The Mariner 1 power system consisted of the two solar cell wings, one 183 cm by 76 cm and the other 152 cm by 76 cm ( with a 31 cm dacron extension ( a solar sail ) to balance the solar pressure on the panels ) which powered the craft directly or recharged a 1000 Watt-hour sealed silver-zinc cell battery, which was to be used before the panels were deployed, when the panels were not illuminated by the Sun, and when loads were heavy.
