Objective:This research seeks to solve the problem of storing solar energy in small scale modules for domestic use.Method:The Solar Power Bank (SPB) was constructed with local materials based on their individual properties. The functionality of the SPB was tested in a convective environment. Davis automatic Weather Station (DWS) was used to get the weather parameters (like solar irradiance, solar energy and temperature) for each day the SPB was tested. The maximum solar irradiance for four days (during the experiment) were 220 W/m2, 208 W/m2, 450 W/m2and 900 W/m2. The maximum solar energy was 0.33 J, 03 J, 0.64 J and 1.33 J.Result:The maximum voltage and power obtained from the Solar Power Bank (SPB) was 0.18V and 0.065W respectively. The design showed tremendous heat energy entrapment during solar irradiance peak as the temperature in the SPB was about three times the DWS.Conclusion:It was specifically noted that the convection of the heat transfer that is triggered by the glass shield determines the functionality of the thermo-electric module. This is a clear indication that though the power output may be low to charge the batteries, the prospects of the SPB to operate in convective-rural communities (in tropic region) is very high.

Abstract—This paper presents the design of a 2kW portable photovoltaic (PV) stand-alone facility (PV generator) that converts directly solar irradiance into electricity for immediate use or storage. The project aims to build a stand-alone solar power source for use in rural villages, mountainous and remote areas that are distant from the national grid. It can also be very useful for powering camping tents, fishing boats, small farms, and greenhouses. Equally, it could be used for disaster stricken areas and during power outages. However, the proposed generator will be more suited for camping trips that Emiratis take almost in weekly basis. The paper will focus on presenting the main features of the designed prototype. It will also investigate the performance of the proposed stand-alone PV generator. Parameters investigated include geographic location, climate condition, solar irradiance, load consumption, ambient temperature, array voltage, battery voltage, and energy output from the array. The work presented is based entirely on the work carried out by final year electrical engineering students, during their capstone design project. The project work, presented, is a manifestation of the students learning during earlier semesters. It puts into practice the application of solar energy technology, that the student learned in his course on renewable energy systems.  Index Terms—Solar energy,transportable solar system,stand-alone system,PV,photovoltaic system.

Solar irradiance is the most vital aspect in estimating the solar energy collection at any location. Renewable energy setup at any location is dependent on it and other ambient weather parameters. However, it is hard to predict due to unstable nature and dependence on variations in weather conditions. The correlation of ambient weather factors on the performance of solar irradiance is analysed, by collecting the data using weather API, over the year for a particular location of central India. The training of this non-linear data is carried out with hybrid regression model integrating decision tree regression with Artificial Neural Network (ANN) module. Experimentation is performed using real data of different days from different seasons of the year, also by considering different irradiance conditions. The results demonstrated significant weather factors with moderate positive and negative correlation with solar irradiance, which can be used as a helpful tool to predict it before deployment of solar energy setup.

A small scale prototype of functional R&D solar tower system (about 10 kW) to gather solar energy and store it in a molten salt tank will be designed, developed and built. The prototype tower system will be built at King Abdulaziz University in Jeddah, Saudi Arabia where direct irradiation is very high. Collectors of large mirrors (called heliostats) will be used to track the incident sunrays. The heliostats focus the energy flow towards solar receivers, where energy is transferred to a working thermal fluid. The proposed system consists of several heliostats directing incident solar rays to a tower of height about 20 meters. A solar receiver will be installed at the top of the tower to collect solar energy reflected from the heliostats. The heat transfer fluid (HTF) re-circulated in the receiver transfers the collected heat in the receiver to a storage tank. The storage tank contains molten salts.

Nigeria is endowed with abundant energy resources, both conventional and renewable, which can potentially provide the country with a sufficient capacity to meet the ambitions of both urban and rural Nigerians of a full, nationwide electrification level. Yet, Nigeria has one of the lowest consumption rates of electricity per capita in Africa. With the demand superseding the generation, there is inequitable access of rural communities to the electricity service in the country. There are inherent obstacles militating against the effective implementation of an orderly energy policy in Nigeria. The inefficiencies over shadowing the allocation of energy resources coupled with the near depletion of fossil fuels, make it imperative for the country to exploit its huge natural renewable resources to avoid a worsening energy supply scenario and provide feasible solar water pump to rural dwellers. This paper presents the applications of solar water pumping which are already quite significant and are growing at steady rate. Solar energy is suitable for small-scale water pumping in remote areas where the demand is regular, such as for drinking water, but it may also be used for irrigation. Most areas in Nigeria have climates suitable for solar pumping. A review is given of the use of solar energy for water pumping to improve the living conditions of the population in rural areas and to develop techniques for utilization of solar energy in a tropical environment condition. Results, suggests that, solar powered water pumping must be encouraged, promoted, invested, implemented, and demonstrated by full scale in Nigeria.

Abstract Solar Energy is the most popular among several clean energies. As a tropical country, Indonesia has big opportunity to develop solar power, particularly in East Kalimantan which spans around the equator. Solar energy generation, however, is influenced by weather parameters which give uncertain values of the amount of the captured energy. Therefore, this research is conducted to overcome the effect of weather towards solar energy. The aim of this research is to examine the model for sun power forecasting based on the data. The Artificial Neural Network (ANN) and Multiple Linear Regression have taken as the approach models to determine energy forecasting. This study used five input variables; temperature, precipitation level, humidity, wind speed, and surface pressure, while the solar radiation was taken as the output variable. Moreover, the daily solar power and weather data from East Kalimantan has been taken along the period of 27th July 2018 – 28th July 2021. The result of this study showed that the RMSE of ANN was slightly similar with the multiple linear regression methods which were calculated by 160.26 and 160.46 respectively. However, the ANN is preferable to use in the solar energy forecasting since the tendency of nonlinearity of the climate data.

With the trend of falling costs associated with solar energy production, solar adoption is currently picking momentum in India at the state and federal level. Solar power is being adopted by universities, factories and other large entities readily, but is not prevalent for small scale consumption or for land owners of smaller plots in urban areas. These landowners represent a large chunk of development and their adoption can bring solar energy to the masses, galvanizing forces of agglomeration of economics. Surface area for installation of solar power is essential for solar adoption at any meaningful scale, especially for residential use. Installation of a solar array below the requirement leads to supplementation by the electrical grid and dealing with two different power sources and thus unpopular. The paper calculates this requirement for the average household and a minimum energy demand threshold is identified, below which solar adoption will not make sense to the urban household. Further, the area required for solar installation to meet this demand threshold is calculated. The paper finds this area requirement to be out of reach for most households, which has been identified as an impediment to solar adoption by urban households.

There is great potential for generating solar energy using unused space on roofs and vacant lots around buildings. Small amounts of energy generated by each individual household, industrial building, commercial building, or any other type of building can be used to partially meet the needs of the building's residents, and the surplus, if any, can be fed to the grid. To use the existing roof space of buildings, SPV systems on the roof of buildings can be installed to replace DG generators installed to provide the minimum load required to operate during load shedding. TSTU has a large unused roof area from both residential and office buildings. Therefore, it has a huge potential for generating solar energy by installing a grid-connected Solar system on the roof. We can reduce a large amount of bills by implementing a solar power plant. The government has also launched various solar energy incentive schemes, this article provides a brief overview of rooftop photovoltaic and small-scale solar generation systems, and discusses various government schemes. Since TSTU has a large scope for this scheme, so the calculation of the design capacity was made for the technological College and one residential building. A method has been developed for calculating the capacity of Autonomous solar power plants and its elements, which allows us to take into account changes in the load during the day and thereby accurately determine the required capacity of the battery and eliminate unjustified overestimation of the power of power plant elements and increase the cost of the Autonomous solar power plant itself.

The significance of sustainable power source has expanded because of environmental change and worldwide cautioning concerns because of its renewing quality. Solar energy is the focal point of numerous examinations due to modern industrial applications and small scale local applications in emerging nations. Solar energy is being bridled, either specifically utilizing photovoltaic or secondarily utilizing concentrated solar power. This study aims to design and fabricate a small scale concentrated solar power (CSP) plant using linear parabolic trough. Linear parabolic trough collector is used because of high efficiency and exceedingly prescribed kind of CSP. The scope of this study is to develop a CSP plant and also study the properties of various thermal fluids and expect the best transfer medium. The study done in this research is based on carrying out a detailed energy balance scheme for a linear parabolic trough collector while observing twenty-six vital design parameters, including the geometric measurements and material properties of concentrator and receiver pipe, thermal fluids properties, and operating conditions. Modeling of the system is carried out for different thermal fluids that are deemed viable for use. It was found that the results obtained from the fabricated parabolic trough CSP were used to verify the model and compare with the theoretical results. The conclusions deduced from this study will help design both small and large scale applications of linear parabolic troughs.

The study was conducted in Wai Sari sub-watershed, Western Seram Regency Maluku to develop an accurate land degradation assessment model for tropical small islands. The Stocking’s field land degradation measurement and RUSLE methods were applied to estimate soil loss by erosion and the results of both methods were statistically tested in order to obtain a correction factor. Field indicators and prediction data were measured on 95 slope units derived from the topographic map. The rates of soil loss were calculated according to both methods, and the results were used to classify the degree of land degradation. The results show that the degree of land degradation based on the field assessment ranges from none-slight (4.04 - 17.565 t/ha/yr) to very high (235.44 - 404.00 t/ha/yr), while the RUSLE method ranges from none-slight (0.04-4.59 t/ha/yr) to very high 203.90 - 518.13 t/ha/yr.  However, the RUSLE method shows much higher in average soil loss (133.4 t/ha/yr) than the field assessment (33.9 t/ha/yr). The best regression equation of  logD/RP = - 0.594 + 1.0 logK + 1.0 logLS + 1.0 logC or D = 0.2547xRxKxLSx CxP was found to be a more suitable land degradation assessment  model for a small-scale catchment area in the tropical small islands.
