New Jersey now allows the sale and use of portable solar panels under 1,200 watts without utility approval or metering, enabling residents to save up to $50 monthly on electric bills. These plug-in units, often used on balconies, cost between a few hundred dollars and $1,500. The law also prevents landlords, homeowner associations, and municipalities from banning or requiring permits for these panels, offering a simpler alternative to rooftop solar.
