					LEW Jen Sern, NUS final year student, has won a High Achievement Award in the 2012 Innovation & Research Award competition at the NUS Faculty of Engineering, for his final year research project for the Degree of B. Eng (Engineering Science). The project entitled “Advances in luminescence-based characterisation of silicon wafer solar cells” was conducted at SERIS. Jen Sern was supervised by Prof Armin ABERLE (SERIS’ CEO), Dr Bram HOEX (SERIS’ SiPV Cluster Director) and Mr Matthew P. PELOSO (SERIS’ PhD candidate) for this work.

Solar Energy Systems

SERIS can assist project owners or project developers in the design of their solar PV systems with a strong focus on optimisation of PV systems’ performance and highest quality standards; specifically for tropical environments. At the same time SERIS stays alongside the client until the systems is fully operational as originally planned. The services are described in the following table:

Yield estimation	Yield assessment	Optimized system design for high-performance
Initial estimation of annual energy yield and performance ratio*, based on the following criteria: Location Module technology Inverter concept Tilt angle Azimuth	Yield assessment of annual energy output and performance ratio*, based on the proposed system design (by client) and various data for the global horizontal irradiation from several sources (by SERIS). This includes shadow analysis and quantification of system losses	All "Yield Assessment" services, plus: Optimization of the proposed system design (mechanical, electrical up to medium-voltage) for high-system performance, based on existing performance ratio* benchmarks




3rd-party verification	Project Due Diligence	Full project partnership
All "Optimized system design" services, plus: Suitability of the key plant components Detailed review of system design (mechanical, electrical up to medium-voltage) and cross-check against current industry practices Optional: Review against given guidelines (statement of compliance)	All "3rd-party verification" services, plus: Detailed review of: Track record of suppliers and turnkey provider Project structure and obligations of project parties Technical warranties Project management Operations & Maintenance concept Project risks and mitigations Optional: Financial modeling Factory inspections	All "Project Due Diligence" services, plus: Site visit prior to project closure Construction monitoring Final acceptance Operations & Maintenance reviews Analytical on-site monitoring with calibrated equipment Optional: Sample testing of solar modules

* Performance Ratio, defined as the ratio of actual AC yield over the "theoretical" maximum DC yield, which is based on irradiance measurements and assuming full conversion into electricity.
