The installation angle of solar glass tubes should be within the optimal angle range for collecting solar energy. The optimal installation angle of solar glass tubes depends on local location and season. In the northern hemisphere, the installation angle of solar glass tubes is generally adjusted to the same angle as the geographic latitude, that is, inclined along the great arc of the earth, in order to maximize the reception of radiation solar. For the installation of solar water heaters, it is generally recommended that the installation angle of solar glass tubes be between 20 and 50 degrees. Of course, the recommended angle is not fixed. The actual installation angle should also be adjusted appropriately taking into account different geographical locations, climatic conditions, seasons and other factors. During the installation process, you should evaluate the specific local conditions and find the bestinstallation angle to ensure the best performance and thermal efficiency of the solar water heater, thus providing a more comfortable and environmentally friendly hot water supply.
How to determine the installation direction and angle of solar panels?
5 to 10 degrees west of south.
When installing solar racks, it is usually more suitable to install them on the roof or in a higher location. If the installed solar panels are for domestic use, they should generally face north and south, between 5 and 10 degrees west of south, to ensure no sunlight. Minimize the number of pipes entering the house and increase the amount of sunlight. When installing, you can first use a compass to find the true south position and mark it.
The design of the solar water heater support must have strength andsufficient rigidity to guarantee sufficient load-bearing capacity. In coastal areas, when purchasing a home solar water heater, you should also pay attention to whether the product is designed to withstand wind. Generally, the brackets of better quality solar water heaters are made of aluminum alloy brackets, which are thick and strong.
Detailed information:
Notes:
1. Solar water heaters are installed outdoors, so the water heater and roof must be installed securely to withstand strong winds. .
2. During the northern winter, water heater pipes must be insulated and frost-proof to prevent water pipes from freezing and cracking.
3. The water heater must be designed and installed by the manufacturer or a professional installation team.
4. Check once a year ifthe water tank is leaking, if the parts are aging, if the collector is damaged, if the support is rusty, etc. If problems are found, they should be replaced. and repaired on time. It is best to have them installed and maintained by a professional.

What are the placement skills of solar water heaters
Direction and l angle of installation of solar energy panels. Consider taking full advantage of solar energy. According to physics, the longer the sun shines on a solar panel and the closer it is to vertical exposure, the more energy it receives.
The direction and tilt angle can be divided into two parts:
Direction:
I want to get as much sunlight as possible throughout the day. According to the principle, the orientation of the solar panelsis:
The best direction is to face north in the southern hemisphere and south in the northern hemisphere.
Tilt angle:
The tilt angle of the panel is for allow solar power to receive as much energy as possible, and the size of the tilt angle is related to your latitude. Next, let's take a closer look. Because the Earth's axis of rotation and orbit are not perpendicular. From our point of view, the angle of the sun is different in different seasons, with a difference of 23.4 degrees. The midpoint angle of the sun occurs at the spring and autumn equinoxes. At noon that day, the angle of the sun is exactly (90 degrees – your latitude). Through comprehensive calculations, the optimal tilt angle for a year should be a little larger than your latitude to achieve the maximum value received throughout the year.
For example, 25 31 in Guangdong, the angle of all solar panels recommended for installation in Guangdong is about 30-35 degrees.
Installation area:
Average: 1 kW solar panel requires approximately 10 square meters Installation area.
1. If it is in the east-west direction, place the solar toward the west. The placement angle to the north is greater. are also different. First you need to check what type of house you have.
2. Avoid trees and slopes that block sunlight and choose the best placement location. Depending on local lighting characteristics and house layout. An angle of 60 degrees towards the southeast is then more appropriate, taking into account safety factors. This is determined based on site conditions. It has a flat roof and no obstacles around, facing south, and the included angle can bebetween 30 degrees and 90 degrees. Assuming the most ideal conditions, avoid tall buildings that block sunlight and face southeast.
3. First of all, consider that the installation is safe, solid and reliable, and that the location should be such that it can receive as much sunlight as possible throughout the day.
4. The heat collecting tube should face south, then 5 to 10 degrees to the west, which is most suitable, because sunlight in this direction is the strongest and the effect is the best.
