A low cost shading analyzer and site evaluator design to determine solar power system installation area

Shading analyzer systems are necessary for selecting the most suitable installation site to sustain enough solar power. Afterwards, changes in solar data throughout the year must be evaluated along with the identification of obstructions surrounding the installation site in order to analyze shading effects on productivity of the solar power system. In this study, the shading analysis tools are introduced briefly, and a new and different device is developed and explained to analyze shading effect of the environmental obstruction on the site on which the solar power system will be established. Thus, exposure duration of the PV panels to the sunlight can be measured effectively. The device is explained with an application on the installation area selected as a pilot site, Denizli, in Turkey. © 2015 Selami Kesler et al

Computer aided Eprom programmer

Bu çalışmada, EPROM ve programlanması anlatılmıştır. Hafızalar hakkında kısa bir temel bilgi verildikten sonra Z.80A PIO ve RE 350 giriş-çıkış portu (dış-açılma birimi) ile ilgili donanım ve yazılım üzerinde durulmuştur. Bundan sonra asıl EPROM programlayıcı devre gerçekleştirilmiştir. Programlama dili olarak, ZX Spectrum ve RE 350 G/Ç portu ile uyumlu BASIC kullanılmıştır. Son olarak cihazın işletimine ait programlar yazılmıştır.In this report, EPROM and its programming have been studied. After giving a basic knowledge on memories, the hardware and software concerning the Z.80A PIO and the RE 350 I/0 port have been given. The programming language used on the study is the BASIC being compatible with the ZX Spectrum and the RE 350 port. Finally, the operation programs of the set have been written aut
