I have ten years experience with my remote cabin solar power system which has taught me a lot about solar panels. The rule of thumb is that you can expect a panel output to be 80% of rated because the rated values are laboratory perfect measurements. I measured the volts and amps out on my Rich 250 expecting a bit more than 5 amps but in fact was seeing 6 amps or nearly 90% of rated. Volts out were 40 DC which exceeded the rated value by 8%. This was in direct sunlight with clear air at midday and 300ft ASL.
I commend Rich for their packaging methods too. The carton was innovative because of its padding and easy open fastening and yet maintaining a slim form factor in height, width, and thickness.
My only regret is that it is 4 inches shorter than my legacy system with the crippled panel I plan to replace with this one. That means the Rich panel will be a little non-symmetric along side the other panels I have mounted on a rotatable panel column. Oh, well, only me and the cows and wildlife will see that.
