Historical Trends in access and technology

Using large scale data with SHSs

Large data sets can: • predict micro trends through macro

analysis • identify relationships between energy

profiles and other variables • Provide a feedback loop for optimizing

future designs

Solar potential vs location

Pay as You Go (PAYG) Solar

PAYG accelerates access (~2-3x higher uptake) by:

• Providing financing for customers and supply chain players

• Improving trust in off-grid power by spreading risk

Off Grid Electric (OGE) collaboration

• OGE operates over 100,000 systems in Tanzania, Rwanda, Cote d’Ivoire • Previous work with OGE’s solar home system hardware data • Collaboration will generate insight into household energy usage patterns

and influencing factors and lead to better system design
