Abstract

Photovoltaic technology has been widely studied as one of the most promising new energy technologies around the world. The critical problem is, however, low conversion efficiency has hindered its development. This paper has analyzed effective factors to conversion efficiency in photovoltaic power system at first, and elaborated the way how these factors work simultaneously. Then, three typical methods including Constant Voltage (CV), Incremental Conductance (IC) and Perturbation & Observation (P&O) of maximum power point tracking (MPPT) have been summarized and concluded its characteristics application scope at the same time. Lastly, this paper has proposed a method by integrating Constant Voltage (CV) and Incremental Conductance (IC) to keep track of the maximum power point precisely and quickly.
