How United Solar Works and What to Know Before You Install

United Solar is a solar installer that handles both equipment and financing

United Solar is a residential solar company that installs rooftop systems and offers its own financing options rather than requiring you to bring your own lender. The company operates in multiple states and handles the full process: site assessment, system design, installation, and paperwork with your utility. Unlike some installers that work only with third-party lenders, United Solar finances many of its installations directly, which can simplify the approval process if you're approved for their in-house program.

The company focuses on homeowners who want to reduce electricity bills through solar power. United Solar's model means you're working with one company for both the equipment and the money to pay for it, rather than coordinating between an installer and a separate bank or solar loan company.

Key Takeaways

• United Solar installs rooftop solar systems and offers in-house financing, so you may not need to find a separate lender.
• The company serves multiple states but not all regions, so you'll need to check whether your address is in their service area.
• Installation typically includes a free site assessment, system design, permitting, and connection to your utility grid.
• United Solar's financing terms, interest rates, and down payment requirements vary based on your credit profile and the system size.
• You should compare United Solar's quotes and terms against other installers and financing options before committing.

What United Solar's installation process looks like

The process usually starts with a free site assessment, where a United Solar representative visits your home to evaluate your roof, sun exposure, electrical setup, and current energy use. They measure your roof, check for shading from trees or nearby structures, and review your utility bills to understand how much electricity you consume. This assessment determines whether your roof is suitable for solar and what size system would make sense for your household.

After the assessment, United Solar designs a custom system for your roof and provides a quote that includes equipment costs, installation labor, permitting fees, and financing terms if you choose their in-house program. If you move forward, the company handles the paperwork with your local building department and utility company. Installation itself typically takes one to three days, depending on system size and roof complexity. Once installed, United Solar coordinates the final inspection with your city or county and the utility's approval to connect the system to the grid.

How United Solar's financing works

United Solar offers loans through its own financing program, which means the company itself is the lender rather than referring you to a bank. This can speed up approval because you're not waiting for a third-party lender to review your application. The company evaluates your credit score, income, and debt-to-income ratio to determine whether you may have access to and what interest rate and terms they'll offer.

Loan terms, down payment amounts, and interest rates depend on your credit profile and the system cost. United Solar typically offers loans with terms ranging from several years to longer periods, though the exact options vary. Some customers may also be able to use a home equity line of credit, cash, or other financing methods outside United Solar's program. You should ask United Solar for their current rates and terms during the quote process, and compare those against other solar installers and lenders before deciding.

Service areas and whether United Solar operates near you

United Solar does not serve every state or every address within the states where it operates. The company's service territory has changed over time and varies by region. To find out whether United Solar can install at your address, you can enter your zip code on their website or contact them directly for a service area check. If they don't serve your location, they can often refer you to other installers in your region.

Even if United Solar operates in your state, local permitting rules, utility interconnection policies, and roof conditions can affect whether a system is practical for your home. The free site assessment will clarify what's possible at your specific address.

Comparing United Solar to other solar installers

United Solar is one of many residential solar companies operating in the United States. Other installers include Sunrun, Vivint Solar, Tesla Energy, and regional companies that may serve your area. Each company differs in financing options, warranty terms, equipment brands, and customer service reputation. Some installers work with multiple third-party lenders, while others offer in-house financing like United Solar does.

When comparing installers, look at the total cost of the system (including financing charges over the loan term), the warranty coverage for equipment and installation labor, the company's track record with customer service, and whether they handle all permitting and utility coordination or pass some of that work to you. Getting quotes from at least two or three installers lets you see how United Solar's pricing and terms stack up. Online reviews and the Better Business Bureau can provide insight into customer experiences, though individual reviews should be read with the understanding that dissatisfied customers are more likely to post than satisfied ones.

Warranties and what they cover

United Solar typically includes a warranty on the solar panels themselves (usually 25 years) and a separate warranty on the inverter, which converts the panels' direct current into the alternating current your home uses (usually 10 to 15 years). The company also offers a workmanship warranty covering the installation labor, though the length of that warranty varies. You should ask United Solar for the specific warranty documents during your quote so you understand exactly what's covered, what's excluded, and how long each warranty lasts.

Warranties cover defects in materials and workmanship but typically do not cover damage from storms, accidents, or normal wear over decades. If a panel fails or an inverter stops working within the warranty period, United Solar or the manufacturer will repair or replace it at no cost to you. After the warranty expires, repairs become your responsibility, though solar equipment generally lasts 25 to 30 years or longer.

Questions to ask United Solar before you commit

Before signing a contract, ask United Solar for a detailed quote that breaks down equipment costs, labor, permitting fees, and financing charges separately. Request the full warranty documentation and ask what happens if you sell your home — can the new owner assume the loan, or do you need to pay it off? Ask whether the company handles all permitting and utility coordination or whether you'll need to manage any of that yourself. Clarify what happens if your roof needs repair or replacement during the solar system's life, and whether United Solar can remove and reinstall panels if roofing work is needed.

Ask about the company's timeline from contract signing to installation, and what happens if there are delays. Request references from recent customers in your area if possible. Finally, ask United Solar to explain how your electricity bill will change once the system is installed — how much you'll save, whether you'll still owe a monthly utility bill, and whether your utility offers net metering (crediting you for excess power your system sends to the grid).

Frequently Asked Questions

Does United Solar work with renters or only homeowners?

United Solar installs on roofs you own, so the company works with homeowners, not renters. If you rent, you would need your landlord's permission and agreement to have solar installed, which most landlords decline because the system becomes part of the property and affects its value and insurance.

What if I want to move before my United Solar loan is paid off?

This depends on your loan agreement. Some solar loans can be transferred to the new homeowner, while others require you to pay off the balance when you sell. Ask United Solar whether your loan is assumable before you sign, and request the specific terms in writing. If the loan isn't assumable, you'll need to factor the payoff into your home sale proceeds.

How much money will I actually save on my electricity bill?

Savings depend on your current electricity rate, how much sun your roof gets, your system size, and how much electricity your household uses. United Solar should provide an estimate during the quote process based on your utility bills and roof conditions. Actual savings may vary from year to year depending on weather and changes to your utility's rates. You can ask United Solar for references from customers with similar homes in your area to see what they've experienced.

What if my roof needs replacement after solar is installed?

If your roof needs work, United Solar can remove the panels, the roofer can do the work, and United Solar can reinstall the panels. This adds cost and time, so it's worth having your roof inspected before solar installation if it's more than 15 years old. Ask United Solar whether they charge a fee to remove and reinstall panels, and get that in writing.

Can I use solar tax credits or rebates with United Solar?

Federal tax credits and some state or local rebates may be available for solar installations, but the rules vary by location and change over time. United Solar can explain what credits or rebates may apply to your system and whether the company handles the paperwork or whether you file for them yourself. Ask about this during your quote so you understand the true cost after any credits are applied.
