Some companies are dropping parts of their business to narrow their focus. Take Conergy, which earlier this month sold off its solar-thermal business to Zen International and partners. The company, which had been a proponent of so-called "integration," or combining various businesses, expanded its solar-thermal interests last year. But it suffered from plunging shares when it lowered its outlook in October, lost its CEO Hans-Martin RĂ¼ter when he stepped down in November and then disappointed again in February when it posted a net loss for 2007.
Meanwhile, EnerWorks launched a new solar-thermal commercial and industrial division, TrendSetter Solar Products said it was increasing importation of its solar hot-water collectors into the United States and Carnegie Corp. announced it had acquired new solar-thermal technology from its chairman Alan Burns.
