A rough 2011 in solar energy could leave only the strong to survive.

As a phenomenal first half of 2010 winds to an end for the solar industry, it's time we take a look at the landscape heading into a competitive second half of the year and 2011. With feed-in tariff cuts on the way and massive capacity building in the industry, many an analyst has voiced concerns for solar in coming years. So let's take a look at where the major manufacturers stand from a strategic and competitive standpoint.

There are three major factors I watch in solar: cost per watt, efficiency, and gross margin. Obviously, lower cost per watt is good as is higher efficiency. Gross margin tells us how those two numbers drive through to a selling price and therefore profit. Below, I have a chart of five of the major module manufacturers and my three key numbers.

Trina Solar (NYSE: TSL)

Solarfun (Nasdaq: SOLF)

$1.31 (external wafers)



SunPower (Nasdaq: SPWRA)

As usual, First Solar wins lowest cost per watt but also has the lowest efficiency. Trina Solar and Yingli are well ahead of crystalline competitor SunPower on cost but can't quite match up on efficiency. As competitors JA Solar (Nasdaq: JASO) and LDK Solar (NYSE: LDK) build up module plants, the slight differences in these competitors' cost structures will be expanded in the fight for customers.

Thin film -- First Solar
It's no secret First Solar is the most price sensitive module manufacturer. Last year, it announced discounts in the German market when silicon prices started to fall. Its low-efficiency panels have to be less expensive per watt to compensate for the higher land and development costs associated with installing its panels. Where First Solar stands above the rest and remains in the strongest position is the gross margin it achieves on low-cost panels. This gives First Solar flexibility when competitors try to undercut prices.

Crystalline silicon
Crystalline silicon solar modules have been rapidly coming down in price. Trina Solar has seen its module costs fall from $1.67 a year ago to $1.10 this quarter. This was due not only to lower silicon spot prices, but also more efficient use of silicon in its cells.

As costs have fallen, crystalline module producers have added capacity, leading to potentially more fierce competition if 2011 is as weak as some expect. Unless manufacturers can create captive demand from their own power plant developments, the only way to drum up demand will be to lower costs, leading to a price war.

Cost limits of silicon
The elephant in the room is the limited ability of silicon prices to decline. As silicon prices have fallen, crystalline silicon panel manufacturers have benefited. In the last year alone, Trina Solar reported silicon price per watt had fallen from $0.84 to $0.36, which helped module costs fall 34% in a year. But silicon can't fall to $0, so cost reductions have to come from somewhere else in coming years. Trina Solar's non-silicon cost reduction hasn't even kept pace with First Solar's overall module cost reductions. See the chart below.

This trend is true across crystalline silicon manufacturers. Unless it can find ways to cut costs beyond falling silicon costs, First Solar may take a wider lead in the cost battle.

Final word
In solar, it's apparent to me two things will drive results over the next few years: low cost of production per watt and the ability to create captive demand (project development) when external demand isn't there.

In my analysis, First Solar is in the strongest strategic position heading into 2011. A strong balance sheet, low costs, and a big development pipeline should cushion it through the year. After that, Trina Solar and Yingli Solar place a close second because of superior cost and better gross margins than Solarfun. I also think these three companies can break into the residential and commercial market where SunPower currently gets 50% of its sales.
