MGVCL Exam Paper (30-07-2021 Shift 1)
A given solar cell has the following specifications: Open-circuit voltage, Voc: 0.7 V Short-circuit current, Isc: 3.5 A Short-circuit current, Isc: 3.5 A Short-circuit current, Isc: 3.5 A If the solar cell operates at maximum power point, calculate the efficiency.
Let, E→EMF in volt φ→Flux in weber A→Parallel path (for wave winding = 2) Z→No. of armature conductors N→speed in rpm P = Number of poles E = PφNZ/(60A) E = 8*0.020*625/(60*2) E = 500 V
