Solar energy is widely considered as a primary form of Green Energy because it generates electricity and heat without polluting the nature and separating it from the fossil fuels and resulting in the Solar energy as Sustainable Technology. This research paper mainly focuses on solar panel preparation, design, and performance analysis of a low-cost solar panel using the photovoltaic (PV) cells suitable for the small-scale application like domestic energy requirements. Our research mainly emphasizes the comparative study of the solar cell. Testing of solar panel was done under various circumstances and I-V characteristics, Fill Factor are studied. Taking all the things into consideration, the final result indicates that the low-cost solar panels can generate the feasible amount of electrical energy through which small household devices such as fan, light bulb, or other devices, can be run on the basis of the solar panel. This contributes to better energy management and promotes the advancement of sustainable technologies and focuses on high use of renewable energy sources for the human mankind and future.
