This excellent PDF document from ABB looks at all the components of solar photovoltaic (solar PV) systems, and explains how the effectiveness and quality of a system are measured by the effectiveness and quality of each single component. Feed-in Tariff examples are provided, along with equipment for direct current system selection, DC string boxes for string protection and isolation, circuit and surge protection devices, and much more besides:
What is commonly called the Balance of System (BoS) - i.e. protection, control and isolation of electromechanical devices and cables - definitely plays a role in ensuring both
an adequate protection of people and of the assets related to the system, and an adequate production of energy over the years. From an economic viewpoint, and even more in comparison with a common electric system, each single component of a photovoltaic system must be chosen above all according to the warranties given by the product and by its manufacturer, because every device must keep its operating
features unchanged throughout the useful life of the system and of the related investment.
This PDF document provides extensive information on all these solar PV topics, and many more, fully illustrated with pictures and examples over 28 pages.
