Solar technology is getting cheaper and more efficient. That winning combination means that many of the oldest projects in the global solar fleet may be set for a facelift. Throw in sunsetting subsidies, worthless warranties and a smattering of poorly built projects, and repowering and revamping (the latter involves changes that don’t increase capacity) will be an obvious choice for many developers in the years ahead, creating a big new subsector of the global solar industry. More than 67 gigawatts of solar capacity will celebrate its twentieth birthday this decade, according to Wood Mackenzie. A large chunk of that capacity is in the European market, where solar repowering and revamping are taking off first. In the U.K. and Germany, projects lose their subsidy support once they reach 20 years of age.
