Power is almost always more expensive in the middle of the day. You can see this if you look at the energy component of the hourly electricity price (day ahead or real time) for any of the organized electricity markets (though you aren't totally wrong, the winter load profile does have a local minimum 14-17). Residential use lags in the midday but commercial + residential almost always peaks midday. In other words, solar generation occurs closer to peak pricing (i.e. solar electricity is more valuable electricity).
