Portable outdoor power supply, cell phones, small power appliances can be charged. If charging RV battery, please add SHAWLLAR special controller.

Use a soft brush and damp cloth to clean the dust on the surface of SHAWLLAR Portable PV Bag. Bird droppings or other sticky objects should be cleaned with a damp cloth immediately. If you need to clean the solar panel, please use running water to wash the surface, avoid using high pressure water gun to rinse, too high pressure will damage the SHAWLLAR portable photovoltaic bag denim.

The SHAWLLAR Portable Photovoltaic Bag is waterproof to IP65 and splash-proof (not to be placed in the rain or submerged in water). To protect the use of the product, please keep the product dry.

Solar panel power generation power is affected by a variety of factors. The main factors include climatic conditions, light angle and shading. Climatic conditions: general cloudy weather, or cloudy weather, the sun is blocked by the cloud conditions, will lead to a decrease in power. shading: shading in front of the solar panel or placed behind a glass window can lead to a decrease in power. Angle: when the solar panel is not facing the sun vertically, or with its back to the sun can lead to a decrease in power. Warning: Please avoid letting external forces squeeze the solar panel, otherwise it may damage the solar panel silicon wafer and lead to power drop.

It is not recommended that you use SHAWLLAR portable photovoltaic bag model in extreme weather conditions, please try to use it under stable weather conditions. Avoid using it in bad weather conditions such as thunderstorms, high winds, hail, etc. Normal use temperature is -4℉ to 170℉ (-20℃ to 70℃).

The PV package currently on the market only converts solar energy into electrical energy and transmits it in the form of direct current to mobile energy storage power products. Solar panels themselves can not store electrical energy. If you want to store electricity, we recommend that you use SHAWLLAR portable power supply .

Compared to hard panels our cells with a white edge will indeed be lower than the nominal value of hard panels, but under the same circumstances test results our power generation is about the same as hard panels, and even higher in some cases than hard panels.

At the moment we are selling from 2 pieces, if you are not buying in multiples of 2, please contact us. We will change it for you.

There is no question of who is more or less efficient with flexible and rigid panels, it is important to see if it is a qualified mainstream plant, now it is in the link of production line change, technical improvement is in the wind, who has more advanced production line, has more efficient products. Shawllar Technology's Zero Carbon Engine solar flexible module can reach 100W in an area of 0.52*1.065m, which exceeds most hard panel modules, and its also includes the location of junction boxes.

The first flexible modules are thin film modules, and it is only in recent years that crystalline silicon cells have been used to make flexible modules. However, the technical requirements are high, the process is complicated, and the market application is small, so there are almost no big factories to do it. Some of the existing flexible modules After seeing the rise of the RV market, the manufacturers use the older manual production line to make flexible modules, which cannot meet the photovoltaic certification requirements, hastily put into the market, only seeking quick profits, with no quality assurance at all. The substrate used The material used is just ordinary polyethylene (plastic), so it is very easy to yellow and even peel after sunlight exposure. And Shawllar uses KPK (double-sided fluorine) liner which is used only in high temperature difference environment, which is higher than hard plate KPF (single-sided fluorine) liner. The POE fluorine film material used on the front side has the characteristics of high light transmission, high weather resistance, high surface strength and easy to clean, and is the material of choice for the front side of flexible components. Genuine flexible components will not peel and yellow!

It is best to use modules with the same voltage and internal resistance for series and parallel connection. The reasons are as follows. Solar PV panel power generation is a system problem, so there is a short board effect. Each module internal cells are in series mode, each silicon cell voltage is about 0.5V or so, so can calculate the module working voltage for the number of cells multiplied by about 0.5V, the smaller the area of the module contains fewer cells, and thus the smaller the module working voltage. Zero Carbon Engine 100W module consists of 36 cells connected in series, so the working voltage of Zero Carbon Engine module is about 20V. Each module has an optimal voltage for power generation, and the best power generation is achieved when the overall system voltage is maintained at the optimal voltage of 20V. When two modules with different voltage and internal resistance are connected in parallel, the working voltage of the system will be closer to the panel, and the high voltage module will lose most of its power generation efficiency under the low voltage, while the high voltage module will reverse charge the low voltage and low internal resistance module, which will eventually result in the output power being less than the sum of the two, and the larger the voltage difference, the less the output power will be than the sum of the power of the two modules. Adding an extra small board not only does not increase the expected power generation efficiency but also reduces the original power generation capacity.
