Your home may not be very well equipped to take in natural sunlight right now, but the potential is there and you can start by learning about the directions that light travels. Areas facing South, South East and South West, receive the most natural light throughout the day and year. South is the direction you want any new windows, glass doors, solar panels, etc. to face in order to make the most of your natural light settings. Areas facing the East will receive morning light with sunrise and areas facing the West will receive afternoon and evening light as the sun sets. North-facing windows are something you might want to avoid if you're looking for more light in your home because these areas, including North East and North West, do not receive direct sunlight.
