On averate, very very cold. According to NASA, calculated temperatures range from a high of about +175°C at the orbit of Mercury (nearest the Sun) to a low of about −230°C (44 K) at the orbit of Pluto and lower still further out. The temperatures do rise if you enter the atmosphere of the planet but the volume of space occupied by the planets and their atmosphere is trivial compared to the near-emptiness within the solar system.
A solar hot water system uses solar panels to heat the water. Some advantages of using a solar hot water system is it uses renewable energy, and it lowers heating costs.
If there is no solar system, none of the planets will have daylight and we will never recieve the hot weather in the Summer.
