Moonlight: Lantern powered by the Sun


As the light of the moon is a reflection from the sun, so is the power of the MoonLight lantern coming from the heat of the sun.  Moonlight is one of the practical and multi-functional solar-powered tools developed by Kamworks.    It can be used as a lantern when farmers go out to their farms early in the morning; it can be fixed in the house as a lamp to provide light at night; and it can even charge cell phones!

Moonlight is a good alternative for kerosene lamp in the rural areas or a battery flashlight that needs new batteries often. It is lightweight, safe and can be carried by children without fear of electric shock, smoke or fire.  It is also convenient since one day exposure of its small panel will provide power that will last for a maximum of 6 hours.

The lifespan of the Moonlight is 5 years and it carries a warranty of 6 months. If it is broken, it has spare parts in Cambodia and repairs are done in the assembly plant of Kamworks in Kandal province. The assembly plant employs young Cambodian technicians as well.

The Cambodian SUN program offers Moonlight as one of its products.    The program is also supporting the development of new solar-powered tools and products and the enhancement of existing products to help in improving the living condition of people in areas where access to electricity is limited.  It is hoped that people even in areas covered by the electric grid will use products like Moonlight and gradually shift to more renewable sources of energy.

Addressing the bane to solar energy promotion


More than thirty people huddled under the house of the village chief to listen to the presentation of the Cambodian SUN marketing staff. Using a flipchart, they discussed the technical aspects of the product and after sales support to the solar home system (SHS). It was fast, within fifteen minutes and the presentation was finished. Question-and-answer portion followed and excited voices asked questions at the same time. The marketing staff patiently answered each question to satisfy the curiosity of the audience.

Surprisingly, the price was not the main concern, but the “cowboys”.  The term refers to the agents selling solar panels house-to-house in the rural areas of Cambodia. They sell solar home systems cheap, as they do not concern with quality of the products. The main approach is “let the buyers beware”.  No after sales service is given. Some promise to provide but when the units break down, nobody comes or the telephone number cannot be accessed.

It is no wonder that most of the questions raised were about customer service.  A specific case shared was the case of a neighbor who bought a unit and after 2 years broke down. Nobody came to repair, and the panel on the roof is a clear testament of an unfulfilled warranty. Another case is a donated set to the school. After several months, the unit was broken and nobody came to repair or maintain it.  Again, the set of three solar panels at the roof of the school reminds the people that it cannot be maintained, and investment to the SHS will be a waste of money. Business practices like these do not contribute in making solar home systems as alternative energy sources in the rural areas. It also deprives the people, especially the poor of cheap, quality and long-term energy source.

One of the main emphases of the Cambodian SUN program is to address the negative effects of cowboy sales.  With the tripartite partnership, the supplier ensures the quality of the product and the after sales customer service; the microfinance institution does not only provide loans but monitoring as well; and, the marketing firm ensures continuous information and education activities to the clients.  It is a good sight to behold that at the end of the marketing session, several people signed up for installation. They will be assessed by the microfinance institution if they are qualified. Once ascertained of their capacity to pay, units will be installed in their houses.

One unexpected result as we leave the village is a cash sale.  While the marketing staffs were answering questions, a lady phoned her children to inform them that she will be buying a solar home system unit. And she paid in cash!



At present, only 24% of the total households in Cambodia have access to electric power. Those outside the main grid are using wood, kerosene and batteries as sources of energy. These energy sources claim a substantial amount on the income of an ordinary household, not to mention its effect on the environment.  Promoting clean energy like solar power is not new to Cambodia. The main reasons to this very low penetration rate are very limited technology information and the cost of the solar home systems (SHS).  People tend to shy away from SHS because of the view that it is expensive and hard to maintain. The cost of ordinary SHS although “cheap” by standard measures is quite high from the perspective of ordinary people, especially those from the rural areas.

Most MFIs are still reluctant to participate in the initiative for the main reason that they have no control over the technology. Break down of low quality SHS units reflect on the MFI which may also lead to high defaults that will eventually affect the bottom line of the institution. Another reason is that adding marketing functions will affect the regular work of the credit staff. MFIs do not want to see the performance of their field staff declining because of the extra efforts diverted to selling SHS.

Thus, what is needed is a three-pronged approach to the problem. First, there should be a technology supplier who will provide SHS unit that is durable, simple to operate, with measures against unintended improper use. The units should have enough stored power for the normal use of a rural household and it should be durable enough to withstand years of continuous use, simple to operate and not expensive. It shall also maintain a team of technical people who will address problems in the SHS unit in a timely manner.

Second, it is necessary to have a marketing company that will conduct education and information campaign to the clients to ensure that they are aware of how to use and maintain SHS. It will maintain marketing and information teams who will go around rural communities doing education campaign. The marketing team will ensure that monitoring is continuously done and feedbacks are collated to improve after-sales service to end-users.

Finally, one of the most important is the financial services provider who will provide loans for those who will acquire SHS units.  The MFIs will be focused in selecting the area for marketing and providing the necessary loan assessment and disbursement services.

The three-pronged approach is expected to capitalize on the strengths of each participating institution.  A program was developed under this approach called Cambodian SUN (Solar energy Unlimited Nationwide).   

Financing for acquisition of SHS under the Cambodia SUN program will be beneficial for the MFI for the following reasons:

  • It can focus on what it does best – lending. Credit officers in the field will not be distracted with non-lending activities since it will be done by the supplier and the marketing and information companies;
  • technical concerns and provision of maintenance will be handled by technical people from the supplier, while education and how-to-use  sessions will be done by the marketing and information institution;
  • the program can be considered as a social goal and a SOCIAL PERFORMANCE MANAGEMENT activity of the MFI;
  • No need to have a new loan product since it can fall under existing individual loans provided by the MFI.

The potential of repeat transaction is there as other solar-based products can be provided for other purposes like enterprises and business activities.

Two main operational features of the Cambodian SUN build up on what where neglected by other suppliers. The first is the definition of a territory. The MFI partner will identify a province where it has substantial number of clients that are potential SHS users. The identification of a territory is necessary to ensure that there will be “critical mass” of clients so that the marketing campaign, the loan processing and the installation will be focused in a defined area. The clients will be adjacent to each other making after sales service more efficient. This will also prevent the MFIs participating in the program from directly competing with each other.

The second is a wide array of customer services that includes the following:

  • guarantee on the most important parts of the SHS;
  • regular maintenance visits of the technician  on the 3rd, 9th and 18th month after installation;
  • 24-hour call center for questions and problems;
  • on-site technical support when the problem cannot be addressed by the call center.
  • conduct of occasional training and education activities on solar and renewable energy
  • collation and processing of feedback from clients

A defined territory and an excellent customer service will provide assurance to the clients that their investment in SHS will really last and they can depend on somebody if ever their units break down.
