An open house was held Thursday at the solar field inside the 180th Fighter Wing’s Ohio Air National Guard Base in Swanton. Nextronex Energy Systems offered a tour of the field. The company installed inverters at the 180th to help provide power to the base. There are already expansion plans because more power is needed to produce enough energy for the base. The solar panels produce about 700 kilowatts. The hope is to have the panels produce up to 1.4 megawatts.
