As home-charging equipment becomes cheaper, consumers are likely to seriously consider purchasing an EV. Falling prices of solar panels, and regulations like California’s requirement for solar panels on the roofs of new homes and multifamily dwellings as of 2020, will drive improvements and adoption. As subsequent state regulations are implemented that mirror California’s, residential and commercial customers are likely to explore solar installations to power their car or fleet. This will also drive a wave of retrofitting for contractors who specialize in solar or battery bank installation, as well as power supply upgrades for fast charging. This growth will present challenges as the market becomes educated. Without many electrical retrofits in the US, there may be a higher number of brownouts, surges, and the risk of fires as people overload their current electrical system while charging their car. This could lead to more home-owners associations, neighborhoods, and towns placing restrictions on what can and cannot be charged. Conversely, enterprising groups may look to band together and install solar arrays or even community chargers to help reduce individual costs or even profit from the coming EV wave.
