are down 35% since then, while Real Goods Solar shares are up 36% in the meantime. Both stocks seem pretty well entrenched in their current trends too.

  Just when the Chinese solar industry is starting to gain some traction the scandals that crushed investor confidence in Chinese stocks are back again.

• [By Travis Hoium]

  In China, Canadian Solar (NASDAQ: CSIQ  ) is doing a better job transitioning to Japan and project development than most, and it would be a much better pick than most. But still, there are risks, and this Fool's choice is to stick with high-quality U.S. companies for which you don't have to depend on government banks for survival.�
