How to choose the installation wall for solar outdoor wall lights

Structural stability is the primary consideration
Although the solar wall light is small in size, it contains internal components such as solar panels, batteries, and circuit modules. In addition, it needs to withstand outdoor physical stresses such as wind and vibration, which puts forward requirements for the structural bearing capacity of the wall. It is recommended to use solid walls with good structural strength such as concrete walls, solid brick walls, and granite walls as the installation base. This type of wall can stably bear the weight of the lamp, and there will be no risks of loosening, falling, and deformation after long-term use. During installation, the use of expansion bolts, metal hangers and other fixing methods can achieve a long-lasting and reliable installation effect.

Surface material determines the construction method and firmness
Different wall materials correspond to different fixing methods and installation difficulties. Solid cement walls can be directly drilled with an impact drill and fixed with expansion screws, which is fast and reliable. Solid red brick walls need to avoid mortar joints during the fixing process to prevent loosening. For decorative walls with marble or tile veneers, special glass drill bits need to be used to drill holes carefully to avoid cracking the surface. Metal curtain walls or light steel keel walls need to evaluate the load-bearing capacity in combination with the backboard structure, and use metal self-tapping screws or reinforced fasteners to prevent falling off. For wooden walls, screws that are not easy to corrode and expand should be selected, and sealing rubber rings should be installed to enhance the waterproof effect.

Wall thickness must meet mechanical fixing conditions
Some lightweight walls such as gypsum boards, composite insulation boards, foam sandwich panels, etc. have limited thickness and many internal cavities, and are not suitable for directly bearing heavier lamps. If such walls must be used, local structural reinforcement should be carried out in advance, such as adding embedded reinforcement plates, transfer back frames, and external metal support parts to ensure that the installation point has sufficient pull-out resistance. If the wall thickness and structural support are ignored, there will be a risk of falling from a high altitude, which will pose a serious hidden danger to personnel safety.

Waterproof ability needs to match the level of lamps
Outdoor lighting equipment is exposed to wind and rain for a long time, and the waterproof performance of the wall directly affects the sealing effect and service life of the lamps. The walls around the installation location should have good anti-seepage performance, and there should be no water seepage, cracks, mold, etc. If installed on a tile or paint-finished wall, structural glue or waterproof sealing rings must be used to fill the holes after drilling to prevent rainwater from penetrating into the wall along the screws or wire channels, causing hidden leakage or corrosion. For curtain wall systems, attention should be paid to the joint treatment between the back of the lamp body and the wall to avoid the formation of dead corners of water accumulation.

Wall environmental adaptability affects weather resistance performance
Different climate zones have different adaptability requirements for installation walls. In cold areas, the wall should be frost-resistant to avoid structural loosening or surface shedding caused by thermal expansion and contraction; in high temperature and high humidity areas, the wall must be heat-resistant, moisture-resistant, and alkali-resistant to prevent the exterior wall decoration layer from peeling and bubbling; at the seaside or in a highly corrosive environment, anti-corrosion brick walls or structural walls coated with salt-resistant spray coatings should be used first, and installation accessories with anti-oxidation treatment should be used to enhance the overall weather resistance and extend the service life.

The flatness of the wall affects the installation level and visual effect
Solar wall lights usually have directional illumination functions. If the wall is obviously uneven, it will cause the installation angle of the lamp to deviate, the lighting area to be unbalanced or blocked. High-quality lighting design requires that the lamps are precisely aligned in the vertical and horizontal axis directions. Before installation, a level ruler or laser instrument should be used to assist in calibration. If necessary, local repairs should be made to the uneven wall or a base leveling structure should be added to improve the overall visual coordination and uniformity of lighting coverage.
