<p>A solar charging system comprises solar cells, storage batteries, and a diode connected in series between the solar cells and the storage batteries, an anode of the diode being connected to a positive electrode of the solar cells, and a cathode of the diode being connected a positive electrode of the storage batteries, so that the solar cells directly charge the storage batteries, wherein a ratio of the number n of the solar cells to the number m of the storage batteries (i.e. n/m) is within a range of 3.5 to 4.0, and an internal resistance of the storage batteries is selected so that each solar cell outputs a voltage of 0. 36 to 0.5 Vundera standard light intensity condition. In the above solar charging system, the solar cells directly charge the storage batteries. Moreover, the above solar charging system has a simple configuration a high charging efficiency.</p> |
