This section aims to provide you with state-of-the-art basic knowledge and understanding of photovoltaic power systems particularly those systems which are grid-connected distributed.

The questions and answers in this section cover:

• Technical aspects: photovoltaic power systems, system elements and applications.

• Economical aspects: prices, costs, etc. and commercial aspects (guarantees, etc.), added values to the use of photovoltaic power systems.

• Environmental aspects: environmental impacts in the process of manufacturing, in the process of daily use, when decommissioning, etc.

• Social aspects: Impact on social development, etc.

• Other aspects.

Please check the glossary for an explanation of the terms, abbreviations and definitions used. For information about the working principles of photovoltaic cells and photovoltaic modules, we refer to the section Basics of PV.
