1 Scope and object
This International Standard defines the requirements for design, qualification and
performance measurements of photovoltaic pumping systems in stand-alone operation.
The outlined measurements are applicable for either indoor tests with PV generator
simulator or outdoor tests using a real PV generator. This standard applies to systems
with motor pump sets connected to the PV generator directly or via a converter (DC
to DC or DC to AC). It does not apply to systems with electrical storage unless this
storage is only used for the pump start up (< 100 Wh).
The goal is to establish a PV pumping system design verification procedure according
to the specific environmental conditions. This Standard addresses the following pumping
system design features:
-
• Power vs. flow rate characteristics at constant pumping head
-
• Pumping head vs. flow rate characteristics at constant speed
-
• System design parameters and requirements
-
• System specification
-
• Documentation requirements
-
• System design verification procedure
The object of this standard is to establish requirements in order to be able to verify
the system performance characteristics of the PV pumping system. For this purpose
the test set-up is outlined, the measurements and deviations to be taken are defined
and a checklist for the data mining is established.
