Solar energy is the most abundant renewable energy source. This energy can be converted directly into electricity using solar panels. The fixed tilt solar panels are the most practical and the most widely installed throughout the world. Optimum tilt angle calculation has the advantage that it does not use expensive solar trackers. This research calculates the seasonal optimum tilt angle of solar panels for 17 cities in Iraq and 83 cities in 83 countries distributed around the world. Solar Panel Angle Calculator program was used in calculating the optimum tilt angles from vertical. The optimum tilt angle varies between 6° and 112° throughout the year. This angle for winter, spring/ autumn and summer seasons are found to be between 6° to 66°, 30° to 89° and 54° to 112°, respectively. All angles calculated from the calculator program are validated by comparing it with those obtained from equations. An excellent agreement was established. Cities which have approximately the same absolute values of the latitudes are have the same optimum tilt angles. Based on the results, adjusting angles four times a year is recommended. This work can serve as a guidance for installing solar panels.

“…Solar power, nowadays, is the most promising type of non-conventional source of energy. In Egypt solar energy is used on a small scale in some applications; although it has high values of solar radiations (Bagher, Vahid, & Mohsen, 2015) and sunshine hours (Sumathi, Kumar, & Surekha, 2015). Solar energy can be used in different schemes such as: thermal applications and photovoltaic applications (PV) (Ranabhat et al, 2016).…”

The Egyptian government has set renewable energy targets of 20% of the electricity mix by 2022 and 42% by 2035. The National Water Research Center (NWRC) (Qanatir, Egypt) set up a pilot rooftop 90 kW PV system supporting this approach. This paper analyzes the electrical output signals of 90 kW photovoltaics on-grid system mounted on the roof of the National Water Research Center (NWRC) (Qanatir, Egypt). A previous simulation model using Matlab program is modified to incorporate more accurate information on system configuration became available. Components of the model were modified: four inverters (20 kW rated power) and one (10 kW rated power) and the scenario of tying the system to the local low voltage grid is discarded. Recommendation from previous study was taken to tie system the national high voltage grid to multiply the savings; therefore, it is the only simulated scenario.The simulated output energy of the system, at different values of solar intensity, is compared with the recorded data. A deviation between the simulink model and recorded data is found, due to power failure, surface cleaning of PV panels and weather variations. The results showed that the maximum energy is generated during July (14.5 MWhr) whilst the minimum energy in December and January (5 MWhr).

Summary Dynamic power sharing among various electrical sources is a primary requirement for grid‐connected solar energy conversion system with battery storage facility (called as physical system). In this regard, adaptive solar module– and battery characteristics–based decision‐making program package is developed to guide power management activity under different dynamic operating conditions. Various multifeatures are also imposed in the package as prediction of solar condition, load forecasting capability, future generation scheduling ability, measurement of voltage flicker, and output harmonic level of solar inverter, secured communication for facilitating coordinated operation, etc. Thus, many practical issues are implemented in the package for real‐time testing of the integrated system in large‐scale under common platform, which is not noticed in published papers. Here, various codes using C# language are written in the package. The charging and discharging characteristics of battery can influence power management activity. Also, charging and discharging rate of battery can decide the life of the battery. Thus, adaptation of modified charging and discharging characteristics within power management package is proposed to cope with changed profiles of battery with its age. In addition, updating facility of solar characteristics is incorporated in the package for achieving more accurate solar prediction capability. Furthermore, real‐time compatibility of developed package with physical system model in MATLAB‐SIMULINK platform promotes research and development activity. Dynamic performances of developed package and its notable features are verified through real‐time experiments in conjunction with MATLAB‐SIMULINK software–based model of aforementioned physical system using internet‐connected multicomputer system.
