Online Published on 14 February, 2024. Abstract The current study is based on the development of new solar heating system for biodiesel synthesis and other chemical processes. The solar system is developed by using satellite dish coated with aluminium foil (40°C–70°C). The second solar system was developed by using Fresnel lens (80°C–150°C) and the third system was developed by using large size Fresnel lens (70°C–120°C). These solar systems are suitable for those chemical reactions that require temperature within the range of 50°C–150°C. In our laboratory, these conditions are more suitable for biodiesel synthesis, extraction of carbohydrates and many other reactions. The solar oven can be used for combustion, reflux reactio ns, drying, evaporation, cooking etc. The purpose of the development of these systems is to transform all the conventional heating systems into solar heating systems because these systems are low-cost, renewable, carbon-neutral and environmental friendly. The development of this green energy technology will play a vital role in the laboratories of chemistry and related fields. The solar system will play a significant role in mitigating global warming, energy crisis, environmental pollution etc. Top Keywords Solar heating system, Satellite dish, Fresnel lens, Solar oven, Biodiesel.
