PLUS: Albuquerque deploys 6 MW of solar across city facilities in push toward 100% renewable goal

Subscribe on Substack | Visit solarcurrents.co

Good morning. Ten US states have legalized plug-in solar panels that renters and apartment dwellers can install on balconies without landlord permission. The move opens rooftop-free solar access to 44 million renting households. Utah passed the first law in May 2025, followed by Maryland, Maine, Colorado, and six others. State legislatures overrode utility and building code restrictions that kept the technology out of US markets for years, even as it became standard in Germany.

Renters can now buy a panel, plug it into a standard outlet, and offset grid power immediately. Prices should hit cost parity with European markets within months. The question is how quickly the remaining 40 states follow.

In today's Solarpunk Currents:

• Ten states legalize plug-in solar for 44 million renters
• Albuquerque deploys 6 MW across eight city facilities
• Municipal solar push toward 100% renewable operations
• Infrastructure-as-a-Service vs. public ownership models

Plug-In Solar Comes to Ten States

The Bottom Line: Ten US states have legalized plug-in solar panels that renters and apartment dwellers can set up on balconies and patios without landlord permission or permanent installation. Utah passed the first law in May 2025, followed by Maryland, Maine, Colorado, and six others. The panels connect to standard electrical outlets and send power directly into a home's circuit. This opens solar access to the 44 million US households that rent their homes.

The Story: Temporary workers, renters facing high electricity bills, and low-income households locked out of rooftop solar can now buy a panel, plug it into their kitchen outlet, and start offsetting grid power immediately. The technology has been standard in Germany and other European markets for years. US utilities and building codes blocked it until state legislatures began overriding those restrictions in 2025.

By the numbers:

• 10 states have passed plug-in solar legislation as of September 2026, according to pv magazine
• 44 million US households rent their homes and previously had no access to rooftop solar
• European plug-in solar markets are "well established," with prices expected to drop to cost parity in the US within months
• Utah became the first state to legalize portable solar devices in May 2025

What remains: Business models haven't stabilized and regulatory conflicts persist over technical standards and utility opposition. Several states are expected to pass similar laws in coming months, but the regulatory framework remains fragmented across state lines.

Albuquerque Deploys 6 MW Solar Across City Facilities

The Bottom Line: Albuquerque broke ground on 6 MW of solar across eight city facilities including animal shelters, pools, a BMX park, and the airport. The city is moving toward its 100% renewable energy goal for municipal operations. The city partnered with Sustainability Partners and Energy Systems Group to deploy rooftop and carport installations that phase in through 2027. The city makes monthly usage payments while the private company owns and maintains the infrastructure.

The Story: At the Eastside Animal Shelter groundbreaking last week, Mayor Tim Keller framed the approach as using "every tool available" to deploy solar without upfront capital costs. The installations combine power generation with covered parking at high-traffic sites like Isotopes Park and the West Mesa Aquatic Center. The airport installation includes 10 EV chargers and battery storage for backup power.

By the numbers:

• 6 MW of solar generation across eight municipal facilities, with construction phased through 2027 (Solar Power World)
• 8 facilities include the 911 Call Center, Ken Sanchez Transit Facility, Duke City BMX Park, Highland Pool, and Albuquerque International Sunport
• 10 EV chargers and battery storage deployed at the airport site for critical electrical backup

What remains: The Infrastructure as a Service model trades public ownership for faster deployment. The city pays monthly fees to a private company rather than owning the solar assets outright. Whether this serves ratepayers better than municipal bonds or utility-owned solar over the system's 25-year lifespan remains an open question.

The Quick Scribbles

Coastal solar projects face costly corrosion damage from salt air when systems lack proper protective engineering. Asset owners need specialized materials and coatings designed for marine environments to avoid premature equipment failure.
