Solar Panel Model 685 SP250 12V 2.5 Watt

Features: This solar panel is specially designed for sailing boats, cars, radios, tent-fans, portable televisions, flash lights, warning lights etc. It converts the sunlight into direct current (DC) electricity, then supplies power to a rechargeable battery which in turn, provides power to operate the appliance load, day time charging for night time use. The cells are laminated in E.V.A. resin with polycarbonate surface, and epoxy sealed with silicon rubber into an ultra violet inhibited polycarbonate plastic housing, so the solar panels have been designed to withstand the rigors of weather. HOW TO USE (3 options): 1. You can clip them onto a rechargeable battery that will eventually run an appliance without clipping it to anything else. 2. You can clip it directly to the appliance that you want to run, like a fan. 3. You can clip it to a rechargeable battery, and the appliance at the same time. UNIQUE FEATURES: Water-proof Rust-proof Easy installation Corrosive-resistant Built-in blocking diode Able to resist heavy weights Cable wire is provided for connections purposes. Kit stand is provided to adjust to face the sunlight. Weather-proof, protects against humidity, snow, ice, rain, wind SPECIFICATIONS: Voltage Voc : 12V - 16V max. Power : 2.88 Watts Current : 120mA - 140mA max Unit Dimensions : 6 x 11 x 1 inches

SOLAR RACER KIT (requires assembly) AK590




Solar Power

Build your own solar-powered models and discover how solar cells generate electricity from light. Build six solar powered models including a locomotive, single-prop plane, bulldozer, helicopter, backhoe, and twin-rotor helicopter.

The special solar panel in this kit consists of three solar cells and generates 1.5 volts of electricity in bright sunlight, like a AA battery. A unique cradle holds either the solar panel or the battery, allowing you to switch out the solar panel for a AA battery (not included), depending on the strength of sunlight. You can even use the solar panel to charge up your own rechargeable AA batteries. The solar panel is positionable, so you can maximize its exposure to the sun to generate the most power.

The 24-page color instruction book included in this kit gives step-by-step instructions for assembling the six model vehicles. After you have built the suggested models, you can design your own solar vehicles. Compete with your friends to see whose solar vehicle runs the fastest!
