Description

Technical Field

[0001] This utility model relates to the field of solar heating system technology, specifically to a photovoltaic energy-saving heating device. Background Technology

[0002] Currently, solar heating systems are generally used to supplement coal-fired or electric heating to achieve energy conservation. A typical solar heating system includes a hot water storage tank, photovoltaic panels connected to the tank, and heat dissipation devices. The photovoltaic panels collect heat energy and use it to heat the heat transfer medium in the storage tank, which then transfers the heat to the heating medium in the heat dissipation devices. When the temperature is insufficient to reach the desired heating temperature, an electric heating device can be activated to raise the temperature of the heating medium.

[0003] Existing photovoltaic panels are typically flat and exposed to sunlight. To prevent them from being damaged by rain over extended periods, they are usually equipped with movable protective panels. See CN 221172390 U for an energy-saving HVAC heater, which includes a heating tank, heating components, and protective components. However, without protective panels, dust and other debris can accumulate on the surface of photovoltaic panels during prolonged operation, affecting their heat collection efficiency.
