Every year on May 3rd, the world celebrates International Sun Day. First established in the United States in 1978, it was created to promote solar energy as a clean and affordable alternative to fossil fuels. Nearly 50 years later, that mission feels more alive than ever.

In 2026, businesses across the United States are not just talking about solar energy; they are investing in it. They are installing it, saving money from it, and inspiring others to follow. From schools in Manatee County to farms across Hillsborough and commercial properties throughout Tampa Bay, business owners are leading the solar movement and improving their operations every day.

This International Sun Day, we celebrate that progress and share what it looks like in real life.

Key Takeaways:

• International Sun Day is held on May 3rd each year and was first established in the USA in 1978 to promote clean solar energy.
• Florida businesses may qualify for a 30 percent federal solar tax credit, as well as full sales tax and property tax exemptions on eligible solar installations.
• Schools, farms, and commercial businesses are cutting energy bills by 40 to 70 percent after installing solar panels.
• 2026 is one of the best years for Florida businesses to go solar, with strong incentives available and electricity rates still rising.

The business case has never been stronger

Commercial electricity rates in the United States have increased over the past decade, and Tampa Electric rates have risen since 2020. A business spending $4,000 per month on power pays $48,000 per year.

Once installed and connected, solar begins producing electricity, helping lower utility bills. Many commercial solar systems in Florida pay for themselves in about 5 to 8 years, depending on usage and incentives. The 30 percent federal tax credit available in 2026 helps reduce the upfront cost.

Schools are showing everyone how it is done

Schools are some of the best candidates for solar in Florida. They operate during the day when panels produce the most power. Air conditioning, lighting, cafeterias, and computer labs all run during peak sunlight hours.

Tampa Bay Solar recently completed one of the largest school rooftop solar projects in Florida at the Manatee School for the Arts. The school saw immediate reductions in monthly energy costs. Those savings went directly back into classrooms, student programs, and staff resources.

That is solar in action. It is not just a green initiative. It is a financial decision that improves what a school can offer its students every single year.

Farms are cutting costs with Solar

Agriculture is one of the most energy-intensive industries in the country. Irrigation pumps, cold storage, and processing equipment run for hours every day. Electricity is one of the highest costs on any farm and one that keeps rising.

Farmers across Florida are installing solar systems matched to their operations. Over time, a 100-kW solar system can help a mid-size farm keep hundreds of thousands of dollars that would otherwise go toward electricity costs.

Solar is a natural fit for farms that run irrigation during the day. The sun powers the panels, while the pumps need electricity. Adding battery storage means the farm keeps running during outages and severe weather, which matters greatly in Florida during hurricane season.

Commercial businesses are locking in savings

Warehouses, retail centers, office buildings, and healthcare facilities across Tampa Bay are all part of the solar movement in 2026. Business owners are tired of unpredictable bills, and solar is the most effective solution.

One of the biggest wins is reducing demand charges. These are extra fees utilities charge based on your highest period of electricity use during the billing cycle. They can make up 30 to 50 percent of a commercial electric bill. A solar system paired with battery storage targets these charges directly and often eliminates them. Business owners who make the switch say the same thing every time. Their bills dropped, and they wish they had done it sooner.

Make 2026 your year

Florida has no sales tax on solar equipment and does not increase property taxes for adding solar. Businesses may also receive net metering credits that lower future bills. With the 30 percent federal tax credit available, 2026 is a strong year for Florida businesses to go solar.
