Solar energy system used for rural building

The invention discloses a solar energy system used for a rural building. According to the technical scheme of the solar energy system, the solar energy system comprises a house body, a solar water heater and a solar power generation system, wherein the solar water heater and the solar power generation system are arranged on a roof. The solar power generation system comprises a solar photovoltaic plate, a solar charging and discharging controller, a storage battery, an inverter, a direct-current load and an alternating-current load, all of which are sequentially connected. The solar energy system is characterized by further comprising a support used for supporting the solar photovoltaic plate and a photovoltaic plate traction mechanism. The solar energy system has the beneficial effects that design is reasonable, the structure is simple, solar energy is distributed and utilized more reasonably through the solar photovoltaic plate with the adjustable position, the solar power generation system and the solar water heater can be located in the same space, and the original functions of the solar power generation system and the solar water heater are not influenced; and in addition, the problem that aging of internal equipment is accelerated due to the too high water temperature of the solar water heater is solved.
