Module Aim and Orientation

Due to significant advances in technology and drops in prices for solar panels, solar pumps have become an economical, technically and environmentally viable alternative to conventional pumping systems.

Nevertheless, few people are aware of the potential and risks associated with solar pumping for irrigation. Often the solar pump is not optimally integrated into the irrigation system, which results in inefficiencies. Consequently demand amongst producers is low and the reluctance of financial institutions to finance them is high.

The GET INFORMED module provides essential information for agricultural advisors and financial service providers to understand the operating principle of SPIS and to differentiate between the individual system components. Moreover, it starts to describe how the different configurations of the components can influence the performance of the entire system. The GET INFORMED module will allow agricultural and financial service providers to support potential users of SPIS with up-to-date information on the pros and cons of the technology and its individual components.

Brief Description of the Module

Compared to conventional energy systems, the use of solar energy has some specific characteristics, which must be considered when planning a Solar Powered Irrigation System (see DESIGN module).

The following steps describe in detail the available configurations and individual system components of an SPIS operating under constantly varying conditions due to daily and seasonal fluctuations.

The description of the individual components of an SPIS and the relations between them are preceded by information on the basics of solar energy and irrigation. When solar energy and irrigation are combined in one production system we call this a Solar Powered Irrigation System. Typical configurations of SPIS are presented in this module and in the DESIGN module.
