Solar energy has become a critical tool for expanding electricity access in regions where traditional grid infrastructure is limited, expensive, or unreliable. Pay-as-you-go (PAYG) solar financing models have been especially transformative, letting households afford systems through small mobile-payment installments rather than a large upfront purchase.
Why Solar Fits Energy-Poor Regions
Building traditional grid infrastructure to remote or low-density areas is often prohibitively expensive, while distributed solar — from small home systems to mini-grids — can be deployed faster and without the transmission infrastructure a centralized grid requires. This has made solar a leading tool for addressing global energy poverty.
Pay-As-You-Go (PAYG) Solar Models
| Model | How It Works | Where Common |
|---|---|---|
| PAYG solar home systems | Small daily/weekly mobile payments unlock system use via remote-controlled locking | Kenya, East Africa broadly |
| Solar mini-grids | Community-scale solar serving a village or cluster of homes | Bangladesh, rural India |
| Microfinance solar loans | Small loans specifically for solar system purchase | Various developing regions |
Case Study: Kenya
Kenya has been a global leader in PAYG solar adoption, with companies using mobile money infrastructure (like M-Pesa) to collect small daily payments for solar home systems — unlocking electricity access for millions of households that couldn’t afford a lump-sum purchase or lacked grid connection entirely.
Case Study: Bangladesh
Bangladesh built one of the largest off-grid solar home system programs in the world, bringing electricity to millions of rural households through a combination of microfinance and NGO-supported distribution networks, significantly expanding rural electrification beyond what grid extension alone could achieve.
Case Study: India
India has pursued both large utility-scale solar development and distributed rural solar mini-grids, using solar to leapfrog traditional grid buildout in remote areas while simultaneously scaling up its national utility-scale solar capacity among the largest in the world.

Frequently Asked Questions
How does solar energy help developing countries?
It provides electricity access without requiring expensive, slow-to-build traditional grid infrastructure.
What is pay-as-you-go (PAYG) solar?
A financing model where households make small mobile-payment installments to unlock use of a solar home system.
How has Kenya used solar to expand energy access?
Through PAYG solar companies using mobile money infrastructure to collect small daily payments for home systems.
What is a solar mini-grid?
A community-scale solar system serving a village or cluster of homes, common in rural Bangladesh and India.
Has Bangladesh had success with solar electrification?
Yes — it built one of the largest off-grid solar home system programs in the world.
Is India using solar for both large and small-scale energy access?
Yes — India pursues large utility-scale solar development alongside rural distributed solar mini-grids.
Why is solar cheaper than grid extension in remote areas?
Solar avoids the cost of building and maintaining transmission infrastructure to low-density or remote locations.
