Abstract
In this study we design and test a novel solar tracking generation system. Moreover, we show that this system could be successfully used as an advanced solar power source to generate power in greenhouses. The system was developed after taking into consideration the geography, climate, and other environmental factors of northeast China. The experimental design of this study included the following steps: (i) the novel solar tracking generation system was measured, and its performance was analyzed; (ii) the system configuration and operation principles were evaluated; (iii) the performance of this power generation system and the solar irradiance were measured according to local time and conditions; (iv) the main factors affecting system performance were analyzed; and (v) the amount of power generated by the solar tracking system was compared with the power generated by fixed solar panels. The experimental results indicated that compared to the power generated by fixed solar panels, the solar tracking system generated about 20% to 25% more power. In addition, the performance of this novel power generating system was found to be closely associated with solar irradiance. Therefore, the solar tracking system provides a new approach to power generation in greenhouses.
Highlights
In recent times, there have been several advancements in greenhouse automation systems [1].These advancements include the creation of artificial light that meets specific light parameters in an internal environment
On 21 December 2012, the power produced by the solar tracking system was 10.94 Wh, while that produced by the fixed panel was only 9.11 Wh
On 21 January 2013, the power generated by the solar tracking system was 17.08 Wh, while that produced by the fixed panel was only
Summary
There have been several advancements in greenhouse automation systems [1]. Researchers are developing alternative energy sources, such as solar photovoltaic panels, which would provide energy for the operation of artificial light in the near future. These alternative energy sources are renewable, clean energy sources that are environmentally friendly. Xiaodi et al [24] have designed a novel solar boiling water system containing a holistic solar funnel concentrator These studies have elucidated how automatic solar tracking systems can be effectively used to address energy problems. We faced energy problems when we provided artificial lighting to greenhouse plants in northeast China during the winter season. We have implemented an improved solar tracking system, which provides a new approach to power generation in greenhouses
