NEW YORK (

TheStreet

) -- Cloudy skies? An overcast future? Sure, there are plenty of cute solar-ish metaphors one can use to describe the downgrade

First Solar

(FSLR) - Get Report

received this morning.

But, ultimately, the facts are simple: On Monday, analysts from

Soleil Securities

dropped the thin-film module manufacturer to sell from hold and cleaved the price target to $96 from $170.

According to a report from

Barron's

, Soleil analyst Paul Leming cited over-capacity and dipping solar-module pricing as chief concerns, despite the manufacturer's current success in the thin-film market. Consequently, earnings-per-share estimates this year were pulled down to $6.80 from $8.10, while 2010 forecasts were moved to $5.65 from $8.25.

"While we believe FSLR will remain the low-cost producer of a solar module over the next several years, the company is facing a much more difficult margin environment going forward and it is now done with the high-growth portion of its capacity ramp," Leming wrote in a note, according to

Barron's

.

Citing overcapacity in the polysilicon industry, Leming also added that "what appears to be less widely recognized is that all of the solar value chain -- wafers, cells and modules -- are going to be wrestling with too much capacity for the next several years," according to

Barron's

.

First Solar shares were bidding at $131.95, down $4.80 or 3.5%, on Monday morning.

Other solar shares were moving lower in morning trading as well.

Suntech Power

(STP)

,

SunPower

( SPWRA) and

Yingli Green Energy

(YGE)

were losing 1.8%, 2.6% and 1.1% each.

LDK Solar

(LDK)

and

Trina Solar

(TSL)

were tracking in the red as well, down 3.1% and 0.2%, respectively.
