Sun King (formerly Greenlight Planet) is the world's largest off-grid solar company. In 2007, a kerosene-lamp fire in rural Kenya moved founder Anish Thakkar and others to resolve to “replace dangerous, costly kerosene with safe, affordable solar.” It launched its first Sun King solar lamp in 2009 and combined a direct-sales network — organizing local residents village by village as agents (saathi, “friend” in the local language) — with pay-as-you-go (PAYG) financing in small installments, putting it within reach of households with no electricity and no credit history. It now sells through an agent network of 15,000 across 40 countries, has sold over 12 million units cumulatively, and by early 2025 is said to have reached about one-fifth of off-grid households. Replacing kerosene reduces the risk of fire and indoor air pollution, extends evening hours for work and study, and cuts household fuel spending by around $75 a year.

Sun King (formerly Greenlight Planet, Inc.): The world's largest off-grid solar, replacing kerosene lamps. The letter is B; certainty is medium. Unconfirmed concerns are placed under “Watching.” (As of 2026-Q2; estimate based on public information.)
Main narrative
One person’s story (N1)
+ before → after
In a village in Bihar, India, near 9 p.m., a father and son who had finished selling eggs were packing up a stall lit by a Sun King lamp and heading home. According to a visit account by an accompanying investor, in one village 100 of 150 households had bought a lamp within four months. The saathi sellers (farmers, teachers, homemakers who work about an hour in the evening) often doubled their household income.

Positive / negative effects
+ effects
- The independent environmental award Ashden judged that even the smallest model is brighter than a kerosene wick lamp, makes cooking, study, and work easier, and reduces the risk of kerosene-related fire and indoor air pollution. It estimated that about 5 million units in use cut CO2 by about 450,000 tonnes a year and save each household about $75 a year on kerosene and charging.P1 independent recognition (Ashden) / Ashden
− effects (confirmed)
- No confirmed −.
- Debt and device-shutoff risk for low-income households under PAYG
- The gap between self-reported reach and independently verified values
- Meeting the energy demand of “the next billion,” and expanding into home appliances like solar refrigerators and TVs and into inverters.
A second look
The core + is safe, affordable light for households without electricity and the improvements in study time, income, and health that come with it (people and nature), backed by the Ashden Award and independent media reporting. That said, PAYG is effectively credit, and how device shutoff on non-payment affects low-income households is an ongoing point to watch. Scale and reach numbers are largely self-reported; note the gap from independently verified values.

How to read this assessment
- Reachable upper bound (ceiling): a confirmed − sets the ceiling, and independently verified + decide the position within it. + do not cancel out −.
- The weight of evidence is not symmetric: only confirmed − are counted; the volume of disputes or allegations goes under “Watching.” + are counted from independent evidence, while an organization’s own PR is treated as “reference.”
- Size is not value: scale is not used in the assessment. Matters that stay within money or competition—investors, shareholders, sanctions, trade secrets—are also excluded.
- The letter (assessment) and certainty (how reliable the information is) are separate axes.

Because they are AI-generated they may contain errors, and they are opinion and commentary, not statements of fact.
