The classic image of solar panels shows rows of deep-blue rectangles glinting in the sunshine, passively absorbing new energy.
What’s overlooked in that passing scene, however, is a harsh reality. Solar panels sometimes must withstand hail, snow, high winds and, of course, high temperatures from the sun – all of which can wear down their effectiveness.
To protect their internal workings – made up of layers of sealed photovoltaic cells that turn sunlight into electricity – solar panels are baked in special resin with a solution developed by ExxonMobil in the 1990s.
That baked resin formulation ultimately helps panels live through a typical 25-year working life expectancy.
That’s the dual life of these panels – a tough exterior facing the elements to protect the sophisticated and delicate heartbeat that is producing much-needed energy.
