Issues in PV systems applied to rural electrification in Brazil.

In Brazil, the access to electricity is a right of all their citizens. The Brazilian government has endeavored to extend the electric grid wherever technically and economically feasible. For the remaining sites, PV systems can be a feasible option that is enforced by federal laws, standards and subsidies. For this reason, unlike other countries where renewable energy systems are donated or commercialized by NGOs and other entities, in Brazil these systems are mainly installed by utilities, making the country a unique case for study. This paper analyzes the main problems faced by PV systems for rural electrification. The methodology is based on field observation and literature survey. As a result, several issues of demand to be supplied, installation, operation and maintenance, and post-installation were identified. From these observations, it is clear that a greater attention should be payed to the management of the whole electrification project, by clearly delimiting the goals and the responsibilities of each stakeholder, and ensuring that the goals are met.
