This paper will describe some of the problems that arise when attempting to charge secondary storage batteries, of the lead-acid type, from an energy source such as a photovoltaic array. A description of the means generally used to charge a lead-acid. battery in a standard photovoltaic system is given, and a proposed series regulator "smart" type system which may be used to improve battery...
Photovoltaics, as a compliment source of power for telecommunication applications, has been recently widely accepted. Photovoltaic modules consisting of silicon solar cells connected in series or parallel, provide on site, the required charging current for the batteries, thus enabling maintenance free operation and reduced storage costs for the total system. Flat plate solar panels are presently operating...
The design of solar photovoltaic systems can now take advantage of improved sources of sunshine data. Use of this data with proper computer programs allows the system designer to optimize the design for lowest cost while being able to demonstrate the resulting system reliability. At the present time, additional types of photovoltaic devices are appearing on the market made by advanced thin film techniques...
Telettra, a private company of the FIAT group operating in telecommunications, designed and is about to finish the installation of a high capacity, line-of-sight radio link over the Red Sea, i.e. between Saudi Arabia and Sudan. The study, design and construction of long over-sea's microwave links have been a traditional part of Telettra's activity for the last 25 years. The design in question is based...
