Solar-radiation components, namely global, diffuse and direct, were calculated over the Syrian landmass using several mathematical equations starting from the Angström formula. An appropriate theoretical method and a computer program were specially designed and developed for these calculations....

This paper presents a Sun-tracking design, whereby the movement of a photo-voltaic module was controlled to follow the Sun's radiation using a programmable logic-controller (PLC) unit. All electronic circuits and the necessary software have been designed and developed to perform the technical...
