I think everyone can agree that solar company stocks have been volatile. There seems to be lots of disagreement on their current valuation. Some people see the stocks as having run up too much, over-bought and expensive, suggesting they should decline back to reasonable levels. Others see the stocks as cheap and are just getting started on major up moves.

All of these companies produce basically the same product. The product converts sunlight into electricity. Some of the companies use basic semi-conductor manufacturing processes to turn polysilicon into photo-electric cells. Other companies use more exotic (different) processes to make cells out of thin films.

This chart (click to enlarge) shows us that all of the solar companies are growing rapidly. They are selling at high multiples of trailing earnings, but low multiples of future expected earnings. Many of the companies reported great growth in revenue and earnings in their last quarterly reports, beating analyst expectations. I like the trend.

On my web site I did a review of solar cell manufacturers, comparing their 2007 production of 3.8 GW of power producing capacity with world energy consumption. This is a trivial amount of capacity. They could produce over 10 GW in 2008 and still be only a tiny fraction of world new installed capacity. As long a countries like Germany, Spain and the United States continue to subsidize new solar systems, there seems to be plenty of demand that can't all be met for several years at least.

I like solar stocks as an investment in alternative energy and believe the future for these companies to be bright! I think the government incentive programs will continue and these stocks are cheap based on possible double or triple digit future growth. I especially like the stocks trading at low forward P/E ratios and low 5 year expected PEGs.

Disclosure: I have long positions in CSIQ and TSL.

    Are you sure your currency is correct for SOLF (lmao)! Don't publish P/E's without knowing the currency !

    Everyone knows TSL has the lowest P/E's and your SOLF FPE is misleading - with intention ?

    May 24 02:16 PM
    The earnings and sales for SOLF have to be converted. One Chinese Yuan equals 14.4068 US cents. Or, One US Dollar equals 6.9416 Yuan.
    So, The 8.19 earnings is actually $1.16 for 2009 and the PE isn't 3 it's 19. Yahoo lists SOLF in Yuan & everyone else in USD. Check Reuters.

    Solar is not driven purely by economic forces. There is a whole subsidy angle; not to mention local angle. Utilities will buy more solar products from local manufacturers and they will only convert to solar grid if their local govts. will subsidize.

    I do not think P/E or any other multiple will reflect this complication. It also means there will never be a monopoly in solar industry which might be a good thing.

    Seems to me you left out the best one ...check the FPE on YGE
    SOLF has a small market cap and that is why I am pessimistic at the current price....all had huge run except YGE...that is why they may be the safest bet and news just out should help propel it ( manuf silic )

    ESLR won last week $1 BILLION contracts and have 1.85B backlog.
    ESLR IS THE NEXT HERE TO RUN !!!
    they have to change the table and to calculate ESLR contract, things will be much different.
    ESLR NEXT $18
  •  
    May 24 10:04 PM
    I agree totally with you sha6852 regarding ESLR! ESLR will definitely start receiving upgrades and updated price targets. $18.00 is certainly reasonable given that they just doubled their sales for the next 4 years!
  •  
    May 25 04:08 AM
    If you like ESLR then be careful. Goldman Sacks could cut the price target like they did with SOLF. Short interest in ESLR is about the same as SOLF.

    IMO

    STP = a China play AND a solar play all wrapped up in one profitable company. Energy is China's critical success factor, STP is a Chinese company. The Chinese are NOT stupid - like the U.S. politicians - the Chinese WILL use their own domestic company to fill their cast solar energy needs. STP has a place at the head of the table of the boutnious Chinese energy market.

    ALSO agree with ESLR comments. This company will soon acheive profitability, and their connections and activity in SPain and Germany will werve them well as a profitable large global solar provider.

    STP and ESLR will be the solar IBM''s of the immediate future. Both are cheap, both also leverage off the high price of oil and the current political environment.

    Buy on dips, trade on bubbles, and hold hold hold core long terms positions in both stocks and IMO yo'll be looking at $200 to $400 stock valuations over the next 5 to 10 year period.
  •  
    May 25 11:51 AM
    PS

    While no one will be allowed to takeover STP = the Chinese are not stupid as our American politicians are.

    ESLR is a potential takeover candidate as well. Fo instance GE does not currently have a solar component in its business portfolio, GE does have a wind component and a nuclear component in its business portfolio.

    So with STP you get a China play (for free)
    AND with ESLR you also get a potential takeover candidate = soon as they acheive profitability (next 1-2 years)

    IMO

    May 25 11:56 AM
    I like ESLR particularly for its proprietary tech. for making more from less. $18 is a short term target. $28 is more acceptable.

    Remember the polysilicon shortage a few years back? Its here again, ESLR will reap the benefit more than FSLR simply on a relative basis.

    Some thoughts.

    The comment that "everyone knows TSL has the lowest PE" may have been based on my articles when TSL was at $41. Now that CSIQ has fallen from the $40's to the $30's, and now that TSL has gone up from $41 where I recommended it to $48, I think the FPE's on these two companies for 2008 are comparable at about 15.

    I think it is folly to use 2009 FPE's when the second quarter of 2008 hasn't even been reported. Too many things can change in 18 months (yes susbidies, no subsidies, ASP's, price of poly, etc).

    However, CSIQ has run hard due to its recent blowout quarter, but TSL hasn't yet reported. Assuming the delay in reporting is not indicative of a problem with earnings (and my guess is, it is not), I think TSL has the better chance of running once it does report, although I think the overall DOW may be in for a rough week this week. I plan to buy more TSL if it can be bought at $45 and CSIQ if I can get it at $35.

    As to ESLR--yes, the two big orders certainly put this company on the map, but we have no knowledge as to the pricing of the orders, the likely execution by this company, and hence, we have no idea what its net profit margins will be.

    So this one is still very speculative in my book. Everyone had great hopes for AKNS a year ago, and what has its price done?

    Finally, as to STP--although it surprised this quarter, it also hasn't done much in the past few months, price-wise. Its 2008 PE is close to 30, and I simply see no reason it deserves a PE twice as large as either TSL or CSIQ.

    As to YGE, I calculate its PE to be greater than 20, and again, no greater compelling value than TSL/CSIQ.

    Final note: The solars have run nicely during solar earnings season, so do NOT be shocked if they slide back and consolidate, especially if the markets retest their March lows. Also, these stocks are EXTREMELY volatile (sometimes for good reasons, often not) and if you can't handle that, this is not the space for you.

    Conclusion: Although there is some risk of downside moves, to me, TSL and CSIQ, at $45 and $35, offer the most compelling values in the solar space today.

    Jack, TSL's management said they will be reporting the end of May or the beginning of June, since they reported on March 4th 2008, this makes sence.

    This was one of the more helpful articles on solar stocks that I have read in recent time. The table is especially useful in that it gives pretty clear direction of the revenue & earnings streams of some of these companies. Nice job.

    You can call it redneck arrogance but I don't trust pure China plays. The bottom line is there is no transparency to these companies.

    ESLR is a bargain ay any price below $16 until they bring their new manufacturing facilities to 100% capacity.

    FSLR, Suntech, and most other solars are grossly over priced. All the talk about FPE is humorous and tragic. The market has not been driven by fundamentals for over 10 years. There is way too much stupid money in the market for fundamentals to matter.

    The analysts are no help either. They are driven by a desire to for 15 minutes of fame and rarely have a clue what makes the market move. Consider the recent roller coaster market. One day the market moves down. The analysts proclaim it is due to oil futures hitting $118. The very next day the market posts a very nice gain and the analysts proclaim it is due to oil futures hitting $121. The analysts need to do the world a favor and put away their magic eight balls.

    The dirty little secret of the market is that only a privileged few have access to true market momentum data. Until the exchanged are forced to publish this data free of charge, the real strength or weakness of equities prices will remain hidden to the masses and the stupid money will continue to flow into the pockets of those that are in the know.

    Dear Bubba,

    Agree FSLR is overpriced, but I would be fascinated to learn how you arrived at a fair price of $16 for ESLR.

    As to the "stupid" money--that was much more true 2 months ago than it is now. What I have seen is that the low PE stocks (CSIQ, SOL, SOLF) have run and the high PE stocks (FSLR, SPWR and STP) have not. Seems to me the "stupid" money is getting smarter.

    TSL hasn't moved as much because it hasn't reported. I expect good things from TSL.

    Jack, one problem with your articles is, you don't look into TSL's guidence. TSL has guided for more than 4 EPS 2008 and I bet it will be more than 5, and the 2009 EPS is sure 8-10 US$. So, leave these actual to low estimates aside, and you will see that TSL is half the price of CSIQ.
  •  
    May 25 09:43 PM
    Larsson, please refer me to where TSL has guided to $4+ for 2008. As to your being "sure" it will be $8 to $10 in 2009, I would really like to know where you got that one.

    I have made my methodology clear--I use consensus which I find on Schwab Earnings Reports, for all companies. My own analysis calls for $4.50 on TSL in 2008, and $2.75 on CSIQ. I do not project 2009 because I believe that is witchcraft--waay too many unknowns.

    Using my own estimates rather than the consensus does yield a lower PE for TSL than CSIQ. However, I will only be comfortable with my $4.50 estimate once TSL announces.

    Jack,

    Over the last several months I've purchased roughly equal amounts of CSIQ, TSL, JASO and YGE. Combined, they account for about 5% of my portfolio. I'm willing to ride out the volitility and see how things play out in the next few years. Any thoughts?
    Would you suggest adding SOL or SOLF?

    Thanks!

    O.K. Jack understand, in Q4 2007 TSL guided the year 2008, margins & Sales and you can estimate 2008 EPS. Looking to the currency (EURO) Impact, the 4 US$ should move to EPS 5US$ and higher, ASP rises with the high EURO. Consider this too. Considerin this + own TSL guidance, we are now trading on P/E 9-10. The latest estimations for TSL are av. 4.1 EPS 2008 and still way too low as not considering currency.Anyhow Jack, you have predicted CISQ and now you predict TSL, you are the No. 1 here in Solar, respect!

    Hi Jack,

    As always I agree with you on most things...But that STP doesn't deserve a higher valuation than the likes of CSIQ or TSL is in my opinion not true...the company is the greatest producer of solar panels(overtook Q-cells and I think Sharp)....and I think that size is ,and will be, quiet important in the coming years when it comes to lowering ASP's...(bargaining power, faster learning etc.)...does it justify twice the PE of CSIQ or TSL no probably not but what does it mean?Does it mean that STP is overpriced or that the other two are underpriced?My guess is the latter, these companies are trading at levels that Blue chips usually trade at(but with earnings/revenue growth very much unlike Blue chips)...I think STP will break out in the near-term....at the latest when they will announce a hugh poly deal that is rumored to happen soon....$1 Bil. in short term cash flow certainly speak for that scenario....

    Also i started building a CSIQ position, again, but quiet slow....jumped in @$38 and now waiting either for lower prices (gap close)...or just earn some money either way I am quiet comfortable with the investment at that price in the short term(less than 1 year)....with kind regards from across the pond CW

    Long ABX, CSIQ, STP, TSL

    PS this week in Germany they are meeting to discuss the future of incentives...(EEG)We'l... see what happens there...if anything unexpected happens I would get myself ready for the solar stocks getting pummeled...but nothing extraordinary is expected but who knows....

    CSIQ look prety good in 2009, they will produces 400mw module, and about 100 to 150mw specialty product. So It will outbid TSL, however TSL might expand from current capacity.

    I am long long with TSL, and CSIQ just now.

    May 26 07:48 PM
    According to a person I met this week, who works for a solar related company, investors are ignoring the potential market for solar in China and India. What he said, is that, most people in China live in rural areas, with virtually no electric grid infrastructure. Off the grid solar electricity makes perfect sense for these parts of China. He said this will be a revolution, not unlike our own rural electrification projects of the 1930s, like the TVA, except solar and other alternative energy will be the focus. We tend to think of the markets for Chinese solar companies as limited to exports to Spain, Portugal etc, while ignoring the vast needs of a growing China, with 1.3 billion people, 3/4 of whom live in these rural areas. This is something I have wondered about, without knowing these demographic numbers. This is a good reason to ignore pundits who predict an oversupply of solar panels. They may be right in the short term, but anyone with foresight should see that the potential for solar is still huge, probably bigger than we imagine.
  •  
    May 27 12:56 AM
    frflyer, I agree that China and India are two pretty big potential markets but the fact remains that the cost of these solar projects remains largely out what the companies and people in these two countries are able to and willing to pay. The initial costs in addition to maintenance costs are too much for many to handle.

    I know a relative in China that is pretty well off himself. He had install a complete solar system for his home 2 years ago that met all his electricity needs. The system broke down half a year ago, and he decided it wasn't worth the hassle and the money to repair it.

    Don't get me wrong, I believe in the future for the solar industry and have encouraged many friends and family to look into the whole industry as a investment, but it remains to be see if China, India, Brazil, etc could become big markets for solar.

    May 27 09:10 AM
    I see a huge future for solar with strong demand extending into the distant future. Capacity trends are more difficult to judge, but I can't see an excess for the next few years at least. Increasingly, builders will be required to "go green", and subsidies are likely to persist beyond the point where technological advances in solar eliminate the need for subsidies. TSL is my largest position now, followed by YGE and SOL. Closed out a large stake in SOLF on its explosive upmove and sold most of CSIQ on its breakout move. While the long-term outlook for these stocks seems bright, their volatility also makes them ideal trading stocks. I also hold some SPWR indirectly through a stake in less risky CY, the majority owner of SPWR.

    The STP announcement today with Shunda cements their position as one of the top solar names. The capital raised from their convert has been put to work flawlessly. This should boost STP's poly supply to 800MW in 09. They are subject to price changes in 08, but starting in 09 they seem very stable. Very reliant on Spain, though. Great company!

    Update on SOLF - The Earnings projection for SOLF in my chart is apparently incorrect. Newstar - appreciate your pointing it out. I posted the projected 2009 earnings number after checking with a couple of sources. Today one of my sources has reduced the number to $1.34. Newstar got a $1.16 number. At $1.34 the 2009 P/E would be 15. Remember these are estimates. I don't trust the 5 year growth estimate for SOLF, but the PEG would be higher than the 1.03 number listed in the chart. SOLF is a stock that doesn't have as good a visibility as the other solar stocks and as such I consider it to be very high risk. Sorry for the incorrect data.

    May 29 02:05 AM
    Regarding comments on solar in India, I must say that companies that deal with solar panels or PV cells will only purchase to resell or export. I don't think that solar will make much of an impact in India domestically. Electricity is not that very expensive although relatively to salaries it might be. The problem is that there is no reliability in getting power continuously. Power cuts and power shutdowns are common in almost all major cities including Bangalore, the software capital. Most companies use generators which probably run on diesel and is cheaper than petrol (gasolene). the only way that solar might pick up in India is if companies and industries begin to install solar panels. Other than that I don't see India as a major player.

    The table above has a huge error in reflecting Solar Fun's (SOLF) earnings. The 2009 estimate of 8.15 is in RMB's not U.S. dollars, thus exaggerating the earnings by about 6 times. The est. P/E is therefore not 3, but more like 18. I hope the writer, Ryden, checks this and comments. Yahoo made the same mistake.
