Sunto - All-out Solar Irradiance Sensor

The All-out Solar Irradiance Sensor is an innovative device engineered for comprehensive solar radiation monitoring without the need for sun trackers or moving components. This device effectively integrates the functionalities of a pyranometer, pyrheliometer, albedometer, spectroradiometer, and a monoaxial tracker controller into a single unit. It computes a variety of measurements, including the Optimal Inclination of tracked PV panels and the Maximum Irradiance Angle by assessing direct and diffuse solar irradiance. Additionally, it provides detailed measurements of Global Horizontal, Direct Beam Horizontal, Global Tilted Irradiance, tailored to different PV technologies, as well as Ground Reflected and Reflected Tilted Irradiance across four spectral bands: IR, Red, Green, and Blue. By enhancing fault localization and providing precise data, it reduces operational costs and increases energy yield, offering a cost-effective alternative to traditional solar monitoring systems.

Sunto - All-in Panel Sensor for Real-time PV Monitoring

The All-in Panel Sensor (APS) is an innovative clamp-on device designed to enhance photovoltaic (PV) panel monitoring by measuring string current, temperature, and tilt without disrupting panel connection. This device stands out for its ability to facilitate the agile, accurate, and cost-effective management of solar assets. It plays a critical role in fault diagnosis by correctly identifying and locating issues such as broken fuses, wire rust, connector faults, shading, soiling, and tracking misalignments. By predicting early degradation signs in solar panels, it supports more efficient operation and maintenance strategies. APS is instrumental in augmenting the performance ratio (PR) and in forecasting solar plant production. The system operates within real-time and predictive frameworks using cutting-edge machine learning and deep learning algorithms, ensuring the optimization of maintenance interventions across diverse solar installations. The patent-pending technology includes optional components like a wireless docking station and a solar irradiance sensor.

Connecting

Sunto - SPS Solar Power Management System for Off-Grid Applications

The Sunto SPS is a solar power supply control board specifically engineered for off-grid applications, ensuring optimal performance of devices powered by solar energy. By interfacing with a photovoltaic panel and a 7.4V lithium-ion battery, the SPS efficiently manages energy resources, adapting to varying sunlight conditions. Utilizing a Maximum Power Point Tracking (MPPT) algorithm, it maximizes power extraction from the solar panel in real-time, enhancing conversion efficiency under diverse loads and solar intensity. Furthermore, the integrated battery management system monitors critical parameters like voltage, temperature, SOC (State of Charge), SOP (State of Power), and current to secure the battery's longevity and operational integrity. Communication is conducted via the I2C protocol for precise residual capacity monitoring. SPS technology is tailored for environmental monitoring stations requiring solar-powered, autonomous wireless data transmission, assisting in maintaining performance in changing environmental conditions. The technology has been tested and validated by Enel Green Power.

Tracking

Sunto - STO (Solar Tracker Optimizer) System

The STO System is engineered to enhance the tracking precision of single-axis solar trackers. Utilizing a meticulous approach, it continuously monitors the tilt of photovoltaic modules, analyses deviation from optimal positions, and computes parameters for tilt correction, ensuring optimal alignment and increased energy output. At its core, the STO System incorporates three primary algorithms: the ephemeris algorithm for tracking the sun's position based on time and geographic coordinates, the shadowing algorithm to address inter-tracker shading effects, and the ground tilt algorithm to adjust for east-west ground tilt variations. These features are vital for improving the performance ratio of PV installations and preventing financial drawbacks from inefficiencies. Tested in large-scale plants like those managed by Enel Green Power, the STO System has consistently raised energy production by 2-5% annually. The system is delivered as a portable unit comprising multiple STO components, an industrial-grade tablet, and essential accessories, all securely housed in a robust, waterproof enclosure.
