Published on 8 May 2025

Keeping the Light On investigates why customers who struggle to pay for 3 – 20 Wp Tier 1 Paygo Solar-home systems (SHS) without arrears fall behind on instalments in Kenya and Uganda.

The project, led by GOGLA with support from EnDev and RVO SDG 7 Results, started with an analysis of company portfolio data, which showed that non-payment of solar home systems (SHS) is a significant challenge, with 40% of customers in Kenya and Uganda struggling to pay for their PAYGo SHS. The likelihood that a customer will struggle to pay for their SHS increases over time. While only 20% of new customers (who have had a system for three months or less) struggle with payments, this figure doubles when they have had the system for between four to six months and continues to rise.

The project surveyed 2,602 customers from d.Light, Sun King and Engie, defined as those who paid less than 66% of the amounts due in the last 90 days, and conducted 12 qualitative deep-dive interviews in Q4 2024. Interviews with the management of several PAYGo solar companies complemented this primary research and were crucial in the recommendations design.

Main findings on the root causes of non-payments

Financial constraints are the primary cause of missed payments. Only 33% of Kenyan and 29% of Ugandan customers who struggle to pay report having stable monthly income. In both countries, 40% of customers have other debts, further constraining their repayment.

Unforeseen climate shocks amplify payment difficulties among customers. Over 50% of customers in both countries reported that droughts, crop diseases, floods, and extreme heat affected their income.

The presence of alternatives and a lack of consistent need for the SHS lead some customers to skip payments. In Kenya, 27% of customers who skip payments have grid access, compared to 15% in Uganda. Customers connected to the electric grid tend to use their SHS as a backup solution. Additionally, around 10% of customers in both countries pay for multiple SHS simultaneously.

Technical issues with the SHS were common among respondents and could impact customer satisfaction, potentially leading to lower repayments. 49% of customers in Uganda and 28% in Kenya reported experiencing technical issues with their system at least once. While these issues did not prevent customers from using the systems, dissatisfaction with persistent unresolved technical issues can lead to non-payment.

Although customers appear to be satisfied with the customer onboarding/education, there is a gap in knowledge of contract terms. More than 50% of Ugandan and a third of Kenyan customers interviewed do not accurately know their remaining balance or the duration they still have to pay.

Recommendations

At the company level

1. Refine income and needs assessment in the Know‑Your‑Customer processes.

Practical Tips

  • Expand the range of KYC questions to understand accurately alternative sources of light and electricity, projected use of the system, and pre-identify complexities in payment.
  • While the KYC process can be costly, especially for smaller SHS, it is a crucial way to ensure the quality of the portfolio and should therefore be considered as an investment.

Rationale:

  • Better predict future ability to pay.
  • Improve assessment of willingness to pay.

Root causes addressed:

  • Financial constraints.
  • Presence of alternatives and lack of need.

Potential implementation challenges:

  • Length of KYC procedure and cost associated with it.
  • Securing honest and reliable feedback from respondents.

2. Align the incentive structure of staff to ensure agents select customers who will be able to pay in the long run.

Practical Tips

  • Tie the sales agents’ incentives to their customers’ repayment performance over the longest repayment time possible and reward the sales agents with the best portfolio quality.
  • Structure customer care agents around a portfolio of customers they would manage throughout their whole client cycle life.

Rationale:

  • Improve sales agents’ portfolio through incentives.
  • Improve relationship with customers.

Root causes addressed:

  • Financial constraints.
  • Presence of alternatives and lack of need.
  • Poor customer onboarding and education.

Potential implementation challenges:

  • Striking the right balance between offering attractive incentives for agents and preserving company margins.
  • Designing a simple, transparent approach that encourages agent buy-in and active participation.
  • Delivering comprehensive training to ensure consistent understanding and execution across field teams.
  • Developing a user-friendly tracking system that enables agents to identify customers needing follow-up and to easily record interaction outcomes. 
  • How to structure of agent models and management, including how to incentivize good agent performance, are detailed in this briefing note
  • Identify the right key performance indicators (KPIs) to measure performance and benchmark their performance with peers with the PAYGo PERFORM Monitor
  • Conduct an internal self-assessment, especially on elements that contribute to good customer service and fair and respectful treatment of customers by agents/customer care
  • Engage a third party to assess processes, including how they perform on the fair and respectful treatment of customers
  • Further understand how their customers perceive treatment by agents/customer care and outsource the implementation of the lean data consumer protection survey

3. Set up frequent touchpoints in the contract inception phase.

Practical Tips

  • Prioritise the first few months (typically the first two to four months).
  • Design a structured post-onboarding process for new customers, including a clear outreach strategy (via SMS and calls) to ensure they are properly onboarded.
  • Leverage these touch points to ensure continuous customer education
  • Identify all potential challenges faced by new customers and make their resolution the highest priority.
  • Analyse the repayment patterns of new customers and consider repossession for those facing persistent difficulties, as they are highly likely to become long-term bad payers.

Rationale:

  • Maximise the chances of having the client repaying after they miss some payments.
  • Identify early customers who are likely to face challenges.

Root causes addressed:

  • Financial constraints
  • Poor customer onboarding and education.
  • Issues with the PAYGo/ mobile money system.

Potential implementation challenges:

  • Maintaining continuity in customer touchpoints to foster trust and long-term relationships, while organising staff roles accordingly.
  • Determining the optimal frequency of customer interactions to maximise impact while keeping operational costs in check.

4. Train call centre agents to understand the root causes of non-payment and offer tailored solutions to customers.

Practical Tips

  • Embed decision trees (flowcharts visualizing a series of actions and their potential outcomes if selected) in ticketing systems and explain the rationale to agents.
  • Deliver regular refresher training on repayment tools and scripts.
  • Track call outcomes and recovery rates to identify coaching needs.

Rationale:

  • Improve understanding of root causes of non-payment to better anticipate issues.

Root causes addressed:

  • Financial constraints.
  • Poor customer care relationships.

Potential implementation challenges:

  • Balancing comprehensiveness (to capture root causes) with simplicity (to ensure practical and consistent implementation).

Self-assess elements that contribute to good customer service

5. Investigate ways to always improve the products.

Practical Tips

  • Identify the most common issues faced by customers.
  • Work with your supplier to address such issues.

Rationale:

  • Maintain high customer satisfaction

Root causes addressed:

  • Technical issues with the SHS.

Potential implementation challenges:

  • Defining MECE (mutually exclusive, collectively exhaustive) categories of customer issues that are easy to measure and directly actionable.
  • Ensuring suppliers are able and incentivised to act on customer feedback to reduce recurring problems over time

6. Create a continuous feedback loop.

Practical Tips

  • Always enquire customers who struggle to pay to identify the extent of their financial situation and their lack of regular need for an SHS, to explain why they are skipping some days of payment.
  • Use these findings to fuel and adapt the selection criteria for the next cohort of customers in the country.
  • Systematically analyse payment trends by cohort in each country and understand payment trends per profile to identify the best repayment management practices.
  • Analyse the cost vs. benefits of the implemented changes.

Rationale:

  • Keep improving performance over time.
  • Take into account evolving environments and customer profiles

Root causes addressed:

  • Financial constraints.
  • Presence of alternatives and lack of need.
  • Poor customer onboarding and education.

Potential implementation challenges:

  • Striking the right balance between offering attractive incentives for agents and preserving company margins.

At the industry level

1. Standardize metrics and share data.

Practical Tips

  • Join the GOGLA PAYGo Performance and align as much as possible with the refined KPIs being developed.

Rationale:

  • Be able to benchmark performance, identify emerging risks and reach quicker to market changes.
  • Improve credit management collectively.
  • Reduce due diligence costs when seeking capital.

Root causes addressed:

  • Financial constraints.

Potential implementation challenges:

  • Integration with companies’ customer relationship management (CRM) systems and alignment with existing data collection processes to streamline operations.

2. Share data on customers and agents for better risk management.

Practical Tips

  • Create a shared database of sales agents to help identify and exclude fraudulent or unethical actors. Data protection regulations might make it difficult in some contexts, but there should be at least background checks with contact references.
  • Expand credit data exchange with other market participants and credit reference bureaus.

Rationale:

  • Avoiding agents who had unethical behaviour in the past

Root causes addressed:

  • Financial constraints (for customers).
  • Poor customer care relationship (for sales agents).

Potential implementation challenges:

  • Addressing regulatory constraints.
  • Ensuring seamless integration with companies’ internal systems to enable swift and informed decisions.
  • Achieving broad adoption among off-grid solar (OGS) providers to ensure relevance and scale, to make it relevant.

At the ecosystem level

Drive more climate adaptation funding towards the OGS sector to respond to the impact of climate shocks

Practical Tips

  • Estimate, measure and track the impact of OGS products on the resilience and adaptation of customers to provide evidence that could unlock additional financing towards OGS.

Rationale:

  • Better predict future ability to pay.
  • Improve assessment of willingness to pay.

Root causes addressed:

  • Financial constraints.
  • Presence of alternatives and lack of need.

Potential implementation challenges:

  • Length of KYC procedure and cost associated with it.
  • Securing honest and reliable feedback from respondents.
