Should I plan to install conduit for future wiring of my solar array?
Planning the placement of conduit during the new home construction process is a great idea and can save you money on the installation of your solar array. Installing a 2″ metallic conduit from the attic to the location of your electrical load center will allow for DC wiring to be easily installed from your roof-mounted solar array to your load center. If you plan to build a ground-mounted solar array, place conduit underneath any cement, patio, landscaping etc. where the wires will enter the home or meet with the existing utility meter.
