Evaluation of the Existing Solar Energy and Rainwater Potential in the Total Roof Area of Buildings: Izmit District Example

Abstract

In this research, an exemplary study has been conducted in order to draw attention to the importance of evaluating the existing potential on the roofs of buildings. This research offers an evaluation of the existing solar energy and rainwater potential on the total roof area of the buildings in the Izmit district, which is a central district of Kocaeli province, one of the busiest centers of industry in Turkey. The calculations in this study were carried out by using the data obtained from various institutions. As a result of these calculations, the ratio of electrical energy that can be provided with photovoltaic systems on roofs to meet the annual electricity consumption of the district was found to be 203.581%, and the annual solar energy utilization rate for a family of 4 to bring 240 liters of daily use water temperature to 60°C with an 8 m2 collector area was calculated as 66%. In addition, the ratio of rainwater that can be collected from the total roof area of the existing buildings in the district to meet the domestic water consumed by the district was found to be 33.27%.

Multivariate Analysis of Harvested Rainwater Quality Utilizing Sustainable Solar-Energy-Driven Water Treatment

“…There is an urgent need to investigate novel strategies that not only purify accessible water sources but also lessen the carbon footprint of treatment operations, as water scarcity and contamination continue to pose a threat to conventional water-delivery systems [21][22][23]. Utilizing solar energy and rainwater treatment together offers a creative solution that emphasizes resource saving and encourages the delivery of clean and potable water [24][25][26][27][28]. The foundation of public health and wellbeing is the quality of drinking water, which is closely related to overall life quality and the prevention of waterborne diseases [29][30][31][32][33][34].…”

“…An indication of humanity's desire to use nature's rich resources without upsetting its delicate balance is the use of solar energy in the context of rainwater treatment. The strategy harmonizes with resource optimization and environmental conservation tenets by utilizing solar energy's renewable and sustainable qualities [26,[35][36][37][38][39][40]. Solar energy's ability to power and improve each stage of the treatment process from collection to disinfection enhances the very nature of rainwater treatment, which takes advantage of the Earth's natural water cycle.…”

An impact of solar PV specifications on module peak power and number of modules: A case study of a five-bedroom residential duplex

“…According to Wang, Liu, Wang, Zhu, Liu, Lin and Li [11], the growing use of solar PV systems is contributing to the fossil fuel crisis resolution and drive the optimization of energy structures. Africa is generally known for its low access to energy but is endowed with an abundance of high solar irradiation with the potential to be utilized to meet its energy needs [12,13]. Nigeria in particular receives high levels of solar radiation throughout the year.…”
