The ouput power of solar panel that decreased due to shading has been improved using bypass diode method. The placement of bypass diodes increased the output current and power. New peaks and maximum powerpoints on the current-svoltage characteristics and power-voltage characteristics were observed. Without bypass diodes, the maximum output power was only around 50 W. After placing bypass diodes, the first peak around 115 W and second peak around 150 W appeared at voltage of around 31 V and 40 V, respectively.

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.

In applications with low-energy conversion efficiency, maximizing the output power improves the efficiency. The maximum output power of a solar panel depends on the environmental conditions and load profile. In this paper, a method based on simultaneous use of two fuzzy controllers is developed in order to maximize the generated output power of a solar panel in a photovoltaic system: fuzzy-based sun tracking and maximum power point tracking. The sun tracking is performed by changing the solar panel orientation in horizontal and vertical directions by two DC motors properly designed. A DC-DC converter is employed to track the solar panel maximum power point. In addition, the proposed system has the capability of the extraction of solar panelI-Vcurves. Experimental results present that the proposed fuzzy techniques result in increasing of power delivery from the solar panel, causing a reduction in size, weight, and cost of solar panels in photovoltaic systems.

ABSTRACT The purpose of this research is to increase the power output of the solar panels and to know the effect on the solar panel after adding a converging lens and a diverging treatment varying distances and angles. The hypothesis of this study is anticipated to the influence of the use of a diverging lens and converges to the power output of solar panels. This study used an experimental method with quantitative approach. The subjects of the study were used that kind of Polycrystalline solar panels. Data analysis technique used is descriptive analysis with data collection techniques are observation laboratory and field observations. The conclusion of this study is to raise the value of the output power on solar panels can use a converging lens. This is evidenced by the results of the testing are the biggest increase in the converging lens use solar panels to power 900 outputs the angle and the distance between the lens and solar panels with a power output of 25 cm measured 56.46 μW. The influence of the use of a converging lens located on the corner of 150 and the distance between the lens and the solar panel 21 cm with an increase of 203.64%. These values occurred as a converging lens can focus the light so that the intensity of the light falling on the solar panels increases. While the greatest influence use of a diverging lens located on the corner of 300 and the distance between the lens and solar panels 1 cm with a decrease of 63.96%. These values occurred as a diverging lens can refract light so that the intensity of the light falling on the solar panel decreases.   ABSTRAK Tujuan penelitian ini yaitu untuk meningkatkan daya keluaran pada panel surya dan untuk mengetahui perbedaan pengaruh pada panel surya setelah ditambahkan lensa konvergen serta divergen dengan perlakuan jarak dan sudut yang bervariasi. Hipotesis penelitian ini yaitu diduga adanya pengaruh dari penggunaan lensa divergen dan konvergen terhadap daya keluaran panel surya. Penelitian ini menggunakan metode eksperimen dengan pendekatan kuantitatif. Subyek penelitian yang digunakan yaitu panel surya jenis Polycrystalline. Teknik analisis data yang digunakan yaitu analisis deskriptif dengan teknik pengumpulan data yaitu observasi laboratorium dan observasi lapangan. Kesimpulan dari penelitian ini yaitu Untuk menaikan nilai daya keluaran pada panel surya dapat menggunakan lensa konvergen. Hal ini dibuktikan dengan hasil pengujian terdapat kenaikan terbesar penggunaan lensa konvergen pada panel surya terhadap daya keluaran yaitu sudut 900 dan jarak antara lensa dan panel surya 25 cm dengan daya keluaran yang terukur 56,46 µW.Pengaruh terbesar penggunaan lensa konvergen terdapat pada sudut 150 dan jarak antara lensa dan panel surya 21 cm dengan kenaikan sebesar 203,64%. Nilai tersebut terjadi karena lensa konvergen dapat memusatkan cahaya sehingga intensitas cahaya yang jatuh pada panel surya meningkat. Sedangkan pengaruh terbesar penggunaan lensa divergen terdapat pada sudut 300 dan jarak antara lensa dan panel surya 1 cm dengan penurunan sebesar 63,96%. Nilai tersebut terjadi karena lensa divergen dapat membiaskan cahaya sehingga intensitas cahaya yang jatuh pada panel surya menurun. jatuh pada panel surya menurun.
