Countries close to the equator receive consistently strong sunlight, making solar panels produce more energy. For example, Indonesia's solar power collected at the equator could generate about 35, 000 terawatt hours (TWh) of solar energy per year, equivalent to the current global. . Vast arrays of solar panels floating on calm seas near the Equator could provide effectively unlimited solar energy to densely populated countries in Southeast Asia and West Africa. The main culprit behind this disparity is the angle of. . The Earth's climate is a solar powered system. Globally, over the course of the year, the Earth system—land surfaces, oceans, and atmosphere—absorbs an average of about 240 watts of solar power per square meter (one watt is one joule of energy every second). (NASA illustration by Robert Simmon.
