California is requiring solar panels on all new houses: here’s what that means - The Verge

Later in the article: "Though buyers could see their monthly mortgage go up by $40, their utility bills would fall by $80. Over time, a family would save $19,000 of today’s dollars, adjusted for inflation, over 30 years, according to Beck."

"California has become the first state to require that new homes be built with solar panels. The rules go into place in 2020 and are part of the state’s ambitious efforts to cut greenhouse gas emissions. But these requirements also make it more expensive to build in a state where housing is already extremely expensive.

The new building rules approved by the California Energy Commission apply to all residential buildings up to three stories high (including both single-family buildings and condos). They’ll no doubt help California reach its goal of having at least half of electricity come from renewable energy by 2030. Solar is already responsible for about 16 percent of California electricity."
