It is a tempered and patterned glass, too, for maximum durability that enhances the long life span of the unit.
But there was an issue with the performance rating that other customers encountered with this product. For instance, they claim that the performance is less than what the manufacturer stated since the rating was only at 75 to 80 percent during a high-sun condition. Although the cost per wattage is more reasonable, as compared with other 100-watt solar panels on Amazon, the actual power output is less than the rating. This has an impact on the overall customer satisfaction since some people expected more from this item. Nevertheless, the shipping process was fast and there were no damages to the unit upon arrival.
1.Suaoki 12 V 100 Watts Solar Panel Battery Charger Ultra Thin SunPower Cells
The Suaoki solar panels make use of the SunPower cells that provide an efficiency rating that is 23 to 25 percent more than the average ones on the market. There is a unique internal blocking diode component incorporated to the panel to prevent the reverse current drain issue during night time. The solar panel is highly durable and water-resistant, so it can be used on boats, RVs, and other areas that are otherwise not suitable for aluminum and traditional glass solar panel models. Since the panels have a bendable or flexible design, it is easy to flex the unit to make sure it follows the smooth and precise curve of the area where you will place the panels.
The durable and well-made panels are lightweight, yet undeniably powerful at the same time. They can pack up to 100 watts of maximum power in the 0.1-inch thick panel, but the overall weight is only at 4.85 pounds. Thus, you should never find it an issue to transport, mount, and remove the panel. With the frameless design of the unit, installation is made simpler. There are also four pieces of metal-reinforced holes for mounting located at each corner. These all add to the quick installation and in fixing the screws.
Great for hiking, camping, outdoor travels, and even home use, the Suaoki solar panel is flexible, lightweight, and contoured to make installation effortless. But there are some things you might want to know about this product to make sure you get the maximum benefits from it. One, be sure to avoid connecting the panels in a parallel position since it can cause an overcurrent that will lead to damages to the battery and the unit. If you do a series connection, it is not advisable to use over 4 panels. If the voltage goes beyond 40, you will have to use an additional controller to prevent overcharging the device. Most importantly, always handle the panel with optimum care and protect it from bumps and over-bending. Otherwise, damages to the unit may occur, which can negatively impact its performance.
However, if you are using a larger solar panel or even multiple panels that need to be installed, ground or roof mounts should be ideal for this situation. There is a tilting type of mechanism in these mounts, which can help increase the life span and efficiency of the solar panels. But if space is an issue, pole mounts are perfect. These secure the panel to a high pole by utilizing a bolt system. Just steer clear of pole mounts if you are in a place where it is often windy.
In the long run, solar panels can result in higher savings, although the initial investment may be a bit overwhelming for some. You can eventually get rid of your energy costs at home while selling unused energy to companies for even greater profits in the future.
