SolarCity will unveil three solar installations in Queen Anne's County this week that the company said are collectively the largest in the state not owned by a utility.

The installations include more than 14,000 solar panels and are capable of generating more than 3 megawatts of electricity, SolarCity said. That's enough to power about 300 Maryland homes for a year, according to the Solar Energy Industries Association.

Two solar farms were built for the town of Centreville and the third was built for the county, the San Mateo, Calif.- based company said.

SolarCity said the local governments won't own the installations but instead will buy the power, an increasingly common arrangement in the solar industry known as a power purchase agreement.
