Solar panel installation in Trenton, SC

Most Trenton addresses are served by Aiken Electric Cooperative, whose territory covers Edgefield County among others. Cooperatives set their own export credit rather than crediting at retail, so we confirm yours and what it currently pays before designing.

The one whose licence checks out with SC LLR (the Residential Builders Commission and contractor licensing), whose quote names Aiken Electric Cooperative and states about 13,780 kWh a year for 9.5 kW, and who services what it installs. Ours does all three, with a lifetime full-system warranty.

At the $2.59 per watt benchmark, a 6 kW system is about $15,540 installed and a 9.5 kW system about $24,605. South Carolina’s 25% state credit brings those to about $11,655 and $18,454, claimed at up to $3,500 a year. In Trenton that 9.5 kW system makes about 13,780 kWh a year unshaded; your quote depends on roof, shade and usage.

Aiken Electric Cooperative sets its own export credit, which sits outside South Carolina's net metering chapter, so we confirm the current figure per account before modelling anything. Aiken Electric Cooperative households paid about 15.5¢ per kWh on average in 2024, so every kWh you use at home is worth more than one you export, and we size to your usage rather than to fill the roof.

Not for homeowners who buy: it ended December 31, 2025. South Carolina’s 25% state credit still applies to systems you own, capped at $3,500 a year with a 10-year carry-forward.

Qualifying residential systems of 20 kW or less are exempt from South Carolina property tax. Check with the Edgefield County assessor.

64% of Trenton homes are owner-occupied, and for owners the choice is real. Buying, with cash or a loan, means you own the system, can claim South Carolina’s 25% credit, and add an asset to the house. With a lease or power purchase agreement the provider owns the panels, so you cannot claim the state credit for them, and a buyer of your home has to take over the agreement.

Formal HOAs are uncommon around Trenton, so placement is usually an engineering question rather than an approval one. Where covenants apply we prepare the packet as part of the install.

A building permit and a separate electrical permit, issued by Edgefield County Building and Planning rather than Aiken County; A zoning review as well for any ground-mounted array, which is common on parcels this size; An additional electrical permit where battery storage is included; Interconnection approval from whichever utility serves your meter. We pull every one through Edgefield County and book the inspections.

Your roof needs replacing within about five years and there is no suitable ground-mount location. Your power bill is under roughly $90 a month. You are likely to move within five years.
