- The rooftop of the University of Muhammadiyah Surabaya Integrated Laboratory building which has an area of 210 m2 can be used as a solar power plant (PLTS). Installing PLTS in buildings has several advantages, namely as a long-term energy investment and easy to integrate with the grid electrical system. PLTS is designed to save electricity consumption. In addition, if PLTS is connected to a battery, it can meet some of the energy needs at night. To design a PLTS installation in the Integrated Laboratory building, this research uses technical and economic analysis methods. Technical analysis is carried out to determine the capacity and number of PV mini-grid components required for installation. While the economic analysis aims to calculate the investment costs and the length of time for the return on investment compared to buildings without PV mini-grid installations. Based on this research, the results show that the amount of energy required for the Integrated Laboratory building is 482.148 kWh, while the planned PLTS is able to provide energy of 216,128 kWh. The PLTS design requires an initial investment of Rp. 927,700,894,-. So by using the Payback Period (PP) method, it can be concluded that the planned design is feasible, because the comparison of the cost of return on investment is 9.13 years faster than the project age that has been determined previously, which is 20 years.

“…Accordingly, there are various attempts to improve the efficiency of PV inverters in different aspects such as inverter topologies, power device technology and pulse width modulation methods [6]- [11]. Furthermore, the reliability of PV inverters has been analyzed by considering the impact of various factors such as mission profile [12]- [16], inverter topology [12], [13], DC-to-AC ratio [14], [15], and panel degradation rate [16]. However, there is a still lack of study on more comprehensive analysis on both efficiency and reliability together including the impacts of various factors.…”

It is required to reduce the cost of PV energy to be competitive as an alternative energy source. The efficiency and reliability of PV inverters are important aspects to be enhanced to reduce the cost of PV energy since they contribute to the reduction of operational and maintenance costs and to the increase of annual energy production. Therefore, more comprehensive analysis on both efficiency and reliability together including the impacts of various factors is required. In this paper, single-phase five-level NPC inverter topologies for photovoltaic systems are comparatively evaluated in terms of efficiency and reliability by simulations and experiments, in which the impacts of pulse width modulation (PWM) methods and installation locations are considered. The results are expected to give an insight to determine the proper topology and PWM method depending on its installation location considering the reliability as well as the efficiency and total harmonic distortion (THD).

“…In order to reduce carbon emissions in the world by the end of the century, growth must accelerate in the next decades, eventually leading to several connected Terawatts of PV capacity. 2019 records the third year with around 100 GWp of recent set up PV size, leading the additive installed capacity close to Terawatt globally by end of this decade [75] and installation location also affect lifetime of PV inverter [80]. For this geographically location of country play an important role for maximum power generation.…”

Optimum Photovoltaic (PV) system integration in power grid depend upon the total of power accessible from the PV. To figure the PV systems highest power yield, PV panels must be positioned at an optimal tilt angle (OPTA) to absorb maximum solar radiation (SR). This OPTA is a function of the latitude, clearness index, diffuse SR, global SR, direct SR and optimum PV size. Therefore OPTA has an impact on maximum power generation and optimal PV system sizing. The PV is not installed at OPTA for most of the sites in India which is important for maximum power generation and optimum sizing of standalone PV systems. This results in variation of OPTA from site to site and its effect on PV sizing needs to be investigated. The innovative aspect of this work is the calculation of OPTA, which are employed as sensitive factors in Hybrid Optimization of Multiple Energy Resources (HOMER), to determine their impact on maximum optimum sizing and power generation for 26 cities in India's various climate zones. This methodology can be applied all over the world to determine the impact of OPTA on maximum power generation and size. It is found that OPTA varies from 63⁰ to 0⁰ throughout year in India and it is maximum for December in India. The results indicates that Net Present Cost varies from $1105 to $1280 and Cost of Energy (COE) variation is 0.041 to 0.048 $/kWh throughout India cities and low temperature sites are good for photovoltaic (PV) power generation. Two axis tracking system produces more power in comparison to other tracking systems. This research is beneficial for researcher and industry to install PV system in different climatic zones of India to generate maximum power at minimum cost of energy.
