Solar-powered irrigation systems have become a financially viable alternative to electric and diesel water pumps for irrigation of agricultural crops. This is mainly due to the fact that:
The following key indicators and financial statements help to assess the financial viability:
Assessing the financial viability of the SPIS is a complex procedure which should be accompanied by financial experts. This part of the module only gives an overview of key data and indicators to be generated. Note that all projections and calculations:
1. the revenues from
2. Capital expenditure (CAPEX)=long term, one-time, investments in non-consumable parts of the business, like
3. Operating expenses (OPEX) = ongoing operational and maintenance costs (fixed and variable)
When comparing PV systems to diesel or electric pumping systems the following statements apply:
These factors influence the financial viability of the different options; hence, different scenarios should be elaborated before taking a decision.
