2001 Solar Cell Analysis Data - Direct S...

| Overview | ||
| At Solarbotics, we've been getting quite a few questions regarding the "real-world" performance of our solarcells. Although we do have the official Panasonic Sunceram datasheets, it is written in a quite technical manner and does not include practical design data. With that in mind, we have generated the following - the first of three sets of data for use by the BEAM community. This first set of data is taken with direct-sunlight performance in mind. The second and third sets will be measured under halogen and incandescent lighting (stay tuned...). | ||
| Data Acquisition Procedure | ||
| Solarcell voltage across resistance values recorded on June 20 between 13:07 and 13:25. Solarcell capacitor charging values for capacitors between 1000uF and 4700uF recorded on June 22 Between 13:30 and 14:00.Solarcell capacitor charging values for capacitors between .047F and 1.0F recorded on June 25 between 13:25 and 14:10.Summer solstice on June 21, maximum sunlight at 13:37 (located in Calgary, Alberta, Canada).Testing apparatus consists of a basic stamp 2 for data logging and a ADC0831 chip for analog to digital conversion, 8 bit accuracy (0.02 volt resolution). When testing multiple resistive loads, relays were used to switch the load across the solarcell with a 200ms settle time. The basic stamp controlled sequencing and data logging by measuring the voltage across each switched load.When testing the charge rate of multiple capacitors, the capacitor was shorted by a relay for a period of five seconds, then released to charge by the solarcell. Voltage readings were taken between .2 and 5 seconds, depending on estimated total charge time. An 80% open voltage line is also indicated on the graphs. |

SparkFun hates robots.
We love SparkFun. Great group of people. Excellent products. It's just that they're... well... twisted and cruel. You see their RoboJoust event? We didn't take them serious when they said it was to be performed 4' off a concrete floor. But here's the proof. They're actually building the table that high off the ground. Next […]
