Most of our municipal partners fund projects through a combination of the Inflation Reduction Act's Direct Pay provision, which lets tax-exempt entities like cities and counties receive the full 30% federal investment tax credit as a cash payment, plus federal and state grants, and energy savings that begin offsetting costs from day one. Big Sun's team helps you identify and capture every funding source available before a project ever breaks ground.
Not necessarily. Big Sun Solar is a TIPS-awarded vendor, which means municipalities, schools, and public agencies can procure our services through The Interlocal Purchasing System's cooperative purchasing program. It's a legally compliant path that can save months of procurement time compared to a traditional RFP.
Solar alone won't power your facilities during an outage, but solar paired with battery storage will. Big Sun designs battery-backed Resilience Hubs that keep critical facilities like community centers and emergency shelters online when the grid fails. Harris County is deploying this model right now across multiple sites.
We do. Big Sun provides long-term asset management across your entire portfolio: monitoring, maintenance, and performance optimization for the life of the system. Your facilities team won't need to become solar experts, and you'll have one accountable partner from groundbreaking through year 25.
Minimally. We phase construction around your facility schedules and operating hours. Our City of San Antonio program spans 54 active city facilities, including fire stations, libraries, and community centers, and services continued uninterrupted throughout construction.
Depending on project structure, savings can begin as soon as systems are energized. Across our municipal portfolio, partners are projected to save tens of millions of dollars over 25 years. The City of San Antonio program alone is projected to deliver $7–11M in cumulative savings.

"We get the real benefit on our insurance premium for our inventory so that was the biggest financial driver on top of tax credits plus accelerated depreciation. I would tell my fellow dealers to contact Big Sun Solar to look at the opportunity and have them crunch the numbers."
