Longi LR4-72HPH-430M Solar Panel

Description

Longi – is one of the world’s leading companies in the development of solar photovoltaic modules. The quality of its products is confirmed by numerous international certifications (TÜV SÜD, CE, CSA), and the products themselves are known for their reliability and performance. The company sells its products worldwide, as evidenced by its inclusion in the ranking of the largest Tier 1 photovoltaic module manufacturers. The company is constantly improving its products, and as a result, it offers the modern and highly efficient Longi LR4-72HPH-430M solar module. This module boasts one of the highest power ratings on the market—430. In addition, models are available with power ratings of 425, 435, 440, 445, 450, and 455 watts. Combined with its high efficiency rating, this panel is one of the best on the market. 

The Longi LR4-72HPH-430M photovoltaic module features Half Cell technology. It contains a total of 144 photovoltaic cells. Its high power output is therefore due to the large number of photovoltaic cells. The solar panel is made of monocrystalline silicon, which demonstrates better efficiency during operation than, for example, polycrystalline silicon. The efficiency rating is 19.8 %.

The photovoltaic module has a power rating of 430 W. At the solar panel’s maximum operating power, the voltage and current are 40.7 V and 10.57 A, respectively. The open-circuit voltage is 48.5 V. The short-circuit current is 11.31 A. The device features optimal operating temperature coefficients. The temperature coefficient of power is -0.35 %/Co, which is better than the industry standard. The temperature coefficients for voltage and current are -0.27 %/Co and 0.048 %/Co, respectively. This coefficient determines the percentage loss of each characteristic (voltage, current, and power) when the temperature rises by 1 degree from the nominal value (45 Co). 

The photovoltaic module frame is made of anodized aluminum, so it is corrosion-resistant. The photovoltaic module is 3.5 cm thick. A 3.2 mm-thick tempered glass panel covers the front of the module and protects it from mechanical damage. The solar panel can withstand mechanical loads such as snow (5,200 Pa) and wind (2,400 Pa).
