Solar and Heat Pumps: Plan the Loads Together

What homeowners should know

Why electrifying heating and cooling can change the solar system you need. The important details depend on your home, utility, contract and goals, so avoid one-size-fits-all claims.

What to compare

Use written documents and compare the same fields across options. Separate equipment, financing, utility assumptions, warranties and any roof or electrical work so one number does not hide important differences.

A practical next step

Verify the current rules with the relevant utility, government agency, lender or contract documents before relying on a savings or eligibility claim. Keep copies of the proposal, agreement, plans, warranties and approvals.

Questions worth asking

• What assumptions are being used?
• What is included and excluded in writing?
• Who is responsible if something changes?
• Which current utility, lender or government rule applies?
