Vermont Solar Overview
Vermont surprises people. Everyone thinks cloudy New England state and assumes solar does not work. But Vermont has some of the best solar policies in the country. Group net metering is a game-changer—I have seen farms and businesses use one big installation to cover multiple meters across different locations. Plus electricity rates are high enough that even with fewer sun hours, the economics work out. Policy matters as much as sunshine, and Vermont proves it.
Vermont may not have Arizona sunshine, but it compensates with exceptional solar policies. The state has embraced renewable energy with net metering rules that rival anywhere in the country. Add in higher-than-average electricity rates and strong community support for clean energy, and Vermont becomes a surprisingly good solar market.
Why Vermont Works for Solar

- Group net metering: Share credits across multiple meters
- Higher electricity rates: ~$0.20/kWh boosts savings
- State tax credit: Additional incentive beyond federal
- Strong community solar: Options for renters and shaded properties
- Property tax exemption: Solar value excluded from assessment

Solar Costs
| System Size | Gross Cost | Annual Production |
|---|---|---|
| 6 kW | $18,000-$20,400 | 6,600-7,200 kWh |
| 8 kW | $24,000-$27,200 | 8,800-9,600 kWh |
| 10 kW | $30,000-$34,000 | 11,000-12,000 kWh |
Payback Considerations
- Electricity rate: ~$0.20/kWh makes savings meaningful
- Net metering value: Full retail credit for exports
- State incentives: Tax credit reduces upfront cost
- Typical payback: 7-10 years depending on usage
Climate Considerations
Vermont Weather and Solar
- Peak sun hours: 3.8-4.2 hours average
- Cloud cover: More overcast days than Southwest
- Snow: Panels typically self-clear; steep roofs help
- Cold temps: Actually boost panel efficiency
- Seasonal variation: Strong summer production, lower winter
Production Estimates
- Annual production: 1,100-1,200 kWh per kW installed
- 8 kW system: ~8,800-9,600 kWh/year
- Summer peak: June-August highest production
- Winter: Lower but cold temps help efficiency
Snow on panels is less of a problem than people think. Panels are installed at an angle and snow usually slides off. Even when covered, it is only a few days per year of lost production. Vermont cold actually helps—solar panels are more efficient in cold weather. Do not let winter scare you off.
The Bottom Line
Vermont proves that solar policy can overcome cloudy weather. With excellent net metering, group net metering options, state tax credits, and strong community solar programs, the Green Mountain State makes solar work. Higher electricity rates mean meaningful savings despite lower production. 7-10 year payback periods are realistic for most homeowners.
