I had done some reading and searching on the net, prior to deciding to go to Slab City. The main reason for me to visit the place was the reputation of one man named Mike, alias Solar Mike, said to be the master of solar cells in USA or maybe the universe.
I know for me, that he is the god of solar cells. It took him 5 sec to see that there was some thing wrong in our camper. It took him 15 min to find out what was wrong. It took him 3 sec to decide when to do it and It took us, plus his assistent, a day to re wier every thing, from the spot where the cells connect to the house on the inside and all the way to the converters and fridge and every thing in between.
It was a Hard job but, way more than worth it. The rest of the trip we did not have to worry about lack of electricity even though it raind for days like in Mexico.
We took the bad old car batteries and changed them out for 6 new MGM batteries that worked great ever after. We also did som rewiering inside and outside (under) the truck. And all this he did for more then a fair amount of money. I know I paid with a smile.
So if you do need to have your solar cells checked, installed or rewired do not hesitate to find solarmike. He is your man.
