It seems obvious that investing in renewable solar energy saves money for those who install photovoltaic (PV) systems for their homes. However, what might not be so obvious is that PV systems also reduce electricity prices for all those with no solar panels, as professor Robert Kaufmann from Boston University discovered. His research revealed that the approximately 40,000 households and community groups with solar panels in Massachusetts reduce electricity prices for all of the three million electricity ratepayers in the state, including those with no solar panels.
“Until now, people have focused on how much was being saved by those who owned PV,” says Kaufmann. “What this analysis quantified was that it actually generates savings for everybody.”
