The solar industry faces a critical challenge due to its dependence on silver, a costly and difficult-to-source metal essential for most solar panels. Although copper-based panels have demonstrated ...

New research has uncovered a critical challenge in solar energy with the discovery that a considerable number of solar panels degrade much more rapidly than expected. About a fifth of solar panels ...

Around a fifth of solar panels examined in a new study fail much faster than expected and some may last for only half their anticipated lifetime. Graph showing the long tail problem of PV degradation ...

For years, solar power at home was mostly limited to people who owned their rooftops and could afford the steep upfront costs. But now, a new generation of small, affordable systems — often called ...

In his new book, Here Comes The Sun, author and activist Bill McKibben argues that we’re at a tipping point where solar and wind power is now cheaper to build and harness than fossil fuels. Because of ...
