Erus Energy: What to Know About This South Carolina Solar Company

Who Erus Energy Is and What They Do

Erus Energy is a solar installation company operating in South Carolina that designs and installs residential solar panel systems.

What to Ask Any Solar Installer, Including Erus Energy

When you contact a solar company for a quote, you should ask the same questions regardless of which installer you are considering. Request a detailed breakdown of the system cost, including equipment, labor, and permitting fees. Ask whether the price includes removal and disposal of your old roof materials if your roof needs replacement before installation. Find out what financing options they offer—cash purchase, loans, leases, or power purchase agreements (PPAs)—and what the terms are for each.

Ask about the warranty on the solar panels themselves (typically 25 years) and the warranty on the inverter and installation work (usually 10 years or less). Request the names and contact information of recent customers in your area who can speak to their experience. Confirm that the installer will handle all permitting and inspections with your local government, and ask what timeline they estimate from contract to system activation. Also ask what happens to your contract and warranty if the company is sold or goes out of business.

How Solar Installation Works in South Carolina

The solar installation process in South Carolina typically begins with a site assessment. The installer visits your home, examines your roof's condition and angle, checks for shading from trees or buildings, and reviews your electricity bills to understand your energy use. They then design a system sized to meet your needs and provide a quote.

Once you sign a contract, the installer applies for permits from your local building department and your utility company. This step can take several weeks. After permits are approved, the installation crew mounts the racking system to your roof, installs the solar panels, runs electrical wiring, and connects the inverter (which converts the sun's DC power into AC power for your home). A final inspection by the local building department and utility company must happen before the system is activated. The entire process from contract to first power generation usually takes two to four months, though timelines vary.

Understanding Costs and Financing Options

The cost of a residential solar system in South Carolina depends on the system size (measured in kilowatts), the quality of equipment, your roof's condition, and local labor rates. A typical residential system ranges from 5 to 10 kilowatts. You should get quotes from multiple installers to compare pricing, as costs and financing terms vary significantly.

Most solar installers offer several ways to pay: outright purchase with cash, a solar loan (which you repay over time), a lease (where you pay a monthly fee to use the system), or a power purchase agreement or PPA (where you pay only for the electricity the system generates). Each option has different upfront costs, long-term savings, and tax credit may be able to access. For example, if you purchase the system outright or with a loan, you may be able to claim federal and state tax credits. If you lease or use a PPA, the installer typically claims the credits instead, which may lower your monthly payment but means you do not receive the tax benefit.

Tax Credits and Incentives Available in South Carolina

South Carolina offers a 30% federal Investment Tax Credit (ITC) on the cost of a solar system if you own it outright or finance it with a loan. This credit reduces your federal income tax liability dollar-for-dollar. The credit applies to the full installed cost, including equipment and labor. You claim it on your federal tax return in the year the system is activated.

South Carolina also allows a state income tax deduction for solar energy systems, though the details and limits change periodically. Some utility companies in the state offer net metering, which means excess electricity your system generates flows back to the grid and you receive a credit on your bill. Not all utilities offer this, so check with your local utility company about their specific policies. These incentives can significantly reduce the effective cost of going solar, but they are subject to change, so verify current programs before making a decision.

Questions to Ask Before Signing a Contract

Before you commit to any solar installer, including Erus Energy, review the contract carefully and ask for clarification on any terms you do not understand. Confirm the total system cost, what is included in that price, and what costs might arise later (such as roof repairs or electrical upgrades). Ask whether the price is fixed or if it could increase before installation begins.

Request a written explanation of the warranty coverage—what parts are covered, for how long, and what you must do to maintain the warranty. Ask how the company handles system monitoring and maintenance, and whether there are ongoing fees. Find out what recourse you have if the system underperforms or if equipment fails. Get the installer's license number and verify it with the South Carolina Department of Labor, Licensing and Regulation. Ask for references from customers who had similar systems installed at least a year ago, so you can hear about their real-world experience.

Comparing Erus Energy to Other South Carolina Installers

Erus Energy is one option among several solar installers operating in South Carolina. Other companies range from large national firms to smaller regional and local installers. Each has different pricing, equipment choices, warranty terms, and customer service approaches. Getting quotes from at least three installers allows you to compare not just price but also the quality of communication, the detail in their proposals, and how well they answer your questions.

When comparing, look beyond the lowest price. A cheaper quote might use lower-quality equipment, offer a shorter warranty, or include fewer services. A higher quote might include premium panels, longer warranties, or more comprehensive monitoring. Read online reviews from customers in South Carolina, but remember that reviews can be biased—focus on specific details about the installation process, customer service, and system performance rather than general praise or complaints.

Frequently Asked Questions

Does my roof need to be replaced before solar installation?

Not necessarily. If your roof is in good condition and has at least 15 to 20 years of life remaining, solar can be installed directly on it. If your roof is nearing the end of its life, many installers recommend replacing it first to avoid removing the panels later. Ask the installer to assess your roof's condition during the site visit and include any necessary repairs in the quote.

What happens to my solar system if I sell my house?

If you own the system outright or financed it with a loan, the system typically transfers to the new owner, and you should disclose it during the sale. If you leased the system or have a PPA, the new owner would need to assume the lease or agreement, or you would need to pay off the remaining balance. Discuss this scenario with your installer and review the contract terms before signing.

How much money will I save with solar?

Savings depend on your current electricity bill, the size of your system, how much sun your roof receives, and your utility company's rates. A system that covers 100% of your electricity use could save you hundreds to thousands of dollars per year, but actual savings vary widely. Ask the installer for a detailed estimate based on your specific home and electricity use, and ask for references from similar customers to understand realistic savings.

What if the solar company goes out of business after installation?

Your system will continue to work, but you may lose access to monitoring services or warranty support. Before signing, ask the installer what happens to warranties and service agreements if the company closes. Some warranties transfer to a new service provider, while others do not. This is an important question to clarify in writing before you commit.

Can I install solar myself instead of hiring a company?

South Carolina allows homeowners to install their own solar systems, but it requires electrical permits, building permits, and inspections from your local government and utility company. You must follow all electrical codes and safety standards. Most homeowners hire professional installers because the technical and permitting requirements are complex, and mistakes can be costly or dangerous. If you are considering DIY installation, consult with your local building department first to understand all requirements.
