The use of decentralised renewable energy technologies to provide rural electrification in developing countries has been a common
topic of analysis and policy debate for more than two decades. Unfortunately, a lack of empirical evidence about the field
performance of these technologies is a significant barrier to making sound policy decisions about them. Compounded by minimal
information sharing between stakeholders, this situation has frequently allowed duplication of inefficient policies. This issue is
addressed here by providing empirical evidence gathered from field visits and interviews about the largest government subsidised
solar battery charging programme in the world. This analysis highlights the different policies of departments responsible and
discusses them with specific attention to their technical, social and economic components. Field study results from over 50 villages in
the north of Thailand suggest about 60 per cent of these systems are no longer operational. Many of the technical failures observed
are attributed to social factors, as well as flawed implementation strategies.
