Each frame has a small combiner box connecting the 4 panels with 12 gauge cable to a 10 gauge uplink to the master combiner box. The master combiner uplinks to the house with 6 gauge. See pics at http://ph.groups.yahoo.com/group/12VDC_Power/photos/browse/5156?c=
They bought a 40' shipping container to put belongings in while the house is being finished, so we put a temporary pv system on that as well for internal lighting.
We go back next weekend to fix the wind turbine and install some ground lines for the panels.
June is the wet season in Ghana, but here in Accra, the capital, the morning rain has ceased. As the sun heats the humid air, pillars of black smoke begin to rise above the vast Agbogbloshie Market. I follow one plume toward its source, past lettuce and plantain vendors, past stalls of used tires, and through a clanging scrap market where hunched men bash on old alternators and engine blocks. Soon the muddy track is flanked by piles of old TVs, gutted computer cases, and smashed monitors heaped ten feet (three meters) high. Beyond lies a field of fine ash speckled with glints of amber and green—the sharp broken bits of circuit boards. I can see now that the smoke issues not from one fire, but from many small blazes. Dozens of indistinct figures move among the acrid haze, some stirring flames with sticks, others carrying armfuls of brightly colored computer wire. Most are children. 
We are working on a number of projects today. It's -25F outside, so it's a good day to stay indoors near the wood stoves. Even the generator wouldn't turn over, even with the recoil start. Brought it in next to the wood stove to thaw out. The worm beds are under construction, and we ordered a inexpensive bucket toilet with lid as one of the food sources for the worms. Many folks use sawdust or peat, but we use recycled Coconut fiber. For info on how it works, read about it at http://weblife.org/humanure/default.html
