SUPPLIERS AND PRODUCTS ASSESSMENT
Procurement of solar components typically starts by a thorough quantitative assessment of both suppliers and products on the market.
On-site, evidence-based audits are the tools of choice to evaluate and benchmark the capability of suppliers and factories to deliver quality products:
- Quality Management System Audits
- Manufacturing Process Audits
- Product Development Assessments, etc.
STS also offers specialized audits and assessments, including:
- Supply chain audits and mapping
- Environmental audits
- Intellectual property infringement risk assessments
- Product qualification assessments, etc.
PRE-DISPATCH INSPECTION
The presence of qualified inspectors in the factory during production of your components is, by far, the most efficient and most cost-effective way to ensure quality of the components delivered to your project site.
With a track record of more than 10 years of PV equipment inspection, STS wrote and published the first Industry Standard (STS-STD-PVM1©) for approval of PV modules manufacturing and dispatch. Today, this Standard is used by most of our clients.
Following successful deployment of STS-STD-PVM1©, our clients receive a Certificate of Conformity that may be used to demonstrate to other PV assets stakeholders the level of quality secured during manufacturing.


POST-DISPATCH INSPECTION
STS offers inspection and test services directly at your project site to evaluate the state of health of your PV plant:
- Assessment of transportation or installation damage
- Assessment of damage due to a weather event
- Warranty claims
- Full health assessment through technical due diligence, etc.
TESTING
STS partners with carefully qualified ISO17025-accredited PV testing laboratories to provide a complete one-stop-shop experience. We assist our clients in establishing the most pertinent testing plan, identifying the relevant testing location to perform the test and follow-up the testing execution to finally interpret results and data.
Data matters, especially when the test plan is well designed and the results are properly analyzed.


TECHNICAL ADVISORY
Thanks to our continuous presence at the manufacturing factories, STS advisors are continuously updated about the latest trends, the new failure modes or the upcoming risks that a buyer of PV equipment may encounter.
We help establish quality management plans, support procurement contracting, assist with warranty claims, and carry out technical due diligence, on both operating and manufacturing assets.
