Solar power in the U.S. state of Vermont provides almost 11% of the state's in-state electricity production as of 2018. A 2009 study indicated that distributed solar on rooftops can provide 18% of all electricity used in Vermont. A 2012 estimate suggests that a typical 5 kW system costing $25,000 before credits and utility savings will pay for itself in 10 years, and generate a profit of $34,956 over the rest of its 25-year life.
Net metering is available for up to at least 500 kW generation, but is capped at 15% of utilities peak demand. Excess generation is rolled over each month but is lost once each year. Group net metering is also allowed. Vermont is given an A for net metering and a C for interconnection. A feed-in tariff was created in 2009, but is limited to 50 MW and is fully subscribed. The cap increases by 5 to 10 MW/year starting in 2013 until it reaches 127.5 MW in 2022. It is available for solar, wind, methane, and biomass. Seven solar projects are receiving payments, of $0.30/kWh, for 25 years.Monthly Production
Capacity factor for each year was computed from the end-of-year summer capacity.
2017 data is from Electric Power Monthly and is subject to change.
A small-scale 15KW installation at a homestead in middle Vermont generated 19,480 kWh of electrical energy at a Capacity Factor of 0.15. The homestead was sending energy to the utility when it was produced and taking energy from the utility when needed. Overall, the homestead consumed 80% of its generation and sold the remaining 20% to the utility. The generation profile is shown in the chart.
Beginning with the 2014 data year, the Energy Information Administration (EIA) has estimated the distributed solar-photovoltaic generation and distributed solar-photovoltaic capacity. These non-utility-scale appraisals evaluate that Vermont generated the following amounts of additional solar energy:

Solar farms
In 2012, Vermont had five solar arrays of at least 1 MW, the 2.2 MW SunGen Sharon 1 in Sharon, Vermont, Sharon. the 2.1 MW concentrating photovoltaics array installed in July 2011 in South Burlington, Vermont, South Burlington, the 1.5 MW photovoltaic array also in South Burlington installed in October 2011, the 1 MW photovoltaic array in Ferrisburgh, Vermont, Ferrisburgh, and the 2 MW Williamstown Solar Project. As of 2019, Green Mountain Power (GMP) has further constructed several solar arrays as large as 5 MW. In 2015, the 20 MW Coolidge solar farm near Ludlow was opposed by GMP, which claimed that there was no need for such utility-scale solar in the state. The farm was completed by NextEra Energy at the end of 2018.Generation
