Path-Q Solar
What should I do before requesting quotes if I expect major changes to my home's electrical service?
Answer
Identify and document the expected electrical changes before comparing solar quotes, and ask installers to price the solar work separately from any service, panel, meter, or wiring upgrades. If the changes are not yet defined, treat quotes as preliminary.
Key points
- Gather information about planned loads such as an electric vehicle, heat pump, electric water heating, additions, or other major equipment.
- Ask whether the proposed system requires changes to the service capacity, main panel, meter arrangement, or interconnection equipment.
- Request itemized base and alternate prices, including who is responsible for confirming upgrade requirements.
What it depends on
- The type and timing of planned electrical loads
- Existing service capacity and panel condition
- The design and interconnection requirements of the proposed system
Risks and trade-offs
- A system designed before major loads are known may need redesign or may leave too little usable capacity.
- Waiting for every future decision can delay quoting, while proceeding too early can create change orders.
- Electrical work may involve separate approvals, scheduling, and costs that are not included in a solar quote.
Information you may need
- Recent electrical service or panel information
- A list of planned major electrical equipment and expected installation dates
- Any available utility or electrician guidance about service capacity
Your next step
What to do next
Prepare a one-page list of existing and planned electrical loads, then ask at least two installers to provide comparable quotes with electrical-upgrade assumptions and allowances clearly stated.
