For daytime use -- there's a guy (I think on You tube) that effectively lights his home but poking clear liter water bottles (full of water and some chlorine) through the roof and letting them hand down half way. Kind of like the solar tubes or sky lights. Not sure what happens when it rains but the water magnifies the light and it works pretty good.
Other than that, I suppose a large mirrors like in the old Egyptian tomb movies or lots of windows or setup your kitchen near the windows or cook outside under a canopy.
At night crank or shake flash lights?
There are various generator systems but they require research, the right skills and time.
