Title ABSTRACT
Abstract
Solar cells photoelectric conversion efficiency and panels own temperature inversely proportional to, this paper studies in the sun through the back add water heat exchanger take away heat to reduce solar cell temperature, so as to improve the efficiency of solar cell power generation.
In this paper, the photovoltaic field of the system integration of two main mode: water cooling type and air cooling type system in the park and system model do theory is introduced, and comparison warmth through calculation verified photovoltaic integration system in effectively restrain the sun rise reflected on battery temperature of the advantage. Through the experiment, it is concluded that the sun radiation intensity with the temperature of the battery, time of light, water velocity and the water temperature variations, and drawn with a map.
