It costs around 1,800 yuan and the price varies depending on the amount of energy produced. Generally, it can provide electricity for lighting for a family of three and can be used for a few hours on a computer.
Solar water heater is a device that converts solar energy into thermal energy, heating 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 mainly used, accounting for 95% of the domestic market share. Household evacuated tube solar water heaters are composed of heat collecting tubes, water storage tanks, brackets and other related parts. Converting solar energy into energyThermal energy is mainly based on vacuum heat collector tubes which use the principle of hot water floating. and cold water flows to cause microcirculation in the water.
Solar water heaters are free if heated by sunlight. If solar heating cannot reach bath temperature, use an electric space heater. The electricity used is the same as that of the electric water heater, and the electricity consumed per kilowatt hour is the same as the electricity used to light your home (civilian electricity price). ).
The electric heating power of solar energy is generally 1.5 kilowatts or 2 kilowatts. That is, when the electric heating is turned on, it is 1.5 degrees or 2 degrees of electricity per hour.
