Five years after the Obama administration's renewable energy initiative touched off a building boom of large-scale solar power plants across the desert Southwest, the pace of development has slowed to a crawl, with a number of companies going out of business and major projects canceled for lack of financing.
Of the 365 federal solar applications since 2009, just 20 plants are on track to be built. Only three large-scale solar facilities have gone online, two in California and one in Nevada. The first auction of public land for solar developers, an event once highly anticipated by federal planners, failed to draw a single bid last fall.
Several factors are responsible, industry analysts say. The tight economy has made financing difficult to obtain, and the federal government has not said whether it will continue to offer tax credits of the size that brought a rush of interest in large-scale solar five years ago.
"I would say we are in an assessment period," said Amit Ronen, director of the George Washington University Solar Institute. "Nobody's going to break ground on any big new solar projects right now — utilities want to see how farms coming online this year fit into the grid, and developers are waiting for more certainty about state policies and federal tax credits."
Mersenís new HP10J photovoltaic fuse line provides superior overcurrent protection at the re-combiner box and inverter levels and covers applications ranging from 70A to 400A, 1000VDC. The enhanced fuse construction of the HelioProtection series makes it ideal for continuous temperature and current cycling withstand adding to system longevity. Low minimum breaking capacity capabilities of 1.35 times the fuse-rated current value allows for safe circuit interruption under typical low-fault current conditions produced by PV arrays.
