Glass shortage threatens solar panels needed for climate fix

BEIJING (Bloomberg): The world's biggest solar power company says a shortage of glass is raising costs and delaying production of new panels, throwing a wrench in China's plans to accelerate its shift to clean power.

Prices for glass that coats photovoltaic panels have risen 71 per cent since July, and manufacturers are struggling to produce it fast enough to keep more than a week's worth of sales in inventory, according to Daiwa Capital Markets.
