Utah Pioneered Legal Plug-in Solar

In Utah, a new law allows residents to connect small solar systems—up to 1,200 watts—directly into standard outlets. These plug-in solar systems, also called balcony solar, offer an alternative to traditional rooftop installations and require no professional setup. They generate between 200 and 1,800 watts, aiming to reduce energy costs rather than eliminate grid dependency.

Following Utah’s lead in 2025, roughly 30 other states have introduced bills to legalize similar systems. Virginia signed a law effective July 1, 2026, and Colorado and Maine approved legislation this year. California, with its high electricity costs—up almost 40% between 2022 and 2025—is poised to further expand access.

Widespread adoption in the US faces hurdles due to outdated regulations and utility concerns about grid stability and safety. While Germany has successfully integrated plug-in solar through standardized equipment and regulations, US utilities require permits and agreements even for small-scale systems. The work to update regulations and encourage wider use continues across the country.
