1. The optimal placement angle of solar photovoltaic panels is 45 degrees.

2. When installing solar panels, the first thing to consider is the choice of direction. If you choose the wrong direction, the angle is useless. If the direction is wrong, it will not receive sunlight at all. Now common solar devices, such as solar street lights, have been carefully observed and found to be in the south direction, which has been scientifically studied. When the direction of the solar panel is due south, the power generation efficiency is very high. When choosing the direction, also pay attention to the influence of surrounding buildings and trees.

3. When installing, control it in the south direction and do not deviate too much. The more efficient situation is within 20 degrees of the southwest direction, so that there can be good sunlight supply and power generation in winter and summer. If it cannot be placed in the due south direction or some solar panels cannot be placed, it can also be placed in the east-west direction, and it can also generate electricity for half a day. Don't miss the sun in the north for a day.

4. After choosing the direction, the next step is to choose the angle of inclination. Different angles have different light hours in a year. If it is placed flat and the sun is not direct, the effect is not much different in one day, but a long time accumulation can reach a big difference. For the inclination angle, most of the solar panel angles are around 45 degrees, which is determined by the local latitude, because the angle of sunlight is different at different latitudes, it is recommended to be around 30 degrees in the south. However, if more detail is required, the computer can accurately calculate a value based on the local latitude, so that the power generation efficiency can reach the desired goal.

How to install solar panels?

How to install solar panels to maximize their use value? The installation method of the solar panel is as follows:

1. First distinguish the positive and negative electrodes. When making a series electrical connection, the "+" pole plug of the previous component is connected to the "-" pole plug of the next component, and the output circuit should be correctly connected to the equipment. If the polarity is wrong, it may not be able to charge, and even in serious cases, the diode will be burned and its service life will be affected.

2. Choose to use insulated copper wire, both in terms of conductivity and resistance to galvanic corrosion, it is very good, and the safety factor is also higher. When conducting the insulation winding of the joint part, first consider the insulation strength and weather resistance, and leave a margin for the temperature parameters of the wire according to the installation ambient temperature at that time.

3. Choose the appropriate installation direction and fully consider whether the light is sufficient.

4. In order to effectively ensure the working efficiency of solar panels for a long time, regular maintenance should be carried out after installation.
