DIY Polysilicon Solar Epoxy Cell Charger for Sunnytech 3.5w 6v USB Mini Solar Panel Module

Sunnytech, a family-owned business, started in a garage in New Jersey with a commitment to producing and selling only products that the company would be proud to use in their own homes and yards. Sunnytech follows a "triple bottom line" concept, which aims to achieve a successful and sustainable business model by considering the impact on people, the planet, and profit.

The company believes in doing the right thing, doing it well, and supporting people, the planet, and profit. Sunnytech's 100% zero landfill policy reflects their dedication to environmental stewardship, as all leftover materials, including electronic products, are recycled.

Designed for easy use at home, school, lab, or workshop, this 2W solar panel is perfect for a variety of solar projects. The compact size and high conversion rate make it suitable for creating solar walkways, lamp repairs, solar LED displays, or powering motors in self-powered models and portable toys. The panel can also be used to build a portable charger for small DC batteries, ideal for camping, hunting, or travel.

The solar panel features color-coded wires with alligator clips, making it easy and fun to work with. For those who want to connect multiple panels, the panel has two soldered tabs for permanent connections. The high-quality epoxy resin and unique technology ensure the components are beautiful and strong, resistant to wind and snow, and increase the panel's service life.

While the solar panel can charge power banks, MP3 players, and other digital products using the USB 2.0 interface, it is not suitable for charging smartphones like iPhones or Galaxies. This is because smartphones have a current protection system that prevents them from being charged by the solar panel's unstable current due to changing sunlight conditions. Any advertisement claiming the ability to charge iPhones is a false claim.

The solar panel is an excellent educational tool, as it demonstrates the photoelectric or photochemical effects that allow solar radiation to be directly or indirectly converted into electricity. This makes it a perfect device for science projects.

To optimize the solar panel's performance, users can connect multiple panels in series or parallel. When the voltage of the solar panel doesn't satisfy the storage battery, connecting two or more panels in series can increase the voltage. Conversely, to speed up the charging rate, connecting multiple panels in parallel can be beneficial.

The solar panel is suitable for a wide range of small power applications, such as emergency lights, advertisement lamps, traffic lights, household lights, electric fans, solar water pumps, and solar street lamps.

In summary, Sunnytech's solar panel is a versatile, high-quality, and easy-to-use product that supports the company's commitment to sustainability, education, and small-scale renewable energy solutions.
