I think it is good to install a relatively large solar water heater. It can be used as a water storage tank and does not consume energy as long as there is sunshine, it can generate hot water for bathing and other uses. It's very useful. If you only install a water storage tank, there is no need to install a pump, because the water pressure on both stages is certainly sufficient, but you need to install an automatic water heater, which can automatically turn off the water. water when the water is full. The price/performance ratio is significantly better with a solar water heater, which has 200 liters of solar water, if you use electricity to heat the water from 20 degrees to 50 degrees, it will consume 7 kilowatts. hours of electricity, and the electricity bill will be around 4 yuan. However, solar water heaters do not need to be turned on when the sun is shining, and the temperatureof water will be higher if your home wants to use hot water. water, you'd better install a solar water heater.
You need solar panels (silicon panels) and photovoltaic submersible pumps. The workflow is as follows: Install the silicon panels on the roof (Chaoyang), the circuit is connected to the photovoltaic submersible pump (the height of the submersible pump should exceed the depth of your deep well). Use a pipe to connect the water outlet of the submersible pump to the water cylinder (or water tank). The tank is placed on the roof and there is a water outlet at the bottom of the water tank. Just connect it to the kitchen with a hose.
