SoloPower SP4-100 100W CIGS Peak Power Rigid Glass Solar Panel
This is a rare CIGS glass solar panel made by Solopower. Solopower typically made thin flexible panels. The voltage on this panel will work for a 12 volt battery charger but you will need to make sure your charge controller can take an open circuit voltage of at least 32 volts. Typical voltages for 12 volt battery chargers range from 15 to 18 volts. This panel at 21 volts will work but its on the high side. Operating Voltage: 21.4V Operating Current: 4.7A Open Circuit Voltage: 32V Short Circuit Amps: 5.8A Overall Panel Dimensions: 58.5L x 32W x 1.5D Glass Coverage Dimensions: 57L x 30.75W Panel Weight: 32 lbs. This panel will require freight shipping or local pickup. Its possible to ship it but it would take about $50 in materials and 2 hours labor to build a custom box that would withstand UPS or Fedex handling.
