Solar energy is most admired alternative to traditional energy sources. Special attention is required to improve solar gathering techniques in mountainous regions like Sikkim, where sun availability is unreliable but irradiance level is high. This paper proposes a hardware model for smart autonomous selfadjusting solar panel whose output is fed to DC-DC Cascaded SEPIC-Boost Converter for high voltage renewable based applications. The developed renewable system is designed to adjust the panel in a position where maximum voltage is extracted. The output of the solar panel is fed to the DC-DC cascaded converter. A detailed circuit analysis is performed to evaluate the system's e ciency and voltage gain. The converter is examined with different duty cycles. The proposed converter generates 40 V DC output with 20 V DC input voltage from solar panel at 50% duty ratio and gives 90% e ciency. The feasibility of the converter is con rmed with results obtained from an experimental prototype.
