Test and Measurement of Solar PV Installations

The production and use of renewable energy is stimulated by the European Union and via government incentives (e.g. through RES directives) and the prices for solar panels are dropping, leading to a growing number of solar panel installations. With this the demand for initial and periodic testing of the solar panels is growing.

Site survey, installation and commissioning of solar installations demands attention to safety, sustainability, reliability and efficiency / output of the solar panel system.

Several guidelines and legislation is applicable:

  • IEC 62446:2009 (Minimum requirements for system documentation, commissioning tests and inspection)
  • IEC 60364-6 (Low-voltage electrical installation – part 6: verification)
  • NEN 1010 / NTA 8013 (The Netherlands)

The IEC 62446 demands several tests & measurements that must be provided to the end-user, when installing a solar panel system:

  • Visual inspection: is the installation wired correctly? No damage to cables during installation?
  • Insulation resistance measurement (Riso)
  • Earth continuity measurement (Rpe)
  • PV String short circuit current (Isc)
  • PV String open circuit Voltage (Uoc)
  • Solar irradiance
  • Roof orientation and pitch

To safely install new solar panels (in line with the international standards) and to optimize the periodic testing of solar panel installations Nieaf-Smitt has developed the EazyPV tester. Easy and effective testing of all solar installation parameters in one device. The solar panels do not need to be opened/dismantled for this, the uniform solar panel connectors can be connected directly on the EazyPV.

The new solar PV installation tester EazyPV includes all functionalities to perform pre-installation site surveys and measure the electrical safety and performance of installed PV systems in line with the international IEC 62446 standard. Enabling contractors to safely, thoroughly and effectively install and maintain solar PV installations.

The new high specification IRM100 combines irradiance measurement with a hosts other features to enable solar PV and solar thermal contractors to carry out site surveys quickly and easily. The versatile device uses a precision PV cell sensor for the highly accurate irradiance measurement, displaying results in either W/m2 or BTU/h/ft2.

The EazyPV and IRM100 testers include all of the necessary functions to measure the electrical safety and performance of PV systems as well as irradiance. Additionally the kit is suitable to conduct site-surveys for potential installations; providing the information needed to calculate estimated annual solar irradiation and system yields of PV and solar thermal systems, as described in several local guidelines.
