• EDUCATION---- Solar panels are devices that absorb sunlight and convert solar radiation directly or indirectly into electricity through photoelectric or photochemical effects, it's perfect devices for science project. It can be used for teaching purpose. Many of our customers comes from school,colleague,etc.

<b>Ideal for small projects: </b><br> Such as emergency lights, advertisement lamps, traffic lights, household lights, electric fans, solar water pumps, solar street lamps, etc. <br><br> <b>Features: </b><br> Material: polysilicon <br> Max. power: 3W<br> Max. voltage: 12V<br> Max. current: 250mA<br> Size: 145*145*2.5mm/5.7*5.7*0.1in<br> Weight: 80g/0.18Ib<br><br> <b>Package Content: </b><br> 1*solar panel<br><br> <b>Configuration Relationships between solar panel and storage battery</b> <br>       Storage Battery             Solar Panel <br>             1.2V                     &nbsp2V ~ 2.5V <br>             2.4V                     &nbsp3.5V ~ 4V <br>             3.6V                     &nbsp5V ~ 6V <br>               6V                       7.5V ~ 9V <br>             12V                      &nbsp15V ~ 18V <br> <br>When the voltage of your solar panel doesn't satisfy your storage battery, you can take two or more same solar panels together in series. Such as, two 5.5v solar panel connect together in series, so its voltage is 11V.<br> When the voltage of solar panel satisfies your storage battery. In order to speed up the rate of charge, you can take two or more same solar panel together parallel connection.
