Ramius Posted October 4, 2016 Author Share Posted October 4, 2016 Thanks Jaco, The Systems certainly keeps the lights on and make 38KW/h on a good day, but I have a shading problem on the one string in the winter, which was a design compromise when I designed the house, but watch this space, I am busy cooking up a new plan.
