So far, they haven't figured out how to turn off the sun

NPR reports:

Easy-to-install solar panels that plug into a regular outlet are getting attention just as Americans are worried about rising energy costs. That's because these plug-in or balcony solar panels start shaving off part of a homeowner's or renter's utility bill right away.

"A year ago, nobody was talking about this," says Cora Stryker, co-founder of Bright Saver, a California nonprofit group that advocates for plug-in solar. The panels are already popular in Germany, where more than 1.2 million of the small plug-in systems are registered with the German government.

For the panels to become more widely available in the U.S., state lawmakers are proposing bills that eliminate complicated utility connection agreements, which are required for larger rooftop solar installations and, most utilities say, should apply to plug-in solar too. Those agreements, along with permitting and other installation costs, can double the price of solar panels. ...

The utility companies which make a business of selling electricity don't like the promise of plug-in panels ...

"They don't want anyone messing with their business model," Stryker says. "Kicking up dust regarding safety concerns is definitely a strategy that is being used by people who don't want this for their own self-interested reasons." 

Utilities also raise potential safety issues. But they ignore that Germans have been conducting the experiment for a decade.

... with more than a million systems installed, no safety incidents have been reported for customers who used the panels as instructed, according to a research paper funded by the U.S. Department of Energy. 

... Stryker says plug-in solar took off in Germany once renters were allowed to install the systems, and she sees the potential for a similar trajectory in the United States. 

State legislation which would overcome utility company opposition is under consideration in Utah and Virginia.

Where's California in this?
