The invention relates to a low-power solar equalization charging system. The low-power solar equalization charging system comprises a control module, a current equalization device connected with the control module and two storage batteries, the current balancing device comprises an electric quantity detection module, two photovoltaic panels and two electric control rheostats, the two photovoltaicpanels are connected in parallel and then are connected with the electric control rheostats respectively, and the electric control rheostats are connected with the corresponding storage batteries respectively. When the electric quantity of one storage battery is larger than that of the other storage battery, the control module controls the electric control rheostat connected with the storage battery with the large electric quantity to increase the resistance value, so that the charging current of the storage battery is reduced, and the electric quantities of the two storage batteries are balanced. And / or when the electric quantity of one storage battery is larger than that of the other storage battery, the control module controls the electric control rheostat connected with the storage battery with the small electric quantity to reduce the resistance value, so that the charging current of the storage battery is increased, the electric quantity of the two storage batteries is balanced,the utilization rate of electric energy is increased, and the service lives of the storage batteries are prolonged.
