There is a chap in Iloilo whose first name is Brent (german or Austrian), I spoke to him for a few months but never bit the bullet but I will do it this summer ( solar is all he does, he is on Facebook)got a big warehouse and has done big big jobs, very generous with his time and knowledge, felt kind bad wasting his time, but as I say I will do it this summer think it broke down about 600k a lot of the locals quoted a certain output and when i said no they kept upping the output quote.......ha ha ha
