A new study shows size matters in solar energy. The first ever life-cycle analysis comparing big and small solar photovoltaic systems has concluded that small-scale solar systems are in fact better for the environment than even the largest, and most efficient, solar farm.
Historically, solar electric systems were so expensive that many felt they could not pay for themselves. Today’s reality could not be more different with renewables now the cheapest form of energy in the global mix. Not only that, solar panels can now easily repay the energy invested in their production many times over.
