المشروع : مقارنة الجدوى الاقتصادية لمنظومة خلايا شمسية قدرة 1كيلووات تعمل في مدن مختلفة ( غزة , الاسكندرية , الرياض , اثينا , لندن )
منظومة الطاقة تلك عبارة عن محطة خلايا شمسية بقدرة اسمية 1كيلووات ( القدرة الاسمية : قدرة المحطة تحت ظروف المختبر) , الجدول التالي يوضح مقارنة بيانات نفس الوحدة في محيط مدن مختلفة
| المدينة | الانتاج السنوي
كيلووات/سنة | اقصى انتاج شهري
كيلووات/الشهر | اقل انتاج شهري
كيلووات/الشهر | متوسطالاشعاع الشمسي اليومي
كيلووات/المتر المربع |
| غزة | 1630 | 162 ( يوليو ) | 96.7 (ديسمبر) | 6.02 |
| الاسكندرية | 1640 | 164 ( يوليو) | 98.2 ( ديسمبر ) | 6.18 |
| الرياض | 1560 | 139 (اغسطس) | 122 ( يناير ) | 6.05 |
| اثينا | 1320 | 146 (يوليو ) | 64.7 (دسسمبر) | 4.86 |
| لندن | 875 | 111 (يوليو) | 22.4 (ديسمبر) | 3.06 |
من الجدول لاحظ التالي :
- يمكن اعتبار عمر منظومة الطاقة = 25 سنة من الانتاج بطاقة كاملة ... هذا الرقم كي تكمل حساباتك
- انتاج المنظومة في المدن العربة يقترب من ضعفها في لندن حيث تشجع الحكومة مواطنيها وتدعمهم لانشاء مثل تلك المنظومات
- الفرق بين انتاجية اقل شهر في السنة واعلى شهر قليلة جدا ( وخاصة الرياض) مما يعني الاستمرارية ومناسبة عملية التخزين في حالة ان تكون المنظومة غير متصلة بالشبكة العامة
- مما سبق ... اضغطوا على حكوماتكم لتسمح بربط منظومات الطاقة المتجددة بالشبكات العامة لان الاستثمار في الطاقة الشمسية ذا جدوى عظيمة ومتاح لكل المستويات
- المعلومات في الجداول التالية مأخوذة من البرناج الذي يستعملة مصمموا منظومات الخلايا الشمسية في اوروبا وافريقيا والشرق الاوسط
- بيانات البرنامج تعلمنا ان مستقبل الطاقة الشمسية في منطقتنا هو امتداد لحاضر النفط من جهه الاهتمام العالمي بمنطقتنا .
- اسعار الخلايا الشمسية في هبوط مستمر حيث وصلت الى 0.7$/وات... اي ان تكلفة اكيلووات=700 دولار امريكي ... وهي في هبوط متصل .
المعلومات من الموقع http://re.jrc.ec.europa.eu/pvgis/apps4/pvest.php?map=africa يمكنك من حساب طاقة الخلايا الشمسية لاي موقع في الخريطة ... حدد الموقع اولا ... ثم اكمل البيانات ... ثم انقر ... احسب (calculate )
وفيما يلي امثلة لتطبيقات البرنامج
