As small business owners seek sustainable solutions to rising energy costs and reliability concerns, the surge in rooftop solar in Puerto Rico presents a compelling opportunity. With a notable increase in installations, rooftop solar has entered the spotlight as a viable energy source, transforming the landscape for local businesses.
By the end of 2025, rooftop solar capacity reached 1,456 megawatts (MW), constituting 20% of Puerto Rico’s total energy mix. This rapid growth isn’t just a trend; between 2016 and 2025, rooftop solar installations accounted for a remarkable 81% of the new generating capacity in the region. It’s now the second-largest source of power, following petroleum liquids.
For small business owners, adopting rooftop solar can deliver significant benefits. Given the island’s history of electricity outages, investing in solar not only helps secure energy independence but also provides potential cost savings. Businesses are increasingly installing rooftop solar systems—an average of 3,850 new systems were put in place monthly in 2025, bringing the total to nearly 192,000 systems across industries.
Battery storage systems, which complement rooftop solar, have also seen substantial growth. By the end of 2025, 171,372 households and businesses were equipped with battery storage systems. These systems provide a collective energy capacity of 2,864 megawatthours, enhancing resilience against power disruptions.
Puerto Rico offers favorable net metering policies established in 2007 that allow solar owners to sell excess electricity back to the grid. This program incentivizes investment in solar technologies by allowing businesses to recoup costs by turning idle energy into revenue. In addition, the recent expansion of LUMA’s Customer Battery Energy Sharing program enables battery owners to contribute stored energy back to the grid, particularly during anticipated supply shortages.
"These advancements position rooftop solar and battery storage as not only reliable solutions but also as potential revenue sources for small businesses," said Lindsay Aramayo, who contributed to the report detailing these developments.
Moreover, thousands of distributed battery systems are becoming part of virtual power plants (VPPs), aggregating local resources to function as a singular energy source. Companies like Sunrun and Tesla partner with LUMA to manage these systems, providing financial compensation to participants for their contributions. This innovative model provides a dual benefit: business owners can leverage solar energy for their operations while contributing to grid stability and receiving financial incentives.
However, small business owners must consider potential challenges before making the switch. The initial investment for rooftop solar and battery systems can be significant, requiring careful financial planning and assessment of return on investment. Moreover, ongoing maintenance and potential grid regulations are factors that need attention. It’s crucial to evaluate individual business needs and consult with energy experts to tailor the best solution.
The growing momentum of rooftop solar in Puerto Rico reflects broader trends in sustainable energy solutions, signaling a shift that small businesses should not overlook. With the right approach, adopting renewable energy technologies can not only enhance resilience but also provide a competitive edge in today’s energy landscape.
