Remote Environmental Test Chambers For Solar Photovoltaic Products

1. Product Name and Purpose

2. Product Features

Electrodynamic Vibration Shaker

• Precise Vibration Control
  • The electrodynamic vibration shaker is capable of generating a wide range of vibration frequencies, typically from 5 Hz to 2000 Hz. This broad frequency spectrum allows for the simulation of different types of vibrations that solar PV products may experience during transportation, such as the low - frequency vibrations from road travel or the high - frequency vibrations caused by rough handling. The vibration amplitude can be accurately adjusted, with a range of 0.1 mm to 100 mm (peak - to - peak), enabling the reproduction of various levels of vibration intensity.
  • It can generate vibrations in multiple axes, usually including vertical, horizontal, and sometimes rotational axes. This multi - axis capability is vital as solar PV products may be subjected to complex vibration patterns in different directions during transportation and installation. For example, solar panels may experience vibrations in multiple axes when being transported on a truck or during the installation process.
• Customizable Vibration Profiles
  • Operators have the flexibility to create custom vibration profiles according to specific test requirements. These profiles can include continuous vibrations, intermittent shocks, or complex sequences that mimic the actual vibration scenarios solar PV products encounter. For instance, a profile can be designed to simulate the vibrations during a long - distance transportation of solar panels, including vibrations on different road surfaces and during loading and unloading.
• High - Performance and Durable Design
  • The electrodynamic vibration shaker is constructed with high - quality materials and components to ensure long - term reliability and performance. The shaker's frame is made of sturdy steel, providing a stable and rigid platform for generating vibrations. The electromagnetic drive system is engineered to be efficient and precise, delivering consistent vibration levels over extended periods of testing.

Climate Test Chamber

• Wide Climate Range
  • The climate test chamber integrated with the vibration shaker can achieve a broad range of temperature, humidity, and solar radiation conditions. The temperature can typically be adjusted from - 40°C to + 85°C, allowing for the simulation of extreme cold and hot environments that solar PV products may face in different geographical regions. The humidity control can maintain relative humidity levels from 10% to 95%, enabling the testing of how products respond to different moisture levels.
  • Additionally, the chamber can simulate various levels of solar radiation, typically ranging from 0 W/m² to 1200 W/m². This is crucial as solar PV products need to perform optimally under different sunlight intensities, and the ability to replicate these conditions in a controlled environment helps in evaluating their performance and durability.
• Fast Climate Transitions
  • The chamber is capable of rapid temperature, humidity, and solar radiation transitions. For example, it can achieve temperature transition rates of up to 5°C/min, humidity transition rates of up to 5%/min, and can quickly adjust the solar radiation levels. This is essential for simulating sudden changes in the environment, such as a cloud passing over a solar panel or a change in weather conditions.
• Uniform Climate Conditions
  • The interior of the climate test chamber is designed to provide uniform temperature, humidity, and solar radiation conditions throughout the test volume. The temperature variation within the chamber is typically within ±1°C, the humidity variation is within ±5% relative humidity, and the solar radiation uniformity is within ±5% of the set value. This ensures that all parts of the solar PV products being tested are exposed to the same environmental conditions, providing reliable and consistent test results.

Integrated Control and Monitoring

• User - Friendly Interface
  • The entire test system is controlled through a user - friendly interface that simplifies the operation process. The interface allows operators to easily set and adjust the test parameters for both the vibration shaker and the climate test chamber. It provides a clear display of the current test status, including vibration frequencies, amplitudes, temperature, humidity, solar radiation levels, and elapsed test time.
• Comprehensive Data Acquisition and Analysis
  • Equipped with a comprehensive data acquisition system, the test system records all relevant data during the test. This includes vibration measurements, temperature and humidity profiles, solar radiation data, and any observed product failures or performance changes. The data can be stored in a secure database and analyzed using advanced software tools. The system can generate detailed test reports, including graphs, charts, and statistical analysis, to help engineers and researchers understand the test results and make informed decisions.
• Remote Monitoring and Control
  • Many models of this combined test system offer remote monitoring and control capabilities. This feature enables operators to monitor the test progress and adjust the test parameters from a remote location, such as a control room or an off - site office. It is particularly useful for large - scale testing operations or when immediate access to the testing system is not possible.
