This study primary focuses on understanding customer preference and attitude towards the usage of solar products and solar energy in Namakkal City. Solar energy one of the most promising forms of renewable energy, can be harnessed in two principal ways: First, through the direct conversion of sunlight into electricity using photo voltaic (PV) technology, and second by utilizing solar thermal system to generate power. Both approaches contribute significantly to clean energy production, offering an environmentally friendly alternative to energy is entirely renewable, abundantly available, and does not produce air pollution or toxic waste during its generation process. Furthermore, solar power system operates silently, ensuring that no noise pollution is created while capturing or converting or converting sunlight into useful energy. The global demand for solar electricity has been increasing rapidly, rising at an estimated rate of 40% annually. This growth is largely driven by consistent technological advancements, declining manufacturing costs, and the overall reduction in market prices for solar equipment over the past two decades. As a result, solar energy has become more accessible and cost-effective for both residential and commercial consumers. Solar technologies can generally be categorized into positive and negative systems based on how they capture, store and distribute solar energy. Passive systems rely on architecture design and materials to naturally absorb and utilize sunlight, while active systems employ mechanical or electrical devices to enhance the collection and conversion of solar power.
