If you are away from home for a long time, the solar energy in your home needs some treatment to protect the safe and efficient operation of its equipment and systems, the following are some possible treatment suggestions:
- Unplug the solar panel power supply: when the solar water heater is not used for a long time, the first thing to unplug the power cord of the solar panel, which can avoid the solar panel to continue to consume electricity, and prevent leakage and safety problems.
- Empty the water tank: all the water in the water tank is discharged, so as not to freeze the water inside the water tank or breed bacteria due to long-term immobility, resulting in deterioration of the water quality, and leakage, burst and other accidents.
- Cover the solar panels: In order to prevent the solar panels from being seriously damaged when leaving home for a long time, you can use a sun screen or rain cover to cover the solar panels, which can prevent the solar panels from direct sunlight and rain erosion.
- Clean the solar water heater: Before leaving home, you can clean the solar water heater, including the solar cell body, pipes, construction state, heat collector water channel/drainage hose, etc. This can effectively avoid the accumulation of debris, find professional help when moving, and check the status of supports, vacuum tubes, water tanks, overflow pipes, pipelines and other components every year.
5, ensure that the solar panel clean: long-term exposure to the sun, the surface of the solar panel will accumulate dust and dirt, if not cleaned in time, will affect the photovoltaic conversion efficiency of the solar panel, but also affect its service life. You can use a soft cloth and mild detergent to clean the surface of the solar panel, and ensure that the water used throughout the process is clean, so that the residue will not cause corrosion to the solar panel.
- Vacuum tube maintenance: In the case of not using for a long time, you can regularly turn the valve hand wheel to prevent water pipe blockage. When checking the vacuum tube, pay attention to whether there is obvious damage or loosening, if any problem is found, it needs to be repaired or replaced immediately.
In the above treatment measures, regular maintenance and cleaning is the most important and most troublesome step, which can ensure the safe and efficient operation of solar water heaters, avoid leakage, burst and other accidents. If you are away from home for a long time, we recommend that you choose to take your solar water heater to a professional solar system maintenance provider or engineer for maintenance and maintenance. At the same time, for solar water heaters without reliable lightning protection grounding, it is absolutely prohibited to use in thunderstorm weather. Choosing high-quality solar panels, such as the monocrystalline silicon solar panels from Ifi Solar, ensures the reliability and efficiency of clean energy solutions.
