Challengesin Solar PV Performance Monitoring

Solar PV plant owners, EPC contractors, O&M teams, and energy managers need accurate on-site solar radiation data to evaluate power generation performance, identify abnormal losses, and improve long-term operation efficiency.

Lack of Accurate Solar Irradiance Data

Many PV systems rely only on inverter power output or public weather data, which cannot accurately reflect the real solar radiation conditions at the project site.
Difficult Performance Ratio Analysis

Without real-time irradiance data, it is difficult to compare actual PV power generation with available solar resources, making performance ratio analysis incomplete.
Module Temperature Impact

PV module temperature directly affects power generation efficiency. Without module temperature monitoring, O&M teams may fail to identify thermal loss or abnormal module heating.
Delayed Fault Detection

Dust accumulation, shading, cable faults, inverter abnormalities, and module degradation may reduce power output, but these issues are difficult to identify quickly without environmental reference data.
Lack of Centralized Monitoring

Distributed PV projects, rooftop PV systems, and utility-scale solar farms often lack a unified platform for solar radiation, temperature, weather, and power generation data comparison.
