Abstract - This project explores a sustainable redesign of
solar technology into vehicle design, which presents a unique opportunity to harness the sun's energy to power vehicle systems.
vehicle sunroofs by replacing conventional glass panels with integrated solar panel systems. The aim is to turn the roof from just a part of the car into a surface that can collect solar energy and help power things like lights, the music system, air conditioning, or even charge the battery in electric and hybrid vehicles. The study focuses on the structural and mechanical feasibility of this transformation by replacing the traditional sunroof material with a lightweight plastic alternative. To evaluate its suitability, the natural frequency and stiffness of the solar roof were analyzed using both analytical and simulation methods. These parameters are essential to ensure the roof can endure vibrations and dynamic loads during vehicle operation. The findings lay the groundwork for future integration of solar technology and energy management systems in a structurally sound manner. We mainly focused on the strength and weight analysis. Simulations were carried out to see how well the roof can handle stress and how much weight it adds to the vehicle. The goal was to find a balance between being lightweight and strong enough for real driving conditions.
A sunroof is typically a movable panel on the roof of a car that allows light and fresh air into the cabin. Traditionally made from glass or metal, sunroofs were introduced to enhance comfort and style in vehicles. While they do not serve a functional purpose beyond passenger experience, their popularity has grown in both economy and luxury vehicles. Today, with advancements in materials and technology, this once simple feature holds potential for more practical applications such as integrating solar panels to generate clean energy for vehicle use.
1.2 Sunroof Market Growth and Dynamics The sunroof market has been a prominent segment in the automotive industry for decades, and it continues to evolve, driven by consumer demand for luxury features, improved driving experiences, and new technological innovations. In recent years, the market has been significantly influenced by trends in vehicle customization, rising consumer expectations for comfort and aesthetics, and an increasing emphasis on sustainability.

1.1 Brief Overview The automotive industry has long been a hub for innovation, with design and functionality continually evolving to meet the demands of consumers and environmental challenges. One of the earliest automotive design features that combined aesthetics and utility was the sunroof simple yet effective way to enhance the driving experience by offering natural light and ventilation. Over the years, sunroofs have become a common feature in many vehicles, offering both luxury and practicality. However, as global awareness of climate change and the need for sustainable energy sources grows, the automotive industry is now looking for ways to go beyond traditional features. One such innovation is the integration of
