Product Advantages
JA Solar 640W modules are an excellent choice for those looking to improve the performance and efficiency of their solar energy systems. Here are five advantages of JA Solar 640W modules:
1. Better Low Irradiance Response: JA Solar 640W modules have a significantly better low irradiance response than traditional modules. This means that they can generate more power even in cloudy or overcast conditions, making them an ideal option for regions with less sunshine.
2. Better Temperature Coefficient: With a better temperature coefficient, JA Solar 640W modules are less affected by changes in temperature. This results in more consistent and predictable performance throughout the year, regardless of the ambient temperature.
3. 0.4% Annual Degradation Over 30 Years: JA Solar 640W modules have a very low annual degradation rate of only 0.4%. This means that they will continue to generate power at high levels for many years, ensuring a long-term return on investment.
4. 16bb Half-cell Technology: JA Solar 640W modules utilize 16BB half-cell technology, which provides even greater efficiency and power output. The increased number of cells also reduces the impact of shading, ensuring maximum power generation from each module.
5. Higher Power Output: With a high power output of 640W, JA Solar modules offer superior performance compared to traditional modules. This means that fewer modules are needed to generate the same amount of power, resulting in reduced installation time and costs.
