No. Solar water heaters can be used for solar power generation, but photovoltaic power generation specifically refers to the production of power by solar cells.
Solar water heaters are devices that use sunlight to heat water.
Photovoltaic power generation is based on the principle of photovoltaic effect, using solar cells to directly convert solar energy into electrical energy.
The production of electricity by solar water heater and the production of photovoltaic energy are very different from the principle to the equipment. Besides electricity production, their biggest similarity is in the location of solar collection units.
The biggest feature and advantage of photovoltaic power generation system is that "electricity" can be obtained directly by using groups of solar cellses, and the use of electricity, both in technology and equipment, is already very mature. At present, the main technical obstacle lies only in the conversion efficiency of solar panels (how to use fewer panels to produce more electricity).
Using solar water heaters to produce electricity. In fact, it uses low temperature hot water produced by solar water heaters to produce electricity. Many attempts took place before photovoltaic power generation was widely adopted. But until now, there is no solution to reach the level of photovoltaic energy production in terms of performance and profitability. The image below is a diagram of a low temperature hot water power generation device. The general process is: use hot water to heat the working fluid (fluide work, such as ammonia), the working fluid evaporates to produce steam to drive the steam turbine, and the steam turbine drives the generator to produce electricity. There are multiple thermal-thermal, thermal-mechanical and mechanical-electrical conversions. Therefore, when the scale does not reach a certain level, the structure and cost are much higher than photovoltaic power generation. This is much less practical than photovoltaic power generation, which can be adapted to local conditions and come in any size.
We can wet a towel and put it on our body to help us cool down, or we can take a shower directly, this way the water will carry away heat and the body human. will be much cooler. If your family is unfortunately losing water, it goes without saying that you need to open the windows for ventilation. Don't trymaintain the cool temperature you had before the power outage. A ventilated environment will always be cooler than a place where air circulation is stagnant. If that doesn't work, you might as well go out for a walk. The temperature at night is much lower than during the day, and the human body is also more adapted.
