Our team of experts is also available for any technical advisory assistance you may need in the solar space. 








Suppliers and Products Assessment 

Procurement of solar components typically starts by a thorough quantitative assessment of both suppliers and products on the market.


- Factory audit

   - Quality management system audit

STS also offers specialized audits, including supply chain audits, environmental audits, intellectual property audits, innovation audits, etc. 



Pre-Dispatch Inspection 

- Production planning inspection

- Production supervision

- Pre-shipment inspection

- Container loading supervision.


Following successful deployment of this scope, our clients receive a Certificate of Conformity that may be used to demonstrate to other stakeholders the level of quality deployed during manufacturing. 

Post-Dispatch Inspection 

Inspection services on your project site to evaluate the state of health of your PV plant:

- Electroluminescence

- Visual inspection

- Infrared thermography


Excellent tools to reduce impact of transportation and installation damage, to monitor degradation of the PV plant, or to provide a full assessment, for instance in the case of a technical due diligence. 



STS partners with carefully-qualified ISO 17025-accredited PV testing labs to provide a complete one-stop-shop experience. We assist our clients in establishing the most pertinent testing plan, identifying the relevant lab location to perform the test and follow up on testing execution and interpretation of the data. 

Data matters, especially when the test plan is well designed and the results are properly analyzed. 


STS advisors are continuously updated about the latest trends, the new failures modes or the upcoming risks that a PV component buyer may encounter. 

We help establish quality management plans, support procurement contracting, support warranty claims, and carry out technical due diligence, on both operating assets and manufacturing assets.
