Georgia Solar in 2026: The 10kW NEM Cap & the ROI Cliff

For most Georgia homeowners, yes — but the case is more policy-dependent than sun-dependent, and it hinges on how you size the system. An 8 kW rooftop array costs about $23,200 (2.90/W) and pays back in roughly 13.2 years, with a 25-year ROI near 90%. Georgia has genuinely good sun (5.1 peak hours) and competitive installed costs, but the economics are driven less by the sun than by the policy: there is no statewide net-metering mandate, Georgia Power credits exports at avoided cost (~$0.06/kWh), and the 10 kW system-size threshold creates the sharpest ROI cliff in any top-10 solar state. Get the sizing right and the math works; over-size past the cap and it breaks down.

Georgia Power's residential solar program historically capped favorable export treatment at a 10 kW system size. Systems at or below 10 kW export surplus at a more favorable avoided-cost rate (~$0.06/kWh per the state NemRate of $0.06/kWh); systems above 10 kW see exports credited at a materially lower, deep-avoided-cost rate (~~$0.03–0.04/kWh). The result is an ROI cliff: a 9.9 kW system and a 10.1 kW system can have very different paybacks, because every exported kilowatt-hour from the panels above the threshold is worth roughly half as much. This is the single most important sizing constraint in Georgia solar — and the reason this guide treats the 10 kW threshold as its centerpiece. The practical implication is to size at or below 10 kW unless you have a large genuine daytime load (EV charging, heat pump, all-day AC) to self-consume the surplus that the over-cap panels would otherwise export at a steep discount.

Georgia runs an avoided-cost export model — there is no full-retail net metering and no statewide NEM mandate. Georgia Power credits exported solar at approximately $0.06/kWh (the NemRate of $0.06/kWh recorded in <code class="font-mono text-xs">src/data/nem-policies.json</code>, policyType "Net Billing"), which is well below the ~~$0.13–0.15/kWh you pay to buy power. The crucial nuance is the 10 kW threshold: exports from systems at or below 10 kW earn that ~$0.06/kWh rate, while exports from systems above 10 kW drop to deep avoided cost (~~$0.03–0.04/kWh). So a kilowatt-hour you self-consume is worth roughly two to three times a kilowatt-hour you export under the cap — and even less if you are over the cap. The economics reward sizing to consume, not to export, exactly as in net-billing states like Ohio and post-NEM-3.0 California.

Georgia is a regulated (NOT deregulated) market, so unlike Ohio you do not shop for a generation supplier — but which utility serves your address still matters enormously because each sets its own solar terms. <strong>Georgia Power</strong> is the dominant investor-owned utility (~2.6 million customers) regulated by the Georgia PSC, and its avoided-cost buyback with the 10 kW cap applies to most of the state. Beyond it sit 42 electric membership cooperatives (EMCs) — including GreyStone Power, Cobb EMC, and Jackson EMC — and roughly 50 municipal utilities (Dalton Utilities, Marietta Power, and others). EMCs and municipals set their own solar tariffs outside PSC jurisdiction, and some offer more favorable buyback than Georgia Power's avoided-cost rate. Check your electric bill to confirm your utility before sizing a system, because the export treatment — and whether the 10 kW cap even applies — can differ.

For pure net-metering economics, no — but Georgia's avoided-cost export model makes self-consumption (and thus storage to shift surplus) somewhat more valuable than in full-NEM states, so the case is not as cleanly negative as in Ohio. A battery lets you self-consume surplus that would otherwise export at only ~$0.06/kWh, capturing the full ~~$0.13–0.15/kWh offset instead; that arbitrage is real but usually still marginal against the battery's upfront cost. The stronger justification is <strong>resilience</strong>: Georgia's summer thunderstorm outages and hurricane-season impacts (Matthew, Irma, Helene) combined with extreme heat make keeping air conditioning running during an outage a genuine safety issue, not just a convenience. A grid-tied array without a battery shuts off when the grid drops (anti-islanding), so if outage survival matters to your household, a battery is what makes solar useful when the power is out.

A typical 8 kW rooftop system in Georgia runs about $23,200 (2.90/W) before incentives — competitive with the national average, reflecting a maturing installer base and the presence of domestic manufacturing (Qcells operates a panel factory in Dalton, GA). The 30% federal residential credit (Section 25D) expired December 31, 2025, so owned systems placed in service in 2026 receive $0 federal credit. Leased/PPA systems may still capture Section 48E for projects that began construction before July 4, 2026. Crucially, Georgia offers NO sales-tax exemption (the 4% + local rate applies — budget roughly $930 on an 8 kW purchase) and NO property-tax exemption, so the system will raise your assessed property value and your tax bill. The economic case rests on the competitive $/W, the self-consumption offset, and staying under the 10 kW cap.

Size to consume and stay at or below 10 kW unless you have a large genuine daytime load. Because exports under the cap are worth only ~$0.06/kWh while self-consumption is worth ~~$0.13–0.15/kWh, and exports above the cap collapse to ~~$0.03–0.04/kWh, the optimal Georgia Power system covers your daytime and annual consumption as closely as possible without spilling large surplus past 10 kW. For most homes an 8–9.9 kW array is the sweet spot — large enough to offset the bulk of annual usage, small enough to keep every export in the favorable tier. The one exception is a household with a real daytime sink for the extra power: an EV you charge midday, a heat pump running through summer afternoons, or a work-from-home load. In that case the over-cap panels self-consume at full offset value and the cliff doesn't bite.

No. Georgia has not yet launched a statewide HEAR (Home Energy Rebates) rebate program, and our source-of-truth incentives file records <code class="font-mono text-xs">low_income_program: false</code> for the state. There is no active statewide low-income solar program, no utility rebate per watt, and no SREC market to stack on top of the federal posture. The historic Georgia state solar tax credit exists on paper but is oversubscribed and waitlisted, so in practice it is not available to new applicants. If you are hoping for rebate or low-income assistance, check directly with your utility (Georgia Power or your EMC) for any local or pilot offerings, and do not assume a statewide program is live. The good news is that Georgia's economic case does not depend on HEAR — it rests on competitive installed costs and the self-consumption offset, both of which hold regardless.

After the 2026 expiration of the Section 25D residential credit, the structure carries real federal-tax consequences. A cash purchase or low-interest loan keeps the full long-term savings but receives $0 federal credit — and Georgia's thin incentive menu (no state credit, no sales-tax exemption, no property-tax exemption) means there is little offsetting state value either way. A lease or PPA eliminates upfront cost and can still capture Section 48E (the developer claims the 30% credit and passes value through as lower payments) on projects that began construction before July 4, 2026. In Georgia's regulated market, pay particular attention to how a third-party-owned system is treated under your utility's solar tariff — some EMCs and municipals handle leased systems differently than Georgia Power does. Compare both paths with your actual utility, consumption profile, and the 10 kW cap in mind.

Georgia averages about 5.1 peak sun hours per day statewide — a strong resource, better than Ohio's 4.5 and approaching Florida's 5.8, with productive summers and mild winters. A south-facing 8 kW array tilted near latitude typically produces on the order of $11,466 kWh per year (the state-database figure is 11,466 kWh). Production varies modestly by region: coastal Savannah and south Georgia run slightly higher, while the Atlanta metro and north Georgia mountains run marginally lower. Summer humidity and afternoon thunderstorms clip midday output somewhat, but year-round production is consistently strong — Georgia produces solar in December nearly as well as many northern states do in June. Because export value is low (and drops further past the 10 kW cap), the optimal strategy is to maximize self-consumption — align production with your daytime usage rather than maximizing raw export.

Georgia Power's solar buyback program has an annual true-up, and existing interconnected systems are generally grandfathered at the terms of their interconnection — but because Georgia's export treatment was never full-retail net metering to begin with, "grandfathering" here is less dramatic than in states that transitioned from 1:1 NEM to net billing. The more relevant protection is sizing: a system interconnected at or below 10 kW locks in the favorable avoided-cost tier for its exported surplus, while the over-cap deep-avoided-cost treatment applies to systems sized above the threshold at interconnection. The watch-item is future PSC proceedings: Georgia Power periodically revisits its avoided-cost rate in regulatory filings, and the buyback rate can move with fuel and capacity costs. Interconnecting sooner rather than later locks in the current ~$0.06/kWh export treatment under the cap.

Georgia's tax posture is thin on the incentive side. There is NO property-tax exemption — installing solar will raise your assessed property value and your annual property-tax bill, unlike in states such as Florida or Ohio that exempt the added value. There is NO sales-tax exemption — the 4% + local state plus local rate applies to the equipment purchase, adding roughly $930 to an 8 kW system. There is no active state solar income-tax credit; a historic credit exists on the books but is oversubscribed and waitlisted, so it is effectively unavailable to new applicants. There is no SREC market and no low-income program. The contrast with neighboring Florida — which has no income tax, a 6% sales-tax exemption, and a 100% property-tax exemption — is stark. Georgia's solar case rests on competitive installed costs and the self-consumption offset, not on tax breaks.
