Photovoltaic system the outer edge. Electrically connected and mounted on a supporting structure, solar modules build a string of modules, often called solar panel. A solar array consists of one or many such panels. A photovoltaic array, or solar array, is a linked collection of solar modules. The power that one module can produce is seldom enough to meet requirements of a home or a business, so the modules are linked together to form an array. Most PV arrays use an inverter to convert the DC power produced by the modules into alternating current that can power lights, motors, and other loads.
Secure access module Secure access module A Secure Access Module (or Secure Application Module) is based on SmartCard Integrated circuits and is used to enhance the security and cryptography performance in devices, commonly in devices needing to perform secure transactions, such as payment terminals. It can be used for cryptographic computation and secure authentication against smart cards or contactless EMV cards. Physically a SAM card can either be a SIM card and plugged into a SAM slot in a reader, or a fixed integrated circuit in a housing directly soldered on a Printed circuit board (e.g. HVQFN housing). Generally a reader system consists
