  1. SHELL STO.4-XI SOLAR CELL, 60MM X 60MM X 2MM

    3.2 VOLTS DC 80MA CIS SOLAR CELLS - TEMPORARY SPECIAL!!!!

    These are thin-film Copper Indium Diselenide (CIS) solar cells. Recent production, first quality, made by a major solar manufacturer. 60mm x 60mm x 2mm thick (2.4" x 2.4" x .08") The active semiconductor material is deposited on the front of the glass, tinned ribbons are bonded to the edges, then the whole cell is covered with clear tough plastic to protect the cell and ribbon. They are environmentally protected and ready to use. You just solder to the ribbon and mount them in your project. The cells put out about 4.5VDC open circuit and about 100MA short circuit. Maximum power of the ones tested is about .25 watt (80MA at 3.2VDC). CIS is the most stable and rugged of the thin film solar technologies and is about twice as efficient as amorphous silicon. It is more efficient under cloudy or partial shade conditions than crystalline silicon. CIS is also radiation resistant, and therefore often used in spacecraft applications. You can connect them in series for more voltage and in parallel for more current. These should be good for walkway lights, battery charging, remote instrumentation or data loggers, educational projects and other DC electrical applications. Unlike amorphous silicon panels, CIS panels do not degrade due to sunlight exposure. In fact after at least 2 hours of exposure to sunlight of at least 1/2 standard intensity, the output will increase by about 10%. With the first exposure, the semiconductor material is annealed and the output is then stable at the higher level. (This is called light soaking). We have a very large quantity for immediate sale.

  2. FOLDING 6.5 WATT SOLAR CHARGER

    FOLDING 6.5 WATT SOLAR CHARGER

    Flexible, foldable 6.5 watt solar charger works great with automobiles, RV's, boats and small electronics. Made of nylon with high efficiency thin film solar cell. Max Output 6.5 watts 433 mA, built-in blocking diode protects battery discharge at night. Includes: 4 grommets, battery clamps, 12V female socket, CLA adapter & barrel plug connector and 8 ft. wire. Dimensions: 6.20" L x 3.20" W x 10" H, weight: 1.31 lbs.

  3. SOLAR-CELL WITH CHARGING CIRCUIT

    6V SOLAR PANEL COMPLETE WITH CHARGER

    These assemblies for sun-powered garden lights consist of two glass photovoltaic cells mounted on a plastic bracket with a charging circuit, two rechargeable AA cells, and one amber LED. Between the solar cells is a photoresistor to sense light and dark conditions. In daylight the solar cells charge the battery. When it gets dark, the LEDs light. These are working units but the batteries are old and may not take a charge. Solar cell surface area is 3.78" x 1.98". Cells provide 2.6 Vdc @ 25mA in bright sunlight.
