For about 3 decades, manufacturers have been in a race to achieve devices that are more efficient, durable and sustainable. In this race, the Chinese consortium Sunman stands out, in the solar panel area, who has created a solar module that presents a series of physical characteristics, installation and photovoltaic properties. Let’s see what this is about!
The new glass-free solar panel that supports various forms of installation
Sunman, an innovative Chinese company, brings us a solar panel that, according to its report, can be installed with any method. As on roofs, fixed and removable, mechanical adhesive, with an aluminum base, removable, quick joining and even mobile.
In addition, it doesn’t have glass, which is an advantage, especially in regions where hail is frequent and of large diameter. Plus, with the optional stand base and installation hardware integrated and pre-assembled, you can save up to 40% on installation time and materials.
This solar module, called SMH520J-12X12UW, is a great advance in the area of solar energy and comes to give it a new boost now that it was lagging behind compared to other renewables.
How it is built and what are the characteristics of this photovoltaic panel
This revolutionary solar panel has a temperature coefficient of 0.34 / °C, has a white backsheet and a weight of 4.1 kg / m², or 11.1 kg per complete panel. It is monocrystalline technology, making it ideal to be mounted in areas where solar energy is deficient and comes in various powers up to 520 W. It is well known that this technology is characterized by being the most efficient of all.
Regarding the power it produces, it has an excellent power conversion efficiency of 19.2% at full solar irradiation. On the other hand, its open circuit voltage is variable, up to a maximum of 49.5 Vdc. Now, the short circuit current, for the 520 W panel, is an astonishing 13.56 Amps, on a day with strong sun.
It is made up of 144 half-cut monocrystalline solar cells, for greater durability and performance joined with micro metallurgy, so losses are minimal. On the other hand, it has an anodized aluminum frame with a special treatment, a junction box with IP68 classification and non-traditional moisture-proof connectors.
Likewise, this glassless solar panel can be used with high voltages in the solar energy system, since it supports up to 1500 Vdc. Additionally, it can operate under the most extreme climates, since its operating temperature is in a range between – 40 and 85 °C.
It is made in a manufacturing process that is based on the use of fiberglass reinforced plastic (GRP). Material that, according to the data provided by the manufacturer, gives many options for assembly, both in existing and new shapes.
Likewise, this material combined with the elimination of glass, minimizes light reflection that reduces performance in others.
Everything is very good but… What about the warranty?
According to the manufacturer, this solar panel has a 12-year product and construction materials warranty. Regarding linear power, its warranty is 25 years. Likewise, it guarantees that the power output at the end of 25 years, will be at least 84.8% of the rated power output when it began service.
As you can see, this solar panel offers impressive power and performance characteristics. And just like this, we will surely continue to witness other advances in renewable photovoltaics.
