The invention provides a solar thermal collector system. The solar thermal collector system comprises a solar thermal collector and a heat utilization device. The solar thermal collector comprises thermal collection pipes used for absorbing heat of solar energy so as to heat water inside the solar thermal collector. The thermal collection pipes are metal thermal collection pipes. Each thermal collection pipe comprises a metal base pipe, wherein the outer surface of the metal base pipe is covered with an anticorrosive coating and a heat absorption coating in sequence. According to the solar thermal collector system, the heat absorption coating with high absorptivity is arranged, so that solar heat absorption capacity is improved. |
