Core Pain Points of Photovoltaic Power Plants: Why Ordinary Weather Equipment Falls Short?

Photovoltaic power generation efficiency is directly affected by on-site weather conditions such as irradiance and module temperature. Without accurate and real-time photovoltaic-specific weather data, integrators face numerous operational and commercial risks. Below are the core pain points and shortcomings of ordinary weather equipment.

I. Power Generation Loss and Revenue Uncertainty Risks

Pain Point: Inability to accurately measure key parameters such as irradiance, leading to large deviations in power generation calculations, difficulty in evaluating power plant PR values, troubleshooting performance anomalies, and providing reliable data for grid settlements; power generation losses caused by dust and module overheating cannot be quantified.

Impact on Integrators: Failure to meet expected power generation can lead to disputes and damage reputation; lack of data support when handling complaints increases commercial risks.

Shortcomings of Ordinary Equipment: Sensor spectrum and angle response do not match photovoltaic modules, with large temperature drifts and poor stability, resulting in systematic deviations in irradiance data; sensors are prone to contamination, leading to long-term low data that goes undetected.

II. Low O&M Efficiency and High O&M Costs

Pain Point: Lack of reliable weather data prevents preventive O&M; when equipment fails, it's hard to distinguish between weather and equipment causes, leading to blind O&M where costs exceed benefits; ordinary weather equipment has high failure rates and unstable communications, resulting in misguided O&M decisions.

Impact on Integrators: O&M costs compress profits, blind O&M is seen as a lack of professionalism, equipment damage and extended downtime affect customer benefits, hindering future cooperation.

Shortcomings of Ordinary Equipment: Lack of design adapted to photovoltaic scenarios, insufficient protection levels, poor communication compatibility, frequent data interruptions, no fault self-diagnosis function.

III. Difficulty in Quantifying Dust/Soiling Effects, Blind Cleaning Decisions

Pain Point: Lack of effective means to monitor soiling losses, inability to scientifically determine module cleaning timing, commonly resulting in over-cleaning or under-cleaning issues.

Impact on Integrators: Over-cleaning increases costs, under-cleaning leads to power generation losses, customers tend to blame integrators, and blind cleaning may damage modules.

Shortcomings of Ordinary Equipment: No soiling monitoring function, low data precision in simple equipment, unable to provide reliable support for cleaning decisions.

IV. Inaccurate Module Temperature Measurement, Distorted Performance Evaluation

Pain Point: Ordinary temperature sensors are improperly installed, insufficient in number, or lack precision, leading to large temperature data deviations and inability to reflect actual module operating temperatures.

Impact on Integrators: Distorted PR value calculations, difficulty in troubleshooting equipment hazards, expanded power generation calculation deviations, affecting project acceptance.

Shortcomings of Ordinary Equipment: General-purpose temperature sensors not adapted to photovoltaic scenarios, low precision, large temperature drifts, lack of scientific installation guidance.

V. Poor Adaptability to Harsh Environments, Short Equipment Lifespan

Pain Point: Ordinary weather equipment has low protection levels and poor weather-resistant materials, prone to aging, corrosion, and damage in outdoor environments, requiring frequent maintenance and short lifespan.

Impact on Integrators: Frequent equipment damage increases spare parts and maintenance costs, data interruptions fail to support ongoing decisions, customers question integrator selection capabilities.

Shortcomings of Ordinary Equipment: General-purpose design not optimized for photovoltaic outdoor scenarios, protection level below IP67, narrow high-low temperature resistance range, no anti-UV or anti-corrosion capabilities.

VI. Complex System Integration, Poor Compatibility

Pain Point: Ordinary weather stations have non-unified communication protocols and non-standard interfaces, poor compatibility with photovoltaic monitoring and SCADA systems, easily forming data silos, complex installation and debugging.

Impact on Integrators: High integration difficulty and long cycles increase implementation costs and delay delivery, data cannot be linked for analysis, poor customer experience.

Shortcomings of Ordinary Equipment: Lack of industrial-grade integration design, does not support MODBUS and other mainstream protocols, no open API interfaces, no standardized installation and debugging processes.
