Pakistan Zhenfa Solar PV Weather Monitoring Project

项目背景

Pakistan has abundant solar resources, with high levels of solar irradiation throughout much of the year and favorable conditions for photovoltaic power generation. At the same time, growing electricity demand has increased the need for additional power capacity. Compared with conventional fossil-fuel generation, solar power offers a way to add electricity supply while reducing fuel dependence and associated emissions.

The Zhenfa project was developed as a large-scale ground-mounted photovoltaic power plant, making use of Pakistan’s available solar resource to increase clean electricity supply and support the local energy mix. Once operational, the plant is intended to provide additional power to the regional grid and reduce part of the reliance on conventional thermal generation.

The project also includes a PV weather monitoring system for collecting solar irradiation, air temperature and humidity, wind speed, and wind direction data. These measurements provide field conditions needed for plant operation and maintenance, generation performance assessment, and environmental data analysis. The project therefore provides practical experience that can be referenced in the planning and operation of similar utility-scale PV plants in Pakistan.

Project Scope: Solar module installation, weather monitoring, equipment commissioning, and operational data collection

On-Site Equipment & Applications

The project included photovoltaic modules, a PV weather monitoring system, solar radiation sensors, and related electrical and communication equipment. The main equipment and their roles are as follows:

PV Module System

PV modules were installed in planned arrays across the solar field. The mounting structures, module positioning, and electrical connections were checked during installation to ensure the arrays were correctly assembled for normal power generation.

PV Weather Monitoring System

The weather station was deployed to monitor solar radiation, air temperature, relative humidity, wind speed, and wind direction around the PV field. These measurements provide local environmental data for plant operation, performance assessment, and maintenance analysis.

太阳辐射传感器

Radiation sensors continuously measure the solar irradiance received at the site. Combined with PV power output, the measurements can be used to review generation performance under different weather conditions and identify deviations that may require further inspection.

Data Acquisition & Communication Equipment

The monitoring system includes data acquisition and communication equipment for collecting sensor readings and transmitting them to the monitoring platform. After installation, the team checked sensor connections, communication status, and data transmission to confirm that the recorded measurements were available for ongoing plant monitoring.

Project Implementation

1. Site Preparation

Before installation, the project team surveyed the PV field and reviewed the site layout, solar exposure, equipment positions, and installation conditions. Suitable locations were identified for the module arrays, weather monitoring system, and solar radiation sensors. All incoming equipment was checked for quantity, model, and installation condition before field work began.

2. PV Module Installation

The PV modules were installed according to the planned array layout. The team checked the support structures, module alignment, fastening points, cable routing, and electrical connections during installation. These checks helped maintain consistent array installation and reduce issues during subsequent electrical and system testing.

3. Monitoring Equipment Deployment

The weather monitoring equipment and radiation sensors were installed at designated positions within the PV field. The installation team completed sensor mounting, wiring, communication connections, and protection of outdoor cables. After installation, the measured parameters were checked against expected field conditions to verify that the sensors and data acquisition system were working correctly.

4. System Commissioning

Following equipment installation, the PV and monitoring systems underwent functional checks and trial operation. The team reviewed sensor readings, data acquisition, communication status, and transmission to the monitoring platform. Any wiring, configuration, or communication issues identified during testing were addressed before the system was handed over for routine operation.

Project Highlights

Integrated PV and environmental monitoring: The project combines PV power generation with weather and solar radiation data collection at the same site.
Multi-parameter weather measurement: The monitoring system records solar radiation, temperature, humidity, wind speed, and wind direction for plant operation and performance analysis.
On-site radiation data: Solar irradiance measurements provide local reference data for evaluating PV generation under changing weather conditions.
Coordinated installation and commissioning: PV equipment and monitoring equipment were installed and tested as part of the overall project implementation process.
Practical reference for PV projects: The project provides field experience in weather monitoring, radiation measurement, data acquisition, and system commissioning for similar solar power applications.

客户反馈

The customer found the installation and commissioning process straightforward, particularly the on-site work for the weather monitoring and solar radiation equipment. After the system was put into operation, the team could check the local weather and irradiance data alongside the PV plant’s operating records, which made it easier to review changing site conditions.

They also noted that the monitoring equipment was practical for routine operation and did not require complicated daily handling. Having continuous records of radiation, temperature, humidity, and wind conditions gave the operations team a more consistent basis for checking plant performance and carrying out routine maintenance.
