Bosch to buy Ersol, galvanizing solar sector

By Michael Shields and Peter Starck

FRANKFURT (Reuters) - Robert Bosch GmbH ROBG.UL plans to buy Germany's Ersol ES6G.DE for around 1.08 billion euros ($1.67 billion) in a deal that electrified solar stocks on Monday on expectations of more bids for "green" energy groups.

Unlisted Bosch, the world's biggest automotive supplier, has agreed to buy 50.45 percent of Ersol from Ventizz Capital for 546.4 million euros and intends to make the same cash offer of 101 euros per share for the rest, Bosch and Ersol said.

The 101 euros per share price, a 63 percent premium to Ersol's closing price on Friday, is 21.4 times Ersol's projected 2009 earnings per share, according to Reuters Estimates. Ersol shares shot up to 100.85 euros by 0845 GMT.

Ersol makes solar cells at its four production plants in Germany and California, and also has a joint venture in China. Its sales leapt 25 percent to 160 million euros last year.

Bank Sal. Oppenheim said in a note to clients: "We see this as the boldest move so far in what we see as the start of a consolidation process in the solar industry."

"In particular, we see companies from mature industries such as the automotive or the semiconductor industry bringing process know-how to the solar industry," it added.

Raw materials firms could also seek more downstream exposure by snapping up companies like REC (REC.OL) or Q-Cells (QCEG.DE), it said, while utilities and power station builders may eye Solon (SOOG.DE), Centrosolar (C3OG.DE) or Aleo (AS1Gn.DE).

Growing demand and state subsidies for renewable energy have been a boon for solar companies, but the industry is reaching a crucial stage as manufacturing capacity expands and shortages of solar-grade silicon -- a key ingredient -- start to ease.
