Solar PV on packhouses: GreenCape business case demonstrates 15% saving in electricity costs

Results
The modelling shows:

  • Economies of scale are important, with favourable returns in all scenarios for a large (500kWp) system.
  • For smaller systems, access to favourable financing and loan terms is a key issue determining feasibility.

Four packhouses that have implemented solar PV already are showcased as case studies, demonstrating savings of up to 18%.

GreenCape has developed a business case for solar PV for packhouses, with the key insights and opportunities summarised in this short industry brief and for those interested in the full modelled results and more in depth consideration of the factors driving the financial feasibility a full report is available.

Bio-ethanol production in South Africa: An objective Analysis. BFAP 2005. 

Introduction

High oil prices and uncertainties regarding future reserves as well as the phenomenon of global warming have led to countries considering alternative means of energy generation. As the South African economy is highly dependent on oil, and since much of the agricultural sector has been suffering from low commodity prices, the question of the viability of ethanol production from agricultural crops, has surfaced. This report does not try to answer this question directly but rather attempts to analyse the impacts some of the critical factors influencing ethanol production will have on its viability.
