Start Up Tech Sales in Siem Reap, Cambodia

Help connect solar lights and biomass cookstoves with rural communities in Siem Reap, Cambodia, providing access to clean light and safe cooking.

d.light S300
Solar lantern
  • Up to 16 hours of bright light or 100 hours on the bed light setting
  • Much brighter, safer, and more efficient than a kerosene lamp
  • Two-year warranty & lifespan of 5+ years
  • Also charges mobile phones
The S300 features 4 brightness settings, providing up to 16 hours of bright light (100 hours on the bed light setting)

This project has been completed.
Thank you to all who contributed.

d.light D20
Solar Home System
  • All-in-one reliable lighting and mobile charging for home and small business
  • Simple operation
  • Long lasting battery
  • Easy mobile charging

Kopernik acknowledged the challenges Community Translation Organisation (CTO) experienced during their technology distribution and initially agreed to extend the original project timeframe. In January 2017 however, we agreed to reduce the repayment amount from US$3,857 to US$871.34 and allowed CTO to continue to sell the unsold technologies, retaining any revenue as a donation from Kopernik to their organisation. CTO notified us many times that they would make the payment but they never honoured the commitment.

We have spent considerable time chasing this payment but CTO have now in the last month, become unresponsive. We have therefore decided to forfeit this payment and officially close this project, notifying our donors that CTO did not meet their payment obligation. We will not be working with CTO again.

To read in more detail about the challenges CTO had, you can read this project report.


Families living in Prasat Bakogn and Pouk districts in Siem Reap, Cambodia, spend a lot of time collecting firewood for their traditional cookstoves. Each family spends about eight hours a week collecting fuelwood from nearby forest or fields. Those who don’t live near the forest spend around US$12/month to buy firewood. Firewood collection is threatening the forest and wildlife.

Almost half of the population in rural areas of Cambodia have limited access to electricity. Kerosene lanterns and battery boxes are commonly used, but kerosene lanterns produce dim light and battery boxes need to be charged, which involves taking them to a recharging station and paying a fee.

How we can help: 

By introducing d.light S300 solar lights to these communities, children can use them for reading at night, while parents can use them to work in the evening,  for example to make handicrafts.

The d.light D20 solar home system is an affordable alternative to the battery box. A solar panel costs less and lasts much longer than a battery box, and will also save money on recharging.

A biomass cookstove can save up to 60% of fuelwood compared to traditional cookstoves. The time usually spent on collecting fuelwood and lighting fires can then be spent other income-generating activities or education, and otherwise improving the families' livelihood.

Who are we working with: 

We are helping members of the community, whose farming productivity is reliant on the availability of electricity and safe cooking methods in Siem Reap. Our local partner, Community Translation Organisation, has been working with these communities for many years to improve their living standards and protect the environment from degradation.


The Community Translation Organisation will distribute the technologies to farmers in four communities in two districts over one year. The Community Translation Organisation will repay the money collected from technology sales to Kopernik, to be reinvested in more technologies for last mile communities.
