Radioisotope thermoelectric generators
so far the only way to create electricity is with solar panels
It would be great if there were RTGs to create electricity with a nuclear power source that slowly runs out. They could be customised by changing the nuclear fuel and higher power output in exchange for faster depletion of the fuel

electric power of "Yenisei" - about 4.5-5.5 kW. The sodium-potassium melt was used as a heat carrier.
In November 2017, in the US, at the Glenn Research Center [ru], tests began on a demonstration prototype of the Kilopower reactor power plant designed to generate electricity with an output power of up to 10 kW and a service life of 10 years on the surface of Mars

it's a pity that only solar panels are from the sources of electricity ... for now
initiated the creation of Russian space solar power plants (CSPS) with a capacity of 1-10 GW
Radioisotope energy sources are used mainly in the following cases:
long flight duration;
missions to the outer regions of the solar system, where the solar radiation flux is small (Cassini-Huygens, New Horizons, etc.);
reconnaissance satellites with side-looking radar, due to low orbits, cannot use solar panels, but they have a high demand for energy -

my suggestion, it turns out that even 1 ion engine needs more than 612 solar panels ...
