Solar Lights and Lighting
Like appliances, lighting too can be powered by solar energy. In fact, for the vast majority of history, lighting was natural and therefore powered primarily by the sun. It wasn't until the 20th century that artificial lighting became the norm. Now however, we can power our artificial lighting with the sun. This may seem a little backwards, but because artificial lighting has become integral to everyday life in most places, it's at least better to power your lamps and track lighting with clean energy from the sun. As is, 20% of the energy used in the United States, and similar figures for other developed countries, is used to provide lighting. That means that if we all subsidized our lighting costs by using solar lighting, we'd have almost 20% less to pay in electricity bills! Day-lighting
Solar Electric Light Fund (SELF)The Solar Electric Fund (SELF) is a non-profit society that's main prerogative is to set up clean running, inexpensive solar power systems in developing nations. Many of the projects are developed in rural areas, that are too far away from the nearest electrical grid, as sometimes the sole source of electricity.

Daylighting is a passive method of solar lighting that uses sunlight to light up your home or business. This is usually done with sky-lights, well-placed windows, sawtooth roofs, light tubes, etc. With some minor, or major in some cases, adjustments to your home, you can fully light your home with daylight for much of the day.
