“…Countries began to find a reliable and applicable source of renewable energy. Iraq is one of these countries where some governmental sectors depend on renewable energy [6][7][8]. Based on information gathered from the ministry of science and technology in Iraq -Baghdad, some ministries departments depend on renewable energy in addition to national energy [9].…”

Despite a sufficient energy supply, harvesting energy from rainfall is essential for intelligent water management. A significant part is still untapped or little exploited, which is the renewable energy produced from rainwater. This paper proposes a portable gutter of the rainwater energy harvesting system to provide electricity that may be sufficient for powering lights and charging cell phones in rainy locations with limited electricity. A prototype is designed and tested to determine the feasibility of rainwater as a source of renewable energy. The aim is to minimize and respectively suspend the use of fossil energy sources, as well as decrease the percentage of pollution as it is a cause of global warming. The system prototype consisted of a gutter assembly that collected and funneled water from the roof to a downspout. The turbine was connected through a gearbox to a DC motor serving as the generator. The device is optimal during high rainfall intensities that produce larger flow rates. A smart algorithm has been applied, which is salutary to keep the system working and has the ability to control the flow of collected rainfall water. Also, this system is useful to install and use in the rural area where the national grids are not common and the level of rainfall is high. The applied system utilized and installed in more than one hundred premises can produce more than 4 kWh for one rain. In some countries such as Malaysia, the average number of rainy days is 250 days a year, so the use of this system in 100 premises can help to provide 80 MWh to the national grid yearly. The system is characterized by simplicity of design and lack of complexity in addition to ease of installation and cheapness, which is the basis for the availability of this system for use by everyone

A new, easy‐to‐manufacture, and low‐cost integrated cubical solar collector tank for domestic usage is concerned in this work. Three models are prepared, side by side, and tested to point out their seasonal performance. Tank Model I has three vertical sides, black painted and glazed to act as an absorber; the other sides are insulated. Tank Model II has two black painted and glazed sides, with four insulated surfaces. The models are south‐oriented at different positions and tested versus the conventional tank (Model III) to validate and assess their performance in summer and winter. In summer, the temperatures in Models I and II are lower than those for Model III since they have insulated sides. Their glazed sides absorb a small amount of solar radiation since they are almost parallel to the incident solar radiation in summer. In winter, the water temperature in these models rises higher than that for Model III since their glazed sides work as solar collectors and have much lower heat loss to ambient. Therefore, the new design can provide a moderate temperature for summer and winter for residential use. Their water temperature does not exceed the ambient temperature at night in summer. It was higher than the ambient temperature in winter. The thermal efficiency for Models I and II in summer was 10.93% and 15.62%, respectively. While in winter, they were 15.09% and 19.46%, respectively.
