SERIS can assist project owners and developers in the design of their PV systems for performance optimisation and to meet the highest quality standards, in particular for installations in the tropics. For example, SERIS has designed and commissioned a PV system that, since 2011, has been operating in Singapore with an exceptionally high performance ratio of almost 90%. SERIS assists its clients until the systems are fully operational and perform as originally planned.
Typical PV system services offered by SERIS are tabled below.
Initial estimation of annual energy yield and performance ratio (PR)*, based on the following criteria:
Yield assessment of annual energy output and PR*, based on the proposed system design (by client) and various data for the global horizontal irradiation from several sources (by SERIS). This includes shading analysis and quantification of system losses
All “Yield assessment” services, plus:
All “Optimised system design for high performance” services, plus:
All “third-party verification” services, plus detailed review of:
All “Project due diligence” services, plus:
* The performance ratio PR is the ratio of actual AC yield of a PV system over the theoretically expected DC yield. The latter is based on in-plane irradiance measurements as well as the module’s indoor power output under standard test conditions (STC).
