Description
The Chinese company Risen Energy is one of the best-known manufacturers of solar panels. The company is regularly included in the Tier 1 list—a ranking of leading solar photovoltaic module manufacturers that operate their own production lines and manage the entire solar panel manufacturing cycle.
The RSM120-6-285P Half-cell model offers an excellent combination of performance and value.
The device's technical specifications are as follows: the photovoltaic module's power output is 285 W, the open-circuit voltage is 38.75 V, and the short-circuit current is 9.4 A. The maximum current and voltage ratings for this model are 8.8 A and 32.4 V, respectively. The device is characterized by a low temperature coefficient of maximum power of minus 0.39 %/℃. The device’s efficiency is 17.1 %.
The solar cells are based on polycrystalline silicon. The half-cell technology incorporated into the design of this solar module allows it to operate more efficiently under partial shading, as the number of potentially active solar cells doubles to 120. Each solar cell has 5 current-collecting tracks or buses (5bb).
The device weighs 19 kg and measures 1685 x 992 x 35 mm. The panel housing is made of anodized aluminum. As a result, the photovoltaic module is protected against corrosion and is resistant to mechanical damage and deformation. The 3-millimeter-thick tempered glass can withstand wind loads (2,400 Pa), snow loads (5,200 Pa), and mechanical pressure.
The IP67 protection rating ensures that the device operates correctly and efficiently even when exposed to dust or moisture.
The photomodule has undergone preliminary testing, and we can confidently say that it is high-quality and reliable in operation.
