Solar Power System

Solar panels, capture sunlight as a source of radiant energy, which we currently receive in the form of DC power which is converted to AC energy by using an AC to DC inverter. सौर पैनल सूर्य के प्रकाश को उज्ज्वल ऊर्जा के स्रोत के रूप में ग्रहण करते हैं, जो वर्तमान में DC बिजली के रूप में बिजली प्राप्त होती हैं। जिसे AC to DC  इन्वर्टर लगाकर AC ऊर्जा में परिवर्तित किया जाता है।
