NV Energy pays you 9.8¢ for each kWh of solar you export, and charges about 13¢ for each kWh you buy back. Putting that surplus into your car instead of the grid keeps the difference.
NV Energy nets monthly and credits excess exports at 75% of retail (Tier 4, the tier for every new signup), locked for 20 years. The gap is narrower than in California, but every exported kWh still earns less than it costs to buy back.
An 8 kW system with 20 kWh/day of July surplus, and an EV driven 40 miles a day at 3.5 mi/kWh (about 11.4 kWh/day). The car can absorb 11.4 of the 20 kWh, so 343 kWh a month goes to the car instead of the grid.
| Where the 343 kWh goes | Rate | Per month |
|---|---|---|
| Exported to NV Energy | 9.8¢/kWh credit | $33.43 |
| Charged into your EV (grid imports avoided) | 13¢/kWh avoided | $44.57 |
| Difference from charging on solar | $11.14 |

Signed up in an earlier tier? Tiers 1–3 credit a higher share of retail, and pre-2016 legacy net metering credits 100% — so your gap is smaller than the one shown here.
Live SolarEdge production, plus grid and battery when you have a meter.
Enphase production, plus grid and IQ Battery when your system meters them.
Solar-only charging for a Tesla on any charger, including the Wall Connector.
The calculator starts from NV Energy's rates for your zip and plan, then lets you adjust your system size and driving.

Works to utilize my solar to charge my car! I have it set up so I don't draw from the grid to charge my car (free fuel!)
