Dalam proses pengisian aki (charging) dengan sumber listrik yang berasal dari solar cell,tentunya diperlukan sebuah alat kontrol yang berfungsi mengatur sistem pengisian energi listrikyang biasa disebut solar charge controller atau kontrol pengisian. Pada aplikasinya, adakalanyapenggunaan alat kontrol pengisian tersebut masih terdapat kekurangan, diantaranya ialah alattersebut hanya dapat digunakan untuk pengisian aki dengan tegangan 12 dan 24 volt saja. Sehinggajika digunakan untuk tegangan yang lebih tinggi dari itu, maka diperlukan modifikasi sistempengisian yang sesuai dengan kebutuhan untuk menganalisa arus konstan yang dihasilkan, untuk itudigunakan dual tracking solar cell sebagai sumber charging sistem aki sehingga didapatkan sistempengisian aki yang efisien. Sistem yang digunakan kita sebut dengan sequence method, yaitupengisian dengan cara bergantian satu persatu sampai kondisi kapasitas aki penuh dengan caramengontrol alat yang telah diprogram untuk bekerja dengan cara memaksimumkan output arus yangdi peroleh dari pergerakan solar panel mengikuti sudut azimuth dan altitude dari matahari. Tujuanyang ingin dicapai dari penelitian ini adalah pencapaian arus yang konstan dengan rate 0.1A denganmemaksimalkan pergerakan solar panel mengikuti pergerakan arah matahari.

Solar Home System

In part II of this series, it was reported that the solar home system (SHS) supplied by REB in some islands of the Meghna river in the district of Narsingdi could not meet the demand of the recipients in the rainy season when the sky remained overcast with cloud. The tilt angle for all installations was 45° facing south. In this study, effects of direct and diffuse sunlight with variation of tilt angles from 0° to 45° were studied using a mono crystalline silicon cell. Pyranometer and the solar panel were kept under identical conditions. Energy absorbed by the solar panel in diffuse sunlight was found 0.55% of that received by the Pyranometer under similar conditions showing that mono crystalline silicon solar cell of the type under study was not suitable for use in SHS. Moreover, the gap between the panel and the solid surface below it has significant effects on the efficiency of the solar cell. Further similar study using different kinds of cells- mono crystalline, poly crystalline and amorphous is needed for proper designs of SHS. Optimization of the gap between the panel and the solid surface below it is important for roof-mounted and ground-mounted panels.

Lighting is an essential thing in performing daily activities and without sufficient lighting we will be difficult to see clearly. The problem is when there is no electricity, for example when we go to a cave or a forest or when there is a natural disaster that shuts down all the electricity. A portable lamp that can be charged by exposing the lamp to sun light can be one of the solution to overcome this problem. Energy Harvesting is a concept where an energy is captured, stored, and used with several technologies including solar technology. Energy Harvesting technology is used in many applications such as calculator, electrical cars or day-to-day lighting This paper will discuss about an application of solar panel in portable LED lamp, that can be used in the night and can be charged during daytime with solar panel. The solar panel, LED, and the battery is integrated in one circuit so there will be more space convenient for user. Solar emergency lamp can be used to illuminate the pathway in mountain or caves and the lamp can float in the water because it case is inflatable. Rechargeable Li-ion Battery 3.7 V 500 mAh and 10 LED SMD is used in this lamp. The proposed design is using a transparent PVC for the case of the lamp. The lamp can be turned on approximately for 4 hours from fully charged battery with 10 LED lamp. The illumination of solar portable emergency lamp was measured using lux meter. The illumination average of the solar portable emergency lamp is 17.58 lux with a deviation of 7.3 lux with medium bright mode. The illumination average of the solar portable emergency lamp is 32.85 lux with a deviation of 12.4 lux for the full bright mode. The Illumination is measured in 50 cm below the solar portable emergency lamp with 9 measured point consisting of 3 rows and 3 columns.

The Cost

The cumulative installed solar power generation has been rising exponentially over the past decade. This has lead to a concomitant rise in production capabilities, leading eventually to excess production capabilities and rapid price declines per unit. In order to compete with the standard electricity generation the cost of solar panel production and installation needs to decrease even further. At the same time the solar panel and cell makers need to be able to keep a healthy margin. A crucial element in this exercise is a close control on the Cost of Ownership (CoO) of a solar cell / panel fabrication site.

In this paper a motorized solar energy collector system-a driver system that positioned the solar cell panel differently during day-time was design and implemented. The aim is to optimize the amount of solar energy that can be trapped from the sun using a solar cell panel. This is achieved by using a stepper motor, controlled by Atmel AT89C52 microcontroller, to align the panel such that all incident rays strike normal to the panel’s surface thereby maximizing the amount of solar energy that can be trapped from the sun. The alignment is time dependant. This model was implemented and tested and the results proved to be successful in maximizing the energy received from the sun than if the solar panel was fixed at a particular position.

Permasalahan utama dari solar cell adalah perbedaan jenis solar cell yang mengakibatkan perbedaan kinerja pada solar cell tersebut. Besarnya daya keluaran yang dihasilkan relatif tidak konstan karena dipengaruhi oleh besarnya intensitas matahari  serta  suhu  lingkungan  di  sekitarnya.  Untuk mengatasi masalah tersebut maka tugas akhir ini dirancang untuk melakukan perbandingan panel surya monocrystalline jenis vertikal dan jenis fleksibel.Pada hasil pengujian dengan pencahayaan matahari panel surya fleksibel menghasilkan efisiensi lebih tinggi dibanding dengan panel surya vertikal, yaitu 20,8774%, sedangkan panel surya vertikal meghasilkan efisiensi sebesar 19,2844%. Dalam penggunaan simulasi pencahayaan lampu panel surya vertikal menghasilkan efisiensi yang cukup tinggi dan lebih tinggi dibanding panel surya fleksibel, yaitu 20,4818% sedangkan panel surya fleksibel menghasilkan efisiensi sebesar 16,4044%. Pada panel surya fleksibel dengan bentuk cembung 25° menghasilkan efisiensi sebesar 15,3200. Pada bentuk cekung 25° menghasilkan efisiensi 15,6265%.The main problem with solar cells is the different types of solar cells that result in differences in the performance of the solar cell. The amount of output power produced is relatively not constant because it is influenced by the intensity of the sun and the temperature of the surrounding environment. To overcome this problem, this final project is designed to compare the vertical and flexible monocrystalline solar panels. In the test results with solar lighting, flexible solar panels produce higher efficiency than vertical solar panels, which is 20.8774%, while vertical solar panels resulted in an efficiency of 19.2844%. In the use of simulated lighting, vertical solar panel lights produce high and higher efficiency than flexible solar panels, namely 20.4818%, while flexible solar panels produce an efficiency of 16.4044%. In a flexible solar panel with a convex shape of 25° it produces an efficiency of 15.3200. In the concave shape of 25° it produces an efficiency of 15.6265%.

Solar power is future of our planet due to the depletion of non-renewable sources of energy. The renewable sources of energy are responsible for 80% of world’s power and we all are directly dependent on non-renewable source which will only last for 1 or 2 decades. Due to increase in power demands new development in renewable sources of energy are going on due to which on commercial level solar cell achieved an efficiency of 15-20% and improving day by day. Some factors affects the performance of solar panel and decreases its output while some factors improves the efficiency of solar cell and improves its performance. These factors includes temperature of solar panel, humidity, and wind velocity, light intensity, altitude and air pressure along with many other factors. In this paper these factors are discussed along with their impact on solar cell performance
