STEMIS Control — Agribusiness


Managing energy in large-scale irrigation systems is one of the biggest challenges in agribusiness. Diesel dependency, grid instability, and the need to keep pivots operating without interruption demand a level of intelligence that traditional systems simply cannot deliver. This is where STEMIS Control was put to the test.

Challenge: Hybrid microgrids supporting 4 irrigation pivots with high diesel dependency and increasing operating costs.

Solution: STEMIS Control deployed with intelligent BESS dispatch, generator management, and real-time energy optimization.

Result: Significant reduction in diesel consumption and operating costs — with rapid payback and strong annual return on investment.

STEMIS TCRW1 — Solar Power Plants

STEMIS TCRW1 — Solar Power Plants

The losses due to dirt are silent — but constant. Dust, dirt, and organic residue accumulate on photovoltaic modules every day, silently reducing generation without triggering any alarms. Manual cleaning teams are slow, expensive, and often unavailable at scale. The TCRW1 was designed to change this equation permanently.

Challenge: Manual module cleaning is slow, expensive, and risks damage — directly limiting generation recovery.

Solution: The TCRW1 autonomous robot has been deployed in various facilities — performing dry or wet cleaning, up to 2,500 modules/day, with remote monitoring via app.

Result: Proven generation gain after cleaning, with zero mechanical or electrical damage to the modules. Independently validated by Unicamp.

STEMIS Design — Large-Scale Industry

STEMIS Design — Large-Scale Industry

For large industrial operations, energy costs are one of the biggest threats to competitiveness. Peak tariffs, demand charges, and the complexity of correctly sizing a hybrid system cause most companies to hesitate—or worse, invest in the wrong configuration. STEMIS Design was created precisely to solve this.

Challenge: One of the largest furniture manufacturers in Brazil was facing high electricity costs with peak tariffs heavily impacting its monthly budget.

Solution: STEMIS Design generated the optimal hybrid microgrid configuration with a complete financial analysis—including purchase and lease options.

Result: The project demonstrated a highly attractive return on investment, with the client formally endorsing the solution through a letter of recommendation.

Solar tracking controllers

Solar tracking controllers

First Solar Tracker Controller (TCU) developed and manufactured on a national scale in partnership with TECSCI LTDA.

Challenge: Large solar farms face the constant challenge of maximizing energy capture throughout the day and maintaining availability through constant equipment communications.

Solution: To address this challenge, the TCS-150 was developed, a solar tracker controller with AI technology for optimal positioning (TrackBoost) and communication via the LoRaWAN protocol.

Result: With the implementation of the equipment and its technologies, your plant can generate up to 13% more energy during the day, maintaining availability and communication at rates above 99%.
