- Future missions to Venus will require electrical power, but providing power systems that work in the high temperature environment of the surface of Venus is difficult. Power system choices include solar power from photovoltaic arrays, batteries, radioisotope power systems, and wind.

Oct 1, 2021 · Solar arrays are an attractive choice for a power system for a small Venus lander. Initial results show that, although performance is poor, it should be possible to use solar cells to produce power for a small landed probe on the surface of Venus.

of Venus, yet all have limitations that make them difficult or impossible to implement for a long life lander [7]. The potential options for power generation include: high temperature primary batteries, solar arrays, radioisotope power systems (RPS), wind power harvesting, and chemical heat sources, which are discussed below.
Oct 1, 2021 · The Venus environment makes electrical power systems for surface missions difficult. • Analysis suggests radioisotope power systems could be adapted to operate on Venus. • High temperature and low sunlight reduce power from solar arrays, possibly useable on small probes. •

VERITAS will have two solar array wings with three solar panels on each wing. The arrays will deploy shortly after launch and have a total area of just over 300 square feet (28 m 2). They will produce about 3,400 watts of power at the distance of Earth's orbit, and about 5,900 watts at Venus.
Another option that will not be explored is a solar array and battery combination because of the landing location at the North Pole. Although the use of solar arrays may be a feasible choice at the equator, 14 it is not a feasible

The Venus temperature also causes significant problems for operation of photo:voltaic devices. Solar cells decrease in performance as temperature increases, and at very high temperatures can experience catastrophic degradation. Existing solar cells work poorly at high temperature.
