About The project

Slayton Solar has a nameplate capacity of 2.0 MW and is made up of 7,040 – 285 watt solar modules covering an area equal to approximately 7 ½ football fields. The Project is expected to produce an average of 2,620 MWh of energy per year, which is enough energy to power approximately 376 homes annually (the average consumption per household for this geographic region is 6,960 kWh). Slayton Solar was developed with a number of objectives, one of which was to identify the potential benfits (i.e. pricing, utilization of infrastructure, reliability, etc) of the complementary nature, or lack thereof, of wind and solar energy. Because of this objective, Slayton solar was constructed near the Buffalo Ridge in southwest Minnesota, which is home to some of the midwest's largest wind farms. To learn more about the goals and objectives of the Slayton Solar project, including an analysis of the potential benefits of collocating wind and solar, you can view Slayton Solar's final report on the Xcel Renewable Development Fund's website here: (link coming soon).

frequently asked questions

Is solar energy viable in the State of Minnesota?

While Minnesota doesn't have the solar resources like that of California, we have plenty of sun to make solar a viable and reliable energy resource for the State of Minnesota. Minnesota's solar insolation levels exceed that of Germany, Canada and other parts of the world where solar feed-in-tariffs have become common place and solar capacity far exceeds that of the majority of states in the United States. Solar energy is an excellent source of power during peak demand periods (i.e. summer weekdays), which helps alleviate stress on our aging and overworked transmission system. To learn more about solar energy resources in Minnesota, take a look through our resource links.

How much does solar energy cost?

The answer to this question is not a simple one. While on the surface, solar energy may seem much more expensive than fossil fuels, distributed generated solar energy has values beyond the cost of the energy being generated by the facility. Distributed generation refers to energy that is delivered directly in the electric lines that serve the homes and businesses that we live and work. This allows solar energy to bypass the expensive cost of sending the electricty over long distances through the utilitie's transmission infrastructure. Bypassing the transmission system not only saves money on future costs of upgrading transmission lines in Minnesota, but it also reduces energy demand during peak demand periods, which on a large scale could reduce the cost of market prices of fossil fuel generated by our utilites. While a study on this value has not been conducted in Minnesota, studies have concluded in other markets that the benefits of distributed generation solar far exceeds the cost to generate it. It would be inaccurate to state that subsidies aren't necessary to make solar viable in Minnesota, but if the true value of distributed generation solar energy can be accurately calcuated for the State of Minnesota, it could be found that solar energy pays for itself and then some.
