Seasonal Weather

Solar energy usage is thriving day by day. These solar panels are installed to absorb solar energy and produce electrical energy. As a result, the efficiency of solar panels depends on different environmental factors, namely, air temperature, dust (aerosols and accumulated dust), and solar incidence, and photovoltaic panel angles. The effects of real conditions factors on power and efficiency of photovoltaic panels are studied in this paper through testing the panel in real environmental tests. To study the mentioned parameters precisely, two panels with different angles are used. The case study is regarding a region of Tehran, Iran, in summer and winter seasons. The results show that panel efficiency during winter is higher than summer due to air temperature decrement. It is discovered that among air pollutants, Al and Fe have the most share in polluting the air that affect the photovoltaic efficiency. Moreover, measuring the accumulated dust on the panels shows more amount in winter in comparison with summer. The important point in studying the effect of tilt angle is that inconformity between solar incidence and photovoltaic panel angles would result in solar radiation absorption and eventually panel efficiency loss and also, photovoltaic panel installation angle would affect the amount of dust deposited on its surface.

Indonesia has more than 17,000 islands and has plenty of beautiful beaches and underwater spots which have great potential for maritime tourism. Tourism was ranked 3rd on Indonesia's foreign income and plays an important role for the country’s ecomony. Despite having potential advantages, the government has not yet maximized its efforts to develop the attractiveness of its maritime tourism. Beside the beautiful spots Indonesia is also blessed with all year long sun shine, which could be tapped as renewable and green energy as substitution to fossil fuel. Refer to these great advantages of natural resources the research was aimed to support the government’s program in developing its maritime tourism and to promote the use of green and renewable energy by designing a solar-powered tourism recreational boat which has 12 meters of length. The paper is focused on the design of solar energy and its electrical system, which includes conversion of solar energy to electrical energy and store it in the battery, the required electrical power is also predicted based on the appliances and equipment installed in the boat, the optimum attachment of solar panels on the boat structure is also calculated. All the methods and information we use are obtained from literature study, discussion with experts, and surveys to Jagur as solar-powered electric boat from Universitas Indonesia.

The sun is a source of energy that cannot be used up. Therefore, the utilization of solar energy must be a priority. With the many types of solar panels that have been developed, researchers conducted an analysis of 150 watt monocrystalline solar panels. The purpose of this study is to know the amount of current and voltage produced by solar panels in some conditions of the sky, namely cloudy, bright cloudy, and bright. The research method used was the experiment. From the data that has been obtained, it can be found that the energy produced by solar panels during cloudy ranges from 0.6-0.8 amperes, when it is cloudy, 0.9-1.9 amperes, and when bright 2.0-3.2 amperes. The amount of electrical energy that can be produced is 8%. However, if the sunny state can produce twice that Suggestions for readers are if you want to take data to make sure the solar panels are completely exposed to the sun during data collection and in the open area. Much better if the angle is adjusted in the direction of sunlight.

Solar energy is considered the greatest source of renewable energy. In this paper, a case study was performed for a single-axis solar tracking model to analyze the performance of the solar panels in an office building under varying ambient temperatures and solar radiation over the course of one year (2018). This case study was performed in an office building at the College of Engineering at Shaqra University, Dawadmi, Saudi Arabia. The office building was supplied with electricity for a full year by the designed solar energy system. The study was conducted across the four seasons of the studied year to analyze the performance of a group of solar panels with the total capacity of a 4 kW DC system. The solar radiation, temperature, output DC power, and consumed AC power of the system were measured using wireless sensor networks (for temperature and irradiance measurement) and a signal acquisition system for each hour throughout the whole day. A single-axis solar tracker was designed for each panel (16 solar panels were used) using two light-dependent resistors (LDR) as detecting light sensors, one servo motor, an Arduino Uno, and a 250 W solar panel installed with an array tilt angle of 21°. Finally, an artificial neural network (ANN) was utilized to estimate energy consumption, according to the dataset of AC load power consumption for each month and the measurement values of the temperature and irradiance. The relative error between the measured and estimated energy was calculated in order to assess the accuracy of the proposed ANN model and update the weights of the training network. The maximum absolute relative error of the proposed system did not exceed 2 × 10−4. After assessment of the proposed model, the ANN results showed that the average energy in the region of the case study from a 4 kW DC solar system for one year, considering environmental impact, was around 8431 kWh/year.

The Cost

It is becoming increasingly important to include information about power generation from renewable energy sources in the training of electrical engineers. Solar energy is arguably the most common renewable energy source in use today. Providing practical hands-on training on solar energy power generation today requires the use of photovoltaic panel devices which are used for transforming solar energy into electrical energy. In many developing countries, practical hands-on training on solar power generation is limited due to the cost of photovoltaic panel devices and so the training consists of theoretical and tutorial classes sometimes supported by remote and virtual laboratories. This paper presents an augmented virtuality tool where real-time information from a mobile device’s sensors is used directly within a virtual or computer generated environment. The tool provides a practical context for hands-on tutorial exercises on solar energy power generation.

The transfer of electrical energy sources from non-renewable fossil fuels to alternative renewable fuels can be made by utilizing solar energy. The working system of arduino uno solar tracking system for STMIK AUB garden lights is by capturing solar energy through solar panels which are then stored inside the battery where the charging process is controlled by solar charge controller. LDR functions to receive and identify the radiated light quantities which are then forwarded into the arduino uno and processed to drive the DC motor that has become one with the solar panel. If the day begins to darken the LDR will inform the arduino uno and then it will be processed by arduino uno to turn on the DC light.

Alternative Source

The need of electricity in every ship are very diverse. Power plants for using diesel as an engine can also come from sunlight as an alternative source of electrical energy. The measurement of solar energy in Indonesia is 4.8 kWh /m2. This renewable energy is in suitable for the Indonesian topography. Thus, the energy from the sunlight around the equator is so abundant that its availability is always available throughout the year, except when it rains. Utilization of solar energy can be used as a substitute for conventional energy which is starting to be limited and the price is quite expensive. Therefore, the data that are presented in this paper comes from publications, manufacturers, relevant official government documents, scientific publications and other publications. Utilization of solar energy as electrical energy can be done by using solar panels mounted in ships. The generated electricity can be used to turn on electrical equipment and send lights at night, and can be used as fishing aids. The use of solar power plant can also have a positive impact on fishermen, such as improving health, economy, environmental sustainability, and building independent fishermen.
