[Easy to install] [Efficient solar module function] This well-constructed stand raises photovoltaic modules to the optimal height, allows proper airflow between modules and the surface, and ensures that modules remain cool at high temperatures. [Protection of solar panels] Non-corrosive, high-quality ABS photovoltaic module mounts for caravans protect photovoltaic panels from damage from side and corner mounting angles. Cable gland housing is IP68 waterproof, widely used in solar projects during the wiring process, with two rubber rings, the cable and fixed head will not be loose again. [Various applications for solar panel installation] Our solar panel motors are suitable for all solar panels with aluminum frame with a side length of cm or more, very suitable for large solar panels of 100 and above, no drilling required and firmly installed on the flat surface, widely used in motorhomes, large caravans, ATS sides, roofs and more.
