For the entire idyllic visions of photo voltaic blanketing the globe, solar glinting off the glass like modernist amber waves, there’s comparatively little consideration of the ultimate resting place of those self same panels: mendacity in landfills, their energy sapped.

Essentially the most environmentally pleasant resolution, after all, is recycling them as a substitute. However alternatives are at the moment costly, restricted and depending on geography. To date, the repercussions of that minimal market are slim; panels are designed to final two or three many years, and most massive photo voltaic installations haven’t hit that age but. By 2030, nevertheless, the mass of panels reaching the top of their helpful lives will hit eight million metric tons, in line with the Worldwide Power Company.  

Which means the photo voltaic trade — if it’s to dwell as much as its sustainable bona fides — will want an economically viable resolution to cope with the tools. As time ticks in the direction of 2050, a yr when a number of international locations, utilities and U.S. states have mentioned they’ll hit net-zero emissions, photo voltaic is slated to grow to be an more and more massive portion of the electrical energy combine. And the problem of what to do with all of the defunct panels will solely develop.
