Cary, NC
Licensed contractors serving Cary and the surrounding Triangle area. Duke Energy Progress territory, Town of Cary permits.
Cary has one of the highest EV adoption rates in the Triangle, driven by its concentration of tech and pharma workers. SAS Institute, Fidelity, and the Research Triangle Park commuter corridor have all contributed to a city where EVs are a practical daily choice, not an experiment. A Level 2 charger on a dedicated 240V circuit is the standard solution: 20 to 30 miles of range added per hour, a near-empty battery ready by morning.
Most Cary homes built after 1990 have 200-amp service with room for a new 40 or 50-amp circuit. The work typically takes two to four hours. The Town of Cary issues its own electrical permits through its residential permits portal — your electrician pulls it before starting and schedules the inspection after. Duke Energy Progress offers the Charger Prep Credit, which covers up to $1,133 toward the electrical prep work.
Cary's newer residential developments tend to have unobstructed south-facing roof sections that work well for solar. Homes in established neighborhoods like Preston, MacGregor Downs, and Lochmere have mature tree canopy in places — a site assessment will confirm whether shading is a factor on your specific roof.
Cary is Duke Energy Progress territory. New solar customers should compare the current Duke Energy net metering riders and avoid assuming old full-retail export credits. The best financial outcome usually depends on using more solar generation directly and confirming any PowerPair eligibility before relying on the incentive.
If your community has an HOA, NC law (NCGS § 22B-20) protects your right to install solar despite HOA restrictions. HOAs can require approval and set reasonable aesthetic standards, but they can't prohibit installation outright. The NC HOA solar approval guide explains what the statute says and how to navigate the process.
A home battery stores energy — from your solar panels during the day, or from the grid during off-peak hours — and discharges it when you need it most. For Cary homeowners on a Duke Energy Progress time-of-use plan, that means avoiding peak-rate charges in the evening. For everyone, it means a few days of essential circuits running when the grid goes down.
PowerPair is only available when solar and battery are installed together for the first time and the project meets Duke Energy's current program rules. Cary is Duke Energy Progress territory, and Progress capacity is exhausted as of June 2026, so only include PowerPair if Duke confirms an existing reservation.
Most Cary homes built after 1990 already have 200-amp service. Adding a Level 2 EV charger or a typical residential solar system doesn't require a panel upgrade for most homeowners. The question is whether your panel has available breaker slots for the new circuit, not just what the service size says on paper.
Older sections of Cary — particularly homes built in the 1970s and early 1980s near downtown — are more likely to have 100-amp service. If you're adding an EV charger, solar system, and whole-home heat pump in the same timeframe, a load calculation makes sense even if you're on 200-amp service. Duke Energy Progress disconnects service at the meter before the work begins and reconnects after — your electrician coordinates this. The Town of Cary requires an electrical permit and final inspection through its permits portal.
