New monitoring method to characterize individual modules in large photovoltaic systems

Micro Photovoltaic Modules for Micro Systems

Amorphous silicon based solar modules are very attractive for the powering of various microsystems for both indoor and outdoor applications. This technology offers a lot of flexibility in terms of module design, output voltage, shape, size, choice of substrates and offers also the possibility to embed sensors such as photodiodes. This paper focuses on the development of micro-solar modules with...

New method to characterize a machining system: application in turning

Many studies simulates the machining process by using a single degree of freedom springmass sytem to model the tool stiffness, or the workpiece stiffness, or the unit toolworkpiece stiffness in modelings 2D. Others impose the tool action, or use more or less complex modelings of the efforts applied by the tool taking account the tool geometry. Thus, all these models remain two-dimensional or so...

Artist Photovoltaic Modules

In this paper, a full-color photovoltaic (PV) module, called the artist PV module, is developed by laser processes. A full-color image source is printed on the back of a protective glass using an inkjet printer, and a brightened grayscale mask is used to precisely define regions on the module where colors need to be revealed. Artist PV modules with 1.1 ˆ 1.4 m2 area have high a retaining power ...

A new approach to paralleling IGBT modules with individual drivers

Optimization of Auxiliary Power Supply (APS) Systems with Photovoltaic Modules

Auxiliary power supply (APS) systems are increasingly used for low power rating home appliances (e.g. televisions, water dispensers, etc.) and lighting (e.g. CFL lamps) in countries where long power rationing schemes are applied. In general, these systems charge a 240AH (Ampers-Hours) bank of batteries as long as the grid is on and then convert the stored energy into AC current to supply a load...
