Home money
Decide whether rooftop solar fits your house and your numbers
Put the roof, electric bill, production estimate, contract, warranty, and future plans on the same page before signing.
At a glance
Solar value depends on the specific home, utility rules, design, price, financing, tax eligibility, and how long you expect to own the system. Compare the underlying assumptions, not just a projected payment.
Why we're telling you this
What this advice is based on
This framework separates site fit, production, utility rules, incentives, equipment, contract structure, and total cost. 4Homes does not rank installers or assume that solar is right for every home.
What to check
- Gather at least twelve months of electricity use and understand current rate structure and fixed charges.
- Confirm roof age, condition, usable area, orientation, shade, structural questions, and likely replacement timing.
- Compare system size, equipment, production model, degradation, interconnection, and storage assumptions.
- Separate cash price, financed price, interest, fees, lease or power-purchase terms, and escalation clauses.
- Verify current utility, tax, permitting, and incentive rules with authoritative sources and qualified advisers.
What to watch for
- Savings projections that assume utility increases or production without showing the model.
- A tax credit presented as guaranteed cash regardless of individual eligibility.
- Financing described only through a monthly payment while dealer fees and total repayment remain unclear.
What to do next
- 01Compare a no-solar baseline with more than one realistic system scenario.
- 02Resolve roof and electrical scope before signing a long-term agreement.
- 03Have contract, lien, transfer, warranty, removal, monitoring, and service terms reviewed before the cancellation window closes.
If cost becomes part of the decision
Understand the project before choosing how to pay.
If ownership financing is being considered, compare the cash price, financed price, total repayment, tax assumptions, and home-equity alternatives separately.
