How to Maximize Savings with Georgia Power's Solar Program

Georgia Power's current solar program, often called net metering, is a key piece of the puzzle. When your panels overproduce during the day, you send that power to the grid. Georgia Power buys it from you at an 'avoided cost' rate—around 10¢ per kilowatt-hour. Since you pay about 13¢/kWh to buy power, this isn't an even trade. The smartest strategy is to use the power you generate yourself. This is where a battery becomes valuable; it stores your excess solar power so you can use it at night instead of selling it cheap and buying it back expensive.

Projected Savings

Your Potential Monthly & Lifetime Savings

By generating your own clean power, a typical Johns Creek household can expect to reduce their annual electricity costs by about $735. While that's a great start, the real value is long-term. Over 25 years, that could translate into more than $18,000 in savings, all while increasing your home's resale value in a competitive real estate market.

Local Questions Answered

Do I need approval from my HOA in Johns Creek to install solar panels?
Yes, you will likely need to submit your plans to your Homeowners Association for approval. However, Georgia law limits an HOA's ability to prohibit solar installations, though they may have reasonable restrictions on placement and aesthetics.
How much does a battery add to the payback period?
A battery significantly increases the upfront cost, extending the purely financial payback period from around 11 years to over 22 years. Homeowners choose batteries less for rapid ROI and more for the invaluable security of having backup power during outages.
Will solar panels increase my Johns Creek property value?
Studies from Zillow and the National Renewable Energy Laboratory (NREL) have consistently shown that homes with solar panel systems sell faster and for a premium compared to similar homes without them.
