Customers are paying prices, not costs. A cheap kWh of solar electricity isn't useful when it's not available when needed. Prices are mandated by supply and demand. Also, while the costs of the solar modules may fall further, the costs for the whole setup does not. A solar power plant requires a lot of mechanical and electrical parts to get the solar modules installed and connected to the electricity grid plus labor costs.
