Adding home charging alongside another electrical upgrade?
If your DuPont project combines an EV charger with a heat pump or kitchen renovation, have the equipment included in one load calculation. Ask for each new circuit and any panel or service changes to be itemized. The charger position and cable route should suit the way you park and use the garage.
Considering solar when the roof is being replaced?
Coordinate the roof work before committing to the solar installation schedule. Have the proposal identify the array area, roof preparation and electrical connection. Include annual electricity use and any equipment additions so the proposed system reflects the home you expect to use.
Include the panel connection in a solar estimate
For solar on a DuPont home, have the electrical connection considered alongside the roof layout. The proposal should identify whether the existing panel can accommodate the design and which panel changes are included if needed. When a panel replacement is already planned, coordinate both scopes before equipment is selected. Utility interconnection and inspection responsibilities belong in that combined sequence rather than being left to a later installer.
Use annual electricity consumption, including new equipment
A solar proposal can be compared more usefully when its estimated production is placed beside the home’s expected annual use. If you are adding an EV charger or electric heating, share those changes with the installer. Keep current consumption and future equipment assumptions distinct. Ask to see the roof area and shading assumptions used for the design, along with any roof preparation that must happen first.
Compare the installation you want finished
A combined solar and electrical proposal should separate the array, inverter, panel work and any charging circuit. Include roof-related work, electrical routing and restoration so the total reflects the completed installation. If battery backup is a goal, have the compatible equipment and supported loads specified separately. Request an estimate with the roof work you anticipate, electricity-use records and any vehicle or heating equipment already selected.
