Flat single-axis photovoltaic brackets are suitable for low-latitude areas. They usually track the altitude angle of the sun to increase the vertical component of the sun's rays on the battery panel to increase its power generation. There are north-south axis tracking and east-west axis tracking. East-west axis tracking has no obvious advantages over fixed tilt installation, and the north-south axis tracking effect is better than east-west axis tracking. Flat single-axis photovoltaic brackets have one axis that automatically tracks the sun in the east-west direction every day. The structure is simpler, the assembly is clever, and the terrain adaptability is strong. The rotating parts are made of stainless steel, maintenance-free, and have a design life of more than 25 years. In low- and middle-latitude areas, the investment is increased by about 5-8%, while the power generation is promoted by 15%-25%, bringing more returns to investors.
