“…By utilizing a Raspberry Pi with a webcam, it is possible to track the location of the sun in the sky using an algorithm to take snapshots of the sky or of a bar shadow [19] and contrast them and rotate the platform accordingly [20] and [21]. The cost of this approach is in-line with the method in 3.1, although this technique has the advantage of being well documented and tested.…”

Abstract:Comparison of Comparison of Solar Power System (CSP) power plants will be introduced and discussed; Solar Tower (ST) plants and Parabolic Trough (PT) plants are subjects of this comparison. The comparison will be made possibly analytical or quantitatively instead of qualitatively. Examples will be presented and explained in detail. The main issues such efficiency, area of the plant, environmental issues, molten salt storage, the cost of the plants, dust and humidity, maintenance and operation cost and total investment are discussed.

Nonpolluting, renewable energy can be harnessed from the sun using solar thermal concentrator and photovoltaic systems. A novel asymmetric oblique compound conical solar concentrator was designed and constructed with automatic solar tracking system. The experimental study of the developed system was carried out to inspect the efficiency of the designed solar concentrator and automatic azimuth and altitude tracking. In this solar tracking, the RTC (Real Time clock) based active solar tracking method is used to track the sun in order to attain the maximum temperature. A simple microcontroller based control system is used to control this open loop solar tracking system, further the concentrated thermal power was measured using both the K-type temperature sensor and thermometer gun. The temperature obtained at the receiver of solar concentrator is sent to the measurement unit using GSM wireless module available at remote location. The monitoring unit receives the temperature values and recoded them regularly. Besides, the maximum average solar thermal power of the system was observed to be during 10.00 AM to 3.00 PM. This temperature is useful for various heating applications.

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% OPEN ACCESSEnergies 2015, 8 7368 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.
