If you have solar panels, a solar buyback plan lets you earn money for electricity you generate but don't use. Here's how it works and whether it's worth it for your home.
What Is a Solar Buyback Plan?
A solar buyback plan is an electricity plan that credits your account when your solar panels produce more electricity than you consume. The excess power flows back to the grid, and your provider reimburses you—usually at a reduced rate.
Simple Example
- You generate 800 kWh from solar panels this month
- You use 600 kWh in your home
- Excess: 200 kWh flows to the grid
- You earn credit for those 200 kWh (usually at a lower buyback rate)
How Much Does Solar Buyback Pay?
Buyback rates vary, but here's the typical structure:
- Standard electricity rate: 12¢/kWh (what you pay to buy from the grid)
- Solar buyback rate: 4–8¢/kWh (what you earn for solar excess)
You don't earn the full retail rate for solar—the discount reflects transmission losses and market value. But every credit helps offset your bill.
Real Savings Example
Scenario: You have 5 kW solar panels and an Ambit solar buyback plan.
- Monthly generation: 600 kWh
- Monthly usage: 400 kWh
- Excess to grid: 200 kWh
- Buyback rate: 6¢/kWh
- Monthly credit: 200 × 0.06 = $12
- Annual savings: ~$144
Is a Solar Buyback Plan Worth It?
When It Makes Sense
- ✅ You have south-facing roof space with good sun exposure
- ✅ Your home's electricity usage is moderate (500–1500 kWh/month)
- ✅ You're not moving in the next 5+ years
- ✅ Your local utility allows net metering or grid-tie solar
When It Might Not Be Worth It
- ❌ You live in a shaded area or have a north-facing roof
- ❌ Your usage is very high (you consume all your solar output)
- ❌ Your utility charges high interconnection fees
- ❌ You're planning to move soon
Key Insight
Solar payback periods typically range from 5–10 years depending on system size, installation costs, and your buyback rate. After that, your electricity is nearly free.
Tips for Maximizing Solar Savings
- Choose a plan with a higher buyback rate: Compare plans and pick one with the best solar credits.
- Pair solar with energy storage: A battery system lets you store excess for evening use instead of selling it cheap.
- Reduce daytime usage: Run heavy loads (dishwasher, laundry, EV charging) during peak solar hours.
- Monitor your production: Most systems have apps showing real-time generation. Use this to shift usage.
Check Solar Buyback Plans
If you have solar panels, compare buyback rates available in your area. Higher rates mean faster payback.

Solar buyback plans are a smart way to offset your electricity costs if you have solar panels and live in a deregulated Texas area. The credits may be modest (4–8¢/kWh), but they add up—and combined with the federal tax credit and state incentives, solar can pay for itself in 5–7 years.
