Project Portfolio Summary
Throughout 2025, De La Sol has completed a diverse range of solar and energy-storage projects across Illinois — from compact residential rooftop systems to large-scale, multi-inverter installations with full battery backup capability. Each project reflects our commitment to craftsmanship, safety, and high-performance renewable-energy solutions tailored to the unique needs of homeowners and businesses.
Our installations feature industry-leading equipment from Qcells, SolarEdge, Enphase, REC, and Jinko, utilizing racking systems such as SnapNrack, IronRidge, Unirac, and S-5! for long-term durability. De La Sol’s work consistently meets or exceeds Illinois Shines and utility interconnection standards, ensuring compliance, reliability, and lasting value for our clients.
In early 2025, we reached a major milestone with our first battery installation in Annawan, IL, marking the beginning of our expansion into solar-plus-storage services. Since then, we’ve completed multiple battery-backed systems across the state — including Kirkland, Kingston, Milledgeville, Rock City, McNabb, and Lisle — integrating SolarEdge Home Batteries and Energy Banks for complete backup power and energy-management solutions.
Our portfolio also includes challenging and high-capacity installations such as the 18.45 kW dual-inverter system in Flanagan and the 17.22 kW battery-integrated system in Kingston, demonstrating our ability to handle advanced designs and complex site conditions with precision.
From Peoria’s steep-pitch rooftop to Pinckneyville’s service-breaker derating, every project showcases De La Sol’s expertise in solving on-site challenges, delivering clean and efficient solar systems that perform at or above expectations.
