Field Experiences and Lessons Learned with Photovoltaic Off-Grid and On-Grid Applications in Northern Chile
Abstract
Summary Due to the high solar energy radiation in northern Chile photovoltaic systems for electrical energy supply in off-grid and on-grid applications present attractive energy solutions under technical and economic aspects. Field experiences made within the last 20 years in different projects in small scale applications up to 35 kWp are shown with focus on project planning, design, reliability of components, capacity building and necessary support after installation. In general, a very high acceptance for renewable energy projects can be observed on all levels, from users up to regional and national decision makers, but the number of installations especially in the private sector is relatively low. Main obstacles for a wider dissemination are discussed concentrating on financial topics such as investment costs and access to reliable and appropriate information for users.
