# numericals on solar energy

(v) For a compact and thin panel design, the losses of the absorbed solar energy to the surrounding were mainly through the front and back panel surfaces, and the edge loss was negligible. j A numerical model of the Solar System is a set of mathematical equations, which, when solved, give the approximate positions of the planets as a function of time. The results of this simulation can be compared with past measurements to check for accuracy and then be used to predict future positions. + − Then, using these new values one starts over the whole calculation for the next time-step Δt. → A completely different method is the use of Taylor series. t 0 j To allow for an excessively rapid change of the acceleration when a particular body is close to the reference body, it is customary to introduce a small parameter e so that = + i • Auxiliary energy sources - is diesel generator or other renewable energy sources. Evidently tricks are to be applied to reduce the amount of work. The photons comprising the solar radiation can be converted directly to electricity in photovoltaic devices, or, in concentrating solar power (CSP). As such only the latter was used in former times. G Conventional silicon heterojunction solar cells employ defects‐prone a‐Si:H layers for junction formation and passivation purposes. There is no known exception to this law—it is exact so far as we know. i 1. Numerical Simulation of Solar Cells and Solar Cell Characterization Methods: the Open-Source on Demand Program AFORS-HET, Solar Energy, Radu D Rugescu, IntechOpen, DOI: 10.5772/8073. The simulations can be done in either Cartesian or in spherical coordinates. M t Combining the bodies in groups as in the previous and apply larger and thus less timesteps on the faraway bodies than on the closer ones, is also possible. Substituting these layers with hole‐selective MoO x and electron‐selective TiO x can reduce parasitic absorption and energy band offsets issues associated with doped silicon films. r i ′ 3 • Load – is electrical appliances that connected to solar PV system such as lights, radio, TV, computer, refrigerator, etc. + In essence this mathematical simulation of the Solar System is a form of the N-body problem. j A commonly used solar collector is the flat-plate. r G Available from: Rolf Stangl, Caspar Leendertz and Jan Haschke (February 1st 2010). Several methods are available. ≠ − + i , and: = <> r Energy output is a function of power (installed capacity) multiplied by the time of generation. Rather than to work in SI units, which would make some values extremely small and some extremely large, all units are to be scaled such that they are in the neighbourhood of 1. Based on the energy balance analysis of each layer, mathematic models were developed for the numerical simulations on energy performance study. j v ′ r The Society was founded in 1954 and is now incorporated as a non-profit educational and scientific institution. The simplest way to solve these is just the Euler algorithm, which in essence is the linear addition described above. d {\displaystyle {\vec {a}}_{j}=\sum _{i\neq j}^{n}G{\frac {M_{i}}{|{\vec {r}}_{i}-{\vec {r}}_{j}|^{3}}}({\vec {r}}_{i}-{\vec {r}}_{j})}. The symbol N represents the number of bodies, which can grow quite large if one includes the Sun, 8 planets, dozens of moons, and countless planetoids, comets and so forth. As perhaps the most promising of all the renewable energy sources available today, solar energy is becoming increasingly important in the drive to achieve energy independence and climate balance. The modern method consists of numerical integration in 3-dimensional space. Attempts to create such a model established the more general field of celestial mechanics.The results of this simulation can be compared with past measurements to check for accuracy and then be used to predict future positions. form of heat energy in it. 2 Strictly speaking, the latter was not much less calculation intensive, but it was possible to start with some simple approximations and then to add perturbations, as much as needed to reach the wanted accuracy. 5O�Y�_z��F�u�5��Eb�����7z�����8�J�uK9�����)��r�����"`�A���k�WS-�-�H[v�b�yFA������n�6���(j$��P-� K�>���x�ZW�俀��{��~L��z��I�W���i�]�˯W�������sJ��L�G��x�����_.���Es�;��(��X���X�a��(�~���g�W� i���Eմ�i�'p� N]���᠉�'X�A�ƞt�\��)��%����]�2��DO�k�e����`�-a���5�~_����Y��߆&�p��:�v��hn�J�]��=ؕ�ky$�)=bknC��]{|�a�������a'�ɩ1gYhϦ�� 1�Z�-�%��� ����+�Gd����U�|�lr�͘Ʌ���{�;�{����X&]f�. M j i Effect of insulating of solar collector on the heat loss was studiedand the numerical results showed that the insulation can reduce the overallheat loss significantly. Planets can no longer be considered as particles, but their shape and density must also be considered. Numerical investigations on the convective heat transfer in open cavities have been reported in literature (Le Quere et al., 1981, Penot, 1982, Chan and Tien, 1985, Skok et al., 1991). {\displaystyle \Delta v_{x}=a_{x}\Delta t} If the highest possible accuracy is needed, the calculations become much more complex. 3 Faculty of Nuclear Engineering, University of Shahid Beheshti, Tehran, Iran Some corrections might be still several degrees large, while measurements can be made to an accuracy of better than 1″. x M Δ This is what happens when using the Runge-Kutta method, especially the one of grade 4 or 5 are most useful. 2008 and 2035 will be primarily derived from wind and hydro power, which will contribute 36% and 31% of the additional demand respectively. ( − n x ∑ • Battery – stores energy for supplying to electrical appliances when there is a demand. Due to stochastic nature of solar energy the use of heat storage technologies are necessary to realize its full potential. This procedure is repeated for all other bodies. Because while at any time the position is changed by the acceleration, the value of the acceleration is determined by the instantaneous position. Cheap fossil fuels have had an enormous part in making renewable energy seem expensive. r A numerical model of the Solar System is a set of mathematical equations, which, when solved, give the approximate positions of the planets as a function of time. By far the most important trick is the use of a proper integration method, as already outlined above. List of solar energy projects that are being built by TANGEDCO Last Modified: Thu Mar 05 2020 21:20:14 GMT+0530 (India Standard Time) 2,000 MW The former equation (gravitation) may look foreboding, but its calculation is no problem. Its main use therefore is in preparation of almanacs. The solar constant (G SC) is a flux density measuring mean solar electromagnetic radiation (solar irradiance) per unit area. Once this is solved the influences moons and planets have on each other are added as small corrections. Corrigendum to “Spectral technique for accurate efficiency measurements of emerging solar cells”. Δ 0 <>>> a There is a fact, or if you wish, a law, governing all natural phenomena that are known to date. These are small compared to a full planetary orbit. but rather than developing up to some higher derivative in r only, one can develop in r and v (that is r') by writing However the influence of the Sun on any other body is so large, and the influence of all the other bodies on each other so small, that the problem can be reduced to the analytically solvable 2-body problem. Limiting ourselves to 1 dimension only in some general computer language: As in essence the acceleration used for the whole duration of the timestep, is the one as it was in the beginning of the timestep, this simple method has no high accuracy. In the case of comets, nongravitational forces, such as radiation pressure and gas drag, must be taken into account. During the nights, due to non-existence of solar energy, no contribution is made to the pond’s thermal energy [11]. By calculating these amounts after every time step the simulation can be programmed to increase the stepsize Δt if they do not change significantly, and to reduce it if they start to do so. x = Energy 206 (2020) 770–777] . All bodies in a particular direction and on large distance from the reference body, which is being calculated at that moment, are taken together and their gravitational attraction is averaged over the whole group. We will begin with a quote from The Feynman Lectures on Physics. Solar … %���� 1 0 obj t + To calculate the accelerations the gravitational attraction of each body on each other body is to be taken into account. If one wants to know the position of one planet on one particular time, then all other planets and all intermediate time-steps are to be calculated too. → <> 2 Faculty of New Sciences & Technologies, University of Tehran, Tehran, Iran. Evidently a full integration is needed. j − ) + x → Cheap energy has helped bad building designs to get built because we don’t need to insulate or think about solar aspect anymore. %PDF-1.5 Although this method is no longer used for simulations, it is still useful to find an approximate ephemeris as one can take the relatively simple main solution, perhaps add a few of the largest perturbations, and arrive without too much effort at the wanted planetary position. To increase the accuracy of the simulation not only more decimals are to be taken but also smaller timesteps, again quickly increasing the amount of work. Then also the total energy is no longer a constant (because the four vector energy with linear momentum is). j = − i Hence, the daily quantity of thermal energy obtained using collectors will be: Thermal energy = 6.5 [kWhÊ(solar)] m2Êday [0.20ÊkWhÊ(thermal)] [1ÊkWhÊ(solar)] = 1.3 kWh m2Êday This means that for every square meter of collector surface area, 1.3 kWh of heat are produced every day. H 2 /CO production via H 2 O/CO 2 splitting powered by concentrated solar energy is a promising pathway for energy conversion/storage. Solar Energy . Much better results are achieved by taking a mean acceleration, the average between the beginning value and the expected (unperturbed) end value: Of course still better results can be expected by taking intermediate values. ( | The latter equations (motion laws) seems simpler, but yet it cannot be calculated. y Energy generation is therefore a function of how much solar capacity is installed. 0 2 x r Ta�[>�V���g�/���4�d��v[rc/�RF�k�%Z��k^�>�쩩µ\3w��~���a'��yJ�SD�Z;�. = = Semiconductors have the capacity to absorb light and to deliver a portion of the energy of the absorbed photons to carriers of electrical current – electrons and holes. = z Solar Energy, the official journal of the International Solar Energy Society®, is devoted exclusively to the science and technology of solar energy applications.. d i 2 Long term models, going beyond a few tens of millions of years, are not possible due to the lack of stability of the Solar System. {\displaystyle a={\frac {GM}{r^{2}+e}}}. The effect of cavity geometry, inclination, receiver temperature through the aperture of solar cavity receiver has been numerically investigated using CFD package FLUENT 13.0. + This new book is the masterwork from world-renowned expert Dr. Soteris Kalogirou, who has championed solar energy for decades. Solar power generating capacity grew by 73.3% in 2011. [Sol. The result for each planet is an orbit, a simple description of its position as function of time. The disadvantage is that perturbation theory is very advanced mathematics. Δ For example, for distances in the Solar System the astronomical unit is most straightforward. Next one chooses a small time-step Δt and applies Newton's Second Law of Motion. Op- → {\displaystyle a_{x}={\frac {dv_{x}}{dt}}} x , x Numerical studies of cavity receiver convective losses are very limited. In the case of Mercury, and other planets for long term calculations, relativistic effects cannot be ignored. M. Ghalamchi 1,, M. Ghalamchi 2, T. Ahanj 3. The average solar radiation in winter is about 6.5 kWh/m2/day. g {\displaystyle (a_{j})_{x}=\sum _{i\neq j}^{n}G{\frac {M_{i}}{((x_{i}-x_{j})^{2}+(y_{i}-y_{j})^{2}+(z_{i}-z_{j})^{2})^{3/2}}}(x_{i}-x_{j})}, a x j The solar constant includes all types of solar radiation and not just the visible light. 4 0 obj a The book includes all areas of solar energy engineering, from … First notice the needed equations: a ) The most common method used is the leapfrog method due to its good long term energy conservation. a 0 The revision of this text hallmark text on Solar Energy has been done keeping in mind the current scenario in Solar Energy requirements. t endobj r | 2 0 obj Numerical Simulation for Achieving Optimum Dimensions of a Solar Chimney Power Plant. Attempts to create such a model established the more general field of celestial mechanics. It is a vector equation, so it is to be split in 3 equations for each of the X, Y, Z components, yielding: ( v For example, the flattening of the Earth causes precession, which causes the axial tilt to change, which affects the long-term movements of all planets. When also the mass of each body is known, the acceleration (ax, ay, az) can be calculated from Newton's Law of Gravitation. ) The velocity multiplied with Δt gives a correction to the position. x 1 Department of Energy Engineering, Science and Research Campus, Islamic Azad University, Tehran, Iran. 2 CiteScore values are based on citation counts in a range of four years (e.g. {\displaystyle \Delta x=v_{x}\Delta t}. In that case we write: This interactive chart shows installed solar capacity across the world. {\displaystyle r=fr_{0}+gr'_{0}} In reality this is not the case, except when one takes Δt so small that the number of steps to be taken would be prohibitively high. → Oxygen permeable membrane reactor serves as an alternative reactor concept for realizing this chemical path with the advantages of continuous production, easy integration, and high product selectivity. . ) The finite speed of light also makes it important to allow for light-time effects, both classical and relativistic. t The total amount of energy and angular momentum of a closed system are conserved quantities. stream The choice of units is important. = 3 {\displaystyle v_{x}={\frac {dx}{dt}}}. The results of a numerical study of the problem of natural convection in cavity receivers of solar parabolic dish collector have been presented in this thesis. x {\displaystyle r=r_{0}+r'_{0}t+r''_{0}{\frac {t^{2}}{2!}}+...}. = Heat storage can be accomplished through physical or chemical processes. j r ( CiteScore: 8.1 ℹ CiteScore: 2019: 8.1 CiteScore measures the average citations received per peer-reviewed document published in this title. z The disadvantage is that one must start with highly accurate figures in the first place, or the results will drift away from the reality in time; that one gets x, y, z positions which are often first to be transformed into more practical ecliptical or equatorial coordinates before they can be used; and that it is an all or nothing approach. n ( f The total solar energy potential in Turkey is 380×10 12 kWh/year, which ranks in top five among EU members 3.

Solar energy is greatly recommended as a source of renewable energy in wide range of in-house applications to large power plants. v Solar energy is becoming an alternative for the limited fossil fuel resources. Each body attracts each other body, the total acceleration being the sum of all these attractions. d Energy As this book is on Solar Energy, it is good to start the discussion with some general thoughts on Energy. The result is a new value for position and velocity for all bodies. e We just put the air-con on, and that will heat and cool the house at the touch of a button! The former are easier, but extremely calculation intensive, and only practical on an electronic computer. Capacity has grown in almost ten-fold over the past 5 years as shown in Fig. − The acceleration multiplied with Δt gives a correction to the velocity. As a result the book is updated with the energy scenario and the various applications of solar energy being used today. r Repeating this procedure often enough, and one ends up with a description of the positions of all bodies over time. r ) Numerical modeling was used forcalculation of conduction and convection heat losses from the receiver of thecollector. If this is not done one is almost certain to see a simulation abandoned in the middle of a calculation on a floating point overflow or underflow, and if not that bad, still accuracy is likely to get lost due to truncation errors. y Araujo GL and Marti A (1994), Absolute limiting efficiencies for photovoltaic energy conversion, Solar Energy Materials and Solar Cells 33: 213-240. Some of these tricks are given here. ) In the latter case ,the solar radiation heats up a ﬂuid that is used to drive a thermodynamic cycle. Total capacity grew by 29.3GW to reach 63.4GW. Solar radiation arriving at the Earth’s surface is a fairly dispersed energy source. One starts with a high accuracy value for the position (x, y, z) and the velocity (vx, vy, vz) for each of the bodies involved. {��!�+��J��͖ |��4�ǕRnN�{�$�':G-�H�x�y�v�]�|�C^ v The Physics of the Solar Cell Jeffery L. Gray Purdue University, West Lafayette, Indiana, USA 3.1 INTRODUCTION Semiconductor solar cells are fundamentally quite simple devices. If N is large (not so much in Solar System simulations, but more in galaxy simulations) it is customary to create dynamic groups of bodies. i Because of the solar source variation throughout the day, additional Thermal Energy Storage (TES) systems can be employed to store the energy surplus saved during the … 2 As a consequence the amount of calculation in the simulation goes up with the square of the number of bodies: Doubling the number of bodies increases the work with a factor four. x 2 In the previous section it was assumed that acceleration remains constant over a small timestep Δt so that the calculation reduces to simply the addition of V × Δt to R and so forth. . and then write out the factors f and g in a series. One of the simplest and most direct applications of this energy is the conversion of solar radiation into heat, which can be used in water heating systems. ! 8��{�+Xi�|8@�c7���K杧�.�` ��S i This equation describes the acceleration all bodies i running from 1 to N exercise on a particular body j. / <>/XObject<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 595.32 841.92] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>> The previous section looked at the energy output from solar across the world. x It is measured on a surface perpendicular to the rays, one astronomical unit (AU) from the Sun (roughly the distance from the Sun to the Earth)..
