    Solar energy is one of the important sources of renewable energy which can be a feasible alternative to fossil fuels. There are many works done in order to incorporate solar energy to everyday transportation including tricycle. However, most of the tricycle developed are expensive and not feasible for developing countries. In this study, a cheaper solar tricycle with more capability of utilizing the solar energy is designed for developing countries. The main problem identified with the existing delta model (2 wheels at rear and 1 wheel in front) for tricycle is low dynamic stability, inefficient braking and poor aerodynamic suitability. Hence a tadpole model (1 wheel at rear and 2 wheels in front) is proposed in this existing study. The model is made to a system in which the power can be obtained from the solar energy . The energy can be obtained externally as a backup when the solar energy is not available. The outcome of this project is a tricycle with a better design and ergonomically well suited for a physically challenged person. Tadpole design will provide better dynamic stability which will avoid slipping of the vehicle and will provide better weight distribution to the vehicle. It will also provide better braking mechanism as tadpole design has two tyres in the front where the weight transfers when decelerating. The tadpole design lends itself better to the aerodynamics tear drop with the correct length to width ratio.
