DHVSU Electrical Engineering Department Goes Green: Feasibility of Solar-Powered Building Using an Off-Grid Hybrid Solar Inverter

This research project unfolds the practicability of utilizing an Off-Grid Hybrid Solar Inverter to power up the Electrical Engineering Building in Don Honorio Ventura State University. To satisfy the aims of this research, a Solar PV System design was used to make use of the solar energy converting it to electrical energy to supply the whole building. This study was guided by doing a load schedule of all the appliances in the whole building to acquire the total power and total energy consumption, using it as a basis for the selection of the required electrical components and computation of the roof area to select a suitable solar panel in order to ensure the functionality of the whole Solar PV System. The raw data gathered was analyzed using formulas to acquire the needed electrical values. The findings resulted in the development and completion of the Solar PV System Design. The last part of the research is the results, discussions, conclusions, and recommendations. These provided the finalization and endorsement of the whole study.

The occupational safety implications of the California residential rooftop solar photovoltaic systems mandate

Introduction: A 2018 change to the California building code mandates that new residential construction in the state include rooftop solar photovoltaic power systems beginning in 2020. As residential construction (especially work on rooftops) is among the more dangerous occupations in the United States, this paper seeks to quantify the increased risks to workers as a result of this mandate. Method: An analysis of the trends by occupation of nonfatal safety incident rates in the United States combined with a Monte Carlo simulation provide an estimate of the uncertain impact of this new mandate. Results: Recordable safety incidents are anticipated to increase by a total of 16.6 incidents (standard deviation = 1.0 incidents) over the 2020–2029 time period as a result of this policy change. However, lessons from Germany and other industries offer potential avenues to reduce the negative social impact of this mandate. Conclusions: While it is not possible to increase employment in any sector without increasing the expected number of occupational injuries to some degree, these results indicate that risks could be considerably reduced by making solar PV system design decisions that increase worker productivity and reduce roof exposure time. Practical Applications: Changes such as eliminating work on roofs could decrease the expected number of recordable injuries over the 10-year period by 0.30 incidents per year (a reduction of 18%).

Analysis and design of solar PV system using Pvsyst software

Nowadays, Afghanistan is facing a challenging energy situation; the electricity consumption to the national Grid is imported from neighboring countries, such as Iran, Uzbekistan, Tajikistan and Turkmenistan. This country is annually paying 280 million dollars to the neighboring countries for importing 670 MW. Nevertheless, the country is still facing a shortage of electricity in the rural area. To overcome these issues, the government of Afghanistan is planning to generate 5,000 MW of renewable energy by 2032; among them the share of solar projects should be 1,500 MW. According to the Afghanistan Renewable Energy Union (AREU), solar projects would cover 30% of electricity demand in 2032. The Daykundi province is located in the center of Afghanistan, which is having great sunlight to generate solar energy. The designing of 700KWp has been tested on Pvsyst software in which the system production is 1266MWh/yr. The performance ratio is 0.797. Therefore when the power factor is between (0.7–0.9) the system is working in good condition, solar energy technology is increasingly being recommended for electricity production. In this paper the simulation of a 700KWp Grid-connected solar power plant in Daikundi province of Afghanistan is presented with the use of Pvsyst software and all their performances have been evaluated.

Multi-objective design of grid-tied solar photovoltaics for commercial flat rooftops using particle swarm optimization algorithm

Flat roof solar PV design is an important and challenging process as it requires various parameters to be considered (such as weather, location, shading, regulations, purpose of use, etc.), and standard guidelines for building a solar PV system are not currently available. An even more challenging task is to improve the design of a solar PV system in order to optimize energy generation in a cost-effective manner, particularly in high-latitudes. In the present research, in order to determine optimal system size, parameters optimization should be carried out. The primary focus of this study is to develop an optimized system which maximizes generating capacity while maintaining cost-effectiveness of the solar PV system prior to the system implementation. Hence, a multi-objective optimization model is developed. The solar PV system design process is improved by optimizing the tilt angle and the inter-row spacing of solar PV modules. An objective function is developed based on the total solar energy generation per PV system and energy generation per PV module in order to improve cost effectiveness. The goal is to maximize these two outputs of the objective function. The particle swarm optimization (PSO) method is used to accomplish the optimization. Given that the two objectives are different and both have equal and opposite effects on the other, modifications are made to the PSO. Finally, the outputs of the optimization model are compared and validated with a case study. The model presented in this paper will assist users in decision making based on the technical output and financial aspects of the PV system.

Direct Use of Solar PV System Generation with Minimum Batteries Capacity

The aim of this work is to present of a specialist design of solar PV system to provide load at (8a.m. to 2p.m.) as daily energy consumption, by expanding in solar panels numbers with reducing battery numbers, consider the cost of batteries proportionally to solar panels cost. The specialist design depended on load consumption (6) hours between (8 a.m. – 2 p.m.) at sunshine day to supply power to load directly from the PV system generation with little contribution battery energy. The results show specialist design can be useful for this situation of covering load consumption in (6 hours) band benefit to used PV system to reduce the solar PV systems cost, was the performance analysis of this system from April to October.

Design and cost analysis of 1 kW photovoltaic system based on actual performance in Indian scenario

Summary The exhaustion of conventional resources and its effect on climate requires an urgent call for the substitute power resources to convene up the current power requirement. Solar energy is an endless, unsoiled and prospective energy source among all other nonconventional energy options. As more concentration is being done on focal point for the development of renewable energy capital globally. To ascertain their viability it is necessary to do the economic and technical assessments of these resources. This paper presents designing aspects and assessments of solar PV system based on field and actual performance. The study is based on design of solar PV system and a case study based on cost analysis of 1.0 kW off-grid photovoltaic energy system installed at Jamia Millia Islamia, New Delhi (28.5616° N, 77.2802° E, and about 293 m above sea level) India. Both monthly and weekly costs of energy produced by the 1 kW PV system have been calculated. In addition, the solar PV 1 kW system can give internal rate of return of about 1.714% on investment. Based on assumptions used in this study, solar 1 kW PV system of Rs. 0.9724/kWh is estimated for a project with profitable life of 25 years with no other financial support. This translates to Rs. 80,000 payment over the livelier cost of energy of 1 kWh generated by the system. However, if the financial support is more than 50% of the initial investment cost, no further payment fee is necessary to support this type of system. Basically this system has been designed for small home located at the place of availability of grid power is rare. 1 kW PV solar system is also very useful in rural areas of India. India as a subcontinent receives great amounts of solar radiation annually.
