How We Chose the Top Solar Companies
We researched and analyzed dozens of solar panels and solar installation companies. We then formulated a rating system based on each solar installer or manufacturer’s services and products. We weighed several significant factors, including the quality and type of solar panels offered, the customer support network, warranty lengths and limitations, and additional benefits such as mobile apps for monitoring and customer service.
Speaking directly to representatives, we determined how each solar company personalizes its solar panel installation for each home. We also analyzed each company’s warranty options to ensure their product and performance guarantees match or exceed industry standards.
We evaluated each provider based on their rating and history with the Better Business Bureau (BBB) to determine reputation. In addition, we analyzed the 100 most recent Google Reviews for each provider across various locations and branches.
It’s important to do thorough research when making such a big investment in solar. We suggest carefully reading provider websites, considering what customer reviews have to say, and getting a free quote before committing to a company.
Though all companies on our list are quality providers, we recommend SunPower and Blue Raven Solar for their reputation and energy-efficient solar panels. Read our solar panel cost guide to get an idea of how much you can expect to pay for a solar energy system.
Solar Installation Process
Most solar installations follow this or a similar process after your system’s design is approved:
- Site evaluation: An installer will visit your home to confirm the planned design and estimate the scope of work. This person or their team will also inspect your roof, attic, and electrical setup.
- Permit approval: Most states require a permit to install solar panels. Your solar provider should handle the paperwork with your local municipality.
- Installation: Installation typically takes one to three days. You don’t need to be home for it, but we recommend you are so you can ask questions along the way.
- Cleanup: Installers should remove any debris and leave your property in good condition.
- City inspection: Your provider should coordinate with your city to have an inspector come out to check that your system is up to code.
- Utility connection: Lastly, your system must be connected to your local utility system if you’re connecting it to the grid. You’ll apply for connection through your utility company (some providers do this for you), which will also want to inspect your system to make sure it’s in accordance with its utility guidelines. After getting permission to operate, your system can be turned on.
Solar Installation Cost Factors in South Carolina
The average cost of a solar system in South Carolina is roughly $37,000.* The following factors impact this price:
- Company: Solar providers all offer different products and pricing. If the company you buy your panels from is not the manufacturer, the manufacturer will also influence pricing. Better quality and reputation means a higher price tag.
- Panel type: Homeowners can choose between monocrystalline, polycrystalline,and thin-film panels. Monocrystalline panels are recommended for residential solar panel systems because they’re the most efficient, but they’re also the most expensive.
- System size: The more panels you have, the more expensive your system will be.
- Energy efficiency: Expect to pay more for high-efficiency panels.
- Location: Costs vary by city and state. This is compounded by state and local solar incentives.
- Roof pitch: Most solar installation companies charge more for riskier or more difficult installations. Plan to pay more for labor if your roof has a steep pitch, multiple features, or is otherwise difficult to access.

Solar Tax Incentives in South Carolina
South Carolina homeowners interested in going solar can take advantage of a few solar incentives to save money. South Carolina’s state tax credit allows residents to claim 25% of their solar costs as a tax credit. This credit carries over for 10 years.
South Carolina solar customers who own their solar system also qualify for the federal solar tax credit, also called the Residential Clean Energy Credit. This federal tax credit allows you to receive a federal tax deduction equal to 30% of your solar panel installation costs. The 30% rate is available through 2032. It will drop to 26% in 2033 before reducing to 22% in 2034. It will end in 2035 unless Congress renews it.
South Carolinians can also participate in net-metering. Net-metering gives you electricity bill credits for every kilowatt-hour (kWh) of excess solar electricity you send back to the grid.
Getting Solar Quotes in South Carolina
Getting a solar quote is easy. You can typically do it online. Most solar companies have a “Get a Quote” button at the top right of their homepage or near the bottom. Clicking that button will take you to a form to fill out your location, home size, and contact information. Solar providers ask about your home’s location and roof size to determine how suitable your property is for solar.
If you prefer to speak with someone directly, you can call the company and get a quote over the phone by providing the same information. We called SunPower for a solar quote and got one in less than 10 minutes.
Questions to Ask Solar Providers
Take time to thoroughly vet a provider before signing a contract. Your solar project is a major investment. Taking a gamble on the first company you find is not the way to go.
We recommend asking solar panel companies these questions:
- How long have you worked in solar?
- How many systems have you installed? Can I see photos?
- Are you NABCEP-certified, licensed, bonded, and insured?
- What is your business license number?
- Can you share a few customer references?
- Have you worked with my local utility company?
- Does your team do all the work, or do you use subcontractors? How do you quality check the work your subcontractors perform?
- Who do I contact if I have a question or issue? What are turnaround times like to resolve issues?
In addition to questions about the installer, we suggest asking these questions about equipment:
- What are the benefits and drawbacks of this equipment?
- Is this what you have/would put on your home or business?
- What warranty protection is offered for each piece of equipment?
- What do customers complain about with this equipment?
Solar Company Services Provided
Most solar energy companies offer similar services to guide homeowners through the process and make the most of their system. Common solar services include the following:
- Consultation: All companies should offer an initial consultation to discuss your home’s energy needs and whether your property is a good fit for solar. This can often be done virtually or in-person. While virtual consultations are more convenient, be aware that the representative won’t be able to provide as specific or potentially accurate information as if they saw your property in person.
- Design: Providers have in-house design teams to create the best solar panel layout for your roof. You’ll approve this design before installation moves forward.
- Installation: Not all companies use an in-house installation team. Some use third-party companies. Some only install panels, while others also install batteries, electric vehicle chargers, and other equipment.
- Maintenance and cleaning: Many warranties include some sort of maintenance plan through your provider for a period of time. Check to see if a company provides any maintenance or cleaning services after installation.
- System monitoring: If a company has a mobile app, it likely includes some degree of system monitoring. If not—or if you don’t want to monitor your system yourself—check if a provider offers system monitoring to track your panels’ performance.
- Additional services: Some companies partner with third parties to handle services that help your installation run smoothly. Roof repair and pest control are common additional services, as it isn’t wise to install panels on a damaged or infested roof.
