It is 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 solar panels installed 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 sufficient strength and rigidity to ensure sufficient 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 supports of solar water heaters of better qualityuality are made of aluminum alloy brackets, 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 if the water tank is leaking, if the parts are aging, if the collector is damaged, if the bracket 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.

Installation angle of solar water heater
Direction: southern hemisphere faces north, Hemisphere NorthSouth is the best direction. Angle: 9 degrees - latitude.
The tilt angle of the panel is intended to allow the solar energy to receive as much energy as possible, and the size of the tilt angle is related to your latitude. Because the Earth's axis of rotation and orbit are not perpendicular. The angle of the sun is different in different seasons, with a difference of ±23 or 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 = 9 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.
The installation angle of the solar water heaterre mainly refers to the installation angle of the sensor. The best orientation of the sensor is south. If conditions do not permit it, it can be modified within the limit of 10° east or west due south. When choosing the installation tilt angle, if used all year round, the tilt angle can be equal to the local latitude; if used in summer, the angle d 'tilt is local latitude minus 10° if used in winter; , the local latitude angle plus 10° can be taken into account. The tilt angle of solar water heater installation Requirements are not static.
