Dominion Energy South Carolina – FAQs*

Who is Clean Energy Co?

Clean Energy Co (CEC) is a renewable energy solutions provider that builds, operates, and maintains clean energy solar facilities for utilities and the communities they serve. CEC pioneered the model of delivering clean power generation through medium-scale community solar facilities that are collectively shared by participating utility customers. CEC has partnered with Dominion South Carolina to offer their uniquely branded RooflessSolar™ product, commonly known as community solar, to Dominion Energy South Carolina's electric customers.

What is RooflessSolar (community solar)?

With CEC’s RooflessSolar (community solar), solar panels are located in an open field and connected to the Dominion Energy South Carolina's grid, not on your roof or property. Electricity from the RooflessSolar array is distributed across Dominion Energy South Carolina's electric grid, and participating customers are credited monthly on their utility bills for the power produced by their proportional share of the array. Community solar arrays enable Dominion Energy South Carolina's electric customers to benefit from clean solar energy, regardless of the customer's ability to install solar at their service address. Program participants, including renters, can enjoy the benefits of solar without installing anything on their roof or property.

What is the Dominion Energy South Carolina Community Solar program?

This program is the ongoing initiative by Dominion Energy South Carolina in partnership with CEC to provide effective Community Solar solutions to residential customers and eligible nonresidential Dominion Energy South Carolina's electric customers. Visit to learn more.

Who can participate?

Community solar is available to current Dominion Energy South Carolina's electric customers – residents (homeowners and renters), schools, churches, or municipalities.

How can I participate?

There are two different ways to participate, so you can go solar in a way that best fits your needs and your budget - by Subscribing (similar to renting a home for a monthly fee) or by Purchasing. Subscribe at a low monthly rate to see instant savings, or purchase panels and see greater savings over the 20-year term of the program.

How does CEC’S RooflessSolar Subscription option differ from the Purchase option?

If you decide to participate in the community solar program, Dominion Energy South Carolina will credit all participants through on-bill credits in exchange for putting solar energy on to their grid, regardless if you subscribe or purchase. If you subscribe, you receive $0.01 per kilowatt-hour (kWh), and you start seeing savings soon after the RooflessSolar array is interconnected to the grid. If you purchase panels, you receive $0.10 per kWh each month, and see a total payback after about 13 years with pure savings each year thereafter.

There are opportunities for subscription customers to convert to ownership in years 6, 11, 16, and 20, allowing customers to purchase panels at market value and maximize their benefits.

How much can I purchase or subscribe to?

You can purchase or subscribe to enough energy to off-set up to 100% of your electrical usage in kilowatt-hours (kWh) without exceeding 26 kilowatt (kW) dc / 20 kWac for electric residential customers and 1,300 kWdc / 1,000 kWac for schools, churches and municipalities.

How much does it cost to participate?

Subscription: For subscription customers, there is a monthly fee of $0.20 per Kilowatt of solar capacity subscribed. The average subscriber would pay about $15/year* and fees are applied to your existing monthly Dominion Energy South Carolina bill and spread across your monthly statements. Monthly credits are expected to be greater than monthly fees providing for instant saving.

Purchase: A single solar panel (117.5 Watts DC) costs $264. The average customer will require approximately 55 panels for a total off-set (enough to produce all the power you need). A monthly credit of $0.10 per kWh will be applied to your electric bill. Cumulative monthly credits are expected to cover your purchase price by the 13th year of the program after which 100% of your bill credits can be applied to your monthly usage charges.

What happens after 20 years?

After 20 years, the program may be extended for an additional 15 years and bill credit rates will be adjusted to match Dominion Energy South Carolina's avoided cost rates at that time.

The purchase version of the community solar contract with CEC states that customers are purchasing an “interest” in selected solar panels. What does that mean?

Under the purchase option, customers receive an interest in the solar output (actual generated electricity) of their selected solar panels. CEC retains ownership of the panels. In the sixth year, customers may purchase the panels outright on an as is basis under the purchase option price outlined in the contract. At that time, the customer would also need to sign an ownership agreement and CEC will then convey ownership of the selected solar panels by bill of sale. Customers who do not want to purchase full ownership may opt to simply retain the purchase interest option for the full term of the contract. Dominion Energy South Carolina's bill credit of $0.10 per kilowatt hour remains the same for the full term whether or not the customer elects to purchase the panels outright.

Retaining the ownership of the solar panels through the sixth year allows CEC to fully realize the federal Investment Tax Credit (ITC) available to investors for qualified advanced energy projects. The savings that CEC receives from the tax credit is reflected in the price of the solar panels available through the community solar purchase option.

How does participation in RooflessSolar save me money?

If you subscribe, CEC estimates that the average subscribing Dominion Energy South Carolina's residential customer would save approximately $103 in the first year, and $1,959 over the twenty-year term of the program.*

If you purchase panels, the average Dominion Energy South Carolina's residential customer choosing to offset all their electric use would purchase 55 solar panels for a total cost of $14,540, and see a payback of $22,693 over the course of 20 years.* The bill credits are estimated to completely pay for the cost of the system in just under 13 years, with a total payback is 156%.

How do bill credits work?

Each month, CEC will calculate the number of kilowatt-hours (kWh’s) attributable to each customer in the RooflessSolar™ arrays based on a pro rata share of the output. Once the kWh production for each customer is determined, Dominion Energy South Carolina will apply a credit to your bill that is equal to the number of kWh's produced. Subscription customers earn $0.01 per kWh, while purchase customers earn $0.10 per kWh. The credits are then applied to your bill, reducing the total costs owed to Dominion Energy South Carolina. If you ever have more credits than what you owe, your credits will carry forward and be applied to future months as needed.

Sample Credit Calculation Subscription Purchase
Customer Solar Production 937 kWh 937 kWh
Credit Rate $0.01 per kWh $0.10 per kWh
Dollar Credit Applied to Bill $9.37 $93.70

Will I get the same amount of credits applied to my electricity bill each month?

Your bill credit will vary from month to month based on the solar panels’ production. In months when there is more sunshine, you will have a higher bill credit, and in cloudier months, you will have a lower bill credit.

Am I still connected to Dominion Energy South Carolina?

Yes. With community solar, you are still connected to your local utility’s electric grid.

How are ongoing maintenance expenses addressed?

Community solar arrays are 100% maintained by Dominion Energy South Carolina at no cost to you.

Why is the contract so extensive?

We provide our customers with an extensive contract in order to accurately detail the terms and protect all parties involved – CEC, the utility, and the customer.

Am I signing a contract with Clean Energy Co or Dominion Energy South Carolina?

The agreement will be between you and Clean Energy Co . You will be receiving the credit through your Dominion Energy South Carolina bill as outlined in the Rider to Retail Rates – Community Solar.

What if I change my mind before the community solar array comes online?

Once you’ve signed your agreement, it is effective and you will need to request termination. If you’ve elected to purchase panels, your deposit will be fully refunded when you terminate before the array is activated and generating power.

Why a 20-year commitment? Can I get a shorter term?

As a community solar participant, you can always exit your commitment by referring a new customer or paying a termination fee. System capacity (your subscription or purchase amount) that is successfully transferred to a referred customer will incur no termination fee during the initial 20 year term. Any system capacity that is not successfully transferred to a referred customer incurs a termination fee of $50/kW, which is designed to cover the cost of marketing and sales to acquire a new customer. After 20 years, the program may be extended for an additional 15 years and bill credit rates will be adjusted to match Dominion Energy South Carolina's avoided cost rates at that time. Upon being notified of the program’s extension and its terms, you may choose to discontinue participation in the program and incur no termination fees.

Are there any tax incentives associated with RooflessSolar?

There is an IRS federal tax rebate known as the Solar Investment Tax credit, which Clean Energy Co collects. CEC uses the monetary savings associated with the tax credit and passes them on through competitive pricing.

What happens if I move?

If you move within Dominion Energy South Carolina's electric service territory, you can take your solar bill credits with you to your new location. If you move outside of Dominion Energy South Carolina's electric service territory, you have two options:

  • Identify and arrange for a transfer of your subscription or purchase to another eligible Dominion Energy South Carolina customer. We will assist with all necessary transfer and/or re-sale paper work. No fee.
  • If you’ve subscribed, simply provide notification that you intend to end your participation in the program - $50/kW termination fee will apply.

What kind of environmental impact am I having by participating in the program?

Over the lifetime of the program the average participant’s share of the array will provide the equivalent environmental benefits of planting 698 trees, a reduction of 513,000 car miles driven, and 452,000 lbs. of CO2 emissions avoided. *

What is the "lifetime" of the system?

The program is 20 years, and all savings and cost estimates are based on 20 years. However, the panels in the community solar array are capable of producing power for much longer. After 20 years, the program may be extended for an additional 15 years at CEC’s discretion.

How does RooflessSolar work for schools, churches, and municipalities?

If you are a tax-exempt entity participating in RooflessSolar, all of the above information applies to you. Pricing and credit rates are the same, but CEC will work with you on an individual basis to provide a custom proposal based on your specific electric usage and budget. Contact our commercial support team at for information on how RooflessSolar can save your organization money.

*Estimates are based on the average household electric usage of 1,000 kWh a month. Please speak with a Community Solar Specialist to receive savings and environmental benefits specific to your electric usage. Consult your proposal and/or contract for specific terms and conditions.
