المدخرات عبارة عن أجهزة تستخدم لتخزين الطاقة و بشكل خاص لإمداد الأجهزة الكهربائية الصغيرة و المحمولة مثل أجهزة الخليوي و الكومبيوتر المحمول و الأجهزة الترفيهية في المركبات التي تسير على الأرض أو في الهواء أو الماء، و تأتي أهمية المدخرات في نظم الطاقة الكهروشمسية بإمدادها الأحمال بالطاقة الكهربائية اللازمة في أثناء الليل و في فترات الإشعاع الشمسي القليل مما يؤمن استمرارية التغذية الكهربائية من جهة و رفع وثوقية النظام من جهة أخرى.
Batteries are energy storage devices that are particularly useful for powering
small portable devices like phones, laptops and entertainment devices as well as
mobility devices that travel over the earth's surface, through water and air. During the
night, or during a period of low solar irradiation, energy is supplied to the load from
the battery in solar electrical Power Systems, and that provides Continuity of power
supply, and on the other hand boosts the Reliability of the system.
