I'm a Solar System design professional. I design residential, commercial and industrial projects up-to 500kW. I use multiple softwares, including (Sketchup, Autocad, PVsyst, Bluesol..) for designing my system. Your project will be taken care of from the preliminary design to a full detailed shop drawing, and if you're local I take care of installation and commissioning. If you're not local, you can give me your home coordinates, and using google earth I can give you an estimate of how much PV your space can take, with a complete final analysis and return on investment. You can check my portfolio to get a more detailed idea of what I do.
