“…While determining the optimum tilt angle for Canada, Hailu and Fung [14] concluded that the isotropic model gave lower tilt angle estimates relative to the latitude of the location, compared with slightly higher tilt angle estimates for the anisotropic model. Similarly, the anisotropic model achieved a higher tilt angle for various locations in India [15]. Shukla et al [16] performed another study in India using three isotropic and three anisotropic models.…”

Estimation of solar radiation distribution is crucial for the performance, design, and economic evaluations of solar panels and/or collector systems operating under various climatic conditions, tilt angles, and geographic locations. A comprehensive study involving the combined effect of tilt angle as well as ambient temperature for maximizing the PV array power output was performed. At first, we present a comparison between different isotropic and anisotropic models showing that the anisotropic model gains 5% more energy than the isotropic one. We report monthly and yearly optimum tilts derived from the anisotropic model. Utilizing the optimum tilt derived from the selected anisotropic model, a case study of a monocrystalline silicon PV array with 2.76 kWp of the rated power is carried out to evaluate the PV performance in five cities of the Kingdom of Saudi Arabia. The results show that the estimated yearly optimum tilt angle is close to the latitude of the studied cities. For the city of Dhahran, a gain of 4.2% power generation is achieved at ambient temperature through monthly adjustment of the PV module instead of yearly adjustment. The estimated yearly tilt angles are as follow: 27.3 • for Dhahran, 26.0 • for Riyadh, 22.7 • for Jeddah, 32.7 • for Arar, and 20.1 • for Abha. Although Riyadh and Arar receive the same annual average GHI of 6.0 kW/m 2 , the yearly average PV power output is ∼7.1% higher for Arar (1.50kW) compared with Riyadh (1.40 kW). This is mainly attributed to the fact that Riyadh has a higher annual average ambient temperature of 29 • C compared with 23 • C for Arar. Thus, in addition to panel orientation, the ambient temperature was found to have a significant impact on the performance of the PV system and should be taken into consideration when designing the system.

“…The tilt angle (TA) has an impact on dust deposition on PVs, and the TA and tracking system work together to maximize incidence SR on PV surfaces [7,8]. In the literature, incident SR on a horizontal surface for Indian cities is presented [9,10] however, it is restricted to inclined surfaces [11][12][13][14]. Under various tracking settings, Fahl et al [15] calculated OPTA for Bangalore as 12.96 for Bangalore, India.…”

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.

This paper deals with finding of optimum tilt angle for installation of optimized solar photovoltaic system in India. The optimization of tilt angles is performed using measured solar radiation data for 26 cities in India. The tilt angle is changed from 0°to 90°at step of 1°to find out optimum tilt angle for which monthly average solar radiation is maximum. It was found that the optimum tilt angle varies between 0°and 63°t hroughout the year in India. The monthly optimum tilt angle is maximum in December for all cities in India. It is found that increase in maximum solar radiation at monthly optimum tilt angle in comparison to latitude based tilt angle and annual optimum tilt angle varies from 5.85% to 8.08% and 5.95% to 8.34%, respectively, showing monthly optimum tilt angle is beneficial for maximum power generation for different cities in India. The novelty of this study is new correlations of optimum tilt angle in terms of extraterrestrial radiation are developed for estimating monthly optimum tilt angle for installation of photovoltaic systems at different sites in India. The root mean square error in correlation equations varies from 0.1256 to 0.9771.
