Whether you’re just starting your research or ready to move forward, this guide covers everything you need to know about solar panels for your home — from how they work to what the installation process looks like in Bluffton.

Bluffton Electricity Prices
Electricity costs in Bluffton have been climbing steadily — and understanding that trend can help you make smarter energy decisions for your home.
South Carolina’s average electricity rate rose from 12.9 cents per kWh in 2021 to 14.1 cents per kWh in 2024 — nearly a 10% increase in just three years. While SC rates remain below the national average of 16.5 cents per kWh, the upward trend is clear.
For homeowners exploring solar installation in Bluffton, that rising trend is worth paying attention to. Solar panels generate electricity from sunlight, which can help reduce how much power you draw from the grid — and your exposure to future rate increases.
Over a 25-year panel lifespan, even modest rate increases compound significantly. Bluffton solar panel installation gives homeowners a way to stabilize a portion of their energy costs over the long term, rather than absorbing whatever rate changes come next.
Price of Energy: South Carolina vs National Average
Bluffton Area Utility Providers
In Bluffton, SC, Dominion Energy is the primary electricity provider. Based on the most recent available data (2023), Dominion Energy’s residential rate was 14.4¢ per kilowatt-hour (14.4¢/kWh).
That 2023 rate sits above South Carolina’s state average of 13.70¢/kWh but below the national average of 16.0¢/kWh — meaning Bluffton residents pay more than most South Carolinians, yet less than the typical American household.
Even at 14.4¢/kWh, electricity costs add up significantly for Bluffton homeowners over time. Homeowners who generate their own solar power are naturally less exposed to future rate increases — an important consideration for long-term energy planning.

South Carolina Solar Incentives
Bluffton homeowners have access to several solar incentives in South Carolina that can meaningfully reduce the cost of going solar.
These include a 25% state income tax credit, a full property tax exemption for residential solar systems, a sales tax exemption on equipment, net metering credits, and rebates from Duke Energy for solar and battery installations.
Recent federal legislation eliminated the residential solar tax credit. State and local incentives still apply. Homeowners who lease through Palmetto’s LightReach program see simpler paperwork — Palmetto claims the commercial tax credit and passes savings through lower monthly payments.

South Carolina’s Solar Energy Tax Credit allows homeowners and businesses to claim 25% of their total solar installation cost as a credit against their state income tax liability. The credit is capped at $3,500 per year and carries a lifetime maximum of $35,000 — or 50% of your annual state tax liability, whichever is less. There is no expiration date on this credit, making it available for 2026 installations and beyond.
Eligible technologies include solar photovoltaic (PV) panels, solar water heaters, and solar space heaters installed on a South Carolina property (primary residence or business). The credit is non-refundable, meaning it can only offset taxes you owe — but any unused portion automatically carries forward for up to 10 years, so you won’t lose the benefit if your tax liability is modest in any given year.
To claim the credit, file Form TC-38 (SCH.TC-38) along with your South Carolina state income tax return. You’ll need to include supporting documentation such as your solar system design, permits, and receipts showing total installation costs. Contact the South Carolina Department of Revenue at dor.sc.gov for the most current form and instructions.
South Carolina law provides a full 100% property tax exemption for solar energy systems installed on residential properties. This means that adding solar panels — which can significantly increase your home’s value — will not raise your property tax bill. The exemption applies to solar PV systems with a capacity of 20 kilowatts (kW) or less, and also covers advanced inverters and battery storage systems that are paired with solar.
Both owned and leased solar systems are eligible for this exemption, making it accessible regardless of how you choose to finance your installation. In most cases, the exemption is applied automatically, so no separate application is required. However, it is a good idea to confirm the process with your county assessor’s office to ensure it has been properly applied to your account.
This exemption provides ongoing annual savings for the life of your solar system. For homeowners in Bluffton in areas with higher property tax rates or larger system sizes, the cumulative savings over 20–25 years can be substantial. Visit the South Carolina Energy Office at energy.sc.gov for more information on state-level solar tax incentives.
South Carolina exempts solar energy equipment from the state’s 6% sales tax. This exemption applies at the point of purchase, meaning the savings are immediate and reduce your upfront installation cost without requiring any additional paperwork or tax filing on your part.
For a typical residential solar installation costing between $15,000 and $25,000, the sales tax exemption translates to approximately $800–$1,500 in direct savings. While this may seem modest compared to the state income tax credit, it is an automatic benefit that stacks on top of all other available incentives.
This exemption applies to solar photovoltaic panels, inverters, racking, and other qualifying solar equipment. For more details on eligible equipment and the exemption process, visit the South Carolina Energy Office at energy.sc.gov or consult your solar installer.
South Carolina state law requires all investor-owned utilities with more than 100,000 customers to offer net metering to residential solar customers with systems of 20 kW or smaller. Under net metering, excess electricity your solar panels send to the grid earns you a bill credit that can be applied to future monthly bills. The program is capped at 2% of each utility’s average peak demand over the prior five years. Residents of Bluffton are primarily served by Dominion Energy South Carolina, which offers 1-to-1 net metering credits with an annual true-up each November (remaining credits paid at a lower avoided-cost rate).
Because credit rates at most South Carolina utilities are well below the retail electricity rate, pairing your solar system with a battery storage system can be a smart financial move. Storing excess solar energy for self-consumption during peak hours — rather than exporting it to the grid at a discount — can significantly improve your return on investment. Most modern solar batteries include scheduling features that automate this process after initial setup.
Enrollment in a time-of-use (TOU) rate plan is required by most utilities to participate in net metering. Be sure to contact your specific utility before installation to understand all applicable fees, requirements, and current program availability, as terms can change. Use the South Carolina Energy Office’s Energy Saver Tool at solar.sc.gov to find current net metering program details for your utility.

Leasing Solar Panels
Not every homeowner wants to pay the full cost of a solar system upfront — and that’s where Palmetto’s LightReach program comes in. In Bluffton, the primary utility provider is Dominion Energy South Carolina (DESC), and Palmetto offers a Power Purchase Agreement (PPA) through LightReach for DESC customers.
With a solar PPA, you don’t own the system — Palmetto does. Instead of paying a large upfront cost, you simply pay for the electricity your panels produce at a set rate per kilowatt-hour (kWh). Because solar panels generate more power in Bluffton’s long summer months, your PPA payments will be slightly higher in summer and lower in winter — but your annual savings typically mirror what you’d see with a fixed lease. Palmetto handles all system maintenance and monitoring, so there’s nothing for you to manage. You can learn more about how PPAs compare to buying to see which path fits your situation.
Compared to a cash purchase, a PPA means no large upfront investment, no maintenance responsibilities, and no worry about equipment repairs. Palmetto owns the system, claims the commercial investment tax credit, and passes those savings through to you in the form of a lower per-kWh rate. It’s a straightforward way to start benefiting from solar in Bluffton without the complexity of ownership.
Go solar without the investment
With LightReach, there are no investment costs to recoup, loan payments to manage, or maintenance needs to take on. As soon as your panels are active, your solar savings are too!

Yes, solar makes strong sense in Bluffton. With 5.3 peak sun hours daily and over 215 sunny days per year, Bluffton’s Low Country climate is well-suited for solar production. South Carolina’s 25% state tax credit, property tax exemption, and net metering through Dominion Energy further improve the economics.
For homeowners concerned about upfront costs, Palmetto’s LightReach lease program removes that barrier entirely — you can go solar with no money down and start saving from day one, with payments starting as low as $92/month.
Yes, Bluffton residents have access to net metering through Dominion Energy South Carolina (DESC), the primary utility serving the area. DESC offers 1:1 net metering — meaning excess solar energy you send to the grid offsets your imported energy on a kilowatt-for-hour basis. A Time-of-Use (TOU) rate plan is required, and credits carry forward month to month.
At the annual true-up each November, any remaining unused credits are paid out at a lower avoided-cost rate (approximately 2.8–3.4 cents/kWh), and your account resets to zero. Because excess credits are valued below the retail rate, pairing your solar system with a battery storage system can help maximize your savings by storing energy for self-use rather than exporting it.
Yes, solar panels can increase your home value in Bluffton. Research from Zillow found that homes with solar panels sell for approximately 4.1% more than comparable homes without them. For a $500,000 home in Bluffton, that’s roughly $20,500 in added value.
Bluffton’s strong solar production and South Carolina’s 100% property tax exemption for residential solar systems mean that added value won’t raise your property tax bill — making solar one of the few home improvements that pays you back both monthly and at resale.
