Selection of solar accessories requires consideration of multiple aspects, including materials, performance, brand and after-sales service. The following is a detailed selection guide:
Material and performance:
Photovoltaic modules: Photovoltaic modules are the core of the solar energy system. Choosing high-efficiency photovoltaic modules can improve the power generation capacity of the entire system. The photoelectric conversion efficiency of monocrystalline silicon photovoltaic modules is 18%-24%, which is the most efficient solar cell at present, but the cost is higher; polycrystalline silicon photovoltaic modules are slightly less efficient, but the cost is lower. It is recommended to choose original A-grade solar photovoltaic modules from well-known brands to ensure stable power generation and power generation.
Packaging materials: Encapsulants such as EVA (ethyl vinyl acetate) are used to provide adhesion between the top and rear surfaces of solar cells and photovoltaic modules, and need to remain stable and optically transparent under high temperature and high UV exposure.
Other accessories: Such as brackets, connecting pipes, etc., need to have good weather resistance and corrosion resistance to ensure stable operation under various climatic conditions.
Brand and after-sales service:
Brand selection: Give priority to solar accessories from well-known brands, such as first-line brands such as LONGi, Trina, and Jinko. These brands have mature technologies, and the power generation and stability of power generation are guaranteed.
After-sales service: Choose suppliers that provide high-quality after-sales service and technical support so that problems can be solved in a timely manner when they arise. High-quality after-sales service can ensure the long-term stable operation of the system.
Price and cost-effectiveness:
Cost-effectiveness considerations: From the perspective of cost-effectiveness, photovoltaic modules of 580Wp and above are generally selected. If the budget is limited, photovoltaic modules of 570Wp and below can be selected, but it should be noted that their performance may be slightly inferior.
Price comparison: Under the premise of ensuring quality and performance, compare the prices of different suppliers, but do not ignore other important factors just because the price is low.
