Background
A South Bay homeowner reached out to Xero Solar with the goal of reducing their annual Southern California Edison power bill. They were concerned that if they didn’t act now, their utility bills would only continue to rise over the coming years.
And they were correct. SCE has increased their rates by an average of 14% year-over-year and by 48% overall in four years. With the current trends in rates, the savings and payback period will only improve.
