Yes.
Under normal circumstances, if the solar water heater is full and overflows, it will not cause damage to the solar water heater. However, if the solar water heater tank is damaged and water leaks into the insulating layer of the tank, the solar energy will be scrapped. In this case, you can only contact the buyer to replace the water tank.
Solar water heaters convert solar energy into thermal energy and heat water from low temperature to high temperature to meet people's use of hot water in life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat panel solar water heaters based on their structural shapes. Evacuated tube solar water heaters are the main ones, accounting for 95% of the domestic market share.
Detailed information:
1. If an auxiliary heat source is installed, the auxiliary heat source device and heat exchanger should be checked regularly to see if they are functioning properly. For auxiliary heat sources heated by electric heating pipes, you must ensure that the leakage protection device works reliably before use, otherwise it cannot be used. When using the electric auxiliary heater, special attention should be paid to filling the water. The volume of water in the water tank should not be less than 50% to avoid dry burning without water. When taking a bath, pay particular attention to unplugging the power plug, and it is strictly prohibited to use it when the power is on.
2. When installing heating tapes, be sure to choose products ofacceptable quality to ensure normal use and reduce hidden dangers. When using the heating tape, be sure to turn it off promptly after defrosting, and try not to use it when the voltage is unstable.
3. How windy is it in winter? Solar water heaters are installed outdoors. Therefore, the water heater and roof must be installed securely to withstand strong winds. In windy weather, the solar water heater can be filled with water to increase the wind resistance and bearing capacity of the water heater, and the electric heating, instruments and other power sources can be disconnected.

Should it be used separately or at the same time?
In isolation, it's relatively simple. Mechanics can make an electric car, weigh, etc., optics can make image of small holes, and the thermal is more annoying.
If you need to use it at the same time, you can make a Stirling engine, which converts thermal energy into mechanical energy and uses both thermal science and mechanics. There are also solar-powered Stirling engines. Internet, which can all be used, but it is difficult to achieve. You can try making a simple Stirling engine, just use a can of internet search to find specific tutorials and you should be able to figure it out.
I hope this helps you.
