Install solar panels and you’ll probably produce more electricity than your home needs during sunny periods, especially in the middle of the day when no one’s home and the panels are running at full output. What happens to that excess power, and what do you get paid for it? That’s where solar buyback programs come in.

The answer varies dramatically depending on where you live and who your utility company is. In some places, you get the full retail rate for every unit you export. In others, you get a fraction of what you pay. Understanding the difference matters a lot for calculating how much solar will actually save you.

What Is a Solar Buyback Program?

A solar buyback program is an arrangement where your utility company or electricity provider credits you for excess solar electricity you export to the grid. When your panels produce more than your home is consuming at a given moment, that surplus flows into the local power grid. Rather than losing that energy, you receive compensation for it, either as a bill credit or, less commonly, a direct cash payment.

Buyback programs go by different names in different contexts. In regulated utility markets, the most common form is called net metering. In deregulated energy markets, particularly Texas, they’re called solar buyback plans and are offered by specific electricity providers as distinct rate plans. The mechanics differ, but the basic concept is the same: you get value for what you export.

Net Metering vs. Solar Buyback Plans

Net metering is a state-mandated policy that credits your bill for exported electricity at the same rate you pay to buy electricity from the grid. If you pay $0.15 per kWh for grid power, you receive $0.15 credit per kWh you export. It’s a one-for-one exchange.

Solar buyback plans, most common in deregulated states like Texas, operate differently. You’re charged the retail rate for grid electricity you consume, and you receive a separate, usually lower rate for electricity you export. The buyback rate might be $0.06 per kWh when you’re paying $0.12 for consumption. The gap between what you pay and what you receive is the spread that the electricity provider profits from.

In states with full net metering, the math is simpler and more favorable for homeowners. Oversizing your system slightly to export more during peak sun hours makes sense because every excess kWh earns a full retail credit. In deregulated buyback markets, the calculation is different: you want to maximize self-consumption and size the system to minimize excess rather than maximize export, because the buyback rate doesn’t compensate you equally for what you export.

How Solar Buyback Credits Work on Your Bill

In a net metering state, your utility tracks exports and consumption on a monthly basis. If you export 500 kWh in a month and consume 800 kWh, you’re billed for the net difference: 300 kWh. The exported 500 kWh directly offsets 500 kWh of your consumption at the retail rate.

Annual true-up policies handle situations where you’ve built up excess credits over summer months. Some utilities pay out excess credits at the end of the year, either at retail rate or at a reduced “avoided cost” rate. Others roll credits forward indefinitely. Some only allow carry-forward for 12 months before excess expires. Check your specific utility’s policy on annual true-up, as it affects whether it makes sense to oversize your system.

In a deregulated buyback plan like those in Texas, the billing is straightforward: you receive a monthly bill showing what you consumed at your plan’s retail rate minus the credit for what you exported at the buyback rate. The net is what you owe or, occasionally, receive as a small check.

Solar Buyback in Texas: The Deregulated Market

Texas doesn’t have a statewide net metering law. Most Texas utilities don’t offer net metering at all. Instead, solar homeowners in the competitive retail electricity market shop for specific solar buyback plans from Retail Electric Providers (REPs) who offer to purchase their excess solar production.

Buyback rates in Texas vary significantly between providers and plan types. Some offer $0.03 to $0.07 per kWh for exported solar. Others have structured “1-to-1” or “1-to-2” plans that credit at higher rates during specific time periods. Some plans offer credits only at certain times of day, rewarding peak-hour export more than off-peak.

Finding the best Texas solar buyback plan requires comparing not just the buyback rate but the full plan structure: what you pay per kWh for consumption, when buyback rates apply, whether there are minimum usage fees, and how credits roll over. Several comparison tools and sites aggregate Texas solar plans to help homeowners evaluate options.

Which States Have the Best Solar Buyback Policies?

States with full retail-rate net metering include Massachusetts, New Jersey, Illinois, and most New England states. These are among the best markets for solar economics because every excess kWh is worth exactly as much as grid electricity you’d otherwise buy.

California shifted from NEM 2.0 to NEM 3.0 in April 2023, dramatically reducing the value of exported solar. Under NEM 3.0, export credits dropped by roughly 75% compared to NEM 2.0. This hasn’t made solar uneconomical in California but has changed the optimal system design: smaller systems focused on self-consumption, often paired with a battery to shift solar production into evening peak hours, now make more sense than oversized systems that export heavily during midday.

Florida, Georgia, and other southeastern states vary by utility but generally offer some form of net metering, though compensation structures differ. Hawaii has moved away from traditional net metering entirely, with exported solar compensated at low grid-supply rates, making self-consumption and storage the primary strategy for Hawaiian solar homeowners.

How Buyback Rate Changes Affect System Design

The buyback rate your utility offers should directly influence how your solar system is sized and whether adding battery storage makes sense. In high-buyback-rate environments (full net metering), bigger is often better: generating more than you consume means more valuable credits. In low-buyback-rate environments, battery storage becomes more attractive because storing your excess solar and using it yourself at night is worth more than exporting it at a low buyback rate.

This is why state-specific policy knowledge matters when designing a solar system. An installer quoting you in California shouldn’t be designing the same system they’d design in Massachusetts. If they’re not factoring your local buyback rate into their production and savings estimates, that’s a red flag.

Frequently Asked Questions

What is a solar buyback rate?

A solar buyback rate is the price per kWh you receive from your utility or electricity provider for excess solar electricity you export to the grid. It can range from the full retail rate you pay for electricity (in net metering states) to a much lower wholesale or avoided-cost rate (in deregulated markets or states with limited buyback policies).

What is the difference between net metering and solar buyback?

Net metering is a state policy that credits exported solar at the full retail electricity rate, creating a 1-to-1 exchange. Solar buyback plans (common in Texas and other deregulated markets) are market-based arrangements where your electricity provider sets a buyback rate, typically lower than the retail rate you pay for consumption. Net metering is generally more favorable for homeowners.

How do I get paid for excess solar power?

In most cases, excess solar production earns a credit on your electricity bill rather than a cash payment. The credit reduces what you owe. If your credits exceed your charges for the month, most utilities carry the credit forward to future bills. Direct cash payments for excess solar are less common and usually only available through specific buyback plan structures.

What states have the best solar buyback programs?

Massachusetts, New Jersey, Illinois, and most New England states offer full retail-rate net metering, making them among the best states for solar economics. Arizona, Colorado, and Maryland also have favorable policies. California has reduced buyback rates under NEM 3.0 but still offers significant solar incentives. States without net metering mandates, including some southeastern states, vary widely by individual utility.

Does Texas have solar buyback programs?

Texas doesn’t have statewide net metering. Instead, homeowners in the deregulated electricity market shop for solar buyback plans from Retail Electric Providers. Rates and terms vary widely between providers. Some plans offer $0.03 to $0.07 per kWh for exports; others have structured plans with higher rates at peak times. Comparing plans specifically for their buyback terms is essential for Texas solar buyers.

What happens if I produce more solar than I use in a month?

Your excess production earns credits. In net metering states, those credits carry forward to offset future months’ bills. Many utilities do an annual true-up where unused credits may be paid out at a lower rate or expire. In deregulated buyback plans, excess credits are typically applied to the following month’s bill. Check your specific utility’s policy on credit rollover and annual settlement.

Should I oversize my solar system to maximize buyback credits?

Only if your buyback rate is at or near retail. In full net metering states, oversizing to export more can make sense because every exported kWh earns a full retail credit. In states with reduced buyback rates or California’s NEM 3.0 structure, self-consumption is worth more than export, so sizing to consumption (with battery storage for evening use) is smarter than sizing to maximize export.

Will solar buyback rates change in the future?

They already have in several states. California reduced buyback rates significantly in 2023. Other states are reviewing their net metering policies as solar penetration increases. This is a real long-term consideration for solar buyers: the buyback rate that makes your system look attractive today could be reduced during your 25-year ownership period. Battery storage hedges against this risk by enabling more self-consumption and less grid dependence.

Summing Up

Solar buyback programs and net metering policies are a major factor in solar economics, second only to your local electricity rate. Full retail-rate net metering makes solar significantly more valuable and allows for larger systems that fully offset annual consumption. Reduced buyback rates shift the optimal strategy toward self-consumption and battery storage. Knowing what your specific utility offers before sizing and purchasing a solar system is essential, and it’s something your installer should factor into their production estimates and payback period calculations.
