  1. 1. Whole System IntegratedRenewable Energy Infrastructure For Distributed Off-Grid Electric Service Delivery w w o reuinen tn lo w .sln xs t a a m a r io .c
  2. 2. NOW is the Time to Scale Up RenewableEnergy Solutions for the Developing World ENERGY ACCESS FOR ALL IS POSSIBLE  Renewable energy (RE) can “leapfrog” the electricity grid THE TECHNOLOGY IS PROVEN AND RELIABLE  PV panels have no moving parts and can last 50+ years OUR EARTH NEEDS LOW-CARBON ENERGY SOURCES  RE can replace diesel generators and kerosene lamps NOW THE LONG-TERM COST EFFECTIVE CHOICE  Lifetime cost of ownership lower than diesel gen or kerosene WIRELESS TECHNOLOGY CREATES NEW OPPORTUNITIES  Many independent systems can be managed as a network  Mobile banking technology will allow new financing models 2
  3. 3. Developing the Global Off-Grid Renewable Energy Industry• Whole Systems at Pico through Macro Scales• “Code Quality” Off-Grid Installations for Rural Places• Installer Training, Certification and Professional Support• Wireless Networking for Central Monitoring & Control• Solar Energy Industry Development and Coordination• Public Education & Market Development 3
  4. 4. Multi-Scale Distributed PV• “Pico”• “Micro”• “Macro”• Mini-Grids
  5. 5. Pico-Scale PV - < 20 W• Kerosene lamp alternative• LED lighting• Mobile phone charging• AM/FM radios• Portable or “Plug and Play” user installation• Low-cost – consumer products• 1 – 5 year life expectancy• Affordable to many NOW
  6. 6. Micro-Scale PV 50 to 1000 Watts• Schools, clinics, community centers, offices, SME (businesses), homes, ICT centres• Generator and/or Kerosene Alternative• Lighting, computers, phones, internet, refrigeration, water pumping, entertainment, fans, tools• Hardwired for permanent installation• Ideally installed by trained technicians• User education and support required• Without supplementary charging, power availability varies with weather patterns• Expected battery life - 5 to 10 years• Expected system life - 20+ years
  7. 7. Macro-Scale PV1kW to 100 kW+ • Usually hybrid w/ other generators (diesel, biodiesel, biomass, wind, microhydro) • Well designed and built systems should last decades • Must be professionally installed and maintained • Requires load management and conservation awareness • Large batteries with 10+ years expected life • Improved battery technology is coming • Grid-interactive systems great for backup power
  8. 8. “Code Quality” SystemsLast Longer & Work Better No More “Spaghetti Solar”
  9. 9. Professionally Installed Off-Grid Systems Are Distributed Energy Infrastructure Reliable Service – Predictable Expenses – Quiet – Clean sunepi.org solar-aid.org
  10. 10. Building The Off-Grid Industry Scaling Up Requires Market Infrastructure• Distribution Channels for Quality Tested Products• Installer Training & Certification Programs• Business Development and Financing Photos - Walt Ratterman - www.sunepi.org
  11. 11. Wireless Communication and Control Networks• Remote Communication and Control Via Mobile Networks and Internet• Enables Centralized Monitoring of Widely Distributed Off-Grid Systems• Low Voltage Alerts To Address Problems Before They Destroy Batteries• Manage Rural Electric Infrastructure as a Single Network• Remote Control Enables Pre-Paid Billing and Fee-For-Service Systems
  12. 12. Pre-Integrated Whole Systems Pre-wired NEXUS (power centers)
  13. 13. Quality “Balance of System” Parts Like a chain, a circuit is only as strong as its weakest link Fuses and Circuit Breakers Lugs and TerminalsBattery Meters and Controllers Lightning Protection 13
  14. 14. “Nexus” Whole System Integration Simplifies System Design, Configuration and Installation
  15. 15. Proper Materials + Quality Workmanship = Long Lived, Efficient systems
