The utility-scale plant will be constructed on abandoned farmland about 70 miles north of Los Angeles. It is expected to start commercial operations in June next year.
It will feature photovoltaic modules, related power electronics and other components such as an advanced solar tracking system.
The Springbok 1 project is expected to avoid about 300,000 metric tons of carbon dioxide (CO2) per year.
It has a power purchase agreement (PPA) with the Southern California Public Power Authority, on behalf of its participating member, the Los Angeles Department of Water and Power.
8minutenergy Renewables CEO Martin Hermann said: "This is an exciting day for everyone involved in the Springbok 1 project, as we move one step closer to providing clean energy to the people of Los Angeles.
"We began Springbok 1 in 2011, and the solar farm is yet another example of 8minutenergy delivering projects from conception to construction."
8minutenergy develops, finances, engineers, builds, owns, operates and maintains solar projects.
The company has so far won over 1.4GW in PPAs and secured more than 1.5GW in generation interconnection agreements.
