Abstract
Rooftop standalone solar technology is a new renewable power generation solution worldwide and can reduce carbon dioxide levels in the environment. However, several factors affect the performance of the power plant, it is highly influenced by weather parameters. This paper shows the design of the rooftop standalone solar power plant and the influence of temperature, light intensity, and environmental humidity on it. The designed system consists of a 200WP photovoltaic, 1260Wh LiFePO4 battery, and an MPPT solar charge controller 40A. This standalone power plant was applied to supply the energy of the home lighting, with 20Watt the total of power. The result shows the design of the rooftop standalone solar power plant. Furthermore, there is an influence of temperature, light intensity, and environmental humidity on the LiFePO4 battery input power.
