PV Quality Program

Solarif Risk Management established a wide-ranging PV Quality Program, which helps to manage the risks involved in the different stages of investing in PV thus leading to high quality, reliable systems.

The program entails

1

Factory risk assessment

Factory Risk Assessment (Upfront/During Production)

The Factory risk assessment exists of an extensive Technical Risk Assessment of the panel/inverter manufacturer’s production facilities/workshops, to verify conformance to quality standards set by Solarif and a Financial Risk Assessment which aims to determine the default risk of the manufacturer within the next years. Through this comprehensive due diligence, the quality of the panels/inverters is secured and made insurable by Solarif Insurance.

In-line quality inspection

In-line quality inspection (During Production)

Solarif Risk Management conducts randomly in-line checks to verify the implementation of Standard Operating Procedures (SOP’s). These quality audits are performed by Solarif Risk Management to verify conformance to standards set by Solarif through review of objective evidence. A system of quality audits may validate the effectiveness of a quality management system and ensures (through inline inspection) that the right raw material goes in the product. Solarif Risk Management evaluates at all different stages the production of the modules/inverters including packing, warehousing and loading, to coincide with the production run of the client’s finished goods. The purpose of these inspections is to certify that the quality level of the assessed materials meets Solarif’s quality standards.

Solarif Risk Management team will check among others:

  • BOM versus CDF
  • Raw materials and movement of materials of stock
  • Operational excellence of plant personnel
  • Witness testing on site
  • Review of the quality system
  • Check if product requirements are met (Verification of certifications)
  • Visual inspection
  • I-V measurement
  • Electroluminescence imaging
  • Dimensions and weight measurements
  • Frame Gap and/or Rubbing test

Standard pre-shipment inspection

Standard Pre-shipment inspection (SPSI) (After Production)

This inspection is performed by Solarif Risk Management as a quality control procedure and carried out at the panel manufacturer’s production lines on randomly chosen panels. It enables proper identification of goods, invoices and other documentation after production and prior to shipment and is commonly required by the investor/importer as a quality control guarantee. The purpose of this check is the documentation of faults and errors in the batch and the replacement of faulty panels preceding shipment to ensure the panel/inverter produced meets the requirements of the client.

Solarif Risk Management team of auditors will check among others:

  • Raw materials and movement of materials from stock
  • Packaging
  • Witness testing on site
  • Check if product requirements are met (Verification of certifications)
  • Visual inspection
  • I-V measurement
  • Electroluminescence imaging
  • Dimensions and weight measurements
  • Frame Gap and/or Rubbing test
  • Label and serial numbers check

post-shipment inspection

Post-shipment inspection (After Production and Transport)

This quality control procedure comprises the thorough check of the batches of PV panels upon arriving at the anticipated destination in relation to compliance purposes. It includes and verifies the quality and quantity of the shipped modules and identifies any transit damages, such as spin webs of micro cracks. When combined with a Standard Pre-Shipment inspection (SPSI), the post-shipment inspection provides the assurances that the modules received by the client are the same as those been shipped prior.

 

Solarif Risk Management team of auditors will check among others:

  • Visual inspection
  • Frame gap test
  • Rubbing test
  • Label and serial numbers conformity
  • Shipment documentation inspection
  • Packing material inspection

If you combine the inline quality inspection or the Standard Pre-Shipment inspection with the post-shipment inspection, one can easily identify transit-related degradation and damages due to transport.

5

Lab testing

Lab Testing

To assess the quality of certain modules and its components, Solarif Risk Management provides a wide range of environmental accelerated laboratory stress tests at independent testing facilities. To verify the conformity of solar products and intended use of the products, one or more of the following standards, among others, must be used:

  • Crystalline silicon terrestrial (PV) modules test according to IEC 61215;
  • Thin-film terrestrial (PV) modules according to IEC 61646;
  • PV module safety qualification according to IEC 61730-1 and IEC 61730-2;
  • Salt Mist for Photovoltaic (PV) modules according to IEC 61701;
  • Ammonia test for Photovoltaic (PV) modules according to IEC 62716.
