2. NOW is the Time to Scale Up Renewable
Energy 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

4. Multi-Scale Distributed PV
• “Pico”
• “Micro”
• “Macro”
• Mini-Grids

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. 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. Macro-Scale PV
1kW 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. “Code Quality” Systems
Last Longer & Work Better
No More “Spaghetti Solar”

9. Professionally Installed Off-Grid Systems Are
Distributed Energy Infrastructure
Reliable Service – Predictable Expenses – Quiet – Clean

• Manage Rural Electric Infrastructure as a Single Network
• Remote Control Enables Pre-Paid Billing and Fee-For-Service Systems

12. Pre-Integrated Whole Systems
Pre-wired NEXUS (power centers)

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 Terminals
Battery Meters and Controllers Lightning Protection 13

14. “Nexus” Whole System Integration
Simplifies System Design, Configuration and Installation

15. Proper Materials + Quality Workmanship =
Long Lived, Efficient systems
