%0 Journal Article %T Diffusion of photovoltaic systems for rural electrification in Thailand %A Pranpreya Sriwannawit %A Staffan Laestadius %J International Journal of Energy and Environment %D 2013 %I International Energy and Environment Foundation (IEEF) %X This paper studies a pilot project in which photovoltaic systems were installed in thirty-six places in the remote areas of Thailand with no access to electricity. One sub-project out of thirty-six was chosen for in-depth investigation. We discuss the appropriateness of solar energy for Thailand context. The diffusion process of PV systems is analyzed on four elements: innovation, communication channel, time and social system. This project is an extreme case as the PV systems and services were provided for free of charge. Even so, there are still some challenges to get acceptance for this sustainable form of energy. %K Diffusion of innovation %K Innovation %K Photovoltaic %K Rural %K Thailand %U http://www.ijee.ieefoundation.org/vol4/issue1/IJEE_04_v4n1.pdf
