TBQ‑2C Total Solar Radiation Sensor for Zhenfa Pakistan Solar Power Plant

---

Customer Requirement

The client’s requirements for solar-powered surveillance hardware are as follows:

• Need reliable total solar radiation measurement to calculate PV system efficiency, compare actual power output vs theoretical yield.
• Field environment is harsh: frequent sand wind, high ambient temperature, strong ultraviolet radiation. Sensors must withstand long‑term outdoor desert operation without frequent maintenance.
• Data output should match local site data acquisition system, easy to integrate into existing PV monitoring platform.
• Full set solution: not only radiation sensor, but also complete meteorological station including wind speed & direction, temperature‑humidity sensor, installation bracket, junction box and field installation guidance.
• Strict project delivery timeline: equipment should arrive before site construction & commissioning phase to avoid delaying overall project progress.

Communication Process

At the early stage, our technical team communicated repeatedly with the project engineering team both online and offline.

The customer first shared site environment description and project drawing, and raised concerns about local desert sand‑storm influence on sensor lens and measuring accuracy. They also mentioned many imported sensors in local market had high cost and slow after‑sales support.

We listened to their pain points: high‑cost imported spare parts, long replacement lead time, worries about lens dust accumulation affecting measurement result. Then we introduced TBQ‑2C total solar radiation sensor practical desert‑project references. We discussed installation options: one option is mounting sensor directly on PV panel support frame as shown in picture; another option is integrating sensor into full‑function PV weather station. After comparing site layout, the customer finally selected dual‑layout solution: part TBQ‑2C sensors are fixed on PV array for panel‑plane irradiance monitoring, and others are assembled on meteorology station for horizontal total radiation collection.

We also confirmed signal output type, cable length, installation accessories and delivery schedule step‑by‑step, adjusted package to adapt long‑distance sea transportation to Pakistan.

Yantai Sensor Solution

Combined with Pakistan desert PV site real‑working condition, we delivered customized monitoring solution:

Project Result & Customer Feedback

All TBQ‑2C total solar radiation sensors and meteorological station hardware were delivered on schedule. On‑site installation and commissioning work has been completed as shown in project photos.

The radiation sensor works stably in high‑temperature and sand‑dust desert conditions. Real‑time solar radiation data is smoothly transmitted to plant monitoring platform. The data supports theoretical power generation comparison, PV module performance analysis, and assists operation team to make scientific O&M decisions.
Project engineering team gave positive feedback:

“The TBQ‑2C solar radiation sensor runs well in Pakistan desert environment. The data is reliable. The complete set of accessories and remote technical guidance greatly helped our field construction work. Comparing with imported products, it brings obvious advantage on project cost, and delivery cycle is much more satisfying.”

This Zhenfa Pakistan solar project becomes a typical overseas reference case for Yantai Sensor TBQ‑2C total solar radiation sensor, proving that our solar irradiance monitoring hardware can adapt large‑scale ground‑mounted photovoltaic projects under harsh desert climate.
