Solar basics
From sunlight to home power
A residential solar system is more than panels. Here’s a simple view of the main parts and what each one does.
Sunlight reaches the panels
Photovoltaic modules convert sunlight into direct-current (DC) electricity.
Inverters convert power
Microinverters convert panel output into the alternating-current (AC) power the home uses.
Your home uses solar first
Available solar electricity serves household loads while the system is producing.
The grid can fill the gaps
The home may draw electricity from the utility when solar production is insufficient.
A standard grid-tied system typically shuts down during an outage for safety. Backup power needs compatible equipment and an appropriately configured battery system.
Equipment
Explore the components
Options depend on design, compatibility, product availability and project requirements.
Financing basics
Compare the written terms
Review ownership, payments, fees, utility charges and contract responsibilities instead of relying on a single monthly figure.
Solar loan or cash purchase
Understand ownership, price, financing fees and payment schedule.
Solar lease
Review lease payments, escalators, service provisions and transfer terms.
Roofing financing
Verify current lender terms, promotional conditions and approvals.
Rates, offers and approval vary. Confirm current terms in the actual lender or program documents.
Roofing + solar
Why roof condition matters before solar
Your roof and solar system share the same surface. Reviewing roof condition early can help clarify the right sequence, scope and mounting details for both projects.
Ask about roof decking, ice and water protection, underlayment, flashing, starter materials, shingles and ventilation—not only the visible shingle layer.
