Risen RSM120-6-315M Half-Cell Solar Panel

Description

If you’re looking to purchase the most efficient, high-tech Tier-1 solar panel, then you should definitely consider the Risen RSM120-6-315M monocrystalline solar panel. The panel features a high efficiency rating in watts per square meter and utilizes half-cell and PID-resistant technologies. 

The panel is manufactured by Riesen Solar—one of the world’s most renowned solar panel manufacturers. Year after year, this company ranks among the top Tier 1 manufacturers. This list ranks manufacturers characterized by an unquestionable reputation, a long history in the market, a fully automated production cycle—starting with crystal fabrication—and significant investments in scientific and technical research, the results of which are applied to their own products. All panels are certified according to European standards; in Photon’s field tests, they ranked second among 176 solar panel manufacturers.

The panel has a power output of 315 W, a monocrystalline cell type, an efficiency of 18.91 TP3T, and 5 current-collecting tracks (bb).

An important feature that complements the advantages of this panel is its industry-leading thermal power loss coefficient of -0.39%/°C. This is particularly relevant during the summer, when ambient temperatures are high and the panel heats up to 60–70°C. 

Half-Cell technology means that the panel is effectively divided into two parts, each containing 60 solar cells that are half the size (half-cells) and are less susceptible to mechanical damage. As a result, if half of the panel is shaded, the other half will continue to operate normally and generate electricity. The smaller distance between the solar cells reduces the current resistance by 5%.

PERC technology involves applying a special dielectric layer with small holes to the bottom aluminum wall, which allows for the additional reflection of sunlight passing through the panel and generates additional electricity. As a result, the solar light absorption coefficient increases to 20%, which leads to an overall increase in the photovoltaic module’s efficiency.

Resistance to potential-induced degradation (PID) ensures greater resistance to power loss over time. The panel is also resistant to salt, sand, and ammonia. It has an IP67 dust and moisture protection rating, which prevents air or water from entering the panel. The panel has been tested for wind (up to 2,400 Pa) and snow (up to 5,400 Pa) loads.

Despite its large number of solar cells (120), the panel has standard 60-cell dimensions of 1685x992x35 mm and weighs 19 kg. The panel comes with a 25-year warranty.
