Data from the monitoring system of the UTE Autazes (AM) pilot project — August 2026.

Every string under continuous watch

In locations hours by boat from the nearest urban centre, availability is not secured by a field crew — it is secured by telemetry.

The two pilot arrays side by side in the operations panel, with the same 5.6 kWp capacity and different specific yield.

String-level readout, not plant-level

The platform reads current and voltage from every string individually. A soiled, shaded or degraded row shows up as a specific-yield deviation before it becomes a meaningful loss — with nobody walking the array.

Alarms across four severity levels

Critical, major, minor and warning. Every event is classified and routed, and the team decides what warrants a trip and what can be solved remotely. Over the measured period, both pilot arrays logged zero alarms at every severity.

Specific yield as the common yardstick

Raw kWh says nothing when arrays differ in size. Normalizing per installed kWp (kWh/kWp) makes arrays, sites and technologies comparable on the same basis — that is how the tracker gain was isolated.

Auditable environmental balance

Avoided CO₂, standard coal saved and tree equivalence are computed from energy actually metered, not from design estimates. That is what makes sustainability reporting traceable.

Autazes pilot: fixed-tilt versus tracker

We installed two identical 5.6 kWp arrays side by side, under the same sky, to measure the real gain of solar tracking at Amazonian latitude.

Across 11 consecutive days of measurement, the tracker array generated 30.4% more energy than the fixed-tilt array — and converted that difference into 30.4% more revenue.

Single-axis tracking delivered 28% more energy per installed kWp than the fixed-tilt array under identical irradiance and temperature conditions. In isolated systems, every percentage point of solar generation is diesel that does not have to travel up the river.

Photovoltaic Systems for the Rainforest

VP FlexGen Brazil designs, installs and operates hybrid photovoltaic systems in isolated communities across the Amazon. Each plant is a balance between high-complexity electrical engineering, river logistics and absolute respect for local biodiversity.

We operate where the conventional grid does not reach — replacing diesel gensets with clean solar power, without compromising supply stability.

Four pillars of our architecture

The engineering that makes it possible to run renewable generation at grid-grade performance inside isolated systems.

01

Grid-forming inverters

Historically, solar plants ran in grid-following mode: they depended on a voltage signal from the thermal machines to operate — if the grid went down, solar went down with it. Our architecture uses grid-forming string inverters that create their own voltage and frequency and behave like digital synchronous generators. This delivers black start, short-circuit current injection and synthetic inertia — indispensable capabilities in isolated systems.

02

1000 V AC architecture and LCOE reduction

Moving past the industry-standard 800 V AC, the 1000 V AC topology allows longer strings, less cabling infrastructure and a leap of more than 40% in power density. In utility-scale arrays, Balance-of-System (BOS) costs drop by 0.3 to 0.6 US cents per watt, with roughly 1% higher energy yield over the asset lifetime.

03

Granular storage, from cell to grid

Utility-scale batteries suffer from the barrel effect: a single weak cell drags down the performance of an entire block. Our architecture applies power electronics at string and pack level, treating each section independently. AI-assisted safety diagnostics anticipate thermal runaway and localized failures days in advance, cutting the Levelized Cost of Storage (LCOS) by around 20%.

04

Autonomous AI-assisted operation

Running hundreds of hectares in remote locations would demand a permanent field crew. The inverters execute multi-channel Maximum Power Point Tracking (MPPT) and Smart String Level Disconnection (SSLD) locally, while the AI cloud layer identifies broken strings and hardware anomalies remotely. Combined with self-cleaning and extreme-weather resilience, this turns island and riverside plants into self-optimizing power systems.
