The output power capacity of solar panels depends on the intensity of light radiation it receives, while the life time depends on the high and low temperatures experienced. The purpose of this study was to examine the effect of light intensity on the output power and efficiency of solar panels. This study applies a direct measurement method using a monocrystalline type solar panel and a polycrystalline type with the same power capacity with a peak capacity of 50 Wp. The research was conducted indoors using lights as light sources by varying the light intensity in the range 2.21-331.01 W/m2 with a distance of 50 cm from the light source from the solar panel. The increase in temperature on the surface of the solar panel can also reduce the power capacity generated, and the monocrystalline type is more resistant to temperature increases than polycrystalline. The efficiency of the solar panel changes when given light with a certain energy, up to the highest intensity of 331.01 W/ m2, with the highest temperature that occurs resulting in an efficiency of 12.84% on the Monocrystalline Panel and 11.95% on the Polycrystalline Panel.

Solar cell is a device that converts photons into electricity. The performance of a solar cell depends on its efficiency. The efficiency of a solar cell depends on some atmospheric variables such as light intensity, temperature, pressure, wind, humidity, precipitation and the sky condition etc. Geographical locations are the main factor for the variation of atmospheric variables. Due to atmospheric variables the solar cell efficiency is not same for all places of the World. Solar cell has been analyzed from different approach to improve its efficiency. The objective of this research is to analyze the efficiency of a silicon solar panel at three different places: Chittagong University Campus, Sandwip Island and Shibpur thana of Narshingdi district of Bangladesh. The efficiency mostly depends on the light intensity and temperature, however slightly depends on humidity. The experimental study shows that among the three places Norshingdi district is more suitable for solar power with the efficiency of 16.25% than other two places, where the efficiencies are 15.7% at Chittagong University Campus and 15.83% at Sandwip Island.Journal of Bangladesh Academy of Sciences, Vol. 42, No. 1, 99-104, 2018

In this paper, we propose a conceptual design to reduce the solar power plant area by using dish reflector and solar panel arrangement by placing the solar panel at 90° angle. The solar rays get redirected into the box with the help of parabolic dish reflectors which results reduced size requirement for the panel installation. The reflective surface increases both light intensity as well as power generation by the solar panel. Also, the usual factors associated with general installation method like dust or snow formation and bird dropping over the panels that affect the efficiency of solar panels are avoided in this light box concept.

Photovoltaic cells are converts about 15% of the solar energy falling into the useful electricity. The increase in the temperature increases the resistance of these cell and in turns decreases the cell efficiency. So, cooling these panels is the effective way of increasing the cell efficiency. The performance of the solar panel increases by reducing the temperature. This cooling is done by air cooling or water cooling on the self-designed modified panel. The solar panels are cooled by passing air with the help of blower.

Power Point

Maximum Power Point Tracking (MPPT) is a method that can be used to optimize the electrical power output from solar panels. The performance of the MPPT method on solar panel systems can be influenced by many variables. One of them is the selection of a DC-DC power converter. DC-DC-DC Converter is a component that is used to optimize the performance of solar panels. Several types of DC-DC Converter are Buck, Buck-Boost, Single Ended Primary Inductance Converter (SEPIC), and CUK. Each converter has a different effect on solar panels output power. In order to observe and make a comprehensive analysis, simulations are performed through PSIM (Power Simulator) software on the performance of several DC-DC Converters that use Flower Pollination Algorithm (FPA) as the MPPT algorithm. Variables that observed are the output power characteristic, the response of the voltage-current ripple signal, and the accuracy of the converter in the process of reaching the maximum power point condition. As a result, CUK converter can obtain the highest value of solar panel output power, 145.02 W. A low ripple level with a stable power value response is entirely generated by CUK and SEPIC Converter. Overall, for this system, the CUK converter has better performance than the other converters.

ABSTRACTCurrently, organic photovoltaics are not a viable renewable source of energy in comparison to silicon solar panels because of its low efficiencies, due to its disorganized morphology which leads to charge recombination and an overall loss of energy production. It was hypothesized that simultaneously organizing the morphology and increasing the area of the active sites for exciton dissociation would improve overall efficiency.Our synthesized gold-graphene (AuRGO) was dispersed in sulfonated polystyrene (PSS) and added to the active layer. We also blended polymethylmethacrylate (PMMA) with graphene, which was then incorporated into the active layer. AFM imaging demonstrated that the polymers self-assembled into column structures. Additionally, the AuRGO showed an affinity for both P3HT and the PSS, migrating to the interfaces. Solar simulation results show that both polymer-graphene blends demonstrated enhanced current and efficiency.The self-organization helped increase the efficiency of both samples, but the AuRGO/PSS had a greater efficiency improvement over the cG/PMMA by 170%. This increase is attributed to the fact that since the AuRGO migrated to the interfaces, the sheet acts as a bridge that improved the electron flow through a connection between the electron donating and accepting materials, improving exciton dissociation and charge transport, and therefore efficiency.

The output power of the photovoltaic battery array of a solar parking garage is affected by two factors of arranging form and external conditions. Firstly, a solar parking garage in Qingdao is taken as an example. A simulation model of its solar panel square is established based on Matlab/S-Fcn/Simulink. The GX-120 solar panel with the size of 1250mm×808mm is taken as an example. And the normal external conditions and the principle of maximum output power in one year are also considered. Simulation results based on Matlab/S-Fcn/Simulink demonstrate that solar panels should be put on the dip angle of 30，with the span of 1605mm between two row. 28 solar panels can be arranged on the top of the parking space. Secondly, an experiment setup is established in order to simulate the electricity generating process by solar panels and parking process. Two GX-120 solar panels are employed as power generation device, while two 12V, 195AH storage batteries are employed as energy storage device. A direct 24V electromotor with hydromantic pressure 18MPa device is applied as simulation load, which can demonstrate the ascending and descending process in the parking space. The experiment studies the performance of the solar panels under different weather conditions. Results show that generating capacity of two pieces of panels can make a parking unit work eleven times, five times, one time and six times separately under four kinds of weather conditions (sunny, cloudy, rainy, and foggy day). The energy matching principle is that the parking lot only can provide 6.85 kilowatt for electric vehicles one day in the condition that each parking space parks cars four times every day in order to meet the continuous use of the parking garage. The rest of electricity must be storied in the battery.
