An honest answer · Hanahan, SC
Is solar worth it in Hanahan, SC?
The honest answer · as of July 2026
For some Hanahan homes yes, for others genuinely no, and anyone who answers without seeing your roof and your bill is selling rather than advising. It turns on four things: what your utility credits exports at, how much production you can use on site, your roof's condition and shading, and how long you will stay. Solar in Hanahan became a harder case in 2026, and we would rather explain why than talk around it.
Local verdict
The honest read on Hanahan
Hanahan is worth a look precisely because it is close to our Daniel Island office, so a site visit costs you nothing and settles the two open questions quickly: which utility bills you, and how much canopy sits over your best roof plane. Neither is reliably answerable from a satellite image, and both change the answer materially.
The utility question is the sharper of the two here. Berkeley Electric Cooperative serves many Hanahan meters and Dominion Energy South Carolina serves others, and their export terms differ. Because a good share of what a system earns depends on that rate, two identical houses on the same street can produce genuinely different verdicts. Anyone giving you a Hanahan-wide answer has skipped the step that matters.
The favourable factor is consumption. Bills in the established housing stock are often high relative to floor area, because older envelopes and older air conditioning work harder for the same comfort. High consumption during daylight hours is exactly what current export rates reward, so where the roof and the canopy cooperate, the case here is frequently better than the size of the house would suggest.
Written for Hanahan specifically. Your own roof, bill and meter still decide the answer, which is what the free assessment settles.
Start with what changed
Two things happened in 2026, and both hurt
Dominion Energy South Carolina closed one-for-one net metering to new residential systems. Under Solar Choice, exported power now credits at roughly 2.8–4.1¢ per kWh instead of at the retail rate, with a rider of about $14 a month and a November true-up. The federal 30% credit expired at the same time, for systems placed in service on or after January 1, 2026, and South Carolina's capped 25% credit does not fill the hole. Our guide to the 2026 credit position sets out the national picture.
Both changes push the same way, so payback in Hanahan is longer than the figures still sitting on national comparison sites, which were calculated under the old rules.
None of that means solar stopped working here. It means the margin for error narrowed, and right-sizing and self-consumption now matter far more than they did. A well-designed system for the right home still makes sense. An oversized one sold on old assumptions does not.
The decision framework
Four variables decide it. Panel brand is not one of them.
- 01
What your utility credits exports at
The variable most people never consider, and the one that moved most. Dominion Energy South Carolina credits exported power at roughly 2.8–4.1¢ per kWh under Solar Choice, against about 14.4¢ per kWh. Every kilowatt-hour you export instead of using is worth roughly a quarter as much. This single fact reshapes the answer for Hanahan.
- 02
How much production you can actually use
Follows directly from the first. A household home during the day, running air conditioning, a pool pump or a home office, self-consumes most of what it generates. A household out from eight until six exports most of it. Same roof, same system, materially different return.
- 03
Your roof: condition, orientation, shade
Roof age sets whether you should do this now or after a replacement. Orientation and pitch set how much you generate. Shade sets the ceiling: established lots carry mature canopy; the newer pockets are more open. Worth measuring rather than guessing from a satellite image.
- 04
How long you will stay
Payback in this market runs well over a decade, so a five-year horizon almost never reaches it. An owned system may support resale value, which softens the maths, but if you are likely to move soon that is a real argument against.
Notice what is absent: panel brand, inverter brand, and the size of the system. Those follow from the four above rather than driving the decision.
Two lists
Who solar suits in Hanahan, and who it doesn't
Most installers publish the first list. We publish both, because the second one is what you actually need if you are trying to decide.
Solar usually makes sense for your Hanahan home if
- Your power bill runs above roughly $150 a month, so there is real spend to offset.
- Your roof is sound with 10+ years left, or you are replacing it anyway and can do both as one project.
- You have unshaded south, west or east-facing roof area with reasonable pitch.
- A meaningful share of your usage is during daylight: someone home in the day, a pool pump, a home office, an EV on the drive.
- You plan to stay 10 years or more.
- You have South Carolina tax liability to absorb the 25% credit, since it is non-refundable and capped annually.
Solar is probably not right for you if
- Your roof needs replacing within about five years.
- Your power bill is under roughly $90 a month.
- Mature canopy shades your best roof planes.
- You are likely to move within five years.
- Your meter turns out to be on a co-op with materially worse export terms, which we will tell you plainly.
- You have little or no South Carolina tax liability, so the 25% state credit cannot be fully used. It is non-refundable and capped annually.
- You are being sold on a 30% federal credit. That quote is wrong, and it is a reason to walk away from that company rather than from solar.
If two or more of these describe your situation, we will tell you so at the assessment and we will not design a system to argue you past them.
Getting to a real answer
What a free assessment actually settles
The four variables are answerable for your specific address. That is the whole job.
- Your actual utility and rateAround Hanahan, Berkeley Electric Cooperative serves many addresses here, and the terms differ. This is not guesswork we can do from a map.
- Your real usage shapeFrom your usage history, not a square-footage estimate, so we can see what you would self-consume.
- Roof condition and remaining lifeIncluding the awkward answer if the roof should come first.
- Shade, measuredNot judged from a satellite photo in February.
- A right-sized designOur combined experience averages about 9.5 kW, against the 14.51 kW national calculators assume for this market.
- An honest recommendation, including noThere is no obligation and no pressure. If we say wait, we mean wait.
Resale
Does it add to your home's value?
Research, most often Lawrence Berkeley National Laboratory's, has generally found that homes with owned solar sell for more than comparable homes without it. The effect depends on your market and your system, so nobody can give you a figure for your address, and leased systems behave differently. Selling a home with solar covers the transfer mechanics.
Treat resale as a reasonable secondary benefit rather than a primary reason to buy. If the four variables above do not work, a possible resale premium will not rescue the decision.
Hanahan worth-it FAQ
The questions people actually ask us
Is solar worth it in Hanahan, SC in 2026?
For some homes here, yes. For others, honestly no. It comes down to four things: what your utility credits exported power at, how much of your production you can use on site, your roof's condition and shading, and how long you plan to stay. Hanahan homes with a sound unshaded roof, a bill above roughly $150 a month and significant daytime usage tend to make sense. Homes with heavy shade, a low bill, an ageing roof or a likely move within five years usually do not.
Did solar get worse in Hanahan after 2025?
Yes, and pretending otherwise would be dishonest. Two changes landed at once: the 30% federal credit expired for systems placed in service on or after January 1, 2026, and Dominion Energy South Carolina closed one-for-one net metering to new residential systems. Payback periods here are meaningfully longer than the figures still published on aggregator sites, which were calculated before both changes.
Does solar increase home value in Hanahan?
Research has generally found that homes with owned solar sell for more than comparable homes without it, though the effect depends on your market and your system, and leased systems behave differently from owned ones. We are not going to put a percentage on your house. It is a reasonable secondary consideration, not a reason to buy on its own.
What electricity bill makes solar worth considering in Hanahan?
As a rough screen, a bill under about $90 a month rarely justifies a system, because there is not enough spend to offset. Above roughly $150 a month with meaningful daytime usage, it is usually worth running the numbers properly. Between those, it depends heavily on your roof and your usage pattern.
Is solar worth it if I am not home during the day?
It is a weaker case than it used to be. Under Solar Choice, exports credit at roughly 2.8–4.1¢ per kWh against about 14.4¢ per kWh, so production you cannot use is worth a fraction of production you can. Shifting flexible loads into daylight, or adding storage, closes that gap. Without either, expect your bill to move less than you hoped.
Will you tell me if solar is not right for my home?
Yes. That is the point of a free, no-pressure assessment, and it is why we publish the poor-fit list on this page rather than hiding it. We would rather lose a sale than install a system that does not serve you, because the second kind of customer tells everyone.
