Voyager 2 carries two power sources to ensure redundancy and increase the chances of mission success. The spacecraft is powered by three radioisotope thermoelectric generators (RTGs) for electrical power and backup power is provided by its solar panels. This dual power source setup allows Voyager 2 to continue its mission even if one power source fails.
