Palmetto Reviews

The consultation was top notch the whole way, even after the install. At times companies will treat you like royalty before you put down the signature, but then drop off afterwards. But Palmetto Solar was professional along the whole way. I already recommended them to neighbors.

Summerville Electricity Prices

If you live in Summerville, you’ve likely noticed your electricity bills creeping higher year after year. Here’s what’s driving that trend.

South Carolina electricity prices rose about 9.3% from 2021 to 2024, climbing from 12.9 to 14.1 cents per kWh. While that stays below the national average, rates keep rising steadily each year.

Solar helps address these rising costs by generating power from Summerville’s abundant Lowcountry sunshine. Instead of relying fully on the grid, your home can produce some of the energy it uses each day.

South Carolina Solar Incentives

Summerville homeowners can tap into several solar incentives in South Carolina designed to help offset the cost of a solar installation.

South Carolina’s Solar Energy Tax Credit (Form TC-38) allows homeowners in Summerville to claim 25% of their total solar installation cost against their state income tax liability. The credit is capped at $3,500 per year, with 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 fully available for 2026 installations and beyond.

If you cannot use the full credit in a single tax year, any unused portion carries forward to the next tax year for up to 10 years. This is especially helpful for homeowners whose annual state tax bill is lower than $3,500. Note that the credit is non-refundable — it can reduce your tax liability to zero, but you will not receive a refund check for any excess amount.

To claim the credit, file Form TC-38 (SCH.TC-38) along with your South Carolina state income tax return. You will need supporting documentation such as your solar system design, permits, and receipts showing total installation costs. The credit applies to solar PV panels and solar water heaters.

Leasing Solar Panels

In Summerville, your solar financing option depends on your utility. If your home is served by Dominion Energy South Carolina, a Power Purchase Agreement (PPA) through LightReach may be available. With a PPA, you simply pay a set price for the solar energy your panels produce—no large upfront cost required.

Compared to buying your system with cash, a PPA lets you start saving right away. Because bills follow production, you’ll typically pay more in sunny summer months and less in winter, evening out over the year.

Palmetto also owns and maintains the system, so repairs and upkeep aren’t your responsibility. It’s a simple, low-commitment way to enjoy clean energy in Summerville.
