[August 23, 2025] – GF New Energy Technologies is pleased to announce the successful completion of a 60-day aging test on its solar tracker controller, further validating the product’s durability and reliability under extreme operating conditions.
The test officially started on June 23, 2025, and concluded on August 23, 2025, following a structured four-phase process to ensure comprehensive performance verification.
1. Preparation (Day 1)
Samples & Equipment: Fully functional controllers, high–low temperature chamber, adjustable DC power supply, electronic load, and precision multimeters were prepared.
Plan: Test duration was set at 60 days, with alternating temperature cycles: –40°C for 16 hours and 70°C for 16 hours.
Safety: Equipment calibration was confirmed, high-voltage warnings were set up, and fire safety equipment was prepared.
2. Pre-Check (Before Test)
Visual Inspection: No cracks, loose connectors, or damaged components.
Initial Baseline: MPPT accuracy, efficiency, and key component temperatures were recorded for later comparison.
3. Aging Test Execution (Core Phase)
Installation: Controllers were wired with input/output loads, and thermocouples were fixed on MOSFETs and capacitors to monitor internal heat.
Operation: Samples were placed into the chamber under controlled temperature cycles.
Monitoring: Data was logged every 60 minutes automatically, with daily manual inspections for smoke, odor, or parameter deviations. Any anomaly triggered immediate shutdown and inspection.
4. Post-Test Evaluation
Performance Retest: After a 24-hour stabilization at room temperature, all baseline parameters were re-measured.
Pass Criteria:
MPPT accuracy degradation ≤ 2%
Efficiency drop ≤ 3%
Temperature rise ≤ 10°C
Physical Inspection: No signs of leakage, solder cracks, or component damage were found.
Realistic Stress Conditions: Test parameters were carefully designed to simulate real outdoor operation without overstressing components.
Risk-Point Monitoring: Continuous monitoring of internal temperature and electrical performance ensured early detection of potential failures.
Standardized Process: Identical testing conditions were applied across all samples, ensuring results were consistent and reproducible.
After 60 days of rigorous testing, GF solar tracker controllers successfully met all performance and reliability criteria. This achievement reinforces GF’s commitment to delivering robust, field-proven solutions for global solar projects.
With the growing demand for highly reliable Solar tracking systems, this test result once again demonstrates GF’s ability to provide customers with controllers that perform reliably under even the harshest conditions.
