Salam,

How are these PVs connected together (series/parallel)?

Are these Amps at peak sunlight?

As per your observation

**Per PV:**

**Power = I x V = 5 Amp x 15 V dc = 75 W** which is half of the rated power of Panel (**150W**). Why is that so?

**Overall:**

**Power = I x V = 20 Amp x 15 V dc = 300 W** which is half of the rated power of system (**300W**). Why is that so?

Jzk in Advance.

i have contacted shopkeper , he say now is winter when summer arrive they will perform better , they are connected in series ..... , half power is due to sunlight in winter is also weak,.
