For proper looking daylight you'll need global illumination, to simulate
the indirect light from the blue sky. Classic raytracing alone won't
give you that, and POV-Ray's Photons implementation doesn't do GI
either. That leaves you with radiosity only.
You might try MCPov as an alternative, which uses stochastic ray tracing
instead of radiosity to compute GI. (Beware of a bug in MCPov though:
You'll need to set the "diffuse" parameter to twice the value you'd use
