“Solar powered lights are best suitable for exterior space lightening.”

Why? Cant we use solar direct from sun with same system to manage interior lighting…a simple step in converting the home without enormous overhead?

Thanks for the info on concentrator panels, I am interested in knowing which is the state of the art technology and the merits of various options.

Is there commercial suppliers at this stage as such…is not the heat captured from cooling another thermal advantage if it can be added to the captured system.
