A KUTV story regarding plug-in solar has generated significant interest among Utahns curious about whether the technology can reduce electricity bills and if homeowners can legally install systems themselves. Although Utah became the first state in the nation to pass a law allowing plug-in solar systems in 2025, the technology has not yet seen widespread adoption due to difficulties in purchasing complete products.
The potential for cost savings with plug-in solar depends on several variables including system size, sunlight exposure, electricity prices, and a home's specific energy use. One Utah homeowner reported spending less than $800 on a three-panel system that generates estimated savings of roughly $30 per month. Another user noted their 1,200-watt system has saved about $75 since October.
While the low initial cost could allow for a faster return on investment compared to expensive rooftop solar, actual production fluctuates based on weather, shading, and seasonal changes. For example, while panels can operate efficiently in cold weather, snow coverage and shorter winter days can reduce total production.
The ability to simply plug a system into a standard outlet remains a challenge due to the lack of established safety standards. Utah Representative Ray Ward, who sponsored the state's plug-in solar law, stated his intention was to allow consumers to use these systems without needing electricians or utility approval. However, UL Solutions noted that while they have developed the UL 3700 safety standard, a technical committee has not yet been formed to review and vote on it.
Safety remains a central point of debate. UL Solutions emphasizes that certification is necessary to protect against hazards like fire and electric shock, noting differences between European and American electrical systems. Advocates argue that requiring licensed electricians would undermine the affordability and ease of use that defines plug-in solar.
For renters and apartment residents, the portability of small plug-in systems offers a potential advantage, though they must still consider sunlight access and property restrictions like leases or HOA rules. Currently, Utah law limits qualifying plug-in solar systems to a maximum capacity of 1,200 watts to keep them within state-established parameters. While advocates continue to push for faster access to the technology, consumers currently face difficulty finding complete, certified systems designed specifically for the U.S. market.
