The price of solar panels keeps tumbling but manufacturers are finding a sweet spot after three challenging years: volume is finally making up for the price drop as demand surges. The solar panel market is expected to grow by 30 percent this year, according to Bloomberg, driven by growing investments in China and Japan. Now that solar is cheaper than fossil fuels, new markets such as India are emerging now that solar is the most affordable and least polluting option available. This is good news for Chinese manufacturers, who produce more than 75 percent of the world’s solar panels.
