هذه المحاضرة لسؤال عن اي الالواح افضل في بناء منظومات الطاقة الشسمية؟؟.. وهذا السؤال من الاسئلة الشائعة والمتكررة …فالجميع يريد ان يعرف ما هو افضل لوح شمسي على الاطلاق… في الحقيقة لا توجد اجابة محددة بشكل قاطع… اختيار اي لوح يعتمد على نوع المنظومة المطلوبة وظروف عملها…. والمحددات المفروضة على ذلك، مثل القدرة المطلوبة والطاقة التي تعطيها المنظومة طيلة فترة اشتغالها في ظل الظروف الانوائية مثل درجة الحرارة وظروف موقع نصبها ومحدداته كالمساحة…..
This is the second version of my solar powered model railroad. This runs completely on solar energy using a small solar panel and a specially designed circuit that will allow this train to run on sunny and even overcast days entirely off the grid.
My next version of this will allow this train to run on stored energy for approximately 2 hours without any light. I plan on posting a video once I complete what I expect will be v3.0.
