Cost analysis Solar vs Generator and Solar vs Hybrid
This tool is intended to be used in order to compare the costs of buying, running and servicing a water scheme with a diesel generator vs an equivalent Hybrid (Solar+ Generator) pumping solution.
- Costs are estimated for a period of 25 years (lifespan of solar panels, the longest of all components).
- Costs that are common for both systems (e.g. salary of a guard for the water scheme) have been taken out, since they would have no impact in the cost comparisons analysis.
- Costs are calculated including pumping equipment (pump, generator, solar panels, invertor and accessories).
- By adding additional columns, other costs could be included in the analysis if necessary. Before proceeding to use the tool, read the Word document ‘Technical Briefing – Economic Assessment’, where principles of Net Present Value analysis are explained.
