GM and DTE Energy plan to build photovoltaic solar array at the General Motors Detroit-Hamtramck assembly plant in Southeast Michigan, US.

The 516kW solar project turns sunlight into electricity to help power the home of the Chevrolet Volt electric car.

The 264,000sq ft project is expected to be completed at the end of the year and will save the facility approximately $15,000 per year over the 20-year easement agreement.

The companies will build the array on a six-acre tract of land located on the south side of the plant.

The Detroit-Hamtramck installation is part of DTE Energy’s SolarCurrents pilot.

The power project will generate electricity capable of charging 150 of the electric cars with extended-range capability every day for a year.
