When purchasing photovoltaic modules, we suggests that you should not only take your income status into consideration, but also the component cost and overall operation and maintenance cost. Photovoltaic module testing can help you determine which type of battery module offers good performance and low cost. Currently, the battery modules available on the market include polycrystalline modules, thin - film modules, and monocrystalline modules.
The shapes of monocrystalline and polycrystalline modules also vary in appearance. Polycrystalline battery cells are square substrates. Polycrystalline silicon can be directly processed into square materials through special methods. The silicon rods of monocrystalline battery cells are cylindrical, and when they are sliced into solar modules, the planar utilization rate is relatively low. Polycrystalline battery modules are blue, which leads to a reduction in the conversion efficiency of solar light. Engineer Zhang from Noah Testing indicates that monocrystalline battery modules have significant advantages in this aspect. They are black and have a higher photoelectric conversion efficiency compared with polycrystalline battery modules.
In terms of price, the cost of monocrystalline battery modules is higher than that of polycrystalline modules, but they have a relatively higher conversion rate. At present, most photovoltaic projects on the market prefer to purchase polycrystalline battery modules. This is because the production process of polycrystalline battery modules is simpler than that of monocrystalline modules, and the cost is lower. Among the battery modules, there is also a type called thin - film modules. They have strong light - transmittance and are suitable for agricultural greenhouses that require high light - transmittance and buildings with insufficient load - bearing capacity. However, the disadvantages of thin - film modules are their high cost, large land occupation, and long payback period. Therefore, currently, polycrystalline battery modules are the first choice for developers, resulting in a relatively high market share of polycrystalline battery modules.
In conclusion, there are many reasons for the popularity of polycrystalline battery modules, ranging from price to ease of use. They have mature technology, a high cost - performance ratio, a short payback period, and are suitable for most photovoltaic operators.
