Solar Module Testing

Testing services to meet the needs of the Solar Industry

  • As a leading independent third party test laboratory, Westpak offers testing services to meet the needs of the Solar Industry in the areas of research and development, reliability, performance, pre-qualification, and logistics. Westpak understands that time to market is the largest hurdle solar companies face with new products. Solar developers who have taken advantage of Westpak's technical capability and test capacity have significantly reduced the schedule risks associated with the certification process by the discovery and resolution of problems throughout the product development cycle. Start-up clients are in the unique position of being time and resource constrained. Westpak has filled this gap for over 20 years by meeting the testing needs of start-up clients at our ISO 17025 accredited laboratories in San Diego and San Jose, CA. Westpak also understands the requirements for maintaining product confidentiality and makes special arrangements as required.

     

    Logistics
    Manufacturing, logistics and installation are three main cost centers related to the cost of solar.  Logistics includes the packaging, shipping, distribution, warehousing, and material reclamation.  These costs are expected to exceed the manufacturing costs of the module in the near future and significantly reduce profits.  Taking advantage of Westpak’s packaged product test capability is an opportunity for your firm to evaluate product and packaging changes that could enable significant cost reduction in both package and product.  Our experience has helped several clients improve the product and reduce packaging materials.  

    Logistics testing is conducted per industry standards published by organizations including IEC, ASTM, ISTA, and ISO.  Westpak has the expertise and frequently recommends changes to improve the product and package interaction to optimize performance.  ASTM D4728 and D3580 are typical standards for truck vibration and package resonance respectively.  ASTM D4169 and ISTA 2B are typical package performance standards which outline a series of test inputs designed to simulate the distribution environment.

    Research and Development
    As new technologies are developed, companies will need to verify production modules on a large scale.  Using a certification laboratory is costly in terms of time and money.  By leveraging the resources provided, Westpak’s clients conduct testing in a confidential environment while having access to the lab and their product under test.  Test parameters requested are often time based as defined in IEC 61215, 62108, 61646, 61730 and UL 1703 which include Thermal Cycling, Damp Heat, and Humidity Freeze.

    Reliability Testing
    Across the solar industry, reliability is an issue for warranties and determining the life expectancy of modules.  While there isn’t any one single model for accelerating the aging of modules, Westpak has the ability to provide testing services according to IEC 61215, 62108, 61646, 61730 and UL 1703 which include Thermal Cycling, Damp Heat, and Humidity Freeze.  Westpak can also conduct testing according to your own internal requirements.  

    Performance Testing
    Industry standards for performance are published by IEC and determine the performance limits of the modules.  Westpak can perform many of these tests and we are adding equipment to accommodate the needs of our clients.

  • Safety Testing
    Both UL 1703 and IEC 61730 address the safety aspects of the solar panel in terms of breakage and electrocution.  Solar panels operate under high DC voltage and current and any shading can cause "hot spots"  that can cause panel failure or fire.  These standards provide a rigorous test suite for identifying early design failures related to panel safety.

Service Highlights

The following are major portions of the Solar Tests being offered at Westpak. Additional solar related tests and solar logistics testing are available.

Background

Solar panels
What is Solar Panel Testing?

Global warming and the need for lower energy costs have created demands for alternative energies. By using Photovoltaic modules, solar energy has come to the forefront as an option that is both clean and affordable. The goal is to create an end product that is robust enough to withstand the environmental, mechanical, electrical and other challenges throughout the product’s life cycle. Westpak has the experience and knowledge to test your product to its full potential.

Overview of Testing Standards

Current Standards

Current Standards
IEC 61215/61646 –  These standards address PV (Photovoltaic) and thin-film PV modules respectively. Tests include design qualification, performance, durability, safety and robustness. These two standards are almost identical to each other in nature.

IEC 62108 – This standard addresses CPV (Concentrator Photovoltaic) modules. The test inputs are similar to IEC 61215 and 61646.

UL 1703 – This standard addresses safety concerns of solar modules. Some test inputs overlap with the IEC standards. Additionally material testing may be required depending on module design.
IEC 61730-2 – This is a relatively new standard, it addresses safety concerns and has some overlap with UL 1703.

Other Standards
ASTM E1171 – This standard outlines in detail the environmental (temperature/humidity) testing required in other IEC/UL/IEEE standards.

IEEE 1262 / 1513 – These standards address PV and CPV modules respectively. Both documents have been largely replaced by IEC requirements, which are similar.
