(Aurora, OR) -- Oregon State University is researching the best ways to incorporate solar power into farms. A one-and-a-half-million-dollar project is being built in Aurora that will test different designs. Solar panels can be installed at wider distances and with rotation systems, so they can be turned vertical while a tractor harvests a crop. Solar power on farms could product 20-percent of the power needed in the U.S. for an investment of less than one-percent of the annual U.S. budget.
