Sol Systems has announced the completion of its Eldorado solar project located in Saline County, Southeastern Illinois. The project, developed in partnership with Nextracker as the solar tracking system supplier and SOLV Energy as the construction contractor, has a capacity of 342 MWdc.
The project incorporates an agrivoltaics initiative through collaboration with the American Farmland Trust to cultivate Kernza, a perennial grain, beneath the solar panels. The initiative, announced earlier in 2025, is among the first large-scale efforts in US to combine row-crop agriculture with utility-scale solar.
Moreover, the project features a long-term community benefits programme with funding directed toward six local organisations. This initiative builds on earlier community impact commitments established under the power purchase and community investment agreement signed in 2020 between Sol Systems and Meta.
Earlier this month, Sol Systems secured an initial commitment of about $80 million in interconnection letters of credit from Great Bay Renewables to support its MISO portfolio. The revolving facility will cover refundable milestone deposits to MISO and readiness deposits in PJM.
