Cost and savings sections below are sized to a typical system for this city’s average utility bill (~8.3 kW modeled). Typical monthly bill here: $127.62.

At this bill level, modeled system sizes are often in the mid-to-high single-digit kW range. Use the calculator below to match your actual usage.

For homeowners in Snellville, the math for rooftop solar has changed. Electricity from Walton EMC costs around 14.2 cents per kWh, but the credit you receive for sending surplus solar power back to the grid is significantly lower. This shift makes using the energy you generate your top priority. The question is no longer just about how much power your panels can produce, but how much of that power you can use yourself to offset your Gwinnett County utility bills.

Benchmark Cost Analysis

Solar & Battery Costs in Snellville (2026)

Here are the estimated costs for a professionally installed system sized for a typical home in the Snellville area:

  • Solar Panels Only (8.3 kW): The estimated gross cost is around $20,335. This system is designed to cover a significant portion of a home's electricity usage during daylight hours.
  • Solar Panels + Battery (8.3 kW system with 10 kWh battery): The estimated gross cost is $35,335. The battery stores excess solar energy for use in the evening or during a power outage, maximizing self-consumption.

These figures are pre-incentive estimates for 2026 and can vary based on your specific roof, equipment choices, and installation complexity.

Incentives & Tax Credits

Georgia's Solar Incentives for 2026

While the 30% federal tax credit for homeowners is no longer the primary incentive for systems installed in 2026, Georgia residents still have access to valuable financial benefits:

  • Property Tax Exemption: This is the most significant incentive in Georgia. Installing a solar energy system will not increase the assessed value of your home for property tax purposes. This saves you money every year on your Gwinnett County property tax bill.
  • No State Sales Tax: Solar energy equipment is exempt from state sales tax in Georgia, reducing the upfront cost of your system.

These state-level policies help improve the long-term financial return of a solar investment, even without a federal income tax credit.

Understanding Export Rates with Walton EMC

Georgia's utilities, including Walton EMC, do not offer traditional 1-for-1 net metering. Instead, they use an 'avoided cost' or similar structure for crediting homeowners for excess solar generation. You purchase electricity at the full retail rate of about 14.2 cents/kWh, but any surplus power you export to the grid is only credited at around 6.5 cents/kWh. This discrepancy is why maximizing self-consumption with a battery is now the recommended strategy for achieving the best financial outcome with solar.

Projected Savings

How a Battery Impacts Your Annual Savings

Because exported solar power is worth less than retail electricity, storing it for your own use is key. A battery helps you avoid selling your solar energy to Walton EMC for a low price and then buying expensive grid power back just a few hours later.

  • With a solar-only system, a Snellville household could see an estimated annual savings of $1,157.
  • By adding a 10 kWh battery, those savings increase to approximately $1,291 per year. The battery helps you use more of your own clean energy, which is more valuable than the export credit.

Beyond the immediate bill reduction, an owned solar system can also be an attractive feature for potential home buyers. It also provides a hedge against future utility rate increases—if grid electricity becomes more expensive over time, your rooftop generation becomes even more valuable.

Local Questions Answered

Why is a battery so strongly recommended for solar in Snellville?
Because the credit you get from Walton EMC for exported solar power is less than half the price you pay for electricity from the grid. A battery lets you store your valuable solar energy to use at night, instead of selling it for a low price. This maximizes your savings and gives you backup power during outages.
What happens if I install solar panels without a battery?
A solar-only system will still save you significant money by producing energy you use during the day, directly offsetting your utility bill. However, any excess power your system generates will be sold to the grid at the lower avoided-cost rate, reducing your total potential savings compared to a solar-plus-battery system.
Are there any Georgia state tax credits for solar in 2026?
No, as of early 2026, Georgia does not offer a state income tax credit for residential solar installations. The primary state-level incentives are the property tax exemption and the sales tax exemption on solar equipment.
