SERIS can help project owners and developers design their PV systems to maximise performance and fulfil the highest quality requirements, particularly for tropical climates. SERIS, for example, designed and commissioned a photovoltaic (PV) system in Singapore that has been functioning with an extraordinarily high performance ratio (PR)* of 85-90% since 2011. SERIS’ project services begin with initial design and energy yield analyses, and continue throughout the project duration until the PV systems are fully operational and performing as expected.
Typical PV system services offered by SERIS:
Yield Estimation
Initial estimation of annual energy yield and performance ratio (PR)*, based on the following criteria:
- Location
- Module technology
- Inverter concept
- Tilt angle
• Azimuth
Yield Assessment
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 PV system losses
Optimized System Design for High-Performance
All “Yield assessment” services, plus:
• Optimisation of the proposed system design (mechanical, electrical up to medium voltages) for high system performance, based on existing PR as benchmarks
Full Project Partnership
All “Project due diligence” services, plus:
- Site visit prior to project closure
- Construction monitoring
- Testing & Commissioning (T&C)
- Final acceptance
- Operations and maintenance reviews
- Analytical on-site monitoring with calibrated equipment
Optional:
• Sample testing of PV modules
* The performance ratio PR is the ratio of actual AC energy yield of a PV system over the theoretically expected DC energy yield. The latter is based on in-plane irradiance measurements as well as the module’s indoor power output measured under standard test conditions (STC).
