What instantaneous netting actually means
Georgia Power residential solar runs on RNR-Instantaneous Netting. Generation is measured against household consumption at the moment it occurs rather than being totalled across a billing period.
When your home is drawing power and your panels are producing, the panels serve the load and you simply do not buy that electricity. That kilowatt hour is worth the full retail rate, which for Georgia Power residential customers has been in the region of 14 to 15 cents.
When your panels produce more than the house is drawing at that instant, the excess is exported and credited at the annual Solar Avoided Cost Rate, 3.2188 cents per kWh for 2026, with a 4 cent per kWh adder approved in the 2022 rate case.
Nothing banks. There is no kilowatt hour credit accumulating through summer to be spent in winter, because the accounting happens continuously rather than at a settlement date. A sunny Tuesday afternoon with an empty house is a small credit, not stored value.
The gap between using and exporting
Put the two numbers side by side and the design brief writes itself. A kilowatt hour you consume is worth the retail rate. A kilowatt hour you export is worth a fraction of it.
In a retail-rate net metering state those two are the same, which is why national advice treats them interchangeably and why so much of it misleads a Georgia reader.
This is the reason to be sceptical of an Atlanta quote whose savings figure is derived from annual production. Annual production tells you what the system makes; it does not tell you what share of it your household actually uses at the moment of generation.
Ask for the savings model broken into two lines: value from self-consumed generation at the retail rate, and value from exported generation at the avoided cost rate. If a quote cannot produce that split, it has not modelled Georgia correctly.
What that means practically
Self-consumption becomes the lever you actually control. Running the dishwasher, the laundry and the pool pump in the middle of the day converts low-value exports into full-value offsets without spending anything.
A battery does the same thing on a larger scale, storing midday production for evening use. That is why storage carries more weight in Georgia than the national conversation suggests: it is not about outage resilience alone, it is about tariff arbitrage that genuinely works here.
An electric vehicle charged during the day rather than overnight is one of the most effective changes available, because it is a large, shiftable load.
And the system should be sized to your daytime consumption pattern rather than to your annual total. Residential systems are capped at 10 kW AC in any case, but the binding constraint for most Atlanta homes is what the house can absorb rather than what the roof can hold.
Costing it out against a capped programme
The 30 percent federal Residential Clean Energy Credit under Section 25D expired for property placed in service after December 31, 2025, so a cash or loan purchase in Atlanta receives no federal tax credit. Georgia has no state solar tax credit to fall back on either.
Section 48E, the commercial credit, survives at 30 percent for third-party owners under leases and power purchase agreements. Ask what a provider claims and what portion reaches you in the rate, and confirm with a tax advisor.
What exists is the tariff itself: full retail value for self-consumed generation, avoided-cost value for exports, under a programme that is capped and first come, first served.
Ask any installer to rebuild the projection with self-consumption and export shown as separate lines, and to state what share of generation the model assumes you consume directly. That assumption is the quote.
