What are the requirements for the installation location of solar outdoor wall lights

Adequate lighting resources to ensure energy supply
Solar outdoor wall lights rely on photovoltaic modules to convert solar energy into electrical energy. The core factor that determines its performance is the sunshine time and intensity of the solar panel. The installation location must be unobstructed throughout the day, especially during the high-intensity sunshine period from 10 am to 3 pm, it should be as unobstructed or semi-obstructed as possible. Common sources of shading such as building shadows, eaves, tree branches and leaves, billboards, and air-conditioning units should be avoided. The ideal installation direction is due south or slightly southwest, and the inclination should be adjusted according to the local latitude and season so that the panels always maintain the best light receiving angle, thereby maximizing the photoelectric conversion efficiency and power storage capacity.

The installation structure is stable to avoid wall hazards
As a wall-mounted device, the fixed structure of the solar wall light directly depends on the installation base. The installation wall must have sufficient strength and stability. It is recommended to choose hard surface materials such as solid brick walls, cement walls, and stone walls that can firmly withstand the weight of the equipment body and the impact of wind. For non-load-bearing base surfaces such as exterior wall insulation, wooden structures, and gypsum board walls, extended expansion bolts, special hanging plates, or additional mounting parts must be used for reinforcement. Long-term exposure to wind and sun may cause loosening or even falling. When selecting a site, the wind resistance should be reasonably evaluated in combination with local annual wind speed data.

Avoid high humidity and high corrosion environments to extend service life
Some installation areas are humid and rainy all year round, or are close to coastal areas, industrial areas, and other environments with severe corrosive gases, which will accelerate the aging and corrosion of the lamp housing, circuit boards, and connecting wires. Try to avoid locations such as damp walls, poor drainage, and near drains. If it must be installed in rainy and foggy areas, stainless steel, aluminum alloy, or high-density plastic housing products with IP65 or higher protection levels should be selected, and ensure that the joints of the lamp body are well sealed. The installation point must not be directly connected to a platform prone to water accumulation to prevent water from backflowing into the lamp in heavy rainy weather.

Avoid strong interference sources to ensure system stability
Some models of solar wall lights integrate intelligent components such as microcontrollers, induction radars, and photosensitive probes, which are sensitive to external electromagnetic signals, heat sources, or light sources. The installation location should avoid potential interference sources such as large electrical equipment, strong power lines, and high-frequency communication equipment to avoid light control misjudgment, frequent flashing, or sensor function failure. At the same time, avoid installing the lamp in high-reflective areas such as glass curtain walls and metal reflective surfaces to prevent the reflected light from misleading the light control sensor and affecting the night lighting judgment.

Reserve appropriate height and angle to improve lighting effect
The main lighting function of solar wall lights is local area fill light or contour lighting. The installation height is usually recommended to be between 2 meters and 3.5 meters, depending on the specific application scenario. Too high may lead to insufficient illumination, and too low may cause glare or induction blind spots. It is recommended to install the induction wall lamp at a distance of 2.2 meters to 2.8 meters from the ground to obtain the best induction angle and coverage. The irradiation angle should avoid the direct view area of ​​the human eye, and it is recommended to install it at a downward tilt of 30 to 45 degrees, which will help achieve efficient beam projection and reduce light pollution.
