Solar Panel works well even in low light, guess it's because of the 'mono PERC' technology Bought it just for learning purposes 1. Bluebird Solar 100 Watt 2. AmiciSmart Solar Charge Controller 10A 3. 7AH Exide (UPS Battery) 4. SuRCLe Solar MC4 Connectors ( only wished that BlueBird would had provided two extra MC4 Connectors along with the panel as its difficult to find in local market).
