Solar Cells have been coming down in price roughly exponentially for 65+ years. Some have claimed that that was likely to halt as limits are reached with silicon cells. However, as often happens in technology advance, new paradigms can extend the exponential rate of decline for years or decades.
Now researchers have learned to produce Perskovite solar cells using manufacturing-grade printing techniques. This form of manufacturing can lead to cost-per-panel dropping to pennies instead of dollars, assuring that at least cost will continue to drop for about another decade. Efficiency isn't much different from current commercial panels (up to 22%); however, that too may improve over time.

As solar power generation drops to silly levels, all that remains is to produce batteries at sufficiently low prices that the cost of generation plus the cost of storage & release results in a price less than conventional generation.
We are nearly there.
