H-1B sponsorship profile: ECA Solar LLC. Across U.S. Department of Labor LCA disclosures, ECA Solar LLC filed 4 Labor Condition Applications covering 4 H-1B worker positions between fiscal year 2023 and fiscal year 2025. The employer’s DOL certification rate sits at 75% (3 certified of 4 filed), a useful proxy for how cleanly their prevailing-wage attestations pass the Labor Department’s preliminary review before USCIS adjudication.

Compensation spread. Offered wages on ECA Solar LLC’s H-1B petitions range from $82,000 at the low end to $135,000 at the high end, with a petition-weighted average of $96,500. That range reflects the mix of occupations the company sponsors, led by Solar Photovoltaic Design Engineer (2 petitions at $82,000 avg), followed by SOLAR PHOTOVOLTAIC DESIGN ENGINEER and Director of Valuations and Project Finance. H-1B salaries reported on LCAs must meet or exceed the DOL prevailing wage for the role and worksite, so the spread also tracks wage-level geography and seniority.
