  1. Ok,I wonder if our software can be considered this.
  2. Dear sir: For the bi-facial module system , when calculating the cable loss of strings, should the current on the rear side of the modules be considered in our software? thanks!

    tilt problem

    OK, u are welcome
  4. Dear sir: I found that the inclination angles of the two are not the same. Is it a bug?THANKS
  5. Dear sir: Can you take a look at this problem? Why is the backside mismatch loss calculated separately from the front side, rather than being added to the front side like irradiation. thanks!
  6. When I completely shade the front side of the module and allowed the back side to receive light, I found that the loss due to weak light was relatively high.
  7. ok,I agree with your viewpoint, but do you think this calculation is reasonable? if the fornt side of module receive irradiance of 1000 W/m², and the rear side of module receive irradiance of 200 W/m², front side:(f × 22- f × 22) / (f × 22) = 0% (relative) rear side:(f × 21.34 - f × 22) / (f × 22) = -3% (relative)
  8. I understand. What I mean is, if the irradiation intensity on the back of the module is relatively low while that on the front is relatively high, so does it imply that the low-light performance of the rear side is worse?
  9. Because the irradiance of the front side or the rear side of PV module will be different, in this case, there will be a difference in conversion efficiency between the front and back sides,with respect to 1000 W/m².
  10. Dear sir: Has the software taken into account the low-light performance on the rearside of bifacial module? thanks
  11. Dear pvsyst team: If I have an irregular trackers system, with some different pitches and GCR, what is the difference between the reference trackers and automatic mode ( deselecting the reference pair of trackers)?what is the automatic mode? thanks!
