Product Description
Ramsond solar panels use the most premium components and raw material. Ramsond solar panels use only 'Grade A' quality, high purity silicone cells. Ramsond does not incorporate used, rejected, refused or second-hand cells into its solar panels. Furthermore, Ramsond utilizes the most advanced technologies in the production of its panels, such as a fully automated, microprocessor guided, precision, robotic arms guided soldering process of the solar cells. The solar cells are coated with a blue nitride anti-reflection coating. This special coating process provides a uniform blue hue color and increases light absorption in all weather conditions. The encapsulation and lamination process used with Ramsond solar cells consists of a process that ensures true atmospheric vacuum and encapsulation of cells within lamination layers of High Ethylene Vinyl Acetate (High-EVA) and DuPontTM Tedlar®. Each panel is equipped with low-iron, patterned, tempered glass. The glass has been manufactured, again, through a proprietary process, providing up to 60% more strength, as compared to conventional photovoltaic (PV) glass. As a result, Ramsond panels are among the world's strongest, with hail impact survival index rating of 25mm@80 km/h. This means the specialized PV glass of Ramsond panels can withstand hail size of 1+ inch, traveling at speeds of approximately 50 miles per hour. Ramsond solar panels are framed in heavy duty anodized extruded aluminum with drainage/mounting holes. The aluminum frame is specially produced for Ramsond solar panels and is designed to provide a perfect balance of technology, style and function. The combination of the advanced components and production techniques, along with Ramsond's industry leading 25 Year Limited Power Warranty, make the Ramsond series of solar panels, among the most advanced and sought after PV modules in the world.

Great product does exactly what I need It to do. I use this and a sunshield to keep my tractor battery charged during the cold months so I do not have to jump it or charge it prior to the times I need to use it.

This is a nice panel that upon voltmeter assessment in full sun, actually slightly exceeded the amperage rating by the manufacturer. The open circuit voltage (Voc) is also at the rated voltage. The build quality appears to be good with the exception of the sealing of the panel on the back side. The original panel I ordered actually was not sealed in the back at all. I sent it back for a replacement, which they did with a free return shipping label as it was defective. However, the replacement panel also had a poor quality silicon sealant job done on the 4 sides on the back of the panel where the white tedlar backing joined the aluminum frames. I just caulked it myself as I didn't want water intrusion over time. I was also tired of returning a panel that only cost me 65 bucks including shipping.Overall a good buy for the money. They could do better with the quality control. I anticipate it will hold up well overall, however and it has a 25 year output warranty.
