YES and it can ROI PV panels in less than 8 years at price of USD 0.1/kWh. Mining at solar energy must be backed by either battery or grid electricity. Your PV panels can be directly connected to miners (grid PSU also) and voltage of PV controller should be few mV higher than grid PSU, so all energy from PV will be used to power miners even at cloudy, the rest will be backed by grid.

This model keeps your miners stable voltage and running smoothly, but when used with "string design" miners like Antminer S5 or S4+, it needs additional DC-DC convertor. By the way, this model reduces investment by missing expensive grid invertor.
