    The solar panel looks very good and it’s enormous. I bought 10m of red 6mm cable and another 10m of black cable along with the panel, which I’m using from the panel to the microinverter that I have inside the house to avoid high temperatures. The only problem I have is that I only get a maximum of 260W in these days with maximum sun, no shadows or clouds. I don’t know what’s normal, I was clear that the 400 was peak power, but I thought it would exceed 300W. The microinverter is 700W (GMI 700), I don’t know if that could be the problem, that it’s not very efficient.
