New York Times: Until very recently, the solar industry was mainly concerned with getting a toehold in the production of electricity at a utility-level scale. Now a New Jersey company is looking for its niche in a different fieldhow to handle a system that is saturated with solar energy, sometimes enough to destabilize the electric grid. The company, Petra Solar, has a highly visible product: It is under contract to supply 200 000 panels that Public Service Electric and Gas will attach to utility poles around New Jersey. Around 75 000 are already up. Matthew L. Wald, writing for the New York Times, describes the panels’ design and their “smart” functions.
