Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of photovoltaic water tanks, it is recommended to prioritize confirming the weather resistance and load-bearing parameters of the tank material. For example, the thickness of aluminum alloy should be adapted to local wind and snow load standards to avoid environmental factors affecting the drainage efficiency of photovoltaic modules.
  • In different scenarios such as agricultural photovoltaics or commercial rooftops, there are differences in the installation method and span design of photovoltaic water tanks. When purchasing, suppliers should be required to provide engineering case data for corresponding scenarios as a reference.
  • When selecting suppliers, priority should be given to indicators such as product compatibility, business qualifications, enterprise activity, industry performance, and industry data support to ensure that their supply capacity matches the project cycle requirements.
  • The technical parameters of the anti-corrosion coating for photovoltaic water tanks need to be clarified, and models that have undergone special surface treatment should be selected in coastal or high salt alkali areas to extend the service life of the overall photovoltaic support system.
