    With lots of sunshine and an underdeveloped electrical grid, Cambodia is well suited to solar power.
    But overcoming challenges like poverty and a lack of solar knowledge are major challenges.
    STORYLINE
    The power of the sun could be the key to provide energy in rural areas of Cambodia.
    Social enterprise Kamworks brings solar energy to the population cut off from the national grid.
    Kamworks is based in the rural Kandal province about 50 kilometres (31.1 miles) north of the capital Phnom Penh.
    Set up by Dutchman Arjen Luxwoldawas, the company was established in Cambodia in 2006.
    Kamworks was funded through a World Bank project.
    The enterprise develops and manufactures solar energy devices including systems for water pumping, electricity, and refrigeration.
    Their products are sold to homes and businesses all over Cambodia as well as in Thailand, Vietnam and Laos.
    Chief Operating Officer Brecht Van Der Laan says tropical Cambodia is an ideal country for solar power.
    “First of all, of course, because there’s a lot of sun. Second of all because seventy-five percent of the country is not connected to the grid, which is about eighty percent of the population. Therefore instead of making expensive electric grids it’s really cost efficient to start solar here,” he says.
    Kamworks’ signature product is the MoonLight solar lantern which was designed in collaboration with villagers.
    The device fits the needs of the rural poor who need lighting to ride their motorbikes, brighten their houses, and move about in the dark in the countryside, according to Sokun San, head foreman at Kamworks.
    “You can charge the battery during the day with the solar panel and use it at night just like a regular lamp. You can hang it around your neck and use it like a torch or you can hang it like this and use it as a light in your house,” explains Sokun San.
    Kamworks assembles all their systems locally.
    Its aim is to bring technology, jobs and expertise in the country.
    This allows the company to better service their products which can be easily recycled at the end of their lifetime.
    To help distribute the solar systems – and teach people how to use them, Kamworks works closely with the Dutch NGO Picosol set up in 2008.
    Picosol Cambodia Country Manager Yolanda Zwetsloot says that expanding solar power usage in the country is challenging.
    “There are some problems in Cambodia. One problem is the lack of knowledge, the second problem is that there are long distances to cover and the third problem is they don’t have the money to buy it so with these problems we want to help companies and we want to help villagers to solve these issues and that’s why we’re here,” she says.
    Picosol built this training house where Cambodian villagers learn how to install and use solar devices.
    The training is free of charge and the knowledge can later be shared with others who are considering to switch to solar power.
    Solar power is perfectly suited to rural families says Brecht Van Der Laan.
    “The benefits of solar for the rural people is that it’s safe – a lot of people use kerosene lights and there’s a big fire risk in that. It’s also more convenient because you don’t have to drag around car batteries from here to there and of course because it’s cheaper in the end,” says Van Der Laan.
    In the last five months, Kamworks has installed over 12,000 solar home systems across 7 provinces in Cambodia.
    For Keat Kalyan, living in the Sre Ampil village, the Moonlight lamp made her life easier.
    Kamworks is planning to export solar devices to ten countries in Africa and Asia by the end of 2013.
