Solar energy has been developed in wide areas because its potential to replace the current classic energy, fossil fuel. The advantages of solar energy are cheap and clean. To generate solar energy, photovoltaic is used. There are some factors affects the performance of photovoltaic. Some of them are the amount of light beam received and temperature of photovoltaic surface. This research was done to get better understanding of the factors on the photovoltaic performance. In order to reach the goal, two different solar reflector areas and wind velocity were applied. The wind source is coming from a blower while solar reflector was made from glass. The results showed that the watt peak, power point power maximum (PMPP), and output efficiency were increased by application of larger solar reflector and high wind velocity. Larger reflector application resulted in sun light can be focused directly to the solar panel therefore increasing the watt peak. Meanwhile, higher wind speed on the solar panel surface can reduce the solar panel surface temperature which lead to the improvement in maximum output efficiency.

Aiming at the low generating efficiency of the current solar energy generating system, solar energy maximum power point tracking control system based on STC89C52 is designed and made. The photoelectric detection and tracking is adopted as the control mode in the system. By using stepping motor as driving mechanism, comprehensive trace of the sun is realized by controlling the movement of tracking mechanism in the horizontal and pitching directions. Based on this, real-time detection of wind velocity and change of wind direction is realized by wind velocity and direction transducer which is equipped on the tracking mechanism, which makes the system automatically avoid the typhoon above level 8 to weaken the damage to panel by the storm. The experiment results of model machine indicate that the system has reliable performance which can satisfy the need of auto-solar track, it can also make the panel orient towards east again after darkness to realize daily circular run and it is of relatively high practical value.

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.

Solar energy has been one of the most explored sources of renewable due to its economical source of energy. However, the main barrier for solar energy generation is the present of dust particles on the panel surface that decreases its performance. Hence, persistent monitoring on dust accumulation is of importance to guarantee the optimum power is achieved. Thus, this research aims to develop the real-time dust monitoring system of the solar panel. A dust sensor with IoT will be developed for this purpose.

Solar energy has been considered as a promising renewable energy source for electric power generation. Solar panel systems have become a popular object to be developed by researchers, but the low efficiency of solar panels in energy conversion is one of the weaknesses of this system. Factors that affect the output produced by solar panels are the intensity of sunlight and the working temperature of the solar panels. The solar panel module has a single operating point where the voltage and current outputs produce the maximum power output. There are three main methods in Maximum Power Point Tracking (MPPT), namely conventional methods, artificial intelligence methods, and hybrid methods. In most solar panel systems, this study uses Maximum Power Point Tracking (MPPT) with perturb and observe algorithms to maximize the use of solar energy. The maximum power point extracted by MPPT will be supplied to the battery and controlled by the Charge Controller. The energy stored in the battery will be used by the Thermo Electric Cooler cooling system to reach the desired temperature point using the keypad as temperature input.

A solar panel is a device that can convert solar energy into electricity. The use of solar energy sources can be utilized as street lighting and garden lights. Today many use of solar panels mounted in static (silent) positions in one direction at one focal point will not get the maximum power point of the sun and sunlight received by the solar panel slightly so that it is inefficient at the time of charging the battery.The amount of solar energy that can be absorbed depends on the absorption of sunlight. Absorption can be optimized by making solar panels can continue to face the sun. This system uses ATMEGA8535 microcontroller with one temperature sensor to detect high solar thermal temperature received by solar panels and four photodiode sensors as a detection of light reflection received. These sensors can be able to provide a dynamic solar panels that are automatic and optimal in absorbing sunlight. With the absence of the use of solar panels as the lighting of the garden lights in Stmik Amik Riau and still using electrical energy from PLN, the purpose of this study is to build a solar panel control device that is able to follow the movement of the direction of the arrival of sunlight so it will be optimal in absorbing sunlight.Keywords: Solar Panel, microcontroller, Temperature Sensor, Photodiode Sensor

Solar energy is act clean as well as renewable source of energy. Hence the use of PV systems has used in many applications. Big-spread use has resulted in decreased solar panel production expenses. But the low effectiveness of a solar panel owing to variables such as solar insulation, clouds and shading impact continues one of the greatest issues. Due to variable concentrations of isolation, the panel output remains variable during cloudy weather. To increase the solar panel's efficiency, the maximum algorithm for power point tracking needed as it was discovered only a small percentage of the energy incident is transformed into electricity. DC-DC Converter (Boost Converter) design helps to increase the panel output, thereby improving effectiveness and output voltage using reasonable control technique. This article discusses the development of the fluctuating MPPT logic control to track the maximum output point and also to compensate for fluctuating power during cloudy weather. The suggested primary circuit block diagram. The simulation study is carried out and the proposed circuit is implemented by hardware. MATLAB Simulink is used for simulating the circuit.

Tracking maximum power point of a solar panel is of interest in most of photovoltaic applications. Solar panel modeling is also very interesting exclusively based on manufacturers data. Knowing that the manufacturers generally give the electrical specifications of their products at one operating condition, there are so many cases in which the specifications in other conditions are of interest. In this research, a comprehensive one-diode model for a solar panel with maximum obtainable accuracy is fully developed only based on datasheet values. The model parameters dependencies on environmental conditions are taken into consideration as much as possible. Comparison between real data and simulations results shows that the proposed model has maximum obtainable accuracy. Then a new fuzzy-based controller to track the maximum power point of the solar panel is also proposed which has better response from speed, accuracy and stability point of view respect to the previous common developed one.
