Dates: 26 – 30 August 2019
Organisation: Renewables Academy (RENAC) AG
Register/Website: Green Energy Summer School IIIa: PV Off-Grid Systems – from Stand-Alone to Hybrid Mini-Grids

Description: The current trend in rural electrification using solar PV systems moves in two major directions: Small systems using innovative ownership and financing models (e.g. PAYGO) and larger mini-grids where conventional power sources (e.g. Diesel generators) are being hybridized with or fully exchanged by solar PV systems combined with large Li-Ion storage systems. In your training at RENAC you will focus on the technological aspects of both developments. This will enable you to talk at eye level to consultants, experts and solution providers. Going beyond technological aspects, we will facilitate the exchange of ideas and experiences on key success factors for rural electrification. Hands-on exercises and working with real-life equipment in our training center will enrich your learning experience and is always named one of the highlights of a training at RENAC by our participants.

This training suits those who:

  • Are staff of international development cooperation organisations, REAs, development banks, private companies, etc.
  • Desire to be involved in rural electrification projects using solar PV
  • Have no solid solar PV knowledge base

After the seminar, you will be able to:

  • Evaluate suitable applications for PV off-grid systems
  • List all major components and identify their functions
  • Identify energy efficiency as one key success factor
  • Describe the ways systems can be coupled (AC and/or DC)
  • Evaluate options to replace an existing (diesel) generator with a PV off-grid system.
  • Calculate how much fuel and emissions can be saved using PV off-grid systems.
  • Differentiate between stand-alone and hybrid operation.
  • Analyse the functionality of an energy management system
  • Visit a potential project site and analyse the solar resource
  • Size a solar PV array and battery storage (lead-acid and Li-Ion) to meet the energy demand of a rural electrification project
  • Wire-up a small off-grid system and test its functionality
  • Assess key success factors for rural electrification projects
  • Evaluate project risks and mitigation strategies
  • Discuss how an “enabling environment” for mini-grids can be created
  • Explain business/ownership models (e.g. PAYGO)
