Solar Photovoltaic Module Testing Lab

Centre for Energy Research and Development (CERAD) took its initiative by establishing Solar Photovoltaic Module Testing lab with the technical assistance of Chinese general certification (CGC) and some German consultants. This facility is first of its own kind which is maintained as per International Quality and Performance standards with the help of Government of Punjab in Kala Shah Kaku Campus, UET Lahore. The lab is providing its services to both Government and private sectors regarding PV Module Qualification testing. The lab implemented the PV Quality standard IEC 61215, IEC 61701 and safety standard IEC 61730-2. Services provided to the stakeholders includes but not limited to: Test the PV module Performance and comparison with name plate specifications

  1. Evaluation of PV module’s performance under different environmental conditions
  2. Assess the degradation rate and manufacturing quality
  3. Detect degradation effects after long periods of outdoor exposure
  4. Verify system design Qualification Besides technical testing and validation, lab also offers its services in training of students and trainers about PV Module Quality standards, design failures and their determination through qualification testing procedures.
