Should homeowners and renters be legally permitted to install plug-in solar arrays?

Pennsylvania Representative Chris Pielli has introduced House Bill 1971 to authorize the use of plug-in solar energy systems. The legislation aims to reduce consumer power costs and expand energy access for residents, including renters who cannot install traditional rooftop solar arrays.

Why it matters

The proposal seeks to provide residents with lower-cost energy alternatives and eliminate bureaucratic hurdles for homeowners and renters. It addresses the growing burden of electricity rates by allowing consumers to adopt safety-certified technology that integrates directly with home outlets.

The proposed bill sets a 1,200-watt limit for individual plug-in solar units, which typically cost between $300 and $2,000. Each panel can generate approximately 270 kWh annually, potentially covering 10 to 30 percent of a home's energy usage.

The players

Chris Pielli

He is a representative in the Pennsylvania legislature who introduced House Bill 1971 to address solar energy accessibility.

Underwriters Laboratories

This global safety science organization released the UL3700 framework to establish standards for the safe operation of plug-in solar energy systems.

The details

These systems connect to standard outlets via a microinverter that directs power into the home. The legislation would prohibit electricity distributors from charging extra fees to customers who utilize systems that comply with the Underwriters Laboratories UL3700 safety framework.

January 2026: Underwriters Laboratories released the UL3700 safety framework.
August 2026: A UL-compliant microconverter that shuts off during outages reached the market.
December 2026: The Pennsylvania legislative session is scheduled to conclude.

Market Landscape

This move aligns Pennsylvania with at least 10 other states, including Utah, which legalized the technology in 2025. It also mirrors widespread adoption seen in Germany, where over 1 million systems were installed between 2022 and 2025.

Consumers could potentially save money on electricity bills as rates are expected to increase in 2027. The bill aims to provide an affordable solar option compared to traditional rooftop arrays, which can cost up to $22,400.

The takeaway

Plug-in solar technology offers a more accessible alternative to expensive rooftop installations for homeowners and renters alike. Residents should monitor the legislative process to see if these systems become a permitted tool for managing rising household energy costs.

What happens next

Representative Pielli plans to reintroduce the legislation in the next session if the bill fails to pass by the end of the current session in December 2026.
