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

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

  • 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.
