Basil & Rover;
I was with Rich Hagen ( he stays very busy with his work) but may see and post, in Philippines.
I can say this company does seem to have high quality panels.
Installed are the 10watt verities in Luzon,Philippines area. ALL of them worked, packing was top notch and ALL put out as close to rated as I've seen. We could see that they kinda hurried when trying to ship out his large order; some of the connecting wires were shorter than they should've been, but since we had to add wire to them to feed them into the different buildings, it only caused us to buy more wire.
We've been in contact with people who helped and the panels are still working perfectly even with the monsoon rains
I would offer some advice Rich told me about while traveling from Manila to Luzon; go directly to them if you are looking to buy a bunch you will get a better price, otherwise you may find them on feebay cheaper as people upgrade.
I have spoken with them a few times, and they are certainly better at answering questions about the panels and shipping ( when not free) than sunelec.
Hope this helps
