Good Conversion Efficiency

The manufacturer stated that the customers receive good conversion efficiency from this unit. The Topsolar bendable solar panel has highly efficient Mono-crystalline solar cells. These solar cells have special back-contact technology to remove electrodes from the surfaces. Therefore, these solar cells are capable to remove the blockage of sunshine and it produces high energy. According to the manufacturer, the conversion efficiency is up to 50% more than others on the market.

Superior Quality Materials

It is made of ETFE material. You should know that ETFE material is responsible for higher light transmittance and long-lasting performance. Such capabilities may not be available in ordinary materials. In the solar panel sector, ETFE material is used to make these products because it is helpful for the best performance. The backplane adopts TPT to dissipate heat. Moreover, it is waterproof and temperature-resistant material. It is also easy to clean.

Many Applications – you can use it for charging a 12V battery. In case, you need to charge a 24V battery or 48V battery, you can connect multiple solar panels in series to charge batteries such as 24V, 36V and 48V. In case, you need to charge a battery, you will need a controller. A controller is very useful to protect the connected battery. You will not get any difficulties to connect the solar panel with the controller or regulator.
