The Smart Solar Tree is an eco-friendly, creative piece of urban furniture that can function as a six-person public bench, a supply terminal block with six 230V power outlets for laptops and electric bicycles, a built-in USB charging hub for smartphones and tablets, and a fashionable tree-shaped public lighting fixture. Eighteen solar photovoltaic panels, which function as programmable-color glowing leaves at night, provide the Smart Solar Tree with its whole electricity. Because establishing solar trees required less than 30 square feet of land, and installing ground-mounted solar panels required 5000 square feet, the results were compared to solar panel installations. The energy, financial, and environmental performance of solar PV systems was also examined in this article. The 5 kWp solar tree costs USD 1700 in total, compared to $2500 for flat-mounted PV. The solar tree's payback period is projected to be 10 years. Solar trees cost 0.07 USD per watt, compared to 0.11 USD for standard photovoltaic systems.
