Which is the effective battery technology choice, among Lead Acid and Li-Ion, in the context of Solar Direct Current Micro-grid?

Solar Direct Current (DC) Microgrid for remote areas is relatively an emerging area and there have been installations in different parts of the world. Battery is the obvious storage device for such applications. Any empirical results as to which one among Lead Acid/Li-Ion is effective in a comprehensive perspective say on life-cycle basis?
