Abstract Photovoltaic panel as a producer of renewable energy is increasingly being utilized. The electrical energy produced by photovoltaic panel can be used for aeration in fish ponds located quite isolated and far from the main electricity grid. Aeration is important for fishery because it affects the dissolved oxygen level in the water. The system uses two units of 50 Wp floating solar panels and four units of DC aerator of 12 Volt/0.28 A. The measurement of solar irradiance, solar panel temperature, output voltage and current was conducted to monitor floating solar panel performance. Dissolved oxygen level measured in the water without aeration was 3 - 3.9 mg/L while after using floating photovoltaic panels to supply the electrical energy for aerators, dissolved oxygen level in the water was increased to 4.1 - 4.8 mg/L.

Solar panels are used to convert the energy from sunlight to electrical energy. The different impacts on the solar panel which influences the productivity of the solar panel are Sun movement and dirt which generate the fundamental impact on solar panel. Because of those impacts, less yield generated by solar panel so to increase the effectiveness of the solar panel is by utilizing tracking and cleaning technique. There is a framework which is mix of tracking and cleaning. In this cutting-edge world, power is likewise added to the most fundamental requirements in everybody's day to day existence. With the expanding request of power, destruction of the natural resources is done and will be used for energy generation. To adjust the shortage of natural resources unconventional fuels are used for power generation and are used by the most part of world. Among all the unconventional fuel sources, power created by solar panel energy is broadly utilized. The abundancy of this type of energy is more all around the earth. A framework which tracks sun as well as automatic washing of solar panel with automated instructions is required. The instrument requires a LDR for following the sun and for cleaning wiper module is required. Regarding every day energy production, the sun tracking - cum cleaning plan gives more energy output when contrasted with the fixed PV module. Without this framework this cleaning work is done by man force which is good for small scale but for large scale like power plant it is very difficult. Then led display is required to display the result of the framework.

Influence Of Temperature

All photovoltaic panel heats up when exposed to sunlight and this heating reduces the electrical power output of the same. This work presents the use of this unwanted waste heat, converting it into thermal energy directly by means of the Seebeck effect, which is the direct conversion of thermal energy into electrical energy by means of an arrangement of semiconductor materials that when exposed to temperature gradients generate electric current. In this work emphasis was placed on the influence of temperature on generation processes involved. Thus, the theoretical evaluation, it presents the mathematical models of thermoelectric and photovoltaic systems by raising the curves of voltage, current and electric power generated, and analyses the influence of temperature in each model. To obtain the simulation curves it uses MATLAB ® 5.3, taking into account the parameters of thermoelectric modules and real photovoltaic cells. In practical evaluation, a prototype was assembled containing thermoelectric module attached to the bottom of a photovoltaic panel in order to use the heat energy absorbed by the panel. The data were stored and analyzed, where we observed the influence of temperature in both systems, validating the mathematical modeling. It is the applicability of the mathematical model given the results obtained with the prototype system.

Solar charge controllers are currently a necessary piece of equipment when utilizing the energy from a photovoltaic system for charging purposes. However, a standard solar charge controller available today includes some drawbacks that may be crucial for specific applications. An alternate method of regulating energy from a photovoltaic panel can be accomplished by utilizing polymer-dispersed liquid crystal (PDLC) technology. Combining a solar panel with a proper PDLC material allows the input into the photovoltaic panel to be controlled. This method of power regulation can lead to increased efficiency, reduced cost, reduced weight, and increased safety when compared to a standard solar charge controller.

In the Modern Era, a source of electrical energy is very necessary, given the large number of electronic equipment that really requires a source of electrical energy. Solarcell is a device or component that can convert light energy into electrical energy. However, the energy used in this solar panel needs to be considered the efficiency of its use. Therefore it is necessary to monitor currents and voltages and loads in real time to determine the energy needs of solar panels for lamps. Monitoring of voltage, load and current on this solar panel is based on a microcontroller. The voltage generated by the solar panel and the battery voltage is measured using a sensor. It takes a Web and a modem device to send solar panel measurement data from a distance, with remote monitoring makes it easier to find out what the voltage and load is without having to be in place of the solar panel. Web as a control for lights, blackouts, dim and bright lights, on the web can monitor voltage and current values. The results of the microcontroller ADC are able to send data to the web. The data stored in the ms.excel file contains the voltage from the solar cell, the current at the load and the time when storing and charging the battery. The lights can only last 5 hours when all loads are active (ON), while charging (charging) for 13 hours when the battery is empty.
