“…Our review of literary sources [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24] shows that their authors took the angular position of the Sun at noon relative to the plane of the Earth's equator as the angle of inclination of the Sun relative to the Earth, as recommended in [9]. It should be noted that this explanation of the angle of inclination suggests that the Sun changes its position by rotating around the Earth.…”

“…The above-mentioned studies are supplemented by the results of experiments reported in [23,24]. It was experimentally established that the use of a two-axis solar tracker increases the average annual production of electricity by 41 % [23]. In turn, the use of a uniaxial solar tracker increases the efficiency of the system by 57.4 % compared to a fixed solar panel installed at the optimal tilt angle [24].…”

The object of this study is photovoltaic modules in various installation options. The physical model of the Earth's illumination by a parallel flow of solar rays has been refined. The dependence of the cosine of the angle of incidence of the Sun's rays on the angular length of the day, as well as the average annual efficiency of the installation of photovoltaic modules, both fixed and with various tracking options, was determined. Refinement of the physical model implies determining the angle of inclination as the angle between the inclined axis of the Earth and its projection on a vertical plane, perpendicular to the line connecting the centers of the Earth and the Sun. This line passes through the center of the Earth. The concept of the average annual efficiency of the installation of photovoltaic modules is introduced as the annual weighted average value of the cosine of the angle of incidence of solar rays on the plane of the photovoltaic module. Various options for installing photovoltaic modules were analyzed: fixed horizontal on the equator; stationary, installed at an angle to the horizon; one that performs tracking in horizontal (vertical) planes; with full tracking. The efficiency of installing a photovoltaic module at each latitude can be equal to the efficiency of installing this module at the equator, that is, 47.93 % when installing the module at an angle of inclination to the horizon equal to the latitude. Tracking in the vertical plane makes it possible to increase the efficiency of the photovoltaic module installation by up to 50 %. Compared to full tracking, tracking in the horizontal plane at an angle of latitude makes it possible to obtain the efficiency of the installation of the photovoltaic module at the level of 97.93 %. The results could be used as a basis for evaluating the efficiency of the installation of photovoltaic modules at different latitudes with different techniques of their installation, as well as for the subsequent generation of electricity

“…The carbon emissions produced by solar panels only come from their manufacturing and recycling process. However, the emission value produced in the solar panel process is much smaller than the total emissions from the use of fossil energy for electricity generation [12] and also using the solar panels can reduce the CO2 emissions in amount of 651 ton for 25 years [13]. The use of solar panels at SMAN 96 is on school's rooftop as shown in Figure 4.…”

State Senior High School (SMAN) 96 is the first high school in Jakarta to be officially designated as a net-zero school with a Greenship Certificate by the Green Building Council Indonesia. In contrast, State Vocational High School (SMKN) 73 is not a net-zero school. The two schools are 100 m apart, located in Cengkareng District, West Jakarta. The purpose of this study is to analyze the application of CO2 emission reduction technology in the two schools. This study used a quantitative method. Because the school setting is in the urban area, it is not easy to find so-called indigenous technology. This study will look at the best available low carbon technologies implemented in both schools. The results show that SMAN 96 has electricity consumption and CO2 emissions lower than SMKN 73 because SMAN 96 already using the energy-efficient devices/appliances and minimizing the usage of AC and refrigerator which can increase the CO2 emissions. To reducing CO2 emissions, the two schools already implementing the use of solar panels. Furthermore, by using the solar panels it can save the electricity consumption and also solar panels produces emissions smaller than total electricity usage.

Using full factorial experiment to simulate electricity generation by solar batteries

The amount of electrical energy generated by solar batteries (SB) depends significantly on their position relative to the Sun. The presence of dependencies of the initial parameter of the SB on the factors determining this position allows finding the optimal orientation of fixed or partially fixed SBs. This paper presents the results of the study on the conditions of using a full factorial experiment for creating mathematical models — regression equations — to simulate the operation of solar batteries under the condition of reducing the amount of field tests necessary for this. It is shown that the simulation accuracy significantly depends on the range of factor values. The conducted study demonstrates that the use of a full factorial experiment in the range of factor values approaching all possible is appropriate for preliminary simulation of the solar battery operation and an approximate assessment of the simulation results in connection with significant errors. Narrowing the range of factor values significantly reduces the deviations of simulation results from experimental data, which in many cases can be accepted, especially if the simulation results are used for specific operating conditions of the solar cell. In order to create mathematical models that would more accurately approach the actual ones obtained experimentally, it is necessary to use dependencies for concretized values of factors.
