I have used Excel Solar on three occasions the first I was advised to install a 3 kilowatt inverter and 1kilowatt of PV panels to the electricity grid, by installing the larger inverter I could add extra PV panels as I could afford them. On the second and third occasions Excel Solar installed 1 kilowatt of PV panels each time about 1 year apart. Having done this my power bill has been reduced greatly. I found Excel Solar use quality components and their installs professional, better looking in layout and appearance. There is no hard sell from Excel Solar only good advice and recommendations that help you reduce your carbon footprint and power costs. Best of all Excel Solar are a local professional, knowledgeable business who care and stand by their work and product.
