How can the electricity yield from solar power plants be increased significantly?

A MW of a solar farm in a sunny region generates about 1.5 million units of electricity every year. This implies a capacity utilization factor (CUF) of less than 20% - that is, less than 20% of the total generation capacity of the solar panels is utilized to produce electricity. What technologies, designs and processes can significantly increase the CUF to yield higher levels of electricity from the same solar farm?
