“…To estimate the electricity demand, a comprehensive hourly load data profile for an entire year is required. Site details, such as a load profile for regular household consumers and the time of use of electrical appliances, are the key requirements for the design of the PV system (AlShemmary et al, 2013). Using a field observation approach, the prevalent electrical equipment and duration of their use in the studied house types are identified.…”

Solar power through the use of photovoltaic (PV) system is the most advanced and profitable renewable energy application; however, there are still a number of obstacles facing this technology, including technical, financial, and political barriers. According to meteorological data of Iraq, the annual average solar radiation is about 1800-2390 kWh/m 2 /year, which is a considerable amount of energy if properly utilized. This study proposes a design model of PV installation system and the model is applied to three different PV systems for installation in a residential household in Erbil, Iraq. The study examines the feasibility of the plants proposed and compares the efficiency of both fixed and tracking PV systems for an off-grid PV system. The PVsyst software is used for household electricity load estimation and solar energy requirements, such as the appropriate number of panels, maximizing AC power generation, the storage capacity of the battery, and charge controller size to fulfill the required load. To calculate the annual energy generation, the design data was used in the simulations. Three scenarios were simulated; fixed panels, East-West single tracking, and dual-axis tracking systems based on the altitude and azimuth tracking angles. The study compared both the photovoltaic properties and the amount of energy generated by the installed systems. The results showed that the dual-axis tracking system is 30% and single-axis tracking system is 21% more efficient than the fixed PV system, although the latter offers an economically better alternative.

“…The battery's voltage is dependent on the solar module configuration, which is between 12 and 48 volts, and the total number of amps. According to AlShemmary et al (2013), the simplest relationship used to determine the size of batteries or battery banks for a certain load demand is expressed in Equation 6:…”

“…It is also important to consider that effective component sizing ensures a reliable, proper and economical design [20]- [23]. Monitoring the performance and loss factors of PV systems is important to assess overall efficiency and to enhance productivity [24], thus a successful implementation of solar PV systems involves knowledge on their operational performance under varying climatic condition [25].…”

This article is the product of the investigation "Development of a photovoltaic pilot system for performance assessment of isolated systems in the Renewable Energy Laboratory at UNAB" developed at the Universidad Autónoma de Bucaramanga (UNAB) in 2019, considering off-grid solar home systems (SHS) are a feasible alternative in rural remote areas, where access to electric power is limited due to their power grid lack. The objective is to develop a PV test system for off-grid solar home system (SHS) performance assessment. For the development, a case study is analyzed based on the behavior of a user's daily demand in Hato Corozal, Casanare. Design aspects of the system are also elaborated. Key performance parameters identified to be monitored are solar irradiance, power generation, energy consumption and battery charge status. Two scenarios of daily demand behavior are analyzed to evaluate the influence of load shifting on the performance of the system. The applied design criteria were validated obtaining that the sized system satisfied the energy requirement without a battery’s depth of discharge (DOD) deeper than specified, showing the capacity of the system to make studies in longer periods with the possibility of generating different demand behavior scenarios. The designed system presents a performance ratio of 0,77 when a daily consumption is considered, while when shifting loads to coincide them with the higher irradiance the PR was 0,95. In both cases, the SoC was higher than 79%, maintaining a DOD of the battery bank according to the specified in the sizing. The system presents excess energy that can be used by expanding the capacity of the battery bank. Findings suggest that a higher performance ratio is obtained when coinciding consumption peaks with the hours of higher solar radiation.

“…Currently, around 80% of the total energy demand is met by non-renewable sources, especially fossil fuels (Acar and Dincer, 2014). The world's fuel supply has been disturbed significantly in recent years due to the COVID-19 pandemic and disputes among countries.…”

The world’s primary energy demand has increased significantly due to the industrial revolution and population growth, which create the demand for primary energy. The COVID-19 pandemic situation significantly damages the world’s energy network, which critically affects developing countries like Sri Lanka. Therefore, this paper has been developed to discuss an important framework for the use of solar energy as a suitable energy source for various industrial operations. The application of solar thermal energy and solar PV systems into industrial processes can minimize the economic cost of energy usage in the country. The points discussed in this conceptual mini-review can help policymakers identify and explore industrial windows that can be structured with solar energy for a sustainable energy future in Sri Lanka.
