Solar lighting
Solar lighting may be passive or active. Passive solar
lighting is basically natural solar light. A person may make use of
this technique through wise building construction with plenty of skylights.
For houses which have already been built, installing a solar tubular
light is a popular option to newly incorporate a skylight.
Active solar lighting options involve creating electricity to power
lights. This may refer to a solar panel system which provides the electricity
for all indoor lighting. It may also mean utilizing a smaller outdoor
panel to power a single indoor light.
More commonly, solar lighting it used for outdoor lighting. Walkway
lights and lamppost lights are common options for this technology. A
small built-in solar panel will absorb solar energy and save it within
a battery. At night, outdoor solar lights will generally automatically
turn on and run off the energy which they have collected during the
day.
