Project Overview
A private commercial client operating a farm in Polo Industrial Ezeiza, Buenos Aires, required a hybrid solar + energy storage system to store excess solar generation, perform peak shaving, reduce demand charges, and ensure continuity during grid outages. Contracted power stood at 120 kW, with demand charges forming a major cost.
Our company delivered an 80 kW / 160 kWh hybrid solar + energy storage system featuring high conversion efficiency and hybrid liquid-air cooling. Fully integrated with the site’s PV arrays, the system was commissioned in December 2025. Results included demand reduction to 60 kW, approximately 90 % self-coverage, and up to 55 % energy cost savings.
