Solar energy, a non-polluting source of power generation is widely used in the recent times in many engineering applications. While using this solar energy on the solar panels with a tracking system, the panel gets damaged due to excess radiation. To overcome this problem, in the present work, fins and PCM (Phase Change Material) are used to reduce the temperature of the panel and thereby increases its life. Fins and PCM are attached to the photovoltaic panel and experiments were conducted with fins and PCM and the results are compared without fins and PCM. The experiment is conducted in the following means namely, tracking and without tracking. Besides, the temperature, voltage and current are measured and hence the power output was evaluated. 相似文献

The paper describes a photovoltaic solar generator to supply a dielectric barrier discharge ozone generator employed for water treatment. This paper reports trials of the equipment and modelling the solar power generation system’s efficiency. The design methodology was used to obtain the optimal set point for the orientation of the solar panel during the passage of clouds which causes the decrease of sunlight and thus reduced ozone production. In Algeria, autumn is characterized by the passage of clouds almost every day which negatively affects the performance of the solar panel. The objective of this paper is to identify the set point and to set the robustness of the process in cloudy weather, by determining the optimal values of the orientation angles (north-south and east-west), in order to maximize the power produced by the solar system. Three ‘centred face-composite’ designs were performed on a laboratory experimental set-up and an optimal point was determined. 相似文献

传统的太阳能光伏组件受温度影响较大,光伏组件表面温度的急剧升高会严重影响光伏电池的发电效率。太阳能热电联产系统回收利用太阳能电池产生的热能可降低太阳能电池的工作温度,在提高太阳能电池发电效率的同时亦可产生热水。充分运用热管导热技术,自主设计了热管型太阳能热电联产系统组件、太阳能光热系统。该系统运行两年来,年均产电2.37万k W·h,年产45℃以上热水2 000 t,具有显著的经济和环境效益,推广应用前景广阔。 相似文献

In this paper, a stand-alone photovoltaic (SAPV) power supply system for Microner sprayer is identified and proposed. The designed system was composed of three main parts: sprayer, solar power supply and control system. Initially, the control board and data acquisition system were designed and simulated by the Proteus software and then implemented using an AVR microcontroller and tested via LabVIEW in the laboratory. Next, a prototype system was fabricated for evaluation purposes. A PV panel size of 88.5?cm2, positioned horizontally above operator's head that generates 26.4?Wh/day was used as a solar energy source. A small 2?Ah (12?V) battery is installed in the system as a stabiliser. This sprayer can work seven to nine hours daily. It is calculated that the average loss of collected energy due to non-application of maximum power point tracker was approximately 25%. 相似文献
