Thailand is a developing country that is often cited for its success story of on-grid electrification. This success of on-grid electrification is mostly due to the Thai government’s commitment to provide electricity to every Thai citizen. In 1971, the government began a huge initiative to provide electricity in rural areas, mostly through grid extension, but also through some off-grid Photovoltaic projects, such as solar battery charging stations. In 1974, the estimated percentage of electrified villages was 20%. By 2002, 99% of the households in Thailand were electrified. The estimated number of un-electrified households in Thailand in 2002 was about 440,716. It is widely believed that Photovoltaic technology will be useful in electrifying these remaining remote villages
