Contribution of refurbishment of solar panels to energy security in South Africa

Abstract

South Africa is currently facing an energy crisis which is affecting businesses and household. As more users install solar panels, some are left behind because the cost of solar panels is beyond their reach. Additionally, as PV installations grow, a challenge of waste management awaits us. This study proposes the refurbishment of used solar panels which can then be re-used, more so by disadvantaged groups in alternative energy access. The study explores the existing refurbishment landscape at an international level, since that is where the practice is happening bringing out its viability, even for small businesses. While it is expected that waste from solar panels will come after their given 25+ years, earlier PV waste generation resulting from early loss/failures is a possibility, providing opportunity for refurbishment. The associated costs and benefits are detailed. The study also explores the refurbishment value chain, identifying business opportunities. It further explores the South African refurbishment landscape, which is not well developed in terms of supporting legislation and standards. Finally, the study outlines international best practices that have enabled refurbishment. It is recommended that South Africa adopts refurbishment, but first the government needs to define legislation around PV waste management and the refurbishment. The practice will not only create jobs but also allow more people to own alternative energy supply sources.
