Greenlight Planet Kenya provides solar home systems on a pay-as-you-go basis to millions of homes across Kenya.

Our investment

Description of the investment.

BII’s investment in the company (also known as Sun King Kenya) is expected to improve quality of life for customers by financing the growth of solar home systems' sales. It will help improve access to clean and affordable energy, and financial services. The investment will reach primarily low-income peri-urban and rural consumers in Kenya. BII has supported the company through several loan facilities starting in 2020. BII’s current support for the company is through both direct lending and to Sun King Financing Limited as part of a receivable securitisation transaction (see dedicated page).

Impact information

Applies to investments made from 2019 onwards. The tabs in this section define what we expect to achieve through the investment, assessing the potential impact of the investment against six dimensions of impact. You can find more details on our methodology of assessing impact here.



Improve quality of life by extending access to affordable reliable and modern energy services and financial services (SDGs 7.1, 7.2 and 1.4)



Our investment will help to finance sales growth, by providing debt capital to fund GreenLight Planet's receivables book for Pay-as-you-go solar home system products, enabling more affordable access to energy services and unbanked customers to establish credit histories.


Stakeholder Geography Characteristics


Primarily (80 per cent) rural and peri-urban consumers. 77 per cent of current customers are low-income, living on less than $5.50 a day. 49 per cent live in relative poverty, living on less than $3.20 a day.

How much?

Scale Depth/Duration

The new facility is expected to reach up to c.3.2 million households in total.

Around 77 per cent of Greenlight Planet's customers are accessing off-grid solar power for the first time. On average, surveyed Greenlight Planet customers reported a 102 per cent increase in hours of light and a 75 per cent reduction of kerosene consumption after acquiring a solar home system.


  • Financial additionality: Local currency debt financing is not available in sufficient quantity from commercial lenders, who have a limited risk appetite to lend to off-grid solar companies.

Impact score

Impact score (at point of investment)

The Impact Score is a tool to help us manage our performance against our strategic impact objectives. It is designed to incentivise investments that support our productive, sustainable, and inclusive objectives. You can find out more here.

The Impact Score is published for investments made from 2022 onwards. The Impact Scores are calculated at the point of investment. We publish the Impact Scores of new investments annually, once the information has been externally assured by an independent third party.
