Quality testing and assurance photovoltaics
The yield from your photovoltaic investment is only as good as the quality of the system – when it functions at its best, the highest possible yields are achieved. Solarpraxis’ experts accompany your project from planning through to completion and beyond.
Thanks to our consultancy and testing services, you will be assured that the specifications agreed upon will be followed and all parameters optimized. At the same time we can support you in optimizing cycles and speeding up processes.
Overview of our services:
Planning phase
- Advice when selecting components (modules, inverters, mounting frames etc.)
- Review of installation design (e. g. string connections, inverter capacity utilization)
- Shading analysis
- Yield assessment report
- Assistance when obtaining construction permits (glare reports, EMC reports)
- Assistance with grid connection approvals
- Review of quotations
- Assessment of economic efficiency
Construction phase
- Inspection and testing of received goods
- Measurement of module output by an independent institute
- Visual inspection of components and construction quality (e.g. module assembly, DC cabling)
