Unlike (the now crashed) Luna-25 lander, CH3 does not have a Radioisotope RTG that can provide heating and power during the lunar night.

Given that Chandrayaan-3 is at 69.37° S latitude, the maximum elevation is around 20°. Hence the near-vertical orientation of the solar panels on the lander and the rover. The Sun will disappear below the horizon and the mission will come to an end around Sep 4.

ISRO mission brochure; i.e. no Radioisotope thermoelectric generator (RTG), only 738 W solar panels
