Abstract

Aiming at the hot spot effect of PV（photovoltaic） series, this paper studies the suppressing strategies of hot spot of PV series. Firstly, the existing hot spot suppressing strategies of PV series are summarized and compared from the aspects of suppressing cost, power loss, hot spot temperature and output power, and an evaluation method of hot spot suppressing strategies is given. Then, a new hot spot suppressing strategy is proposed by using serial resistance. The designed circuit of the proposed strategy consists of voltage comparator, MOSFET, triode, voltage divider, and the principle are analyzed. Finally, the effectiveness of the suppressing strategy is verified by simulation and experiment. Comparing with the traditional solutions, the proposed hot spot suppressing strategy has the advantages of low temperature and large output power of hot spot cells.
