We begin logging how the amount of power generated when the yield exceeds 10 watts. We stop in the evening when the yield falls below 10 watts. During the day, we only count periods where more than 10 watts are generated.

| Info |
On this page you can find information about the amount of power currently being generated by the solar panels. The maximum yield of our solar plant is 260 watts. To counterbalance the effects of aging, the solar panels have a slightly higher yield when they leave the factory. As a result, our two panels can produce a good deal more energy than their specified nominal capacity when they get full sunlight. Their efficiency depends on the intensity and the incident angle of the sunlight. Power generation data is logged every day from 0:00 until 23:59 (24-hour time format) and then added to the statistics page.
We begin counting the time that power is produced as soon as the yield exceeds 10 watts. We stop counting when it drops below 10 watts. If the yield rises above 10 watts again at a later time, the ending time is automatically updated. The average power generated is logged every 7.5 seconds. If that average value is greater than 10 watts, 7.5 seconds are added to the time sheet for total power generated. We set the limit to 10 Watts, because the solar regulator also uses some power and the battery bleeds a little bit of power as well. Additionally, the PC's power supply draws a standby current.
