Solar Services — Find the Right Help for Your Home
Solar is a long-term decision that depends on your roof, your electricity use and how the system is paid for. This page explains what to understand before you start talking to solar companies.
What should I know before getting solar?
Three things drive most solar outcomes: the condition and orientation of your roof, how much electricity you actually use, and how the system is financed — cash purchase, loan, lease or power purchase agreement. Incentives and net-metering rules are set by your state and utility, so confirm what applies at your address.
Scope
What kind of solar help do you need?
Knowing which conversation you are having makes every later step easier.
Rooftop solar installation
Panels mounted on the roof with an inverter and interconnection to your utility.
Ground-mount systems
An option where roof area, shading or roof condition makes rooftop mounting impractical.
Battery storage
Added to store production for use later or during outages, depending on the equipment and utility rules.
Solar with roof work
Coordinating panel installation with roof replacement so panels are not installed over a roof near the end of its life.
System assessment
Reviewing shading, orientation, electrical panel capacity and your usage history.
Timing
When should you contact a professional?
Your roof is near the end of its service life
Replacing a roof under existing panels means removal and reinstallation. Sequencing matters.
Your electricity use has changed
An added EV, heat pump or home office changes what a system needs to cover.
You want to compare financing structures
Ownership, loans, leases and PPAs have very different long-term implications.
You need to understand local rules
Interconnection, permitting and net-metering terms are set locally.
Selection
How to find the right service provider
Confirm they serve your area
Service areas vary widely. Checking coverage first avoids conversations that cannot go anywhere.
Confirm they handle your type of work
Many providers specialize. A company that does one kind of project well may not take on another.
Ask for a written scope
A written description of the work makes it possible to compare providers on something other than a single number.
Verify credentials yourself
Licensing and insurance verification belongs to you as the homeowner. Ask for documentation and check it.
Compare more than one option
Differences between providers usually trace back to differences in what is included, not to the quality of the sales conversation.
What information should you have ready?
- Your ZIP code
- Type of property (single-family, condo, townhome, mobile home, commercial)
- A short description of the problem or project
- Approximate size of the affected area
- How urgent the situation is
- Whether you own or rent the property
- Twelve months of electricity usage from your utility bills
- Roof age, material and general condition
- Whether the roof is shaded during the day
- Your electrical panel rating, if you know it
Questions to ask before hiring
- What system size do you recommend for my usage, and how did you arrive at it?
- What assumptions are behind the production estimate?
- How does my roof condition affect the installation?
- Who handles permitting and utility interconnection?
- What financing structures do you offer, and who owns the system in each?
- What happens if I sell the house?
- What warranty covers the panels, the inverter, the roof penetrations and the labor?
- Who services the system after installation?
Verification
What to check before work begins
- Confirm the licensing that applies in your state or municipality and ask to see it
- Ask for proof of liability insurance and, where applicable, workers' compensation
- Get the scope of work in writing before any work begins
- Confirm what is included and what is billed separately
- Confirm payment terms and avoid large up-front payments you are not comfortable with
- Ask what warranty applies to labor and to materials, and get it in writing

Common homeowner questions

Should I replace my roof before installing solar?
If the roof is near the end of its service life, many homeowners replace it first. Removing and reinstalling panels later to re-roof adds cost and coordination that can be avoided by sequencing the work.
