No.
Solar panels are not fragile. They are made of strong tempered glass panels and have passed the hail test.
Solar panels are power generation devices that convert light energy from the sun into electrical energy, then produce direct current and store it in the battery.
The reasons why solar energy is generally placed obliquely: 1. The surface area of the water heater is limited, and the sunlight is irradiated at an angle to the ground plane. Therefore, in order. To maximize the illuminated surface, the solar water heater is installed obliquely. 2. Solar water heaters are made of glass tubes and are most susceptible to hail. Generally, hail falls in the direction of Earth's gravity, that is, perpendicular to the ground. A water heater installed at an angle can reduce the affected area. the attack, and at the same timeemps, it can reduce the vertical impact The effect of force. 3. A simple solar water heater placed at an angle receives the most heat and has the highest water temperature.
The solar water heater is a device that uses sunlight to heat water. Solar water heaters are divided into vacuum tube solar water heaters and flat panel solar water heaters which account for the majority of the domestic market share.
The principle of solar water heater
The solar water heater converts solar energy into thermal energy, heating water from low temperature to high temperature to meet people's daily needs. , the use of hot water in 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%from the domestic market. Household evacuated tube solar water heaters are composed of heat collecting tubes, water storage tanks, brackets and other related accessories. The conversion of solar energy into thermal energy mainly relies on heat collecting tubes. The heat collecting tube uses the principle of hot water floating up and cold water flowing down to cause microcirculation of water to achieve the required hot water.
Classification of solar water heaters
1. Solar water heaters with glass evacuated tubes
The most. those commonly used are all-glass vacuum tube type, especially solar water heaters with auxiliary electric heating function, which use solar energy as the main source and are supplemented by electric energy, enable heating -solar water to operate normalment throughout the year and around the clock, and the efficiency is still relatively high when the ambient temperature is low. It is safe, energy-saving and environmentally friendly, but it is relatively bulky, the glass tube is fragile, scale is easily accumulated in the tube, and it cannot work under pressure.
2. Flat Plate Solar Water Heaters
Flat plate solar water heaters can be divided into tube plate type, wing tube type, snake tube type. , flat box type and round tube type and heat pipe type. Suitable for use in southern regions where winter does not freeze. It has good integrity, long service life, few defects, can work under pressure, is safe and reliable, has a large heat absorption surface, but has poor thermal insulation performance.
3. Hollow Flat Plate Solar Water Heaterceramic
Ceramic solar panels are based on ordinary ceramic. It is a thin-walled hollow flat box solar collector with a three-dimensional array of black porcelain at the vanadium-titanium as a surface layer. Ceramic solar panels are made of porcelain material as a whole, which is waterproof, has high strength and good rigidity, does not corrode, does not age, does not fade, is not toxic, harmless and non-radioactive. The absorption rate will not fade and provides long-term high performance. High photothermal conversion efficiency and wide range of uses.
