The world is facing a huge energy crisis due to resources depletion. The renewable energies play a vital role in energy generation sector. Fossil fuels such as coal and oil cause enormous environmental pollution. Wind energy is a major renewable source of energy and can replace this fossil energy. This paper aims to study the energy generation methods using roof ventilators. A wind driven, having metallic construction and blades on its periphery is a roof top ventilator. It is installed on the roof of industries as well as machine shops, warehouse and it provide effective ventilation. Hot air becomes lighter and goes upward on the top of industries and is expelled out through ventilator. At the same time fresh air also suck inside due to free spinning of roof ventilator. This free spinning can be converted into electrical energy using different electrical components. This technique is low in cost and feasible because of the minimum quantity of transferring elements and electric systems.

“…Ventilation can be increased using ventilators in combination with natural ventilation. Frequently utilized in buildings, warehouses, and occasionally manufacturing plants, ventilators are used to regulate and condition the air, producing electricity effectively [60]. Their operation is influenced by wind and heat pressure, factors directly linked to air temperature, relative humidity, and airflow rate.…”

The efficiency of solar photovoltaic (PV) power generation is significantly impacted by factors such as ambient temperature, surrounding wind speed, and the temperature of the solar PV panels. The power generation efficiency of these panels diminishes by approximately 0.5% for each incremental rise in their temperature. To mitigate this effect, two primary methods for cooling solar photovoltaic panels are considered: active and passive cooling techniques. This review paper delves into an extensive body of literature on solar passive cooling systems, highlighting the vital role of passive cooling technology in enhancing the efficiency of solar PV power generation. We investigate the structure and cooling effect of diverse passive cooling systems, with a specific focus on the application of solar chimneys and ventilators in cooling systems for solar PV panels. Our study reveals that solar chimneys, using buoyancy, can decrease the temperature of solar PV panels by as much as 15 degrees, thereby augmenting power generation efficiency. Furthermore, the deployment of ventilator technology can boost the efficiency of solar PV power generation to an impressive 46.54%. In conclusion, this paper proposes the synergistic use of solar chimneys and ventilators to improve solar PV panel efficiency, extend their lifespan, and reduce the environmental impact resulting from inefficient solar PV panels. This comprehensive approach should inform future practices.

“…Some of them are concentrating on the influence of height [6] or diameter [8], [9] on performance of the ventilator, the others -on different constructions and/or blades [10] or actual applications in buildings and improvement of IAQ [11]. Newer tendencies of research in the field of RTV are related to additional benefitsproduction of electricity using RTV [12], [13] or exploitation of solar energy to increase the efficiency of the device [14], [15]. Also, some studies show that wind driven ventilators can play an important role in the design of a cost effective and energy efficient ventilation system inside a building as they have low cost, require no maintenance and no electricity to run [6,8,11].…”

Ventilation systems using renewable energy enable to reduce electricity demand. However, their operation directly depends on the stability of the renewable energy source. In this study, the wind driven roof turbine ventilator (RTV) is analysed. As a rule, this equipment is selected based only on the average annual wind speed and there exists a lack of date related to functionality of RTV. The case study presented in the paper seeks to assess functional operation of the RTV within the whole year. Simulations, performed with TRNSYS software, are based on the empirical equation for the ventilation flow rate extracted by the tested turbine ventilator. Results provide the number of RTV operational hours and share (%) of the time, when the RTV operates. Most of the time RTV operates at partial required load, however, there are periods when air flow rates are excessive and this should be considered as storage potential. The presented results could help to determine more accurately functional operation of RTV in the selected room/building and estimate demand for additional ventilation solutions as well energy storage potential.
