Am I correct in understanding you have an aquaponics system that runs with solar panels?
If so, I interested in knowing how it has worked out for you so far. I am researching the possibility of running a CHOP II system using Murray Hallam's design purely on solar. So far the folks I've asked about it say it will cost thousands of dollars just for the PV system.
Glad to hear that you love food in Guangdong. Guangdong is in southern China, and Shandong is in northern China, so the food in the two area is very different. But both of them are delicious.Welcome to Shandong and try Shandong Cuisine, haha!
