A voltage quality module (VQM) function and a solar power generation function are integrated by sharing a single voltage converter 58 (VC) within the electrical system of an automotive vehicle with an electric-start internal combustion engine 54. The VC can be a DC-DC converter in a boost mode or a buck mode. A switching circuit selectably couples the VC between a main battery 51 and an accessory bus 55 or in between a solar panel 65 and an auxiliary battery 57. A VC controller 60 regulates a VC output using the main battery to stabilize an accessory bus voltage when in an engine crank mode and when not in an engine crank mode regulates the VC output to match an auxiliary battery voltage using the solar panel output.
