Renewable and Appropriate
Energy Lab Mission Statement
Developing and implementing
science, engineering, and policy tools
to solve problems of inequality in
access to energy services, and
innovating to sustain the planet.

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

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
